The speaker module according to an embodiment of the present invention is provided, and will be specifically described with reference to fig. 1 to 4.
In an embodiment of the present invention, the speaker module includes:
the module comprises a module shell 100, wherein an accommodating cavity, a first mounting position and a second mounting position are arranged in the module shell 100;
the sound-producing unit 200 is arranged at the first installation position so as to divide the accommodating cavity into a front sound cavity and a rear sound cavity, and the rear sound cavity is filled with sound-absorbing particles 300; and the number of the first and second groups,
the breathable isolation assembly 400 comprises an isolation frame 410 and a breathable isolation piece 420 installed on the isolation frame 410, wherein the isolation frame 410 is sleeved at one end, located in the rear sound cavity, of the sound-emitting unit 200 and is installed at the second installation position, and the breathable isolation piece 420 covers one side, away from the front sound cavity, of the sound-emitting unit 200 so as to separate the sound-emitting unit 200 from the sound-absorbing particles 300; wherein,
the sound production monomer 200 with first installation position is glued 500 bonds through photosensitive adhesive, just isolation frame 410 is for supplying the solidification photosensitive adhesive 500's light transmission's printing opacity isolation frame.
Specifically, the module housing 100 includes a module front shell 110 and a module rear shell 120 which are connected, the module front shell 110 and the sound generating unit 200 enclose the front sound cavity, and the module rear shell 120, the sound generating unit 200 and the module front shell 110 enclose the rear sound cavity. Wherein, shell 110 before the module is all located to first installation position and second installation position, and shell 110 before the module is installed in the module to sound production monomer 200 promptly, bonds through photosensitive glue 500 between shell 110 before sound production monomer 200 and the module. The isolation frame 410 is sleeved on the periphery of the sounding unit 200 and is mounted to the second mounting position, and the isolation frame 410 is fixedly connected with the module front shell 110, specifically, the isolation frame 410 and the module front shell can be fixedly connected through a fastening connection, a gluing bonding connection and other modes. In addition, the sounding unit 200, the isolation frame 410 and the module front case 110 may be glued together, as will be described in detail below.
It can be understood that the initial state of the photosensitive adhesive 500 is liquid, and after the photosensitive adhesive 500 is cured by light irradiation, the photosensitive adhesive 500 has sufficient viscosity, so that the two bonding surfaces are firmly bonded. In the related art, in order to avoid blocking of the isolation frame 410 to light, after the sound generating unit 200 is adhered to the front module shell 110 through the photosensitive adhesive 500, the photosensitive adhesive 500 is irradiated by the light to be in a semi-cured or cured state, and then the isolation frame 410 is sleeved on the periphery of the sound generating unit 200 and is installed at the second installation position of the front module shell 110. As such, once the photosensitive adhesive 500 on the module front case 110 is excessively coated or the photosensitive adhesive 500 on the peripheral side of the sound generating unit 200 is excessively coated, unevenness occurs at the second mounting position of the module front case 110 or the peripheral side of the sound generating unit 200, so that the spacer frame 410 is easily lifted up, thereby causing the spacer frame 410 to be not assembled in place.
In the technical solution of the present invention, a first installation position and a second installation position are disposed in the module housing 100, the sound generating unit 200 is installed at the first installation position, and the isolation frame 410 is sleeved on the sound generating unit 200 and installed at the second installation position. Wherein, the sound generating unit 200 is bonded to the first mounting position by the photosensitive adhesive 500, and the isolation frame 410 is a light-transmitting isolation frame through which light rays for curing the photosensitive adhesive 500 can pass. Thus, after the photosensitive adhesive 500 is coated and the sound generating unit 200 is mounted to the first mounting position of the module housing 100, the photosensitive adhesive 500 is not cured, but the isolation frame 410 is mounted to the second mounting position of the module housing 100, and then the light penetrates through the isolation frame 410 to irradiate the photosensitive adhesive 500 to be cured. Therefore, the sound-emitting single body 200 can be effectively fixed, the isolation frame 410 can be assembled in place, and the situation that the isolation frame 410 is jacked up due to the fact that the photosensitive adhesive 500 is coated too high is effectively avoided.
Further, as shown in fig. 2 and 4, the spacer frame 410 is adhered to the second mounting site by a photosensitive adhesive 500. It is understood that the second mounting position is formed at the module front case 110, and the spacer frame 410 is adhered to the module front case 110 by the photosensitive adhesive 500. Specifically, the first mounting position and the second mounting position are close to each other, or connected to each other, or partially overlapped. When installation sound production monomer 200 and isolation frame 410, can locate coating photosensitive glue 500 in the lump at first installation position and second installation, again with sound production monomer 200 and isolation frame 410 one and install to the module in the shell 110 before, last reuse light shines photosensitive glue 500 to the solidification, so, can guarantee that sound production monomer 200 is effectively fixed, can guarantee again that isolation frame 410 is fixed in step and assemble in place. Between shell 110 before this embodiment technical scheme through making sound production monomer 200 and the module, all bond through photosensitive glue 500 between isolation frame 410 and the module front shell 110, can make sound production monomer 200 and isolation frame 410 can be fixed in shell 110 before the module simultaneously, and then simplify process flow, promote assembly efficiency.
In this embodiment, as shown in fig. 2 and 4, a supporting frame 111 is disposed in the module front case 110, the second mounting position is an end surface of the supporting frame 111 facing the module rear case 120, and an end surface of the isolation frame 410 facing the module front case 110 is bonded to the second mounting position through a photosensitive adhesive 500, that is, an end surface of the isolation frame 410 facing the module front case 110 is bonded to an end surface of the supporting frame 111 facing the module rear case 120. It can be understood that the supporting frame 111 is arranged in the module front shell 110 in a protruding manner, so that an accommodating space is provided for the sound generating unit 200, and meanwhile, a supporting structure is provided for the isolation frame 410, so that the isolation frame 410 is conveniently butted with the module front shell 110. And, through making between the support frame 111 and the isolation frame 410 bond through photosensitive glue 500, make between isolation frame 410 and the module front shell 110 fixed connection, and make the clearance between isolation frame 410 and the support frame 111 sealed, in order to further isolate between sound monomer 200 and the sound absorption granule.
Specifically, a plurality of first protrusions (not shown) are formed at one end of the partition frame 410 facing the front module case 110, a plurality of second protrusions (not shown) are formed at one end of the support frame 111 facing the rear module case 120, and the plurality of first protrusions and the plurality of second protrusions are in one-to-one contact. Specifically, the isolation frame 410 and the support frame 111 are provided with convex portions at part of the frame edges and part of the corners, and concave portions are formed between the convex portions, so that when the convex portions of the isolation frame 410 are in one-to-one butt joint with the convex portions of the support frame 111, the concave portions of the isolation frame 410 and the concave portions of the support frame 111 are in one-to-one correspondence and form glue coating gaps. In this embodiment, the isolation frame 410 and the support frame 111 are bonded by glue, and a glue coating gap is formed between the isolation frame 410 and the support, so that more glue can be conveniently coated between the isolation frame 410 and the support frame 111, thereby improving the tightness of the fixed connection between the isolation frame 410 and the support frame 111. Of course, in other embodiments, the isolation frame 410 and the support frame 111 may not be configured to have an uneven structure, i.e., the connection surface between the isolation frame 410 and the support frame 111 is a flat surface.
It can be understood that if the isolation frame 410 is an opaque isolation frame 410, the light is difficult to directly irradiate the bonding surface between the isolation frame 410 and the support frame 111 from top to bottom, which may result in a prolonged light curing time of the photosensitive adhesive 500 or increase the process difficulty due to the need to adjust the light irradiation angle. In the technical scheme of the embodiment, the isolation frame 410 is a light-transmitting isolation frame for light rays for curing the photosensitive adhesive 500 to penetrate through, so that the light rays can penetrate through the isolation frame 410 to irradiate the photosensitive adhesive 500 positioned on the bonding surface of the isolation frame 410 and the support frame 111, the photocuring time of the photosensitive adhesive 500 can be effectively shortened, the light rays can be directly irradiated from top to bottom, and the process difficulty is reduced.
Further, the first mounting position is an inner side surface of the supporting frame 111, and the outer peripheral surface of the sound generating unit 200 is bonded to the first mounting position through the photosensitive adhesive 500, that is, the sound generating unit 200 is bonded to the supporting frame 111 through the photosensitive adhesive 500. It can be understood that a sealant is generally coated between the bottom of the sounding unit 200 and the front case 110, but the sealant mainly plays a role in sealing, and the fixing function is not obvious. Among this embodiment technical scheme, through between the terminal surface at carriage 111 and isolation frame 410, between the medial surface of carriage 111 and sound production monomer 200, all bond through photosensitive adhesive 500 between the medial surface of isolation frame 410 and the sound production monomer 200, so, after having scribbled photosensitive adhesive 500, just can install sound production monomer 200 and isolation frame 410 in the shell 110 before the module earlier, all photosensitive adhesive 500 to the solidification are shone through the printing opacity isolation frame to light reuse light at last, thereby can fix sound production monomer 200 and isolation frame 410 in the lump, and can ensure that isolation frame 410 assembles in place.
In one embodiment, the air-permeable spacer 420 is a light-permeable spacer that can be penetrated by the light rays of the curing photosensitive adhesive 500. Thus, before light rays penetrate through the light-transmitting isolation frame to irradiate the photosensitive adhesive 500 between the sound-emitting monomer 200 and the module front shell 110 to be cured, the air-permeable isolation piece 420 can be installed and combined to the end face of the isolation frame 410, and even if the air-permeable isolation piece 420 covers one ends of the sound-emitting monomer 200 and the isolation frame 410, the optical fibers are not basically prevented from irradiating the photosensitive adhesive 500 to influence the curing of the photosensitive adhesive 500. Moreover, the breathable isolation piece 420 and the isolation frame 410 are combined into a whole and then are installed in the module front shell 110, so that the installation difficulty of the breathable isolation piece 420 can be reduced, and the assembly time of the whole machine is reduced. It will be appreciated that the breathable barrier 420 is typically a breathable barrier web that also transmits light but has a relatively low light transmittance. In this embodiment, the light-transmitting spacer can be made of a transparent material to improve the light transmittance of the air-permeable spacer 420.
In this embodiment, the photosensitive adhesive 500 is a UV photosensitive adhesive, and correspondingly, the isolation frame 410 is a light-transmitting isolation frame capable of allowing UV light to pass through. It is understood that the photoinitiator in the UV light-sensitive adhesive can generate active radicals or cations after absorbing UV light under the irradiation of UV light, and initiate the chemical reaction of monomer polymerization and crosslinking, so that the photosensitive adhesive 500 can be converted from a liquid state to a solid state in a short time. Of course, in other embodiments, the photosensitive adhesive 500 may be other types of photosensitive adhesives, and curing may be initiated by absorbing other types of light besides ultraviolet rays, and correspondingly, the isolation frame 410 is a light-transmissive isolation frame through which other types of light can pass.
Optionally, the isolation frame 410 is made of a transparent colorless material or a colored material that transmits UV light. It is understood that the isolation frame 410 may be made of a transparent colorless material, so that the isolation frame 410 may allow all light rays including UV light to pass through; alternatively, the isolation frame 410 may be made of a colored material that transmits UV light, and the isolation frame 410 only transmits UV light.
Alternatively, the spacer frame 410 may be made of any one of Polycarbonate (PC), Polystyrene (PS), Styrene Acrylonitrile (SAN), organic glass (polymethylmethacrylate, PMMA), and the like. The materials are transparent plastics with good light transmittance, and in other embodiments, the isolation frame 410 may also be made of other materials, such as transparent inorganic glass. This embodiment technical scheme is through adopting the isolation frame 410 of making by the better material of luminousness, can effectively shorten photosensitive glue 500 photocuring's time to promote speaker module's assembly efficiency.
The embodiment of the present invention further provides a manufacturing method of a speaker module, which is shown in fig. 5 and includes the following steps:
s1, coating photosensitive adhesive on a first mounting position and/or a sounding monomer of the module shell, wherein the first mounting position is used for mounting the sounding monomer, and mounting the sounding monomer to the first mounting position;
s2, sleeving the isolation frame on the sounding single body until the isolation frame is installed on a second installation position of the module shell for installing the isolation frame; the isolation frame is a light-transmitting isolation frame which can be penetrated by light rays for curing the photosensitive adhesive;
and S3, irradiating the photosensitive adhesive between the sounding monomer and the module shell to cure by using light rays penetrating through the light-transmitting isolation frame, so that the sounding monomer is adhered to the module shell.
It can be understood that the isolation frame is a light-transmitting isolation frame which can be penetrated by light rays for curing the photosensitive adhesive. So, having scribbled photosensitive glue to with the sound production monomer adorn to the first installation position of module shell after, can not solidify photosensitive glue earlier, but with the second installation position of isolation frame dress to module shell earlier, use light to shine photosensitive glue to the solidification through non-light tight isolation frame again. Therefore, the sounding unit can be effectively fixed, the isolation frame can be assembled in place, and the situation that the isolation frame is jacked up due to overhigh coating of the photosensitive adhesive is effectively avoided.
Further, before the step of sleeving the isolation frame on the sound generating unit and installing the isolation frame on the second installation position of the module shell for installing the isolation frame, the manufacturing method of the speaker module further comprises the steps of: and coating photosensitive glue on a second mounting position for mounting the isolation frame and/or the isolation frame of the module shell. Can understand when installation sound production monomer and isolation frame, can install position department at first installation position and second and coat the photosensitive glue in the lump, adorn sound production monomer and isolation frame to the module in the shell before again in the lump, light irradiation photosensitive glue to solidification is used again at last, so, can be so that sound production monomer and isolation frame are fixed by synchronous.
In an embodiment, before the step of irradiating the photosensitive adhesive between the sound generating unit and the module housing to cure by using light to pass through the light-transmissive separation frame, so as to adhere the sound generating unit to the module housing, the method for manufacturing the speaker module further includes the steps of: mounting the breathable isolating piece on the isolating frame; the breathable isolating piece is a light-transmitting isolating piece which can be used for curing light rays of the photosensitive adhesive to penetrate through. Generally, this step occurs before the step of placing the isolation frame over the sound unit until the isolation frame is mounted to the second mounting position of the module housing for mounting the isolation frame. That is to say, pass the printing opacity isolation frame at adoption light to shine before the photosensitive glue between sound production monomer and the module front shell to the solidification, just can combine the terminal surface of isolation frame with ventilative isolator installation earlier, even ventilative isolator covers the one end at sound production monomer and isolation frame, also can not block optical fiber irradiation to photosensitive glue basically and influence the solidification of photosensitive glue. And, combine ventilative separator and isolation frame earlier as an organic whole, install to the module in the shell before, also can reduce the installation degree of difficulty of ventilative separator to reduce the assemble duration of complete machine.
In an embodiment, after the step of irradiating the photosensitive adhesive between the sound generating unit and the module housing with light through the light-transmissive separation frame until curing, so as to adhere the sound generating unit to the module housing, the method for manufacturing the speaker module further includes the steps of: and installing the breathable isolating piece on the isolating frame. It can be understood that, among the technical scheme of this embodiment, owing to after photosensitive glue solidification, again with ventilative separator install in isolation frame, so, ventilative separator only need adopt ordinary ventilative isolation screen cloth can, and need not to adopt the printing opacity material.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention, and all modifications and equivalents of the present invention, which are made by the contents of the present specification and the accompanying drawings, or directly/indirectly applied to other related technical fields, are included in the scope of the present invention.
