Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Embodiment based in the utility model, those of ordinary skills are not making all other embodiment that obtain under creative work prerequisite, all belong to the scope of the utility model protection.
Embodiment:
The utility model embodiment provides a kind of miniaturization wall type power amplifier, as shown in Figures 1 and 2, comprise shell 1 and be fixed on the circuit board for audio signal is processed in shell 1, circuit board 2 can adopt the circuit board in existing power amplifier, realize power amplification function and other control functions, for particular circuit configurations and the principle of circuit board, those skilled in the art, with reference to existing power amplifier circuit plate, repeat no more herein.
Be understandable that, on circuit board, be connected with for the audio interface entrance of source of sound insertion with for the audio signal after power amplifier is processed being exported to the audio output line of sound-box device, this audio output line is used for connecting sound-box device, during use, with other electric wires together from cabling in body of wall, audio output line is connected on sound-box device, and audio interface entrance is arranged in case surface.
In order reasonably to utilize the interior limited space of shell 1, in the utility model embodiment, circuit board is divided into three sub-circuit boards 21, between three sub-circuit boards 21, by wire, connect, thereby form the power amplification being as good as with available circuit plate and control function, three sub-circuit boards 21 are all vertical with respect to shell 1 front surface 12, according to the integrated function of power amplifier, sub-circuit board 21 can extend the rear end of shell 1, extend the sub-circuit board of shell 1 rear end, when shell is installed on wall, be contained in the terminal box of wall.
Certainly, in other embodiments, if function integrated on power amplifier is also few, the area of circuit board can be established when reducing, now, circuit board does not need to be divided into polylith sub-circuit board, and only adopts a circuit board, this circuit board is vertical or inclination certain angle with respect to shell front end face, makes circuit board can not exceed shell front surface by the projection before backward.While being appreciated that circuit board perpendicular to shell front surface, longitudinal degree of depth of whole power amplifier can be maximum, if circuit board, with respect to shell front surface inclination certain angle, can reduce longitudinal degree of depth of whole power amplifier.
