Description

Technical Field

[0001] This application relates to the field of audio technology, and more specifically, to a speaker assembly and an audio. Background Art

[0002] Structures such as speakers and circuit boards form a speaker assembly. In existing speaker assemblies, the positive and negative electrodes of the speaker are usually connected to the circuit board by two wires. During the connection process, the speaker and the circuit board may be parallel or intersect. The parallelism between the speaker and the circuit board should be understood as the plane where the sound outlet of the speaker is located is parallel to the conductive layer on the circuit board. When the speaker and the circuit board are parallel, the connection structure between them is simple. However, when the speaker and the circuit board intersect, in order to avoid internal components or ensure that the speaker does not become loose, a more complex installation method is required.

[0003] In order to achieve the assembly of the speaker and the circuit board in the case where the speaker and the circuit board intersect, the prior art usually installs a metal clip on the conductive layer of the circuit board and clamps the terminals extending from the speaker through the metal clip, or welds the terminals of the speaker to the circuit board by soldering wires, or abuts the terminals of the speaker against the conductive layer of the circuit board in the form of a spring piece. However, the above connection methods between the speaker and the circuit board all have the disadvantages of complex connection structure and long assembly time. For example, the metal clip is prone to insufficient clamping force and difficult alignment with the terminals; moreover, when the speaker works at high power, in the above two connection methods of clamping the speaker terminals with a metal clip or connecting the speaker terminals to the circuit board in the form of a spring piece, there will be vibration friction between the speaker terminals and the circuit board, resulting in wear, shedding and oxidation of the surfaces of the terminals and the conductive layer, thereby reducing the output power and service life of the speaker; finally, the above two connection methods of clamping the speaker terminals with a metal clip or connecting the speaker terminals to the circuit board in the form of a spring piece both have the problem of generating resonance noise after vibration, affecting the quality of the speaker.

[0004] In summary, the assembly formed by the speaker and the circuit board in the prior art has problems such as high assembly cost, low assembly efficiency, short service life, and poor sound quality. Summary of the Utility Model

Detailed implementation

[0033] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the technical field to which this application belongs; the terms used in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application; the terms "including" and "having" and any variations thereof in the specification and claims of this application and the above drawings are intended to cover non-exclusive inclusion.

[0034] Reference herein to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of this application. The phrase appears in various places in the specification and does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive of other embodiments. Those skilled in the art will explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments. Figure 2 In the Z direction is the up and down direction, the X direction is the front and back direction, and the Y direction is the left and right direction.

[0035] Please refer to Figures 1 to 3 , to solve the above technical problems, the technical solution of the present utility model provides a speaker assembly 10, the speaker assembly 10 includes a speaker 300, a circuit board 100, at least two terminals 200 and at least two connecting members 20, a conductive layer (not marked in the figure) is provided on the surface of the circuit board 100 facing the speaker 300, one end of the terminal 200 abuts against the conductive layer, and the other end is connected to the speaker body 310, and the connecting members 20 are respectively passed through the conductive layer and the terminal 200 to connect the terminal 200, the conductive layer and the speaker 300.

[0036] In this embodiment, the connecting member 20 passes through both the conductive layer and the terminal 200 at the same time, thereby fixing the terminal 200 abutting against the conductive layer and the conductive layer. At this time, the terminal 200 serves the function of electrical connection and also serves to fix the speaker 300 and the circuit board 100; compared with the prior art solution of welding to connect the speaker 300 and the circuit board 100, there is no need for welding between the speaker 300 and the circuit board 100 in this embodiment. Therefore, the assembly cost of the speaker 300 is low. Compared with the prior art in which a metal clip clamps the terminal 200 of the speaker 300 or the terminal 200 of the speaker 300 is in the form of a shrapnel, the terminal 200 in this embodiment is directly attached to the conductive layer and is fixed by the connecting member 20 passing through it. Therefore, under the fixing action of the connecting member 20, the terminal 200 is not likely to vibrate and slip, and there is no need to perform the alignment process of the metal clip. Furthermore, it can avoid the reduction of the service life caused by wear between the terminal 200 and the conductive layer, avoid generating noise, and improve the assembly efficiency.

[0037] In summary, the speaker assembly 10 of the present application can improve the assembly efficiency between the speaker 300 and the circuit board 100, reduce the assembly cost, increase the service life, and avoid generating noise.

[0038] Further, please refer to Figures 1 to 3 , an installation protrusion 213 is formed on the terminal 200 in a direction away from the conductive layer. The bottom of the installation protrusion 213 abuts against the conductive layer. The installation protrusion 213 is provided with an installation hole 211. The connecting member 20 passes through the installation hole 211 and is threadedly connected to the installation hole 211.

[0039] In this embodiment, the installation protrusion 213 can increase the contact area between the connecting member 20 and the terminal 200, thereby improving the connection stability between the terminal 200 and the circuit board 100; the threaded connection between the connecting member 20 and the installation hole 211 can further prevent the terminal 200 from vibrating relative to the conductive layer. At the same time, the threaded connection method enables the installation and disassembly efficiency of the connecting member 20 to be relatively high. In summary, the speaker assembly 10 of this embodiment has strong stability and high assembly efficiency.

[0040] Further, please refer to Figures 1 to 3 , the speaker 300 includes a sound outlet 311. The terminal 200 includes a first connecting portion 210 and a second connecting portion 220 that are connected to each other. The first connecting portion 210 is parallel to the conductive layer, and the second connecting portion 220 is parallel to the sound outlet 311;

[0041] wherein, the conductive layer and the sound outlet 311 intersect.

[0042] If the circuit board 100 is parallel to the sound outlet 311, in order to avoid blocking the sound, the circuit board 100 needs to be placed on the side of the speaker 300 where the sound outlet 311 is not provided, that is, the thickness of the sound box will increase, resulting in an increase in the floor area occupied by the speaker assembly 10.

[0043] In this embodiment, the intersection of the sound outlet 311 and the conductive layer should be understood as the intersection of the plane where the sound outlet 311 is located and the conductive layer. Since the conductive layer intersects the sound outlet 311, the speaker 300 and the circuit board 100 intersect. Therefore, the speaker 300 and the circuit board 100 can be arranged in the up and down direction, thereby avoiding an increase in the floor area occupied by the speaker assembly 10. On the other hand, when the circuit board 100 intersects the speaker 300 and the circuit board 100 is fixed inside the sound box, the speaker 300 is connected to the circuit board 100 through the terminal 200. At this time, the circuit board 100 plays a role in suspending the speaker 300 to a certain extent, thereby fixing the speaker 300. It can be understood that the conductive layer and the sound outlet 311 can be perpendicular.

[0044] Further, please refer to Figures 1 to 3 , the second connecting portion 220 is an elastic member, and at least a part of the second connecting portion 220 is bent to form an avoidance gap 221.

[0045] In this embodiment, since at least a part of the second connecting portion 220 is bent to form an avoidance gap 221, at this time, if the speaker 300 or the second connecting portion 220 vibrates due to an external force, the force in the up and down direction between the two will be weakened through the avoidance gap 221, that is, the avoidance gap 221 becomes smaller through the gap, thereby forming the use of its own elastic deformation to link the up and down vibration between the speaker 300 and the circuit board 100, and further reducing the amplitude of vibration of the first connecting portion 210 after being stressed. At the same time, when connecting the terminal 200 and the speaker 300, the deformable avoidance gap 221 enables the terminal 200 to adjust its position in the up and down direction, so that it is located at a position suitable for connecting the speaker 300, improving the assembly efficiency of the speaker assembly 10.

[0046] It should be understood that the avoidance gap 221 should be higher than the connection part of the second connecting portion 220 and the speaker 300 in the up and down direction, that is, the avoidance gap 221 is between the connection part of the second connecting portion 220 and the speaker 300 and the first connecting portion 210.

[0047] Further, please refer to Figures 1 to 3 , the speaker assembly 10 further includes an insulating member 400, the insulating member 400 is connected to one end of the second connecting portion 220, and the first connecting portion 210 is connected to the other end of the second connecting portion 220;

[0048] The speaker 300 includes a speaker main body 310, a bracket 320, and a wire (not shown in the figure). The speaker main body 310 is connected to the bracket 320 of the speaker 300, and an insulating member 400 is connected to the bracket 320 of the speaker 300. One end of the wire is connected to the speaker main body 310, and the other end is connected to the second connection portion 220.

[0049] In this embodiment, the speaker main body 310 is fixed to an external device by the bracket 320. At this time, if the terminal 200 is connected to the speaker main body 310, it is difficult to disassemble and replace the speaker main body 310. Therefore, the second connection portion 220 of this embodiment is connected to the insulating member 400, and then the insulating member 400 is connected to the bracket 320 instead of the speaker main body 310, thereby enabling the speaker main body 310 to be quickly replaced and repaired. At the same time, because the insulating member 400 has insulating properties, it can avoid electrical connection between the bracket 320 and the conductive layer, thereby reducing the sound power of the speaker main body 310.

[0050] Furthermore, please refer to Figures 1 to 3 , the second connection portion 220 is provided with a first connection protrusion 222, the first connection protrusion 222 is provided with a first through hole 223, the insulating member 400 is provided with a first connection hole, the first connection protrusion 222 is inserted into the first connection hole, and an insulating layer is provided on the inner wall of the first through hole 223;

[0051] One end of the wire facing the speaker main body 310 passes through the first through hole 223 and is connected to the end of the first connection protrusion 222 away from the speaker 300.

[0052] In this embodiment, the speaker main body 310 and the second connection portion 220 are connected by a wire. Since the wire passes through the first through hole 223 and is connected to the end of the first connection protrusion 222 away from the speaker 300, when the speaker 300 and the circuit board 100 move left and right, the wire will play a certain fixing role, thereby preventing the speaker 300 and the circuit board 100 from being misaligned.

[0053] Furthermore, please refer to Figures 1 to 3 , the first connection protrusion 222 is provided on the side of the second connection portion 220 away from the speaker main body 310. A second connection protrusion 410 is provided on the side of the insulating member 400 facing the speaker main body 310, and the bracket 320 is provided with a second connection hole 321. The second connection protrusion 410 is inserted into the second connection hole 321.

[0054] In this embodiment, the protruding directions of the first connecting protrusion 222 and the second connecting protrusion 410 are opposite, and they are respectively arranged on the insulating member 400 and the second connecting portion 220. Therefore, when there is a tensile force in the up-and-down direction between the circuit board 100 and the speaker 300, the objects subjected to the shear force will be between the first connecting protrusion 222 and the second connecting portion 220, and between the second connecting protrusion 410 and the insulating member 400 respectively. Therefore, compared with the technical solution in which both the first connecting protrusion 222 and the second connecting protrusion 410 are present on the second connecting portion 220, the second connecting portion 220 in this embodiment is less likely to be bent and broken because it is subjected to less shear force.

[0055] Further, please refer to Figures 1 to 3 , the second connecting portion 220 can be bent to form a plurality of avoiding gaps 221.

[0056] In this embodiment, the plurality of avoiding gaps 221 can increase the ability of the second connecting portion 220 to absorb vibration force during deformation when a force in the up-and-down direction is applied, thereby enhancing the vibration damping performance of the terminal 200, the structural strength and installation efficiency of the speaker assembly 10.

[0057] Further, please refer to Figures 1 to 3 , the speaker assembly 10 further includes an elastic gasket (not shown in the figure), the connecting member 20 is a screw, the head of the screw and the conductive layer are respectively located on both sides of the circuit board 100, and the elastic gasket is arranged between the head of the screw and the circuit board 100.

[0058] In this embodiment, the elastic gasket can improve the connection stability between the screw and the circuit board 100 and the terminal 200 by applying a pre-tightening force.

[0059] Further, please refer to Figures 1 to 3 , at least two terminals 200 are connected to one speaker 300, and one terminal 200 is connected to the positive electrode of the speaker 300, and the other terminal 200 is connected to the negative electrode of the speaker 300.

[0060] In this embodiment, the terminal 200 connected to the positive electrode of the speaker 300 is the positive terminal 200, and the terminal 200 connected to the negative electrode of the speaker 300 is the negative terminal 200.

[0061] Further, please refer to Figures 1 to 3 , there can be a plurality of speakers 300 and terminals 200, and one speaker 300 corresponds to two terminals 200.

[0062] In this embodiment, when there are a plurality of speakers 300 and terminals 200, the arrangement direction of the terminals 200 can be arranged in the front-back direction in the figure. At this time, the speakers 300 are also arranged in the front-back reverse direction, so that a plurality of speakers 300 are connected to one circuit board 100.

[0063] Correspondingly, the present application provides an audio device. Please refer to Figures 1 to 3 , the audio device includes the speaker assembly 10 of any one of the above embodiments.

[0064] In this embodiment, the connecting member 20 passes through the conductive layer and the terminal 200 at the same time, thereby fixing the terminal 200 abutting against the conductive layer and the conductive layer. At this time, the terminal 200 plays a role of electrical connection and also plays a role of fixing the speaker 300 and the circuit board 100; at the same time, under the fixing action of the connecting member 20, the terminal 200 is not likely to vibrate and slip off, and there is no need to perform the alignment process of the metal clip, thereby being able to avoid the reduction of the service life caused by wear between the terminal 200 and the conductive layer, avoid the generation of noise in the audio device, and improve the assembly efficiency of the audio device.
