detailed description

The content of the present invention will be described in detail below with reference to the accompanying drawings:

Example:

Fig. 1 shows an exploded view of a portion of the structure of the earphone of the present invention, mainly the structure of the earplug portion. Referring to FIG. 1, the earphone of the present invention comprises an earphone housing 1 and a cover assembly 2, and the earphone housing 1 and the cover assembly 2 are matched and coupled to each other to form a receiving cavity, and the receiving cavity contains the earphone. Sound unit - speaker unit 3. Like the conventional speaker unit, the speaker unit 3 also includes a magnetic circuit system and a vibration system, wherein the vibration system includes a voice coil and a diaphragm, and the voice coil is received outside. After the current signal, the reciprocating cutting magnetic field will be moved under the action of the electromagnetic field to drive the diaphragm to vibrate and radiate the sound to the outside. In the present embodiment, the space between the diaphragm in the speaker unit 3 and the cover assembly 2 forms a front acoustic cavity, and the space between the diaphragm and the earphone housing 1 forms a rear acoustic cavity. The above-mentioned several structures are not substantially different from the conventional earphones, and the improvement of the technical solution will be highlighted in the following sections:

As shown in FIG. 1 , the cover assembly 2 is formed by a two-part structure, and specifically includes a front cover 21 and a sound output tube 22 combined with the front cover 21, in order to facilitate the smooth transmission of sound waves generated by vibration of the diaphragm, Both the cover 21 and the sound output tube 22 are designed to be open at both ends, and since the cover assembly 2 needs to be assembled with the earphone housing 1, it is obvious that the end face of the cover assembly 2 and the earphone housing 1 should be assembled. The fixed end-matching design is similar. Similarly, the end face of the sound-emitting cylinder 22 and the front cover 21 should also be designed to facilitate assembly and fixation. When implemented, the sound-emitting cylinder 22 and the front cover 21 can be glued. The knot is fixed and can also be fixed by ultrasonic welding. The front cover 21 is provided with a sound venting hole 214. This structural design is similar to the design in the prior art, and it does not greatly help the purpose of adjusting the sound quality effect of the technical solution, and is really used for tuning tuning. The structure specifically includes a tuning hole 213 and a tuning member 4 disposed in the front acoustic cavity.

2 and 3 respectively show a top view of the front cover 21 and the sound emission tube 22, as shown in the exploded view of FIG. 1, it can be seen that the bottom end of the front cover 21 specifically includes a curved surface area 211 and a rectangular shape. The facing area 212, and the tuning hole 213 for tuning is located on the straight surface area 212; the sound emitting tube 22 is a cylindrical structure, and one end of the front cover 21 is assembled with the front cover 21, and the adjustment end is adjusted. The sound member 4 is coupled to the fitting end of the sound output tube 22. Further, a notch 222 formed by the blank is disposed at a position where the fitting end of the sound emitting tube 22 is close to the outer edge, and a rectangular straight portion 221 is provided at a side of the notch 222 near the center of the mounting surface, and the straight surface 221 described here is 221 Cooperating with the notch 222 to form a card matching plane, the tuning member 4 is snap-fitted and fixed on the card matching plane.

Referring to FIGS. 5 and 7, the tuning member 4 specifically includes a push handle 41 and is disposed perpendicular to the push handle 41. The slider 42 and the slider 42 are housed in the straight surface portion 221 of the sound emission tube 22. After the tuning member 4, the sound-emitting tube 22, and the front cover 21 are assembled, since one end of the sound-emitting straight portion 221 and the tuning hole 213 at the bottom end of the front cover 21 correspond to each other, the other end and the tuning hole 213 are offset from each other. Therefore, if the push handle 41 of the tuning member 4 is pushed, the push handle 41 drives the slider 42 to move together, and the slider 42 is along the straight portion 221 in two opposite directions (that is, both ends of the straight portion 221) Between) horizontally reciprocating sliding.

Specifically, FIG. 4 and FIG. 5 show an operation state of the earphone of the present invention, and the slider 42 slides to the deviation end of the straight surface portion 221 and the tuning hole 213 (shown as the horizontal left end in FIG. 5), which can be avoided. The tuning hole 213, therefore, the tuning hole 213 is in a conductive state, at this time, the earphone will present a musical style; FIG. 6 and FIG. 7 show another working state of the earphone of the present invention, the slider 42 slides To the corresponding end of the straight face 221 and the tuning hole 213 (shown as the horizontal right end in FIG. 7), the slider 42 blocks the tuning hole 213 (shown as a broken line in the figure), and at this time, the tuning hole 213 will be at In the closed state, the headphones show a different style of music. Through the above process, the adjustment effect of the earphone headphone sound quality effect (changing the frequency response parameter of the earphone low frequency) can be realized to meet the different needs of more consumers.

It should be noted that the earphone of the present invention shown in this embodiment has two gear positions. In specific implementation, the gear position can be increased according to actual needs, when the slider of the tuning member slides to different positions of the tuning hole. When the headphones are presented, a variety of different musical effects are presented. In addition, it should be noted that the above is only an exemplary description of the present embodiment, and the specific position of the tuning structure involved, the specific design of the bottom end of the front cover, and the specific design of the assembly end of the sound tube are not limited. The technical solution is implemented as long as the tuning hole is provided in the front acoustic cavity, and the slidable tuning member is provided, and the tuning hole is turned on or closed by the sliding of the tuning member.

In the earphone of the present invention, the tuning member 4 is preferably made of hard rubber or soft rubber.

In addition to the above structure, the earphone of the present invention has a mesh cloth 5 attached to the end surface of the sound output tube 22 away from the front cover 21, which can be used for dustproofing and tuning. The mesh 5 described herein is a four-layer composite structure, and specifically includes a metal mesh, a first adhesive layer, a mesh mesh, and a second adhesive layer, wherein the first adhesive layer is used for bonding and fixing the metal mesh and the mesh mesh, The second adhesive layer is used for bonding and fixing to the end surface of the sound emission tube 22. Of course, mesh 5 can also be designed as other specific structures, and is not limited to this.

The earphone of the present invention further includes an earplug sleeve 6 sleeved on the outer side of the earplug. The earplug sleeve 6 is generally a soft material, such as a silica gel. In addition, the earphone housing 1 is also combined with a sleeve 7 (also denoted as SR). The sleeve 7 is preferably made of a soft rubber material, and the connection between the earplug portion and the earphone audio signal line can be realized through the sleeve 7.

The above is only the embodiment of the present invention, and is not intended to limit the present invention, and equivalent modifications or variations made by those skilled in the art in light of the present invention are included in the scope of the claims.
