Midrange Compression Driver

Abstract

An alto voice compression type drive device comprises a high voice cylinder body, a magnetic circuit system, a vibrating diaphragm component, a compression type equalizer, a diffusion type equalizer and a lining cap, wherein a plurality of heat dissipation rib columns are arranged in the high voice cylinder body, the magnetic circuit system is placed in the high voice cylinder body, and contacted with the heat dissipation rib columns, the vibrating diaphragm component is arranged on an opening at the upper end of the high voice cylinder body, the vibrating diaphragm component is composed of a vibrating diaphragm, a voice coil and a plurality of retaining slices, the upper end of the voice coil is fixed on the vibrating diaphragm, the lower end of the voice coil is arranged in the magnetic circuit system in penetration mode, the compression type equalizer is arranged above the vibrating diaphragm component, and connected with the vibrating diaphragm component, the diffusion type equalizer is arranged on the lower surface of the lining cap, the diffusion type equalizer passes through the compression type equalizer, the vibrating diaphragm component and the magnetic circuit system, and is stretched into the bottom of the high voice cylinder body, the voice coil comprises a voice coil skeleton and a voice coil wire wound around the inner side and the outer side of the voice coil skeleton, and high temperature resisting insulation varnish is spread on the surface of the voice coil wire. The alto voice compression type drive device has good heat dispersion performance, can reduce cutting vibration, improves language fidelity under status of a large sound pressure level, and is strong in practicability, and suitable for popularization and application.

Description

technical field [0001] The invention relates to the technical field of audio equipment, in particular to a mid-range compression driving device. Background technique [0002] With the continuous development of scientific research technology, higher requirements are put forward for the performance of speakers, which require high sound quality, speech clarity, high reliability and other characteristics. The above-mentioned characteristics of the speaker are related to heat dissipation performance, diaphragm and voice coil. However, the existing voice coil and magnetic circuit system are installed together. After long-term use, the voice coil will heat up and the temperature of the magnetic circuit system will increase. The voice coil and magnetic circuit system are sealed in the tweeter body, so they cannot dissipate heat quickly. , which will affect the sound quality. [0003] In addition, the existing diaphragm generally adopts a dome-shaped diaphragm, and the dome-shaped ...
