Description
Technical field
The utility model relates to electro-acoustic product technical field, specifically, relates to a kind of loud speaker module.
Background technology
Existing loud speaker module, comprise loudspeaker monomer and the shell for holding loudspeaker monomer, be provided with module inner chamber in shell, loudspeaker monomer is arranged in module inner chamber, and whole module inner chamber is divided into the front operatic tunes and the rear operatic tunes two cavitys by loudspeaker monomer.The front operatic tunes is communicated with the external world by phonate hole, spreading out of for sound; The rear operatic tunes is the cavity of sealing.If the rear operatic tunes seals completely, the air pressure of loudspeaker monomer vibrating diaphragm both sides is different, affects loudspeaker monomer diaphragm oscillations, have an impact to the acoustical behavior of loud speaker module, meanwhile, the heat that loudspeaker monomer produces cannot distribute, rear sound cavity temperature raises, and causes voice coil loudspeaker voice coil broken string etc. bad.Therefore; in order to extend the useful life of loud speaker module and improve the acoustical behavior of loud speaker module; technical staff can be provided with a leak usually on module shell; leak can keep the exchange of air-flow inside and outside loud speaker module; the air pressure of balance module inner chamber, also plays the effect of heat radiation simultaneously.
Existing loud speaker module shell generally being offered a diameter is the leak of 0.6mm to 1.5mm, but leak easily causes loud speaker module, and low frequency energy significantly leaks, and makes loud speaker tonequality balanced not.Therefore, existing loud speaker module, the leak place on shell blocks up handicapping damping material and leaks to reduce loud speaker module low frequency energy.But loud speaker module pastes damping material complex process, and cost is high, and affects the outward appearance of loud speaker module.
Utility model content
Technical problem to be solved in the utility model is: provide a kind of loud speaker module, not be used in leak place and pastes damping material, thus reduce cost, improve production efficiency.
For solving the problems of the technologies described above, the technical solution of the utility model is:
A kind of loud speaker module, comprise loudspeaker monomer and the housing for holding described loudspeaker monomer, described housing comprises the first housing and the second housing, the cavity that described first housing and described second housing surround is divided into the front operatic tunes and the rear operatic tunes by described loudspeaker monomer, on described first housing or/and the position described second housing corresponding to the described rear operatic tunes is provided with several and leaks micropore, the described leakage microporous connectivity external world and the described rear operatic tunes, the diameter of described leakage micropore is 0.05mm to 0.15mm.
Preferably, the diameter of described leakage micropore is 0.1mm.
Preferably, described first housing is provided with the phonate hole for sound outgoing, the position of the corresponding described phonate hole in outside of described first housing is provided with Air Filter.
Preferably, described loudspeaker monomer to be just sticked flexible pad to the outer surface of described first housing.
Preferably, described cushion is foam cushion.
Preferably, on described second housing, the position of corresponding described loudspeaker monomer is provided with sheet metal, the operatic tunes before being formed between described second housing and described sheet metal.
Preferably, described sheet metal is steel disc.
Preferably, the thickness of described steel disc is 0.15mm.
After have employed technique scheme, the beneficial effects of the utility model are:
The housing of traditional loud speaker module is only provided with a larger leak, and the housing of loud speaker module of the present utility model, or/and the second housing is provided with several to leak micropore on the first housing, the diameter leaking micropore is 0.05mm to 0.15mm.First housing of loud speaker module of the present utility model is or/and much less than the diameter of the leak on the housing of traditional loud speaker module of the diameter of leakage micropore on the second housing, thus while making the air pressure of leakage micropore before and after balance in the operatic tunes, can effectively prevent the low frequency energy in loud speaker module from leaking.Thus make loud speaker module of the present utility model not need to paste damping material again at leakage micropore place, prevent low frequency energy from leaking.Thus make the manufacturing procedure decreasing loud speaker module, reduce material cost and cost of labor, improve production efficiency.
Because described loudspeaker monomer to be just sticked flexible pad to the outer surface of described first housing.The first housing and the second housing are carried out ultrasonic bonding with make the first housing and the second housing effectively in conjunction with time, cushion can cushion loudspeaker monomer, avoid loudspeaker monomer impaired, and, cushion can regulate the acoustical behavior of loud speaker module, improves loud speaker module acoustical behavior.
Because the position of described loudspeaker monomer corresponding on the second housing is provided with sheet metal.Because metal material just can ensure mechanical strength under relatively low thickness, such as steel disc can reach desirable strength when its thickness is about 0.2mm, like this when the second housing adopts relatively little thickness in conjunction with sheet metal, just can reach the intensity that the second housing needs.Thus the integral thickness of product can be reduced, be conducive to the slimming realizing producing sheet.
