Problems solved by technology

In terms of structure, its coil and paper cone are designed as independent structures, and its structure occupies a large size. After the size and material are fixed, the adjustable range of the coil is fixed, and the frequency of the sound vibration formed by it will be limited within a fixed range. Moreover, the vibration transmission process will produce energy loss, resulting in reduced sound quality

Abstract

The invention relates to an acoustic propagation system, which comprises a planar resonance circuit that comprises a planar resonance body and a permanent magnet, the planar resonance body comprises a metal layer and a flexible film substrate layer, and the metal layer is laminated on the flexible film substrate layer; wherein the planar resonance body comprises a plurality of planar resonance units which are distributed in an array. According to the invention, the integrated planar resonant body is designed, so that the problems that the structure occupied size is large and the sound vibration frequency is limited in a fixed range due to an independent structure in the prior art are solved. The planar resonance body comprises a plurality of planar resonance units, which are distributed in an array, so that accurate frequency control can be realized, and the sound quality is obviously improved.

Description

technical field [0001] The present invention relates to the technical field of sound propagation, in particular to a sound propagation system and a communication terminal. Background technique [0002] The traditional sound propagation process (such as the principle of acoustic vibration) is mainly the vibration of the vibrator and the sound of the paper tympanic horn. The general principle is to put the weak signal of the microphone into the front stage of the power amplifier for amplification and rendering, send it to the rear stage for amplification, and then output the signal current to the voice coil of the speaker, and then vibrate with different vibration amplitudes through the strong and weak voice coil of the current, and then vibrate the speaker paper cone to make sound. [0003] The traditional sound vibration structure includes a vibration circuit, a coil and a diaphragm (such as figure 1 As shown), the vibration circuit can be regarded as a sound source. The s...
