Embodiment Construction

[0019] The present invention will be further described below in conjunction with the accompanying drawings and preferred embodiments.

[0020] The miniature sound box with telescopic resonance cavity of the present invention comprises loudspeaker, sound box upper shell, sound box middle shell, sound box lower shell, audio frequency line, audio plug, circuit board, horn net and telescopic resonance cavity, and the loudspeaker net is circular, and the loudspeaker The net is connected with the upper case of the sound box, and the holes on the net of the speaker gradually increase from the inside to the outside.

[0021] Such as figure 1 The horn net 1 shown is circular, and the center of the horn net 1 is a small circle, and the holes on the horn net 1 outside the small circle gradually increase and increase; and, the holes are circled outwards increase; the holes on the same ring are evenly distributed and equal in size; the holes on the straight line passing through the center...

Abstract

The invention discloses a miniature soundbox with a telescopic resonance chamber. The miniature soundbox comprises a loudspeaker, a soundbox upper casing, a soundbox middle casing, a soundbox lower casing, an audio cable, an audio plug, a circuit board, a speaker mesh and the telescopic resonance chamber, wherein the speaker mesh is circular and is connected with the soundbox upper casing, and holes in the speaker mesh are increased gradually from the inside to outside. According to the invention, since the holes in the speaker mesh are increased gradually from the inside to outside, the effects of preventing sundries from damaging a loudspeaker resonance film and protecting the soundbox can be realized, and the sound broadcasting effect is enabled to be better and the sound is broadcast further; in addition, the miniature soundbox is enabled to be more attractive in appearance and an efficacy of protecting the inside loudspeaker is realized; moreover, the noise produced by incompatible resonance can be eliminated, and the sound distortion is restrained to a certain degree.

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 miniature speaker with a telescopic resonance cavity and a speaker net. The patent application number is 201210295177.X. plate, horn mesh and telescoping resonator chamber. The upper shell of the speaker and the middle shell of the speaker are fastened and fixed by the snap ring inside, the middle shell of the speaker and the lower shell of the speaker are fixed by screws, the audio cable is connected with the audio plug and the circuit board, the telescopic resonance chamber is located in the speaker shell, and the speaker net is located in the The upper casing of the speaker and the speaker net can prevent sundries from damaging the speaker resonant membrane and protect the speaker; it can also protect the internal speaker; moreover, it can eliminate the noise gener...
