AI Technical Summary

Technical Problem

The effective sound-producing area of ​​conventional loudspeakers is limited by the product's size, and the diaphragm vibrates without pistons, making it difficult to increase the effective sound-producing area of ​​the vibration system and adapt to the demand for thinner and lighter smart products.

Method used

It adopts a dual voice coil driven dual diaphragm structure. The space between the diaphragms is divided into a front cavity and a rear cavity by a partition plate, and the cavity is isolated by a slit to increase the effective vibration area. At the same time, the viscosity of air flow is used to form high impedance to isolate the cavity. The shell is set with multiple sound holes to enhance the sound wave output.

Benefits of technology

Without increasing product size, the effective vibration area and sound loudness of the vibration system are increased, the internal space is fully utilized, and the driving force and acoustic performance of the voice coil are enhanced.

Abstract

本发明公开了一种发声单体和发声模组,涉及电声能转换技术领域,其中,发声单体包括壳体、磁路系统和震动系统,壳体包括壳本体以及分隔板;振动系统包括音圈、支架、第一振膜和第二振膜;分隔板将第一振膜和第二振膜之间的空间分隔为第一后腔和第一前腔;支架的一端与第一振膜连接,支架的另一端穿过分隔板上的第一贯穿孔与第二振膜连接。分隔板和第一振膜之间形成第一后腔,分隔板和第二振膜之间形成第一前腔,壳本体设有与第一前腔连通的第一前腔声孔以及与第一后腔连通的第一后腔声孔,使得发声单体的总的有效振动面积是第一振膜有效振动面积和第二振膜的有效振动面积的叠加,实现了在不增加产品尺寸的情况下提升了振动系统的有效振动面积。
