Description
Technical field
The present invention relates to electro-acoustic product technical field, particularly a kind of loud speaker module packaging technical.
Background technology
Loud speaker module is the important acoustic element of portable electric appts, for completing the conversion between the signal of telecommunication and voice signal, is a kind of energy conversion device.Existing loud speaker module generally includes shell, loudspeaker monomer is contained in shell, whole module inner chamber is separated into the front operatic tunes and the rear operatic tunes two cavitys by loudspeaker monomer, the size of the rear operatic tunes decides the medium and low frequency tonequality of loud speaker module, the rear operatic tunes is larger, and the medium and low frequency tonequality of loud speaker module is better.
At present, continuous to frivolous, small and exquisite future development along with portable electric appts, the loud speaker module as its important acoustic element also needs to frivolous, small and exquisite future development, thus causes the rear operatic tunes volume of loud speaker module constantly to be compressed.In the ever-reduced situation of rear operatic tunes volume, enough low in order to ensure the resonance frequency of loud speaker module, to ensure the medium and low frequency tonequality of loud speaker module, technical staff is bonding porous sound-absorbing material on rear operatic tunes inwall, to the quick absorption of gas and release action, rear operatic tunes space virtual is increased by sound-absorbing material, thus reduce the resonance frequency of loud speaker module.
But, there is many volatile organic solvents in bonding agent, and bonding agent can produce organic molecule in the process of solidification.In bonding process, volatile materials is easily adsorbed by porous sound-absorbing material, thus blocks the duct of sound-absorbing material, makes sound-absorbing material weaken the absorption of gas and desorption ability or disappear, thus cannot reach the effect reducing loud speaker module resonance frequency.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of loud speaker module packaging technical, the volatile substance adsorption that this loud speaker module packaging technical can effectively prevent bonding agent from producing is on sound-absorbing material, ensure that sound-absorbing material is to the absorption of gas and desorption ability, thus improve the acoustical behavior of loud speaker module.
For solving the problems of the technologies described above, technical scheme of the present invention is:
A kind of loud speaker module packaging technical, comprises the steps: to be fixed to by loudspeaker monomer in the shell of described loud speaker module, makes the inner chamber of described loud speaker module be divided into the front operatic tunes and the rear operatic tunes two cavitys by described loudspeaker monomer; In the described rear operatic tunes, filling sound-absorbing material, in the described rear operatic tunes, being provided with the isolated part for isolating described loudspeaker monomer and described sound-absorbing material; Seal the described rear operatic tunes; Also be included in the step to filling with inert gas in described rear operatic tunes when filling described sound-absorbing material to the described rear operatic tunes.
Wherein, the step purging described inert gas to described rear operatic tunes position to carrying out before the described rear operatic tunes fills described sound-absorbing material is also included in.
Wherein, described shell is made up of at least two housings combined, the step purging described inert gas to a described rear operatic tunes position described housing wherein not with housing described in other in conjunction with time carry out.
Wherein, after each described housing combines, housing described in one of them is provided with filling aperture to the position in requisition for the described rear operatic tunes position of filling described sound-absorbing material, and described sound-absorbing material is filled in the described rear operatic tunes from described filling aperture; After described sound-absorbing material end-of-fill, at the described rear operatic tunes of outer side covers seal sealing of described filling aperture.
Wherein, the described inert gas filled in the described rear operatic tunes when filling described sound-absorbing material to the described rear operatic tunes is filled with in the described rear operatic tunes by described filling aperture.
As a kind of execution mode, be first evacuated in the described rear operatic tunes before being filled with described inert gas by described filling aperture in the described rear operatic tunes, then fill with quantitative described inert gas in the described rear operatic tunes.
As another execution mode, continue to be filled with described inert gas in the described rear operatic tunes by described filling aperture, until described sound-absorbing material is filled complete.
Wherein, described shell comprises the upper casing, mesochite and the lower casing that combine successively, and described loudspeaker monomer, described upper casing, described mesochite and described lower casing surround the described rear operatic tunes jointly, and described isolated part is arranged between described mesochite and described lower casing; The step purging inert gas to described rear operatic tunes position described lower casing not with described mesochite in conjunction with time carry out.
Wherein, described filling aperture is arranged on described lower casing.
Wherein, described inert gas is the one in nitrogen, argon gas, helium or neon.
After have employed technique scheme, the invention has the beneficial effects as follows:
Due to loud speaker module packaging technical of the present invention filling with inert gas in the operatic tunes backward when the operatic tunes backward fills sound-absorbing material; inert gas is a kind of monoatomic gas of colorless and odorless at normal temperatures; highly stable, be difficult to carry out chemical reaction, through being often used as protection gas.Therefore, inert gas is filled with while the operatic tunes backward fills sound-absorbing material, inert gas serves a kind of protective effect to sound-absorbing material, effectively to prevent in bonding process porousness sound-absorbing material to the absorption of the organic molecule produced in organic solvent and solidification process, also the air displacement containing organic solvent and organic molecule can be gone out the rear operatic tunes simultaneously, ensure that the unimpeded of the duct of sound-absorbing material, thus ensure that the performance of sound-absorbing material quick adsorption and desorption, and then ensure that the medium and low frequency performance of loud speaker module reaches re-set target, improve the acoustical behavior of loud speaker module.
The step of inert gas is purged owing to be also included in before the operatic tunes backward fills sound-absorbing material operatic tunes position backward, the organic solvent that the bonding agent when bonding loudspeaker monomer and housing can produce by this step and organic molecule clear out of after the operatic tunes, thus further reduce the probability of sound-absorbing material absorbing organic solvent and organic little point, ensure that the unimpeded of sound-absorbing material duct, further ensure that quick adsorption and the desorption performance of sound-absorbing material, and then further improve the acoustical behavior of loud speaker module.
In sum, loud speaker module packaging technical of the present invention solves the technical problem that in prior art, after loud speaker module, in the operatic tunes, the duct of sound-absorbing material is easily blocked, the volatile substance adsorption that loud speaker module packaging technical of the present invention can effectively prevent bonding agent from producing is on sound-absorbing material, ensure that sound-absorbing material is to the absorption of gas and desorption ability, thus improve the acoustical behavior of loud speaker module.
