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

Abstract

The invention provides a loudspeaker box, comprising a shell, a single loudspeaker contained in the shell, and a leakage structure arranged on the shell. The single loudspeaker comprises vibration diaphragm which is used for vibrating to sound. The vibration diaphragm and the shell are spaced to from a front voice chamber. The loudspeaker box also comprises a voice guide channel communicated with the front voice chamber and the external. The front voice chamber and the voice guide channel form a front chamber. The shell also comprises an inner surface, wherein the front chamber is enclosed with the inner surface and the single loudspeaker, an upper surface arranged opposite to the inner surface, and a side surface which is connected with the upper surface and the inner surface. The leakage structure comprises a first opening arranged on the inner surface, a second opening arranged on the side surface, and a leakage channel communicated with the first opening and the second opening. According to the loudspeaker box provided by the invention, the output voice quality is high, and the production technology is simple.

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...
