Abstract

A miniature sound box provided with a telescopic resonance cavity comprises a loudspeaker, a sound box upper casing (4), a sound box lower casing (2), an audio cable, an audio plug, a circuit board, and a telescopic resonance cavity, the sound box upper casing (4) being fixedly connected to the sound box lower casing (2), and sound outlets (1) being provided on the sound box lower casing (2). A bottom portion of the sound box lower casing (2) is provided with multiple legs around the sound outlets (1) to support the miniature sound box, so that the sound from the miniature sound box is transmitted downwards from the loudspeaker through the sound outlets (1) on the sound box lower casing (2), thereby preventing dust and sundries from falling into the sound box, and reducing the damage to the sound box inner devices such as the sound outlets (1), the loudspeaker, and the telescopic resonance cavity.

Description

technical field [0001] The invention relates to the field of miniature sound boxes, in particular to a miniature sound box with a telescopic resonance cavity. Background technique [0002] I have applied for a micro-speaker patent in China, the patent application number is 201220386162.X, the micro-speaker includes a speaker, a speaker upper case, a speaker lower case, an audio cable, an audio plug, a circuit board and a telescopic resonance cavity. The upper shell of the speaker is fixedly connected with the lower shell of the speaker. The telescopic resonance cavity is located in the upper shell of the speaker and the lower shell of the speaker. The upper end of the telescopic resonance cavity is connected to the upper shell of the speaker through a transition piece, and the other end is connected to the lower shell of the speaker; And placed in the upper shell of the sound box, the speaker transmits sound outward through the sound hole on the upper shell of the sound box....
