Technical Field
[0001] The utility model relates to the technical field of electronic products, in particular to a microphone assembly structure for a sound box. Background Art
[0002] Sound box products are common electronic products. The adverse impact caused by vibration on the acoustic effect of the sound box has always been a thorny problem faced by the sound box industry. How to effectively reduce the impact of vibration is one of the key research directions that the industry has been working hard to solve. In the traditional sound box structure design, the microphone component (i.e., the microphone assembly) and the speaker are generally directly fixed on the housing of the main body. The vibration of the speaker will drive the housing to vibrate. And the microphone component is directly fixed on the housing, and the vibration generated by the housing will be transmitted to the microphone component, resulting in the microphone component also vibrating, and then causing distortion of the microphone. Content of the Utility Model
[0003] Aiming at the defects existing in the prior art, the utility model provides a microphone suspension assembly structure for a sound box, which can isolate the vibration of the housing from the microphone component through a simple structure design, thereby reducing the vibration of the microphone and reducing the distortion of the microphone.
[0004] To solve the above technical problems, the utility model adopts the following technical scheme: A microphone suspension assembly structure for a sound box, including a housing and a microphone component. The microphone component is installed on the housing through a cover plate. It is characterized in that: It also includes an elastic member made of soft rubber. A sound pickup hole is provided in the elastic member. The microphone component is installed on the bottom surface of the elastic member and is opposite to the sound pickup hole; A sponge is provided on the housing, and the bottom of the microphone component is padded on the sponge; An installation hole is provided on the cover plate, and the elastic member is embedded in the installation hole and fixed on the sponge through the cover plate, so that the microphone component forms a suspended assembly structure relative to the housing.
[0005] Further, a fixing portion is provided in the central region of the elastic member. The bottom surface of the fixing portion is recessed inward to form a fixing groove. The microphone component is installed in the fixing groove, and the sound pickup hole is provided on the fixing portion.
[0006] Further, a ring of elastic ring is provided between the edge of the elastic member and the fixing portion. The thickness of the elastic ring is smaller than the thickness of the edge and the fixing portion of the elastic member, so that the elasticity of the elastic ring is greater than other parts of the elastic member.
[0007] Further, the elastic ring is an arc-shaped concave structure, and the fixing portion and the edge of the elastic member are connected as a whole through the elastic ring.
[0008] Further, fixing ears are provided on the edge of the elastic member, and fixing columns are provided on the cover plate at positions corresponding to the fixing ears. The elastic member is positioned by passing the fixing columns through the fixing ears.
[0009] Furthermore, a gasket is provided at the edge position around the elastic member, and the cover plate presses on the gasket to press the elastic member tightly on the sponge.
[0010] Preferably, the elastic member is made of silica gel. Of course, other soft rubbers such as TPR can also be used.
[0011] Furthermore, a set of microphone assemblies with elastic members are respectively provided at positions close to both sides of the housing, and an auxiliary microphone group is provided on the housing between the two sets of microphone assemblies. The auxiliary microphone group includes six auxiliary microphones.
[0012] In the utility model, the microphone assembly is assembled by arranging an elastic body on the housing, and a sponge is used to isolate the bottom of the microphone assembly from the housing. In this way, the vibration of the housing can be isolated to the greatest extent, thereby reducing the vibration of the microphone assembly and further reducing the distortion of the microphone.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0022] In this embodiment, refer to Figures 1 - 5, the microphone suspension assembly structure applied to the sound box includes a housing 1, a speaker, and a microphone assembly 4. The microphone assembly 4 is installed on the housing 1 through a cover plate 2. It also includes an elastic member 3 made of soft rubber. A sound pickup hole 33 is provided in the elastic member 3. The microphone assembly 4 is installed on the bottom surface of the elastic member 3 and is opposite to the sound pickup hole 33, and the external sound is collected through the sound pickup hole 33. A sponge 5 is provided on the housing 1, and the bottom of the microphone assembly 4 is placed on the sponge 5. An installation hole 21 is provided on the cover plate. The elastic member 3 is embedded in the installation hole 21 and fixed to the sponge 5 through the cover plate 2, so that the microphone assembly 4 forms a suspended assembly structure relative to the housing 1, that is, there is no hard connection between the microphone assembly 4 and the housing 1.
[0023] A fixing portion 31 is provided in the central region of the elastic member 3. The bottom surface of the fixing portion 31 is recessed inward to form a fixing groove 32. The microphone assembly 4 is installed in the fixing groove 32, and the sound pickup hole 33 is provided on the fixing portion 31.
[0024] A circular elastic ring 34 is provided between the edge of the elastic member 3 and the fixing portion 31. The thickness of the elastic ring 34 is smaller than the thickness of the edge and the fixing portion 31 of the elastic member 3, so that the elasticity of the elastic ring 34 is greater than that of other parts of the elastic member 3, which can maintain good elasticity under the condition of stable assembly.
[0025] The elastic ring 34 has an arc-shaped concave structure, similar to the remaining part after cutting off a part of a circular tube along the ring. The fixing portion 31 and the edge of the elastic member 3 are connected as a whole through the elastic ring 34.
[0026] Fixing ears 35 are provided at the edge of the elastic member 34. Fixing columns 22 are provided at the positions corresponding to the fixing ears 35 on the cover plate 2. The elastic member 3 is positioned by passing the fixing columns 22 through the fixing ears 35.
[0027] A gasket 6 is provided around the edge of the elastic member 3. The cover plate 2 presses on the gasket 6 to press the elastic member 3 tightly on the sponge 5, making the stability of the fixed elastic member 3 higher.
[0028] The elastic member 3 is made of silica gel. Of course, other soft rubbers such as TPR can also be used.
[0029] A set of microphone assemblies 4 with elastic members 3 are provided at positions near both sides of the housing 1. An auxiliary microphone group 7 is provided on the housing 1 between the two sets of microphone assemblies 4. The auxiliary microphone group 7 includes six auxiliary microphones. The 8 microphones are symmetric left and right. By using the strength of the sounds received by different microphones, different sounds such as games, players, and environments can be accurately identified through algorithms, and only the player's voice is retained, enabling players to clearly communicate tactics in the game. The frequency response curve in this case can be referred to Figure 6, which indicates that when the volume output is different, the frequency response curve is overly smooth and the sound is not compressed.
[0030] Refer to Figure 7 This is the harmonic distortion graph of the present utility model, which shows that the suspension design of the microphone assembly 4 makes the distortion performance of each microphone consistent.
[0031] Refer to Figure 8 This is the comparison graph of the harmonic distortion of the present utility model and the harmonic distortion of the traditional cavity hard connection. Among them, the blue represents the installation structure of the traditional microphone, that is, the microphone adopts a hard connection structure without a suspension structure. The green represents that the microphone of the present utility model adopts a soft connection and has a suspension structure.
[0032] By comparing the two curves, it can be seen that when the microphone adopts a suspension design, the distortion of the microphone receiving signal is also greatly reduced during the game, enabling players to have clear conversations during the game and effectively reducing the distortion of the microphone.
[0033] The present utility model has been described in detail above. The above description is only the preferred embodiment of the present utility model, and it cannot limit the scope of implementation of the present utility model. That is, all equal changes and modifications made according to the scope of this application should still fall within the scope covered by the present utility model.
