Abstract
The utility model discloses an acoustic module. The acoustic module comprises a loudspeaker monomer and a casing body which fixedly supports the loudspeaker monomer. A sound outlet channel which is used by the loudspeaker monomer to emit sounds is arranged in the casing body. The casing body comprises a first casing body and a second casing body. The first casing body and the second casing body are welded and fixed through ultrasonic. The casing body is provided with a first ultrasonic step and a second ultrasonic step. The first ultrasonic step and the second ultrasonic step are correspondingly arranged. The first ultrasonic step and the second ultrasonic step are arranged on the same side of the sound outlet channel. The acoustic module provided by the utility model has the advantages of simple assembly and high production yield.
Description
Technical field
The utility model relates to the electroacoustic field, and it is simple especially to relate to a kind of assembling, the acoustics module that the rate that manufactures a finished product 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 and rate of finished products also receive the concern of production firm.The acoustics module of traditional structure, adopt the mode of ultra-sonic welded that housing is welded, therefore, in two shells, be provided with a ultrasonic step, in the ultra-sonic welded process, a ultrasonic wave makes housing prolong ultrasonic step direction easily and produces skew, cause the shell welding to produce bad, improve assembly difficulty, reduced the rate of manufacturing a finished product.
Therefore, be necessary to propose a kind of improvement, to improve the deficiency of existing acoustic module.
The utility model content
It is simple that technical problem to be solved in the utility model provides a kind of assembling, the acoustics module that the rate that manufactures a finished product is high.
To achieve these goals, the utility model by the following technical solutions: a kind of acoustics module comprises the housing of loudspeaker monomer and the described loudspeaker monomer of fixed support; Be provided with sound channel in the described housing for the outgoing of described loudspeaker monomer sound, described housing comprises first housing and second housing, described first housing and second housing are fixed by ultrasonic bonding, and: described housing is provided with the first ultrasonic step and the second ultrasonic step, the described first ultrasonic step and the described second ultrasonic step are oppositely arranged, and the described first ultrasonic step and the described second ultrasonic step are arranged at described sound channel the same side.
As a kind of optimized technical scheme: described enclosure interior also is provided with the microphone monomer, and the corresponding described microphone monomer of described housing is provided with into sound channel.
As a kind of optimized technical scheme, described microphone monomer is electrically connected with external electronic circuits by same electrical connector with described loudspeaker monomer, and the corresponding described microphone monomer of described electrical connector is provided with different conductive electrodes with described loudspeaker monomer.
As further preferred, described electrical connector is a flexible PCB.
As a kind of optimized technical scheme: described sound channel is interior narrow outer wide horn type structure.
The utility model acoustics module, shell are provided with two ultrasonic steps that are oppositely arranged, and the power that produces in the time of can be with ultra-sonic welded is offset, avoid the shell skew, improve and produce yield, simplify assembly difficulty, therefore, it is simple that the utility model acoustics module has assembling, the advantage that the rate that manufactures a finished product is high.

Embodiment
Below in conjunction with accompanying drawing, describe the utility model acoustics module in detail.
The utility model acoustics module comprises the housing of loudspeaker monomer and the described loudspeaker monomer of support fixation, and housing is provided with the sound channel of corresponding loudspeaker monomer, and housing is fixed into one by first housing and second housing by ultrasonic bonding.
As depicted in figs. 1 and 2, second housing 12 is provided with the first ultrasonic step 21 and the second ultrasonic step 22, the first ultrasonic step 21 and the second ultrasonic step 22 are oppositely arranged, and as shown in Figure 1, the first ultrasonic step 21 and the second ultrasonic step 22 are arranged at sound channel 3 positions.As shown in Figure 3, first housing, 11 corresponding second housings, 12 ultrasonic step positions also are provided with ultrasonic step on the first ultrasonic step 21 and second ultrasonic step 22, the first housings 11 and second housing 12 through being ultrasonically welded to together.The first ultrasonic step 11 and second ultrasonic step 12 corresponding the settings, during ultra-sonic welded, the power that the power that the first ultrasonic step 21 produces and the second ultrasonic step 22 produce offsets, can avoid effectively that first housing, 11 relative second housings 12 are offset in the ultrasonic procedure, improve the production yield of acoustics module, reduce assembly difficulty.
As a kind of optimized technical scheme, the utility model acoustics module also includes the microphone monomer, the microphone monomer is arranged at enclosure interior, and by second housing, 12 support fixation, the microphone monomer adopts same electrical connector to be electrically connected with external electronic circuits with loudspeaker monomer, simplify circuit design, simplify assembly technology, improve the module integrated level, simultaneously, for the ease of assembling, electrical connector adopts flexible PCB.
As a kind of optimized technical scheme, as shown in Figure 1, sound channel 3 is interior narrow outer wide horn type structure, the first ultrasonic step 21 is greater than the second ultrasonic step 22, ultrasonic step on first housing 11 and second housing 12 cooperates, sound channel 3 is isolated with other cavitys of acoustics module, and the preceding operatic tunes of formation acoustics module has effectively utilized ultrasonic step; Simultaneously, horn type sound channel 3 can improve the acoustical behavior of speaking of acoustics module.
Be the utility model case study on implementation only below, be not limited to the utility model,, all should include in the protection range of putting down in writing in claims as long as the equivalence that those of ordinary skills do according to the utility model institute disclosure is modified or changed.
