Description
【Technical field】
The present invention relates to electroacoustic transduction technical field, more particularly to a kind of loudspeaker enclosure and its filling sound absorption powder side
Method.
【Background technology】
In the fast development process of mobile device (such as mobile phone, panel computer or laptop computer), work(of the people to product
More and more higher can be required, in order that entertainment effect is more prominent, therefore loudspeaker also more and more uses loudspeaker combination BOX's
Structure forms loudspeaker enclosure, is experienced with obtaining more preferable low frequency.
Loudspeaker enclosure in correlation technique filling sound-absorbing material can be formed virtually to expand the volume of back cavity in back cavity
Sound back cavity, but general sound-absorbing material is difficult to encapsulate in powdered, therefore, current one is encapsulated into sound-absorbing material
Big technological difficulties.Current encapsulation mainly has following two modes：
Mode 1：Screen cloth is assembled after first powder filling.First sound-absorbing material is put into the accommodating chamber of loudspeaker enclosure, reuse screen cloth
Combined by modes such as gluing, hot pressing with loudspeaker enclosure, seal powdered sound-absorbing material.Because powder particle is smaller, it is packed into
Mouth opening is larger, and sound-absorbing material easily overflows.This method product yield is relatively low, is unfavorable for volume production.
Mode 2：Screen cloth is first assembled, sound-absorbing material is then filled, the aperture for filling sound-absorbing material leads to outside loudspeaker enclosure.Raise one's voice
There is an aperture led to outside loudspeaker enclosure in the region of filling sucting sound material on device case, and first screen cloth is combined with loudspeaker enclosure, then
By aperture toward inside powder filling end shape sound-absorbing material, diaphragm seal is then pasted at aperture to be used to seal.Such accommodating chamber many
Place's sealing, increased gas leakage risk, and may therefore locate sealing actual effect during follow-up use and cause loudspeaker enclosure gas leakage or
Leakage powder.Other diaphragm seal is attached to outside product, and outward appearance is influenceed to a certain degree.
Therefore, it is necessary to provide a kind of new loudspeaker enclosure to solve the above problems.
【The content of the invention】
