Problems solved by technology

[0003] The diaphragm is the main problem of the sound quality of the speaker. Most of the existing mid-range compression drivers use dome sound diaphragms. The sound is very limited for the space utilization of the product and the improvement of the sound quality, and the performance of the dome sound film for the human voice is also very poor

Abstract

The invention relates to the technical field of loudspeaker equipment and discloses an alto compression drive device with double magnetic circuits. The device comprises an upper cover, a central column, a first magnetic circuit, a first vibration plate, a first equalizer and a base which are set in sequence from top to bottom. The device also comprises a second equalizer, a second vibration plateand a second magnetic circuit which are set in sequence from top to bottom. The second equalizer, the second vibration plate and the second magnetic circuit are set between the first equalizer and thebase. In order to solve the problem that in the prior art, heat dissipation is slow, a space utilization rate is low, voice quality improvement is limited and voice representation capacity is low, according to the scheme, the first equalizer and the second equalizer are sleeved together through utilization of the central column and voices are converged to the central column from double channels formed by the first equalizer and the second equalizer, so voice quality of the whole drive device is improved, a whole structure is relatively compact, and space is utilized well; and through settingof the first magnetic circuit, the second magnetic circuit, the first vibration plate and the second vibration plate, heat dissipation speed of the whole drive device is accelerated.

Description

technical field [0001] The invention relates to the technical field of loudspeaker equipment, in particular to a midrange compression driving device with dual magnetic circuits. Background technique [0002] At present, the performance requirements for loudspeakers are getting higher and higher. When the speaker does work, the heat generated is generally transmitted by the air and the contacting parts. In view of the traditional speaker design, the cooling efficiency of the air is limited. The diaphragm and the magnetic circuit are the main media for heat dissipation, and the speed of heat dissipation also affects the life of the speaker. and sound quality. [0003] The diaphragm is the main problem of the sound quality of the speaker. Most of the existing mid-range compression drivers use dome sound diaphragms. The sound is very limited for the space utilization of the product and the improvement of the sound quality, and the performance of the dome sound membrane for the...
