speaker box

Abstract

The invention provides a loudspeaker cabinet. The loudspeaker cabinet comprises a housing and a loudspeaker body held in the housing. The loudspeaker body comprises a diaphragm for vibrating and producing sound. The diaphragm and the housing are disposed at a certain interval to form a front voice cavity. The loudspeaker cabinet further comprises a sound guiding channel which connects the front voice cavity with the outside. The front cavity and the sound guiding channel form a front cavity. The housing includes an inner surface which, together with the loudspeaker body, surrounds to form the front cavity, an upper surface set opposite to the inner surface, and a side surface connected with the upper surface and the inner surface. The loudspeaker further comprise a first opening in the inner surface, a second opening in the upper surface, and a leak channel which connects the first opening and the second opening. Projection of the first opening and projection of the second opening do not overlap in the vibrating direction of the diaphragm. The loudspeaker cabinet can provide high output acoustic fidelity and is simple in manufacturing technique.

Description

【Technical field】 [0001] The invention relates to the field of acoustic-electric conversion, in particular to a speaker box. 【Background technique】 [0002] With the rapid development of science and technology, the popularity of audio equipment is getting higher and higher. People's requirements for audio equipment are not limited to video and audio playback, but also require more requirements for the reliability of audio equipment. Especially with the advent of the 4G era, mobile multimedia technology has also developed. Many audio devices have a variety of entertainment functions, such as video playback, digital cameras, games, GPS navigation, etc., which require the electronic components in the audio devices to be more precise and precise. Compact, however, the more electronic components there are, the less reliable your audio equipment will be. [0003] In audio equipment, the speaker box is a commonly used electronic component. When the sound outlet of the speaker box...

AI Technical Summary

Problems solved by technology

When the sound outlet of the speaker box in the related art has a large resistance or the sound guide channel has a large damping, the mid-frequency sound wave distortion of the speaker box will be very high, which seriously affects the sound quality of the speaker box.

In addition, since the front cavity resonance of the speaker box will amplify high-frequency components to generate high-frequency noise, it will also affect the sound quality of the sound emitted by the speaker box
