Abstract

The invention provides a sound box, and the sound box comprises a box body shell, a loudspeaking assembly and a passive disc; the box body shell is provided with a sound mixing cavity, a bass hole communicated to the sound mixing cavity, and a sound leading hole communicated to the sound mixing cavity, and the bass hole and the sound leading hole are arranged at an interval; the loudspeaking assembly is connected to the box body shell and covers the sound leading hole, the loudspeaking assembly comprises at least two loudspeakers used for playing audios, and the sound emitting directions of the loudspeakers face outwards; the driven disc is connected to the box body shell and covers the bass hole; the box shell, the loudspeaking assembly and the driven disc jointly define a sealed space, and the loudspeaker can drive the driven disc to vibrate through air in the vibration sealed space. According to the sound box, a traditional subwoofer is replaced by the sound mixing cavity and the passive disc to give out bass, the sound mixing cavity can automatically balance the vibration airflow displacement of the loudspeakers, the sound pressure of the loudspeakers can be overlapped, the vibration amplitude of the passive disc is increased, the bass is fuller, the bass effect is better, the structure is simple, and the production cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of audio signal conversion equipment, and in particular relates to a sound box. Background technique [0002] The speaker is the terminal of the entire audio system. Its function is to convert audio power into corresponding sound energy and radiate it to the space. It is an extremely important part of the audio system and is responsible for converting electrical signals into acoustic signals for human listen. However, the existing audio system usually has poor bass effect, which affects the user's music experience. If a subwoofer is added, the structure is more complicated and the production cost is increased. Contents of the invention [0003] The object of the present invention is to provide a sound box, aiming to solve the technical problems of poor bass effects in the prior art and increased cost if additional subwoofers are added. [0004] The present invention is achieved like this, a kind of sound...
