摘要： A multi-layer electret that can endure a high temperature so as to be processed by surface mount technology (SMT) and has ultra-high charge stability and a method of manufacturing thereof are provided. The multi-layer electret is constructed in such a manner that an FET film of 12.5 nullmnull25 nullm in thickness melting-adheres to a surface of a metal plate, and a PTFE film of 30 nullmnull100 nullm in thickness melting-adheres to the surface of the FEP film. A method of manufacturing the multi-layer electret having ultra-high charge stability comprises a first step of laminating an FEP film on a metal plate; a second step of heating the metal plate on which the FEP film was laminated at a high temperature and applying high pressure thereto, whereby the FEP film and the metal plate melting-adhere to each other; a third step of laminating a PTFE film on the FEP film attached to the metal plate; a fourth step of heating the laminated structure and applying high pressure thereto, whereby the PTFE film melting-adheres to the FEP film; a fifth step of cooling the resulting structure, to accomplish an electret; and a sixth step of charging the cooled electret with charges.

摘要： The present invention relates to a hybrid speaker, having a high-frequency tweeter and a low-frequency woofer formed on the same axis, for improving sound quality by separately emitting a high-frequency sound generated by the high-frequency tweeter and a low-frequency sound generated by the low-frequency woofer. A device according to the present invention comprises: a woofer part for generating a low-frequency sound; a tweeter part for generating a high-frequency sound; a substrate for supplying an electrical signal to coils of the woofer part and the tweeter part; a lower frame for accommodating constituent components on the same axis; and an upper frame coupled to the lower frame to form a speaker housing, and separately having a low-frequency sound emission port for emitting the low-frequency sound of the woofer part and a high-frequency sound emission port for emitting the high-frequency sound of the tweeter part. Since the hybrid speaker, according to the present invention, has a hybrid structure in which the high-frequency tweeter and the low-frequency woofer formed on the same axis are coupled, and the high-frequency tweeter and the low-frequency woofer have respective sound emission ports, performance can be maximized, and since a frame of the high-frequency tweeter can be used instead of a low-frequency woofer cover, a process can be simplified, and thus productivity can be increased.
