Sounding device and audio equipment

Abstract

The invention discloses a sound production device and audio equipment, the sound production device comprises a magnetic conductive plate, a first magnetic circuit structure, a second magnetic circuit structure, a high-pitch diaphragm, a high-pitch voice coil, a low-pitch diaphragm and a low-pitch voice coil, the first magnetic circuit structure and the second magnetic circuit structure are arranged on the magnetic conductive plate, the first magnetic circuit structure is located in a central area, and the second magnetic circuit structure is located in a central area. The second magnetic circuit structure is arranged on the periphery of the first magnetic circuit structure; a high-pitch magnetic gap is formed between the first magnetic circuit structure and the second magnetic circuit structure, and a low-pitch magnetic gap is formed in one side, far away from the magnetic conductive plate, of the first magnetic circuit structure; the high-pitch voice coil is arranged on one side, close to the magnetic conductive plate, of the high-pitch vibrating diaphragm and corresponds to the high-pitch magnetic gap, and the radial ring width of the high-pitch voice coil is larger than or equal to two times of the axial height of the high-pitch voice coil; the bass voice coil is arranged on one side, close to the magnetic conductive plate, of the bass vibrating diaphragm and corresponds to the bass magnetic gap. According to the technical scheme, the vibration stability of the high-pitch vibrating diaphragm is improved, so that the high-pitch performance of the sound production device 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-generating device, the high-pitched voice coil installed on the tweeter diaphragm causes uneven weight distribution of the tweeter diaphragm, which is not conducive to the high-frequency vibration of the tweeter diaphragm, and affe...
