Description

The acoustics module

Technical field

The utility model relates to the electroacoustic field, and it is simple especially to relate to a kind of technology, the acoustics module that reliability is high.

Background technology

Expansion along with consumer electronics market, consumer electronics products such as a large amount of mobile phones, notebook computer are used widely, people are also more and more higher to the requirement of consumer electronics product, people also more and more pay attention to other fields such as outward appearance, acoustical behavior in the function of paying attention to consumer electronics product.

In the face of the development trend of consumer electronics product miniaturization, microminiaturization, people are to the acoustic module miniaturization, and modular requirement is also more and more higher, and simultaneously, in order to improve the market competitiveness, the production efficiency of acoustic module also receives the concern of production firm.The acoustics module of traditional structure is electrically connected module and external electronic circuits by circuit board, and circuit board gets on to expect that by housing the hole that forms extends module, complex manufacturing.

Therefore, be necessary to propose a kind of improvement, to improve the deficiency of existing acoustic module.

The utility model content

Technical problem to be solved in the utility model is that a kind of technology of proposition is simple, the acoustics module that reliability is high.

To achieve these goals, the utility model is by the following technical solutions:

A kind of acoustics module comprises the housing of loudspeaker monomer, the described loudspeaker monomer of fixed support and the flexible PCB that is electrically connected described acoustics module and external electronic circuits; Described flexible PCB extends described housing; Described housing comprises first housing and second housing, and described loudspeaker monomer is fixed in described second housing, and described flexible PCB is fixed in described second housing; And: the corresponding described flexible PCB of described second housing extends described shell position and is provided with locating notch, and described locating notch cooperates the formation flexible PCB to extend the elongated hole of described housing with described first housing.

As a kind of optimized technical scheme, described acoustics module also comprises the microphone monomer, and described microphone monomer is accommodated and is fixed in described enclosure interior, and described microphone monomer is electrically connected with described flexible PCB.

As a kind of optimized technical scheme, described flexible PCB is fixed by mode and described second housing of buckle.

As a kind of optimized technical scheme, described flexible PCB extends described housing parts and bends along the described second housing breach, and the bending of described flexible PCB extension is fixed in described second housing away from described first housing, one side.

Acoustics module of the present utility model, derive flexible PCB by the locating notch on second housing, make things convenient for the assembling of module flexible PCB, simplify the module production technology, simultaneously, the second housing locating notch cooperates with first housing, and flexible PCB is positioned, guarantee flexible PCB fixation degree, improve module reliability; Therefore, it is simple that the utility model acoustics module has technology, the advantage that reliability is high.

Embodiment

Below, by reference to the accompanying drawings, describe the utility model acoustics module in detail.

As shown in figures 1 and 3, the utility model acoustics module comprises the housing of being made up of first housing, 11, the second housings 12 and the 3rd housing 13, second housing, 12 inside arrange fixedly loudspeaker monomer 31, and loudspeaker monomer 31 is electrically connected with external circuit by flexible PCB 2.As Fig. 1, Fig. 2 and shown in Figure 3, the position that the corresponding flexible PCB 2 of second housing extends housing is provided with locating notch 121, flexible PCB 2 is by locating notch 121, reduce the assembly difficulty of flexible PCB 2, simplified assembly technology, simultaneously, locating notch 121 cooperates fixing flexible circuit board 2 with first housing 11, improves flexible PCB 2 fixation degree.During the assembling of the utility model acoustics module, flexible PCB 2 is assemblied on second housing 12, directly extend housing by locating notch 121, second housing 12 and first housing 11 are fixing, locating notch 121 cooperates the formation elongated hole with first housing 11, needn't design elongated hole at second housing 12.The utility model acoustics module, flexible PCB 2 directly assembles, and needn't extend housing by the elongated hole of special setting, has simplified assembly technology, simultaneously locating notch 121 cooperates effectively with first housing 11 and flexible PCB 2 is positioned the raising module reliability.

As shown in Figure 3, the utility model acoustics module also is provided with microphone monomer 32, and microphone monomer 32 is accommodated and is fixed in enclosure interior, and microphone monomer 32 also is electrically connected with flexible PCB 2.The utility model acoustics module has been wholely set loudspeaker monomer 31 and microphone monomer 32, has improved the integrated level of module, is conducive to the miniaturization design of module.

As shown in Figure 3, flexible PCB 2 is fixed in second housing, 12 inside by the mode of buckle, the flexible PCB 2 of snap fit can avoid effectively that to reduce the flexible PCB 2 cause fixing insecure owing to the module height, further improves the reliability of acoustics module.

As depicted in figs. 1 and 2, flexible PCB 2 extends the part of housing and extends the back bending at locating notch 121, be fixed in second housing 12 away from first housing, 11 1 sides after the bending of flexible PCB 2 extensions, can reduce acoustics module area, improve the module space availability ratio.

Be the utility model case study on implementation only below, be not limited to the utility model, as long as the equivalence that those of ordinary skills do according to the utility model institute disclosure is modified or changed, all should include in the protection range of putting down in writing in claims.
