Abstract
The utility model discloses a mini sound box which comprises a box body and a loudspeaker. The mini sound box is characterized in that a telescopic mechanism is disposed inside the box body, the loudspeaker is arranged on the telescopic end of the telescopic mechanism, a gear reducer is disposed inside the box body, the gear reducer is used for controlling movements of the telescopic mechanism, the telescopic mechanism comprises a first telescopic joint and a second telescopic joint connected with the first telescopic joint in a sleeved mode, the loudspeaker is positioned inside the first telescopic joint, sealing silica gel is arranged inside the telescopic mechanism so as to guarantee tightness of cavities, and a battery and a printed circuit board assembly (PCBA) panel are arranged at the bottom portion inside the box body. According to the mini sound box, the telescopic mechanism can extend outwards when a sound box works to expand the size of the cavities, so that the sound cavity size can meet requirements of electroacoustic designs of the mini sound box and good sound quality can be showed. Meanwhile, ornamental values of products are enhanced. The mini sound box is simple in structure and convenient to use.
Description
Technical field
The utility model relates to audio amplifier, says with having more, relates to a kind of better mini audio amplifier of tonequality that comprises casing and be located at the casing inside trumpet.
Background technology
At present, general mini audio amplifier is the fixed cavity structure.The electroacoustic techniques of audio amplifier has certain requirement to the size in sound chamber, and little cavity is difficult to good tonequality is presented to the user.Cause the tonequality of general on the market portable mini audio amplifier all can not reach user's requirement.
Summary of the invention
In order to overcome the mini audio amplifier of existing fixed cavity, the problem that acoustical quality is not good, the utility model provides a kind of mini audio amplifier, this a kind of mini audio amplifier is when work, by telescoping mechanism loudspeaker are stretched out, strengthen cavity, make the sound cavity volume of loudspeaker reach the requirement that its electroacoustic designs, present good tonequality.
The technical scheme that its technical problem that solves the utility model adopts is as described below: a kind of mini audio amplifier, and comprise casing and be arranged at the interior loudspeaker of casing, it is characterized in that: be provided with a telescoping mechanism in the described casing, described loudspeaker are arranged at the telescoping mechanism telescopic end.
Be provided with a gear reduction box in the described casing, control the expanding-contracting action of telescoping mechanism through this gear reduction box.
Described telescoping mechanism comprises the first expansion joint and the second expansion joint that is socketed with the first expansion joint, and described loudspeaker are located in the first expansion joint.
Be provided with sealing silica gel in the described telescoping mechanism.
Described casing inner bottom part is provided with a battery.
Be provided with the PCBA plate on described casing inner bottom part, the battery.
According to the utility model of said structure, its beneficial effect is, the utility model, stretches out loudspeaker in the casing of fixed cavity when audio amplifier is worked by telescoping mechanism, makes the sound cavity volume of loudspeaker reach the requirement of its electroacoustic design, presents good tonequality.Also improve simultaneously the sight of product.Simple in structure, and easy to use.
