Abstract

The invention discloses an acoustic device, which includes: a first compression driver, the first compression driver includes a first diaphragm, and the first diaphragm vibrates to generate a first sound wave; a ring waveguide, the The ring waveguide is arranged opposite to the first compression driver, and forms a first compression cavity with the first diaphragm, and the width of the first compression cavity is close to the highest frequency generated by the vibration of the first diaphragm Sound waves correspond to a quarter of the wavelength. The acoustic device of the present invention can realize uniform diffusion of sound along 360° on a plane perpendicular to the driving direction of the compression driver, thereby improving the sound emitting range of the acoustic device and realizing omnidirectional sound emission.

Description

technical field [0001] The present invention relates to the technical field of acoustics, and in particular, the present invention relates to a loudspeaker. Background technique [0002] Loudspeaker is a common acoustic amplification device, which can effectively restore and play sound, and can meet most audio application scenarios. [0003] But, in some special occasions of use, such as air defense alarm, disaster prevention publicity, etc., it is required that the loudspeaker device has very good omnidirectional consistency, and the sound sent by the loudspeaker in the prior art has specific directivity, which greatly Limiting the range of sound reception is obviously not an ideal loudspeaker device. Contents of the invention [0004] In view of the deficiencies in the prior art, the purpose of the embodiment of the present invention is to provide an acoustic device, by coupling the compression driver with the ring waveguide, the sound can be transmitted along 360° on t...
