Abstract
The utility model discloses a sound box with an adjustable back sound cavity for a portable electronic device, which comprises a loudspeaker used for being arranged on the portable electronic device, wherein one side of the loudspeaker used for corresponding to the potable electronic device is connected with a telescopic cavity used as the back sound cavity of the sound box, a compression spring used for driving the cavity to do telescopic movement is sheathed and arranged in the cavity, one side of the compression spring corresponding to the loudspeaker is butted against and connected on the loudspeaker, a spring telescopic controller used for controlling the telescopic movement of the compression spring is arranged on the sound box with the adjustable back sound cavity for the portable electronic device, the cavity is in a tubular telescopic folding structure, and one side of the loudspeaker which is not connected with the cavity is buckled and covered with a loudspeaker protective cover. Through the arrangement of the telescopic cavity, the compression spring and the spring telescopic controller, the utility model has the advantages that the sound box can be compressed in the portable electrode device in ordinary times, when the sound effect needs to be improved, the cavity used as the back sound cavity can be driven to expand through the spring telescopic controller by the compression spring, the size of the back sound cavity is enlarged, and the sound effect can be improved.
Description
Technical field
The utility model relates to a kind of audio amplifier, relates in particular to a kind of adjustable audio amplifier in back sound chamber that is used for portable electron device.
Background technology
The quality of audio amplifier tonequality and audio follows the size in loud speaker sound chamber that very large relation is arranged.The size in back sound chamber has tremendous influence to the low frequency part of sound, and the low frequency part of sound is strong to the tonequality influence.Back sound chamber is big more, and bass is just outstanding more, and subjective meeting thinks that sound is more melodious.Therefore, sound chamber, expansion back is to the integral sound effect effect of having greatly improved.Yet in the prior art, be used for such as the audio amplifier on the portable electronic equipments such as mobile phone, walkman and thereafter the sound chamber can't expand owing to be subject to thin, the small size of these carriers always, so tonequality and audio are all very undesirable, problems such as the ubiquity bass is unintelligible, louder volume distorsion.
The utility model content
In view of this, technical problem to be solved in the utility model is: provide a kind of simple in structure, back sound chamber adjustable size, can effectively improve tonequality, solve the adjustable audio amplifier in back sound chamber that is used for portable electron device of problems such as bass is unintelligible, louder volume distorsion.
In order to achieve the above object, the utility model adopts following technical scheme to realize:
A kind of adjustable audio amplifier in back sound chamber that is used for portable electron device, comprise in order to be installed on the loud speaker on the portable electron device, wherein, the telescopic cavity in described loud speaker sound chamber after being connected with as audio amplifier in order to corresponding portable electron device one side, be arranged with in the described cavity in order to drive the flexible compression spring of described cavity, one side of the corresponding described loud speaker of described compression spring is connected on the described loud speaker, also is provided with in order to control the telescopic spring control device of described compression telescopic spring on the audio amplifier that the described back sound chamber that is used for portable electron device is adjustable.
As preferably, described cavity is the telescopic foldable structure of tubular.
As preferably, the side buckle closure that described loud speaker does not connect described cavity has the loud speaker over cap.
As shown from the above technical solution, the beneficial effects of the utility model are:
Compared to existing technology, the utility model is by the setting to telescopic cavity and compression spring and telescopic spring control device, make in the structure of its portable electron device that can be built in limited bulks such as mobile phone, walkman, can make the compression spring and be in compressive state by the telescopic spring control device and be compressed in portable electron device inside such as mobile phone, walkman as the cavity in sound chamber, back, usually use as common loudspeaker, do not influence and carry, do not influence product appearance.When needs improve music effect, can make the compression spring and as the cavity expansion elongation in sound chamber, back by the telescopic spring control device, reach and increase back sound cavity volume, improve the purpose of music effect.

Embodiment
In order to make those skilled in the art can further understand feature of the present utility model and technology contents, see also following about detailed description of the present utility model and accompanying drawing.
See also Fig. 1 to shown in Figure 4; the utility model provides a kind of adjustable audio amplifier in back sound chamber that is used for portable electron device; comprise in order to be installed on the loud speaker 1 on the portable electron device; wherein; the telescopic cavity 2 in described loud speaker sound chamber after being connected with as audio amplifier in order to corresponding portable electron device one side; be arranged with in the described cavity in order to drive the flexible compression spring 3 of described cavity; one side of the corresponding described loud speaker of described compression spring is connected on the described loud speaker; also be provided with in order to control the telescopic spring control device (not shown) of described compression telescopic spring on the audio amplifier that the described back sound chamber that is used for portable electron device is adjustable; described cavity is the telescopic foldable structure of tubular, and the side buckle closure that described loud speaker does not connect described cavity has loud speaker over cap 4.
But the above only is a preferable possible embodiments of the present utility model, is not in order to limit to claim of the present utility model, so the equivalent structure that all utilization the utility model specifications and accompanying drawing content are done changes, all in like manner to be included in the scope of the present utility model.
Claims (3)
