Abstract

The invention discloses a multidirectional meandering sound channel sound device comprising a top cover and a hollow box body. An iron net cover is disposed in the top cover. A horn is disposed in the box body. A control circuit board is arranged on the sidewall of the box body. A meandering cavity is disposed in the box body. A passive sound basin is arranged to the side of the meandering cavity and is arranged on a sound basin support. An approximately sealed sound device inner chamber is formed among the box body, the top cover, the horn, and the passive sound basin. An electric signal outputs sound via the horn. The sound is amplified by the passive sound basin. The low-frequency range of a sound wave is effectively expanded after the sound wave passes the meandering cavity. By means of air compression-expansion and meandering cavity amplification principles and low-frequency effect enhancement, the effective vibration area of the horn to the miniature sound device is enlarged, thereby obtaining a satisfactory effect.

Description

technical field [0001] The invention relates to the field of audio, in particular to a multi-directional labyrinth sound channel audio with reasonable structure, thick sound quality, easy installation, high efficiency and energy saving.
