Problems solved by technology

The traditional sound box is a cavity, and the high, medium and bass speakers are installed on the cavity. In this way, when the speaker is working, the anti-phase high, medium and low frequency sounds collide and entangle with each other in the cavity, which is easy to produce a box. Body vibration, sound wave contamination, sound quality distortion
At present, the relatively advanced speakers have a structure of a single-cavity duct box or multiple positive and negative cavity boxes, but either the structure is complicated, or the speaker is inconvenient to replace and install.

Abstract

The invention discloses a sound box, comprising speakers and a box body. The sound box is characterized in that the side face of the box body is provided with speaker mounting ports and sound ports; and the sound box is internally provided with independent cavities for a high pitch speaker, an alto speaker and a low pitch speaker, an independent bent pipeline extending from the independent cavities of the alto speaker and the low pitch speaker to the sound ports, and a frequency divider containing cavity. The sound box is optimized in structure, excellent in rigidity of the sound box, hierarchical in sound effect and high-fidelity in tone quality.

Description

technical field [0001] The invention relates to audio equipment, in particular to a sound box. Background technique [0002] The speaker is the terminal equipment of the audio system, and the playback quality of the speaker has a great influence on the performance of the audio system. The structure of the speaker is directly related to the playback quality of the speaker. The traditional speaker is a cavity, and the high, medium and woofer speakers are all installed on the cavity. In this way, when the speaker is working, the anti-phase high, medium and low frequency sounds collide and entangle with each other in the cavity, which is easy to produce a box. Body vibration, sound wave contamination, sound quality distortion. At present, the relatively advanced speakers have a structure of a single-cavity duct box or multiple positive and negative cavity boxes, but either the structure is complicated, or the speaker is inconvenient to replace and install.
