Abstract
The utility model relates to a sound box which comprises a base and a box body, wherein the box body is arranged on the base, the base is of a circular shape, and the box body is in the shape of a trumpet. The side surfaces of the box body are provided with four groups of sound amplifying holes, and the four groups of the sound amplifying holes face toward four directions respectively. The upper end of the box body is closed, and the lower part of the side surface of the box body is provided with a volume regulating knob. The stereoscopic sense and the space sense of music are improved through arranging the four groups of the sound amplifying holes in the side surfaces of the box body and enabling the four groups of the sound amplifying holes to face toward four directions respectively. In addition, effects which are originally achieved by two sound boxes can be achieved by only one sound box, thereby saving the production cost, and saving a lot of resources.
Description
Technical field
The utility model relates to a kind of audio amplifier.
Background technology
Existing audio amplifier only is a kind of " black box ", it is the horn mouth that is provided with of single face, music transmission can only be led to a side, can not effectively improve sound quality, when needs have the music of third dimension or spatial impression, generally be that two " black boxes " are set, the directions that the horn mouth subtend is different realize third dimension, waste very big resource.
The utility model content
In view of this, be necessary to provide a kind of raising music third dimension and spatial impression, and the audio amplifier that economizes on resources.
The utility model is achieved in that a kind of audio amplifier, comprises base and casing, described casing is located on the described base, and described base is circular, and described casing is horn-like, the side of described casing is provided with four groups of holes that amplify, and described four groups of holes that amplify are respectively towards four direction.
Further, described casing upper surface sealing.
Further, bottom, described casing side is provided with volume and regulates knob.
The advantage of a kind of audio amplifier that the utility model provides is: by being provided with four groups of holes that amplify in the side of casing, described four groups of holes that amplify are respectively towards four direction, improve third dimension and the spatial impression of music, and only need an audio amplifier just can reach two effects that audio amplifier just can reach originally, save production cost, and saved ample resources.
Description of drawings
Fig. 1 is the structural representation of a kind of audio amplifier of the utility model.
Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.
See also Fig. 1, Fig. 1 is the structural representation of a kind of audio amplifier of the utility model.
Described a kind of audio amplifier comprises base 1 and casing 2, and described casing 2 is located on the described base 1, and described base 1 is circular, and described casing 2 is horn-like, and the side of described casing 2 is provided with four groups of holes 3 that amplify, and described four groups of holes 3 that amplify are respectively towards four direction.
The sealing of described casing 2 upper surfaces improves the volume that audio amplifier is emitted on four sides.
Bottom, described casing 2 side is provided with volume and regulates knob 21, is convenient to control the size of volume.
By being provided with four groups of holes 3 that amplify in the side of casing 2, third dimension and the spatial impression of music are improved respectively towards four direction in described four groups of holes 3 that amplify, and only need an audio amplifier just can reach two effects that audio amplifier just can reach originally, save production cost, and saved ample resources.
The above only is preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of within spirit of the present utility model and principle, doing, be equal to and replace and improvement etc., all should be included within the protection range of the present utility model.
