A topological horn horn and sound system

Abstract

The invention discloses a topological horn type novel horn and a sound system. The novel horn comprises a box body, a pipeline and a vibration sound source. A first horn mouth and a second horn mouthare formed in the front end of the box body, and an open hole is formed in the rear end of the box body. The first end of the pipeline extends into the box body from the first horn mouth and is connected with the second horn mouth, and the second end of the pipeline is connected with the open pore; the vibration sound source is arranged at the joint of the second end of the pipeline and the rear end of the box body and used for generating surface vibration and air vibration according to audio signal excitation. According to the novel horn, the sound waves generated by the inner surface and theouter surface are in the same phase, and the power of the sound generated by the inner surface and the outer surface cannot offset each other, but can be well superposed together; moreover, the novelhorn not only has the surface vibration of the shell, but also has the vibration of air in the cavity; and therefore, the advantages of better directivity, smaller sound attenuation, higher sound fidelity and the like are achieved.

Description

technical field [0001] The invention relates to the field of electro-acoustic technology, in particular to a topological horn-type speaker and a sound system. Background technique [0002] The horn loudspeaker is an ordinary dynamic structure loudspeaker with a horn installed. It has the advantages of strong directionality, high power and high efficiency. The disadvantage of the horn speaker is that the low frequency response is poor, the frequency band is narrow, and it is easy to produce nonlinear distortion. [0003] The NXT Planar Speaker is a broadband acoustic radiator. The basic structure of the NXT planar speaker is the driver plus the soundboard. This technology completely abandons the design of traditional piston movement, and the soundboard can be a box shell or a plane with a light flat plate. After driving, the entire surface is replaced by a diaphragm that vibrates almost randomly, rather than regularly. After it is stimulated, each area unit on the panel ...
