Abstract

An acoustical phase inverter comprises a hollow cavity, at least one speaker connected with the cavity and an inverter tube which is connected with the cavity and communicated with the inside of the cavity, wherein the cavity contains a main body part and at least one extending part corresponding to the speaker; a sound cavity is formed in the main body part, a sound channel communicated with thesound cavity is formed in the main body part; the speaker is arranged on the tail of the extending part to seal the sound channel. The acoustical phase inverter has better low frequency response performance, ensures that the low frequency sound has lower degree of distortion, and has better output sound quality. In addition, the acoustical phase inverter has simple structure and smaller volume, and is convenient to carry.

Description

technical field [0001] The invention relates to a sound box, in particular to an inverted sound box. Background technique [0002] As people have higher and higher requirements for the sound quality of portable electronic devices, the built-in speakers of many portable electronic devices can no longer meet the requirements. The existing method for improving the output sound quality of portable electronic devices is to connect portable electronic devices with audio-visual equipment. However, the existing speakers are generally heavy and not suitable for carrying, and the low-frequency response performance of the small speakers is not ideal, and the sound quality of the output sound cannot be guaranteed. Contents of the invention [0003] In view of this, it is necessary to provide a vented speaker with better low-frequency response performance. [0004] A phase-inverted sound box comprises a hollow cavity, at least one loudspeaker connected with the cavity, and a phase-inv...
