Embodiments of the invention

 DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In order to further explain the principles and structures of the present invention, the preferred embodiments of the present invention will be described in detail.

 [0032] The earphone of the present invention may be an ear-in-ear earphone or an electronic device such as a Bluetooth in the application, and is not specifically limited herein.

 Referring to FIGS. 1 and 2, the earphone 10 of the present embodiment includes: a housing 11, at least two speakers 12, an earloop 13, a trigger unit 14, and a control unit 15.

[0034] The housing 11 is provided with a sound outlet 113 on both the first surface 111 and the opposite second surface 112. At least one speaker 12 is disposed on the sound outlet 113 of the first surface 111 of the casing 11, and at least one speaker 12 is disposed on the sound outlet 113 of the second surface of the casing 11. The earloop 13 is fixed to the housing 11. The earhook 13 includes a hook body portion 131 that is bent to be worn in the shape of the auricle root. The two speakers 12 are respectively located on both sides of the plane in which the hook main body portion 131 is located. The trigger unit is disposed in the inner or outer surface of the housing 11, and is triggered by a human control or self-induction. The control unit 15 is disposed in the housing 11 and receives the trigger signal to select the switching speaker 1 2.

 In the earphone 10 of the present invention, at least two speakers 12 are disposed opposite to the front and back sides of the casing 11, and the speaker 12 on one side corresponds to one side of the ear. Then, when the user needs to transfer the earphone 10 from one ear to the other, it is easy to remove the earphone 10 from one ear and quickly wear it to the other ear without using the earphone 10 Make any changes and replace them directly. Further, the hook main body portion 131 has a bending direction with respect to the left ear and a bending direction with respect to the right ear, and is bent from the front side toward the back of the ear. The two speakers 12 are respectively located on both sides of the plane in which the hook main body portion 131 is located. When the speaker 12 located on the first surface 111 or the second surface 112 of the casing 11 is used, the earloop 13 can be worn on the left or right of the user. The user can quickly switch between the left and right ears, saving the user from wearing the ear.

 [0036] Moreover, the earphone 10 of the present invention selects the speaker 12 corresponding to the switching side by the trigger unit 14 and the control unit 15, and the control unit 15 according to the trigger signal issued by the trigger unit 14. The control unit 15 receives the trigger signal of the one-side trigger unit 14 and compares it with the threshold according to the type of the trigger signal. When the value of the trigger signal reaches the threshold, the control unit 15 issues a control signal to turn on the speaker 12 corresponding to the side trigger unit 14 to turn on. Therefore, the earphone 10 can intelligently sense which side of the speaker 12 is used by the user, thereby automatically controlling the switching between the two speakers, assisting the switching between the left and right ears, and improving the user experience.

 [0037] The housing 11 is for carrying and receiving components of the earphone 10. The housing 11 may be a closed housing 11 having a certain receiving space, or may be a frame structure having a certain supporting capacity. The housing 11 includes a first surface 111 and a second surface 112. Herein, the first surface 111 and the second surface 112 are named only for convenience of explanation, and do not define the specific shape and manner of use of the housing 11. The housing 11 is provided with an acoustic opening 113 at its first surface 111 and second surface 112.

[0038] The housing 11 is housed in the outer ear door of the ear. The shape of the housing 11 matches the shape of the outer ear door of the ear to ensure the reliability and comfort of the earpiece 10. Specifically, in the present embodiment, the casing 11 is a flat casing, and a receiving cavity is formed. The housing 11 includes two sealing plates 14 14 opposite to the first surface 111 and the second surface 112. The two sealing plates 114 are connected by a side plate 115. The sound outlet 113 is disposed on the sealing plate 114. Specifically, the housing 11 includes a large end 116 and a small end 117. The shape of the sealing plate 114 is substantially trapezoidal. The sound outlet 113 is disposed at a position near the small end 117 of the sealing plate 114, and thus the speaker 12 is located at the small end 117 of the housing 11. When the housing 11 is worn on the ear, so that the speaker 12 is close to the entrance of the external auditory canal, the sound effect of the earphone 10 is ensured.

[0039] It should be noted that the shape of the housing 11 and the sealing plate 114 and the limitation of the position of the sound outlet 113 are only preferred embodiments of the present invention, but are not limited thereto. The body 11 and the sealing plate 114 may be any shape that can be fixed to the ear, and the sound outlet 113 may be located at other positions of the housing 11, which are not exhaustive.

 [0040] The speaker 12 is a transducing device that converts an electrical signal into an acoustic signal. The speaker 12 includes a first speaker 121 disposed at the sound outlet 113 of the first surface 111 and a second speaker 12 2 provided with the sound outlet 113 of the second surface 112. The first speaker 121 and the second speaker 122 operate relatively independently. In other embodiments, the earphone 10 may include a plurality of speakers of other functions in addition to the first speaker 121 and the second speaker 122 described above. For example, a tweeter for playing a high pitch, a woofer for playing a bass, and the like. The headphone 1 0 enhances the sound of the headphone 10 through a multi-function speaker.

 [0041] The earloop 13 is intended to be worn on the auricle of the user. The shape of the earloop 13 matches the shape of the auricle. Also, the earhook 13 is made of a shapeable material. It will be understood that the surface of the earhook 13 is a ductile cladding. The cladding may be a material such as rubber or resin. A core material capable of maintaining a shape is provided inside the cladding. The core material may be a copper core or an aluminum core. The earhook 13 can also be made of other materials that can be shaped, not listed here.

[0042] The earhook 13 can be flexibly deformed according to the size of the user's ear to be freely adjusted to fully conform to the user's auricle. The earhook 13 is fully ergonomic and fits perfectly into the shape of the ear, taking into account the fixability and reliability of the wear.

 Specifically, in the present embodiment, one end of the earloop 13 is connected to the side plate 115 such that the two speakers 12 are respectively located on both sides of the plane of the hook main body portion 131. That is, the earloop 13 is located at the middle of the two speakers 12. When the earphone 10 is worn on either side of the ear, the earloop 13 is at the same distance from the left ear or the right ear. Therefore, when the earphone 10 is replaced with the ear, the wearing effect of the earloop 13 is not affected.

 Specifically, in the present embodiment, the earphone 10 is a wired earphone, and the earloop 13 is bent by a signal line 132 connected to the casing 11, and the signal line is bent near the casing 11 to constitute the hook main body portion 131.

[0045] Referring to FIG. 3, in other embodiments, the earphone 20 is a Bluetooth earphone, and the earloop 23 is a fixing member directly disposed on the casing 21 of the Bluetooth earphone 20, and is worn on the auricle of the ear. [0046] Referring to FIG. 4, specifically in the present embodiment, the earphone 10 further includes an arc-shaped ear cover 16. The earmuffs 16 are fixed to the large end 116 of the housing 11 and are skewed toward the fixed position of the earloop 13 and the housing 11. The ear cover 16 is used to assist the housing 11 to be stably received in the outer ear door of the ear. The earmuff further ensures the reliability of the earphone 10

[0047] Moreover, both ends of the ear cover 16 are fixedly disposed on the side plate 115. That is, the ear cover 16 is located at an intermediate position between the two speakers 12. When the earphone 10 is worn on either side of the ear, the ear cover 16 is the same distance from the left ear or the right ear, and therefore, when the earphone 10 is replaced with the ear, the wearing effect of the ear cover 16 is not affected.

 [0048] Specifically, in the present embodiment, the ear cover 16 is a silicone earmuff. The ear cover 16 is bent into a curved annular structure by a strip of elongated silicone. One end of the silicone strip is fixedly disposed at the large end 116 of the housing 11, and the other end is adjacent to the fixed position of the earloop 13 and the housing 11. An end of the silicone strip adjacent the large end 116 extends along the outer surface of the side panel 115 to cover the outer surface of the side panel 115 at the large end 116. When the earphone is worn on the ear, the housing 1 1 is housed in the outer ear door to prevent the side panel 115 from directly contacting the skin of the ear. Since the silicone earmuffs are soft and close to the human skin, they do not wear the user's ears and enhance the comfort of use.

 [0049] It can be understood that, in practical applications, the material of the earmuffs 16 is other well-known elastic materials in the prior art, such as natural rubber, resin, etc., which are not exhaustive.

 [0050] Referring to FIG. 2, the trigger unit 14 is configured to issue a trigger signal. Specifically in the present embodiment, the trigger unit 14 includes an inductive element 141 that changes its own circuit characteristics by approaching or contacting the human body. Circuit characteristics can be resistance, voltage, current, capacitance, etc. The sensing element 141 is at least two, and at least one sensing element 141 is adjacent to the first surface 111 of the housing 11, and at least one sensing element 141 is adjacent to the second surface 11 2 of the housing 11. That is, at least two sensing elements 141 are respectively used to sense the distance between the first surface 111 of the casing 11 and the human body, and the distance between the second surface 112 of the casing 11 and the human body.

 [0051] Specifically, in the present embodiment, the sensing element 141 is a conductive metal element. The metal component acts as a pole of the capacitor, and the human body is equivalent to the earth. As the other pole of the capacitor, the metal component forms a capacitor together with the human body. When the human body is close to the metal component 吋, the capacitance value of the capacitance of the metal component and the human body changes, the trigger unit 14 generates a level signal as a trigger signal output.

[0052] Specifically, in the present embodiment, the metal element is a copper foil. The copper foil is in the form of a sheet or a ring and is disposed inside the housing cavity of the housing 11. The metal member is not limited to copper foil, and may be aluminum foil, gold foil or the like. Due to the conductivity of copper Good to improve the sensitivity of the metal components and the human body to form a capacitor. It can be understood that the material of the metal component can be other known conductive metal materials in the prior art, which are not exhaustive.

[0053] In practical applications, the sensing element 141 may be a capacitive sensor disposed within the housing 11. Capacitive sensors convert measured mechanical quantities, such as displacement, pressure, etc., into capacitance changes. The human body approaches or touches the capacitive sensor, and the capacitance of the capacitive sensor changes. The trigger unit 14 issues a trigger signal according to the change in capacitance.

 [0054] In other embodiments, the sensing element 141 is a resistive sensor or an inductive sensor.

[0055] Specifically, the resistive sensor can convert non-electrical physical quantities such as displacement, force, pressure, acceleration, and torque into resistance value changes. When the resistive sensor is used as the sensing element 141, the resistance value of the resistive sensor changes by the human body touching the resistive sensor. The trigger unit 14 emits a trigger signal according to the change in the amount of resistance.

 [0056] The inductive sensor converts the measured physical quantity such as displacement, pressure, flow, vibration, etc. into a change in the self-inductance coefficient and the mutual inductance of the coil by electromagnetic induction, and then converts the circuit into a voltage or current change output. When the sensing element 141 is an inductive sensor, the human body touches the inductive sensor, and the voltage or current value of the inductive sensor changes. The trigger unit 14 issues a trigger signal depending on the change in voltage or current value.

 [0057] It should be noted that the above-mentioned limitation of the sensing element 141 is only a preferred embodiment of the present invention, but it is not limited thereto. The sensing element 141 can be any one that can be changed by approaching or contacting with a human body. Electronic components of their own circuit characteristics are not exhaustive here.

[0058] In other embodiments, the trigger unit 14 is an inductive element 141 that generates an inductive signal by approaching or contacting the human body. The sensing signals include infrared signals, photoelectric signals, and thermal signals. The sensing element 141 is an infrared sensor, a light sensor or a thermal infrared body sensor.

[0059] Specifically, when the sensing element 141 is an infrared sensor 吋, the infrared sensor emits a beam of infrared light to the human body, and the infrared ray is reflected back by contacting the skin. The reflected infrared beam senses the distance from the human body to generate an inductive signal. Based on the sensing signal, the trigger unit 14 issues a trigger signal. The infrared sensor can be an infrared photodiode.

[0060] When the sensing element 141 is a light sensor, the light sensor can sense ambient light conditions. When the human body approaches or touches the light sensor, the light around the light sensor changes, and the sensor The distance between the human body and the induced signal is generated. Based on the sensing signal, the trigger unit 14 issues a trigger signal. The light sensor can be a photodiode.

[0061] Also, the thermal infrared human body sensor is an infrared pyroelectric sensor capable of detecting a stationary human body. When the human body approaches or contacts the thermal infrared human body sensor, the photosensitive element can generate a polarization differential, and the photosensitive circuit sends a human identification signal to generate an induced signal. Based on the sensing signal, the trigger unit 14 issues a trigger signal.

[0062] It can be understood that the sensitivity of the trigger unit 14 of the earphone 10 is enhanced, or the use condition of the trigger unit 14 is improved. The first surface 111 or the second surface 112 adjacent to the housing 11 may be provided with a plurality of different types of sensing elements 141.

 [0063] It should be noted that the above-mentioned limitation of the sensing element 141 is only a preferred embodiment of the present invention, but it is not limited thereto. The sensing element 141 can be any capable of generating an induction by approaching or contacting with a human body. The electronic components of the signal are not exhaustive here.

 [0064] It can be understood that the trigger unit 14 can also be a switch button, which is disposed on the outer surface of the housing 11. The trigger unit 14 issues a trigger signal by manually controlling the switch button.

 [0065] The control unit 15 is housed in the housing cavity of the housing 11. The control unit 15 receives the trigger signal from the trigger unit 14 and selects to switch the speaker 12. The control unit 15 is electrically coupled to the trigger unit 14. Specifically, in the present embodiment, the control unit 15 receives the trigger signal and compares it with the threshold according to the type of the trigger signal. When the value of the trigger signal reaches the threshold, the control unit 15 issues a control signal to turn on the speaker 12 corresponding to the side trigger unit 14 to turn on.

 [0066] Specifically, in the embodiment, the first speaker 121 and the second speaker 122 respectively correspond to a simulation switch 17 . The analog switch 17 controls the conduction of the first speaker 121 or the second speaker 122. When the human body approaches the copper foil located on the side of the casing 11, the capacitance of the capacitance formed by the human body and the copper foil changes. The control unit 15 outputs a control level signal to the analog switch 17 corresponding to the side speaker 12 according to the amount of change in the capacitance, and the analog switch 17 controls the corresponding first speaker 121 or second speaker 122 to turn on.

 [0067] It can be understood that the control unit 15 can be a micro control unit (MCU).

 [0068] For convenience of description, the structure of the earphone 10 provided by the present invention will be described in conjunction with a specific implementation process:

[0069] When the earphone 10 is worn on the right ear and the human body is close to the copper foil on the side where the first speaker 121 is located, the control unit 15 controls the analog switch 17 that controls the first speaker 121 to be turned on. Speaker 121. The side of the second speaker 122 is not activated because it is far away from the human body, so it does not work. The sound outlet 113 where the first speaker 121 is uttered is placed in the ear. When worn on the left ear, the human body is close to the copper foil on the side where the second speaker 122 is located, and the control unit 15 turns on the analog switch 17 that controls the second speaker 122 to activate the second speaker 122. Correspondingly, the side where the first speaker 121 is located is not operated because it is far from the human body, so it does not work. Therefore, the sound outlet 113 where the second speaker 122 of the working sound is located faces the ear.

 [0070] Moreover, the first speaker 121 and the second speaker 122 operate relatively independently. In the initial state, both the first speaker 12 1 and the second speaker 122 are turned off. When the sensing element 141 of the trigger unit 14 does not have capacitive sensing, the control unit 15 has no trigger signal input 吋, and the first speaker 121 and the second speaker 122 remain in the off state. When a capacitive sensing of the sensing element 141 on one side occurs, a trigger signal is issued. The control unit 15 inputs the trigger signal, activates the speaker corresponding to the side, and then continues to monitor the input of the side trigger signal until the side speaker is turned off without the trigger signal input.

 [0071] The earphone 10 can intelligently control the switching of the two-side speaker, assist the left and right ear to wear a fast switch, improve the user experience, and improve the brand value. Moreover, only the speaker on one side of the ear canal sounds, taking into account privacy.

 [0072] Moreover, the earphone 10 is a portable earphone 10, and the user can choose to wear the left ear or the right ear independently, thereby avoiding the feeling of pressure and discomfort caused by wearing the same ear for a long time, and improving user satisfaction.

 The above are only the preferred embodiments of the present invention, and are not intended to limit the scope of the present invention. The equivalent structural changes made by the description of the present invention and the accompanying drawings are included in the scope of the present invention.
