Problems solved by technology

However, increasing the length and width of the diaphragm will inevitably lead to an increase in the length and width of the speaker, which is contrary to the trend of thinning the speaker
In addition, when the speaker adopts a larger diaphragm, in order to effectively drive the diaphragm, a larger-sized magnet must be used, which will increase the production cost of the speaker

Abstract

The invention provides a loudspeaker. The loudspeaker includes a casing, a magnetic circuit system accommodated in the casing, a diaphragm system and a driving device, and the diaphragm system includes a plurality of diaphragms arranged perpendicular to the moving direction of the driving device and arranged adjacent to the The diaphragm between the diaphragms is used to hinder the air circulation between the adjacent diaphragms, and the partition divides the space between the adjacent diaphragms into two cavities that are not connected to each other. The magnetic circuit system of the loudspeaker generates driving force, which is transmitted to the transmission member through the voice coil, and the transmission member simultaneously drives a plurality of the diaphragms, and the plurality of diaphragms vibrate at the same time, and the vibration phase same. The loudspeaker of the present invention is conducive to improving the sensitivity of the loudspeaker without increasing the size of the diaphragm.

Description

【Technical field】 [0001] The invention relates to the technical field of acoustic-electric conversion, in particular to a multi-diaphragm loudspeaker. 【Background technique】 [0002] As a common sound-to-electricity conversion device that converts electrical energy into sound energy, the loudspeaker plays an indispensable role in the sound reproduction system. The loudspeaker is one of the most critical components in the sound amplifier system, and it is the most important component for the sound amplifier effect. There are many kinds of loudspeakers, and the audio electric energy makes the diaphragm vibrate and resonate (resonate) with the surrounding air through electromagnetic, piezoelectric or electrostatic effects to produce sound. A single-diaphragm design is generally used in existing loudspeakers. The design of a single diaphragm not only makes the radiation range of the speaker small, but also the resonant frequency of the monomer is relatively high, which in turn...
