[0033] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0034] like Figure 2 As shown, a partial structural diagram of an audio device provided by an embodiment of the utility model, wherein the audio device may be headphones, speakers, electronic watches, electronic glasses, etc. When the audio device is a headset, it may be a headset, an in-ear headset, an ear-hook headset, or a neck-hook headset, etc., and the headset may be configured with a call noise reduction function and / or an artificial intelligence noise reduction function; at the same time, it may also be configured with stereo surround and other functions.

[0035] Combination Figure 2 and Figure 3 The audio device includes a housing 100 , a speaker 200 , an elastic supporting member 300 , a feedback microphone assembly 400 and a mainboard 500 .

[0036] The housing 100 is a hollow structure.

[0037] Combination Figure 2 and Figure 7, the speaker 200 is disposed within the housing 100, and the speaker 200 is provided with exposed connection terminals 210.

[0038] It can be understood that one end of the connection terminal 210 is electrically connected to the voice coil of the speaker 200, and the other end is in an exposed state; wherein, the connection terminal 210 being in an exposed state is with respect to the speaker 200, and the end of the connection terminal 210 away from the voice coil is exposed outside the speaker 200.

[0039] The elastic abutting member 300 is disposed inside the housing 100 and is spaced apart and oppositely disposed relative to the connection terminal 210.

[0040] Specifically, the elastic abutting member 300 is made of an elastic material, which can be a spring, elastic rubber, elastic sheet, etc. The elastic abutting member 300 is limited within the housing 100 and is spaced apart and oppositely disposed relative to the connection terminal 210.

[0041] It should be noted that the elastic abutting member 300 is made of an insulating material, or the surface of the elastic abutting member 300 is coated with an insulating layer, and the elastic abutting member 300 cannot conduct electricity.

[0042] Combined Figure 2 、 Figure 3 、 Figure 5 and Figure 6 , the feedback microphone assembly 400 is disposed inside the housing 100. The feedback microphone assembly 400 includes a feedback microphone 410 and a circuit board 420 electrically connected to the feedback microphone 410. The feedback microphone 410 is disposed in front of the speaker 200. The circuit board 420 passes through between the elastic abutting member 300 and the speaker 200 and abuts against and is electrically connected to the connection terminal 210 by the elastic force of the elastic abutting member 300.

[0043] It should be noted that the side where the diaphragm of the speaker 200 is located is the front side of the speaker 200, and the orientation of the diaphragm of the speaker 200 is the front of the speaker 200.

[0044] The main board 500 is disposed within the housing 100 and is electrically connected to the circuit board 420. The circuit board 420 is used to electrically connect the speaker 200 to the main board 500 and is also used to electrically connect the feedback microphone 410 to the main board 500.

[0045] It can be understood that there are at least two circuits integrated on the circuit board 420. One of the circuits is the first circuit 422, and the other circuit is the second circuit 423. The feedback microphone 410 is electrically connected to the main board 500 through the first circuit 422, and the speaker 200 is electrically connected to the main board 500 through the second circuit 423.

[0046] Specifically, the feedback microphone 410 is connected to the first circuit 422 on the circuit board 420. Under the elastic force of the elastic abutting member 300, the circuit board 420 abuts against the connection terminal 210 on the speaker 200, so that the speaker 200 is connected to the second circuit 423. In addition, the circuit board 420 is connected to the main board 500, thereby realizing the connection of the first circuit 422 and the second circuit 423 to the main board 500. In this way, under the action of the circuit board 420, the electrical connection between the speaker 200 and the main board 500 and the electrical connection between the feedback microphone 410 and the main board 500 can be realized.

[0047] As Figure 4 shown, it should be noted that the housing 100 is provided with a sound inlet hole 140 opposite to the feedback microphone 410, and the feedback microphone 410 can pick up sound signals through the sound inlet hole 140.

[0048] In the audio device of the present utility model, under the elastic force of the elastic abutting member 300, the circuit board 420 abuts against the connection terminal 210 on the speaker 200, thereby realizing the electrical connection between the speaker 200 and the circuit board 420. Moreover, under the action of the elastic abutting member 300, the reliable contact between the connection terminal 210 and the circuit board 420 is also realized, thereby reducing the risk of poor contact. And this connection method of relying on the elastic abutting member 300 to realize the connection between the connection terminal 210 and the circuit board 420 is simpler in operation and more conducive to improving the assembly efficiency compared with the method of welding the connection terminal and the circuit board, and can reduce environmental pollution.

[0049] As Figure 7 shown, in some embodiments, the connection terminal 210 is arranged on the side of the speaker 200, and the connection terminal 210 extends out from the side of the speaker 200. In this way, when the circuit board 420 extends to the side of the speaker 200, it can be in contact with the connection terminal 210; as Figure 1 shown, in the solution where the connection terminal 210 is arranged at the rear of the speaker 200, the circuit board 420 extends backward from the front of the speaker 200. After passing by the side of the speaker 200, it still needs to be bent to connect with the connection terminal 210. In this way, the required length of the circuit board 420 will become longer, resulting in an increase in cost.

[0050] Combined with Figure 2 and Figure 7 , further, the connection terminal 210 is arranged on the side of the speaker 200, and the elastic abutting member 300 can also be arranged on the side of the speaker 200 opposite to the connection terminal 210. Compared with the solution where the elastic abutting member 300 is arranged at the rear of the speaker 200, the elastic abutting member 300 will not hinder the disassembly and assembly of the speaker 200.

[0051] In some embodiments, the connection terminal 210 is a pogopin, and the pogopin abuts against the side of the circuit board 420 away from the elastic abutting member 300.

[0052] It can be understood that the pogopin applies a certain pressure to the circuit board 420, which can further improve the contact effect between the pogopin and the circuit board 420.

[0053] It should be noted that the pogopin is a conductive member. The pogopin is arranged on the bracket of the speaker 200, one end of the pogopin is connected to the voice coil, and the other end of the pogopin abuts against the side of the circuit board away from the elastic abutting member 300.

[0054] In other embodiments, the connection terminal 210 can also be a conductive post arranged on the speaker 200. Of course, in other embodiments, the connection terminal 210 can also be an exposed copper foil.

[0055] As Figure 5 shown, in some embodiments, a conductive portion 421 is arranged on the side of the circuit board 420 away from the elastic abutting member 300. The conductive portion 421 is a copper foil, and the connection terminal 210 abuts against the copper foil.

[0056] Specifically, the copper foil is connected to the second circuit 423 on the circuit board 420.

[0057] It should be noted that the copper foil can be formed on the circuit board 420 by a copper plating process.

[0058] Combined Figure 4 with Figure 6 , in some embodiments, a first installation groove 110 is arranged inside the housing 100. A second installation groove 120 is formed on the side wall of the first installation groove 110. The speaker 200 is arranged in the first installation groove 110 with the connection terminal 210 facing the second installation groove 120, and the elastic abutting member 300 is arranged in the second installation groove 120.

[0059] It can be understood that the first installation groove 110 is used to position the speaker 200, and the second installation groove 120 is used to position the elastic abutting member 300; by forming the second installation groove 120 on the side wall of the first installation groove 110 and arranging the elastic abutting member 300 in the second installation groove 120, the elastic abutting member 300 can be located on the side of the speaker 200, and the elastic abutting member 300 is opposite to the connection terminal 210 on the speaker 200. Moreover, the elastic abutting member 300 does not hinder the installation and disassembly of the speaker 200.

[0060] It should be noted that a sealing glue can be applied between the housing 100 and the speaker 200 to improve the sealing effect.

[0061] Further, a third installation groove 130 is formed on the bottom wall of the first installation groove 110. The front end of the speaker 200 faces the third installation groove 130, and the feedback microphone 410 is disposed in the third installation groove 130.

[0062] It can be understood that the third installation groove 130 is used to provide an installation space for the feedback microphone 410. In addition, a sound inlet hole 140 is opened on the bottom wall of the third installation groove 130.

[0063] In some embodiments, positioning posts 150 are provided on the bottom wall of the first installation groove 110, and the circuit board 420 is provided with positioning holes for the positioning posts 150 to pass through. In this way, the positioning accuracy of the circuit board 420 can be improved.

[0064] Further, the number of the positioning posts 150 can be multiple, the circuit board 420 is provided with multiple positioning holes, and the multiple positioning holes respectively allow the multiple positioning posts 150 to pass through.

[0065] Furthermore, a support portion 160 is provided on the bottom wall of the first installation groove 110, and the support portion 160 has a support surface for supporting the circuit board 420.

[0066] Specifically, the support surface is a flat surface, which is used to support the circuit board 420.

[0067] Specifically, the circuit board 420 is a flexible circuit board. By using the support portion 160 to support the circuit board 420, the risk of the circuit board 420 being wrinkled can be reduced.

[0068] In some embodiments, a rib 170 is formed on the bottom wall of the first installation groove 110. The rib 170 defines a limiting groove, and at least a part of the circuit board 420 is disposed in the limiting groove.

[0069] In the audio device of the present utility model, the feedback microphone 410 is electrically connected to the circuit board 420. Under the elastic force of the elastic abutting member 300, the circuit board 420 abuts against the connection terminal 210 on the speaker 200, so as to realize the electrical connection between the speaker 200 and the circuit board 420. Moreover, the circuit board 420 is also electrically connected to the main board 500. In this way, the circuit board 420 can electrically connect the speaker 200 to the main board 500, and can also electrically connect the feedback microphone 410 to the main board 500. In addition, under the action of the elastic abutting member 300, reliable contact between the connection terminal 210 and the circuit board 420 is also realized, thereby reducing the risk of poor contact. And this connection method of relying on the elastic abutting member 300 to connect the connection terminal 210 and the circuit board 420 is simpler in operation than the method of welding the connection terminal to the circuit board, which is beneficial to improving the assembly efficiency and can reduce environmental pollution.
