Abstract

The invention relates to a closed pore foam electric loudspeaker comprising a seat body, a magnet body, a folding ring body, a voice coil body, a substrate membrane, a closed pore foam board, a positive electrode connection terminal and a negative electrode connection terminal, wherein the magnet body is installed in a mounting concave cavity of the seat body, the folding ring body is of a foldingring body structure formed by stacking an upper half ring body with a lower half ring body and provided with a hollow ring passage, the closed pore foam board and the substrate membrane are stacked and assembled together and are installed in a concave ring cavity hole of the folding ring body to form a closed pore foam vibration basin body of the loudspeaker, the closed pore foam vibration basinbody is connected with a groove wall of a concave cavity groove via an outer ring edge of the folding ring body to be installed in the concave cavity groove of the seat body, the voice coil body is arranged between the closed pore foam vibration basin body and the magnet body, and the positive electrode connection terminal and the negative electrode connection terminal are electrically connected with the voice coil body via electric wires. The closed pore foam electric loudspeaker provided by invention has the characteristics of good frequency response, good sound fidelity, low distortion andgood sensitivity, thereby having excellent sound playback quality and excellent durable performance.

Description

technical field [0001] The invention relates to the field of audio equipment, in particular to an electric loudspeaker. Background technique [0002] Among the existing electric speakers, cone speakers have the largest market share, and the application technology and production process are the most mature. The diaphragm material of the cone speaker is mainly pulp material. In order to increase its rigidity, internal damping and waterproof performance, the pulp is often mixed with wool or kapok, silk, carbon fiber, flax and other materials. No matter how to improve the structure or structure of the cone loudspeaker based on the material properties of the existing cone speaker, it is difficult to further greatly improve the sound reproduction quality. [0003] At present, there is another kind of dynamic speaker on the market, which is the flat-panel dynamic speaker launched by NXT Company. The sound vibration principle of the flat-panel electric speaker is completely differ...
