Combined type speaker system with front and back precise annular tube composite channels and multiple channels in back direction

Abstract

The invention discloses a combined type speaker system with front and back precise annular tube composite channels and multiple channels in the back direction. By simultaneously mounting precise annular tube composite channels or channel group in the front and back of an alto cone loudspeaker and a bass cone loudspeaker, radiation environment of sound is limited, process of sound transmission radiation and output sound fields are affected, and fidelity and radiant efficiency of radiation sound saves in the front of and on the back of the loudspeakers are improved. When the loudspeaker works in low frequency, the precise annular tube composite channels in the front and back precise annular tube composite channels or channel group is formed by an annular tube sound transformer and an annular sound quality element, total equivalent vibrating quality of the loudspeakers is improved under the coactions of the sound transformer and the sound quality, low-frequency resonant frequency of the loudspeakers is reduced, and low-frequency radiation efficiency is further improved. Vibrators, surrounded by the precise annular tube composite channels and channel groups, of the loudspeakers are avoided from direct interference by external air, so that surface load equalization and front and back load equalization can be kept better, and dynamic reaction speed and the like can be increased.

Description

[0001] Technical field: [0002] The invention discloses a multi-channel rear-direction precise annular tube compound-channel combined loudspeaker system, which belongs to the field of electroacoustic technology. [0003] Background technique: [0004] In daily life, people often use loudspeakers to reproduce sound. After the commonly used electric mid-bass paper cone speakers (including bass, mid-bass, mid-range speakers and full-range speakers, hereinafter referred to as speakers) are completed, the resonance frequency of the resonance system of its low-frequency force ω 0 It's OK, ω 0 Determines the lower limit of the frequency of the sound reproduced by this speaker, and usually takes the speaker installed on the infinite baffle as a reference, indicating that the speaker frequency ω 0 and other indicators. In this case, the loudspeaker placed on the infinite baffle directly radiates and transmits sound to the air in the front and back directions. . [0005] General...

Problems solved by technology

However, because there is a connection gap between the speaker frame, the upper magnetic guide plate and the magnet in the channel, and the upper end surface of the upper magnetic guide plate and the magnet has a reflective surface facing the vibrating body, this is formed by means of these exposed parts of the speaker. The channel is not smooth, and the sound waves are reflected here and cause distortion and sound energy loss. Due to the uncertainty of these distortions and sound energy loss, it affects the acoustic variable transducer implied by CA. The accuracy of the transformation effect

[0021]Third, the sound compliance component CA, the existing problems cause distortion and affect the radiation efficiency, which itself is also helpful for reducing the resonance frequency of the speaker Does not help and also complicates the equivalent circuit, which is not conducive to the simplification and intuitive analysis of the problem

The aforementioned distortion and loss of sound energy, affecting the quality and ability to reproduce sound
