Abstract

The invention is applicable to the technical field of voice box equipment, and provides a vocal cavity device and a voice box. The vocal cavity device comprises a cavity, a first voice production structure and a second voice production structure, each of the first and second voice production structures is composed of a loudspeaker and a vibrating diaphragm, the loudspeakers and the vibrating diaphragms are arranged on the circumference of the cavity in axial symmetry, an included angle formed by axes of the loudspeakers of the first and second voice production structures is less than 180 degrees, the first and second voice production structures are fixed in the cavity through bolts, and an included angle formed by axes of the vibrating diaphragms of the first and second voice production structures is less than 180 degrees. A plurality of voice production structures are reasonably arranged in the cavity, so that the angle that voice sent by the loudspeakers reaches to a listener is more in line with the acoustical principle, and better acoustic effect is achieved.

Description

technical field [0001] The invention belongs to the technical field of sound box equipment, and in particular relates to an acoustic cavity device and a sound box. Background technique [0002] The speaker is the terminal of the entire audio system, and its function is to convert audio power into corresponding sound energy and radiate it into the space. It is an extremely important part of the audio system, because it is responsible for the key task of converting electrical signals into acoustic signals for human ears to listen directly to. It has to deal directly with human hearing, which is very sensitive. And it has a strong ability to distinguish the timbre of complex sounds. Because the human ear's subjective experience of sound is the most important criterion for evaluating the sound quality of a sound system. [0003] Most of the existing small speakers are a speaker, and the acoustic cavity for the speaker is mostly limited to the narrow space of the acoustic cavit...
