Abstract
The utility model provides an audio power amplifier for a desktop computer with an embedded machine case, which is arranged at the position of a spare CD (compact disc) drive bin of the machine case of the desktop computer and is powered by a host computer power supply. A power amplification circuit of an active sound box is arranged in a machine shell, of which the size is consistent with that of the CD drive bin of the machine case of the desktop computer; a power supply switch, an indicating lamp, a sound volume potentiometer, a large 4P power supply input socket, an audio signal input socket and a power amplification output socket are arranged on a front-rear panel of the machine shell so as to assemble the power amplifier; the power amplifier is arranged at the position of the spare CD drive bin of the machine case, a large 4P power supply plug of the host computer power supply is connected to the large 4P power supply input socket, an audio output signal of a computer sound card is connected to the audio signal input socket of the power amplifier by a signal wire, a PCI baffle with a left-right sound channel output wire-connecting post is arranged at the output position of a PCI baffle card of the machine case, and the left-right sound channel output wire-connecting post is connected with the power amplification output socket so as to connect an external sound box.
Description
Technical field
The utility model belongs to a kind of audio-frequency power amplifier, embeds and is installed in the vacant CD-ROM drive bin location of desktop computer case, and powered by computer host power supply.
Background technology
At present, the power amplifier part of computer audio frequency terminal active audio amplifier, be installed in sound box inside, or independently be placed in the host computer periphery, all adopt the independent current source power supply, and most employings is the conventional power source transformer, big potential safety hazard, the big waste electric energy of reactive loss of existing of traditional transformer thermal value; Moreover the various wiring such as power lead, audio signal wire that are used to connect power amplifier are more in disorder.
Summary of the invention
For addressing the above problem, it is a kind of that the utility model provides, and is installed in the vacant CD-ROM drive bin location of desktop computer case, and by the audio-frequency power amplifier of desk computer power supply power supply.
The technical solution adopted in the utility model is: with the power amplifier part of active audio amplifier, be installed in the casing that matches with desktop computer case CD-ROM drive storehouse size, with power switch, pilot lamp, volume potentiometer, big 4P power input socket, the sound signal input socket, and power amplifier accessory power outlet, be installed on the front and back panel of this casing and be assembled into a power amplifier, this power amplifier is installed in the vacant CD-ROM drive bin location of desktop computer case, the big 4P power supply plug of computer host power supply, be connected to the big 4P power input socket of this power amplifier, the audio output signal of computer sound card, be connected to the sound signal input socket of power amplifier through signal wire, at computer housing PCI integrated circuit board outgoing position, a PCI baffle plate that the left and right acoustic channels output wiring terminal is housed is installed, the left and right acoustic channels binding post is connected to be used to refute with the power amplifier accessory power outlet connects outside audio amplifier, be installed in desktop computer case inside thereby reach audio frequency power amplifier embedded.
The utility model benefit is: audio frequency power amplifier is powered by computer host power supply, and independently power transformer need not be installed; Audio frequency power amplifier embeds and is installed in the desktop computer case, has simplified the host computer external connection line.
