Kind Code:
A1
Abstract:
Disclosed is a sound production device and an electronic apparatus using the sound production device. The sound production device comprises a housing (5), and a magnetic circuit system and a vibration system respectively fixedly connected to the housing (5). The vibration system comprises a voice coil assembly (1) and a diaphragm assembly (2) fixedly connected to each other, wherein the voice coil assembly (1) is in conduction with an external circuit by means of an electric connection structure; the electric connection structure comprises an inner electric conduction part arranged on the voice coil assembly (1), an outer electric conduction part (4) arranged on the housing (5), and an electric connection part (3) electrically connected with the inner electric conduction part and the outer electric conduction part (4); and at least part of the electric connection part (3) is wrapped inside the diaphragm assembly (2). The sound production device is beneficial to the thinning of a product, and can solve the problem of wire breakage under conditions where the performance is not influenced.
