Abstract

The invention discloses a natural horn-type mini speaker with a reversal phase structure. The mini speaker comprises a speaker body, a loudspeaker slot is arranged in the speaker body, a loudspeaker is arranged in the loudspeaker slot, and the front of the loudspeaker is towards the external of the speaker body; a natural horn type reversal phase tube is arranged in the natural horn type mini speaker with the reversal phase structure, and is a hollow tube with a spiral plane; one end of the center of the natural horn type reversal phase tube is communicated to the external of the speaker body,and a passive vibrating diaphragm is arranged at the center of the natural horn type reversal phase tube; the other end of the natural horn type reversal phase tube is communicated with the loudspeaker slot. The structure of the invention can acquire high tone quality on the mini speaker, and the unexpected technical effect is obtained.

Description

technical field [0001] The invention relates to the field of sound technology, in particular to a miniature sound box with a natural horn type inverted structure. Background technique [0002] As we all know, the larger the sound unit, the larger the volume of the speaker, and the better the sound quality, but this conflicts with the current social trend of portability and mobility. Today, mobile phones are becoming thinner and lighter. Portable speakers with better sound quality, especially for the development of portable surround sound systems, the use of miniaturized sound units is the key to technical realization. In the interior of small speakers, it is necessary to fully consider the impact of materials, sound cavity structures, and manufacturing processes. Sound quality impact. [0003] The front and back of the diaphragm of all speakers will generate sound waves, but their phases are opposite. If there is no partition, the output will be close to zero due to the can...
