Abstract
The utility model discloses a sound box, comprising a sound box body (1). An upper projecting block (2) and a lower projecting block (3) which are used for preventing a knob or radiation fins of a power amplifier from projecting out of the sound box body are positioned on the upper part and the lower part of the back of the sound box. The sound box is low in manufacture cost and guarantees that the power amplifier can radiate heat normally.
Description
Technical field
The utility model relates to a kind of audio amplifier.
Background technology
The audio amplifier back side of prior art is the plane, so when active power amplifier is installed, give prominence at the audio amplifier back side for fear of power amplifier knob or fin, therefore can establish at the audio amplifier back side heavy stand face, power amplifier is hidden in audio amplifier, broken in transportation or use procedure to avoid outstanding causing outside of power amplifier.But, so not only increased production cost, and can affect the heat radiation of power amplifier.Therefore, for these reasons, demand urgently needing the audio amplifier that a kind of production cost is low and the assurance power amplifier normally dispels the heat, to address the above problem.
The utility model content
The technical problems to be solved in the utility model is, overcomes the defective of above prior art, provides a kind of production cost low and guarantee the audio amplifier of the normal heat radiation of power amplifier.
The technical solution of the utility model is, a kind of audio amplifier is provided, and comprises the audio amplifier body, and the upper and lower at the described audio amplifier body back side is respectively equipped with one and is used for preventing that power amplifier knob or fin from protruding upper protruding block and the lower protruding block of audio amplifier body.
The cross section of described upper protruding block and lower protruding block all is roughly isosceles trapezoid.
Described upper protruding block is provided with a handle.
Described upper protruding block is provided with groove, and described handle is fixed on the opening part of groove.
After adopting above structure, the utility model compared with prior art has the following advantages:
The upper and lower at the audio amplifier body back side of the utility model audio amplifier is respectively equipped with one and is used for preventing that power amplifier knob or fin from protruding upper protruding block and the lower protruding block of audio amplifier body, make so originally to protrude at this external power amplifier knob or fin of audio amplifier and covered by upper protruding block and lower protruding block, thereby avoid being damaged in the audio amplifier moving process.Like this, not only reduce production cost, and guaranteed the normal heat radiation of power amplifier.
As improvement, described upper protruding block is provided with a handle, and this handle has facilitated the movement of audio amplifier to a certain extent.

Fig. 1 is the front view of the utility model audio amplifier.
Fig. 2 is the vertical view of the utility model audio amplifier.
Shown in figure 1, the audio amplifier body, 2, upper protruding block, 3, lower protruding block, 4, handle, 5, groove.
Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
As shown in Figure 1 and Figure 2, a kind of audio amplifier of the utility model, comprise audio amplifier body 1, the upper and lower at described audio amplifier body 1 back side is respectively equipped with one and is used for preventing that power amplifier knob or fin from protruding upper protruding block 2 and the lower protruding block 3 of audio amplifier body, upper protruding block 2 and lower protruding block 3 audio amplifier bodies 1 are an integral body, are all integrated injection moldings.
The cross section of described upper protruding block 2 and lower protruding block 3 all is roughly isosceles trapezoid.
Described upper protruding block 2 is provided with a handle 4.
Described upper protruding block 2 is provided with groove 5, and described handle 3 is fixed on the opening part of groove 5, and described handle 3 is fixed on the opening part of groove 5 by two screws.
Below only be described with regard to most preferred embodiment of the present utility model, but can not be interpreted as it is limitations on claims.The utility model is not limited only to above embodiment, and its concrete structure allows to change.In every case the various variations of doing in the protection range of the utility model independent claims are all in protection range of the present utility model.
