For reducing the through hole of fair line trench bottom to the impact of microphone acoustic performance, prior art, generally after fair line, uses the through hole of fluid sealant shutoff fair line trench bottom.And adopt the operation of fluid sealant shutoff fair line groove can increase operation intensity, affect operating efficiency, and production cost can be increased.

Utility model content

In view of the above problems, the utility model provides a kind of microphone module, to solve in prior art the increase operation intensity adopting the operation of fluid sealant shutoff fair line groove to cause, the problem affecting operating efficiency, increase production cost.

For achieving the above object, the technical solution of the utility model is achieved in that

The utility model provides a kind of microphone module, and microphone module internal is provided with microphone monomer 5 and corresponding fair line groove 2; Fair line groove 2 is one-body molded with microphone module main body 1, and comprise a diapire 21 and at least two sidewalls 22,23, microphone module main body 1 forms the diapire 21 of fair line groove 2.

Preferably, at least one sidewall 22 or 23 of fair line groove 2 is designed with pressuring line structure 3, pressuring line structure 3 is for being secured across the wire rod 4 of fair line groove 2.

Preferably, a sidewall 22 of fair line groove 2 is designed with pressuring line structure 3, relative pressuring line structure 3 place of another sidewall 23 of fair line groove 2 is designed with and dodges space 24.

Preferably, two sidewalls 22,23 of fair line groove 2 are designed with the pressuring line structure 3 mutually staggered respectively.

Preferably, pressuring line structure 3 is the projection perpendicular to diapire 21.

Preferably, wire rod 4 connects the wiring board PCBA7 of microphone monomer 5 and microphone module main body 1.

The beneficial effect of the utility model embodiment is: the fair line groove in the utility model microphone module comprises a diapire and at least two sidewalls, fair line groove and microphone module main body one-body molded time, by the diapire making microphone module main body form fair line groove, overcoming fair line trench bottom in prior art is the defect of through hole, and the noise avoiding the noise sources such as the fan of microphone module internal to produce enters microphone monomer; And compared to prior art, the present embodiment eliminates the operation of fluid sealant shutoff fair line groove bottom wall, can reduce the use of material, thus reduce production cost, enhance productivity.

Embodiment

For making the purpose of this utility model, technical scheme and advantage clearly, below in conjunction with accompanying drawing, the utility model execution mode is described in further detail.

The generalized section of fair line groove in the microphone module that Fig. 2 provides for the present embodiment, the perspective view of the microphone module internal that Fig. 3 provides for the present embodiment, Fig. 4 is the partial structurtes enlarged drawing of Fig. 3.

As Fig. 2 ~ Fig. 4 jointly shown in, the microphone module in Fig. 2, is provided with microphone monomer 5 and corresponding fair line groove 2 in microphone module internal; Fair line groove 2 is one-body molded with microphone module main body 1, and fair line groove 2 comprises a diapire 21 and at least two sidewalls 22,23, and microphone module main body 1 forms the diapire 21 of fair line groove 2.

The present embodiment adopts novel making mould, enable fair line groove and microphone module main body one-body molded, and fair line groove bottom wall is microphone module main body.Because the fair line trench bottom of the present embodiment is without through hole, the noise that the noise sources such as fan 6 produce can not enter microphone monomer, and therefore, the microphone module of the present embodiment can avoid the impact of noise on microphone property of module internal effectively; And relative to prior art, the present embodiment, without the need to carrying out the operation adopting fluid sealant shutoff fair line groove, therefore, can also be saved material, reduce production cost, enhance productivity.
