Abstract

The invention provides a sound wave reflecting device and a sound box including the sound wave reflecting device. Through the way of combining a soft reflector plate with a fixed rod, one end of a control rod is held against the central area of the soft reflector plate, and the soft reflector plate is jacked up to form a protruded reflecting surface; the protruded reflecting surface reflects soundwaves of a horn sound source, the propagation direction of the sound waves is changed, the convergence or divergence of the sound waves can be realized, and different sound effects can be achieved. By using the soft reflector plate, the advancing distances passing through the control rod are different, the degrees of protruding of the protruded reflecting surface of the soft reflector plate are different, and thus the process of controlling the propagation direction of the reflected sound waves becomes possible. In other words, the propagation direction of the sound waves can be controlled bycontrolling the shape of the reflecting surface, different degrees of convergence or divergence of the sound waves can be realized, and thus different sound effects can be achieved.

Description

technical field [0001] The invention relates to the technical field of audio equipment, in particular to a sound wave reflection device and an audio system including the sound wave reflection device. Background technique [0002] In order to improve the user's hearing experience and pursue the stereo sound effect, various sound wave modulation devices are used in the existing audio system. Such as Bang&Olufsen's audio system adopts a conical sound wave reflector, and the sound source emitted by the speaker can realize surround sound after being reflected by the above-mentioned sound wave reflector. [0003] However, the shape of the reflective surface of the conical sound wave reflector is fixed, that is, the sound wave from the sound source of the horn propagates to the reflective surface of the sound wave reflector, and will be reflected at a fixed angle. Sound needs. Contents of the invention [0004] The object of the present invention is to provide a sound wave refl...
