Sounding device and audio equipment

Abstract

The invention discloses a sound production device and audio equipment, and the sound production device comprises a magnetic conductive plate, a first magnetic circuit structure, a second magnetic circuit structure, a bass vibrating diaphragm, a bass voice coil, a treble vibrating diaphragm and a treble voice coil. The first magnetic circuit structure comprises a first magnet and a first washer, the first washer is fixedly connected to the side, away from the magnetic conductive plate, of the first magnet, the first washer comprises a first sub washer and a second sub washer annularly arranged outside the first sub washer at intervals, and a high pitch magnetic gap is formed between the first sub washer and the second sub washer; the second magnetic circuit structure is annularly arranged outside the first magnetic circuit structure at intervals to form a bass magnetic gap, and the bass voice coil is arranged corresponding to the bass magnetic gap; the high-pitch vibrating diaphragm comprises an edge part and a central part, the high-pitch voice coil is connected between the edge part and the central part and is arranged corresponding to the high-pitch magnetic gap, and at least the edge part is of a plane structure. According to the technical scheme, the structure of the high-pitch vibrating diaphragm is optimized, so that the high-pitch performance of the sound production device is guaranteed, and the use experience of a user is improved.

Description

technical field [0001] The present invention relates to the technical field of electro-acoustic conversion, in particular to a sound producing device and audio equipment. Background technique [0002] The sound-emitting device is an important acoustic component in audio equipment. It is a transducer device that converts electrical signals into sound signals. Audio equipment includes earphones, stereos, mobile phones or computers. Nowadays, the market is increasingly pursuing full-band sound quality. In order to meet the full-band sound quality, many multi-unit sound-generating devices combined with tweeters and woofers have emerged, that is, a tweeter and a woofer are placed in one sound-generating device. However, in the existing multi-unit sound-emitting device, the diaphragm structure of the tweeter unit is unreasonable, which leads to unsatisfactory high-pitched performance of the sound-emitting device, and brings a bad use experience to the user.
