Double-frame combined-type speaker system with precise circular tube compound channel

Abstract

The invention discloses a double-frame combined-type speaker system with a precise circular tube compound channel. To limit sound radiation environment, influence process of radiation of sound transmission and sound field of output, and improve quality of reproduction and radiant efficiency of the speaking radiating sound waves back and forth, the compound channel or a channel group of the precise circular tube is installed along backward, or both backward and forward of a bass paper cone speaker in the double frame by structuring the double-frame paper cone speaker. When the speaker works in low frequency, the precise circular tube compound channel is composed of a circular tube sound transformer and a circular tube sound quality element, therefore, equivalent vibration quality is increased under combined action of the sound transformer and the sound quality element, resonant frequency of the speaker in low frequency is reduced, and low frequency radiant efficiency is further improved. An oscillating body of the double-frame speaker enclosed by the compound channel or the channel group of the precise circular tube is free from direct disturbance of outside air, and further, surface loud balance and back and force load balance are maintained, and dynamitic reacting speed of the oscillating body is improved.

Description

Technical field: [0001] The invention relates to a combined loudspeaker system with a double-basin frame precision annular tube compound channel and belongs to the field of electro-acoustic technology. Background technique: [0002] 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 rear directions freely, and its ω 0 =, M M Indicates ...

AI Technical Summary

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
