Abstract
The utility model discloses an intellectual active loudspeaker box, which comprises a power amplification circuit, an energy conversion circuit, a sound effect processing circuit, an audio-signal input port circuit and a power circuit. The intellectual active loudspeaker box is characterized in that the power circuit is provided with a power controlled circuit which is connected with the power circuit and can answer the opening or the closing state of a computer. The utility model has the advantages that the utility model provides the intellectual active loudspeaker box which can be controlled by a computer host machine, the structure is novel and reasonable, the trouble brought by that the present common active-multimedia loudspeaker box which is not controlled by the computer host machine has double switches is avoided, and functions of the computer, such as the wake of a sound switch, etc. are realized.
Description
The utility model relates to a kind of active audio amplifier, specifically, is a kind of audio signal processor that can accept computer control.
Along with the rapid popularization of internet, applications, computer is generally accepted by people as a kind of omnibearing information carrier instrument.And acoustic medium is a kind of as what propagate on the internet, and its application is also very extensive.At present, the sound playing of computer generally realizes by the external a pair of active audio amplifier of a sound circuit (plate or card) of computer self, so active audio amplifier has also obtained unprecedented development in this period.But, also because by frequent use, now common active audio amplifier and computer collocation, the problem that has " computer of an intelligence is not controlled the active audio amplifier that does not have intelligence ", caused can come the switch computer by " soft " means such as software, telephone signal, keyboard, timings after, also must be by the active audio amplifier that manually comes switch to match with computer and use, this not only makes troubles to the user, and the functions such as " switching on and shutting down sound wake up " that makes computer have originally can not realize easily.
The purpose of this utility model just provides a kind of intelligent active audio amplifier that can be subjected to host computer control, its novel and reasonable structure, not only saved present common multimedia active audio amplifier and brought the trouble of dual-switch because of not being subjected to host computer control, again can function provides convenience for computer realizes that sound switch wakes up etc.
Solution of the present utility model is: a kind of intelligent active audio amplifier, comprise power amplification circuit 1, power conversion circuits 2, sound effect processing circuit 3, audio signal input end mouth circuit 4, power circuit 5, it is characterized in that: on power circuit 5, have coupled a replied computer to open or close the power supply controlled circuit 6 of state.Certainly, under suitable situation, also can adopt the circuit of other version.
Also has a coupled Karaoke circuit 7 on the power amplification circuit 1 of the intelligent active audio amplifier described in the utility model.Certainly, under suitable situation, also can adopt the circuit of other version.
The Karaoke circuit 7 of the intelligent active audio amplifier described in the utility model also is connected to a power circuit 6.Certainly, under suitable situation, also can adopt the circuit of other version.
The utility model has the advantages that, multimedia computer and active audio amplifier are taken into consideration, between them, set up control and controlled approach.A kind of intelligent active audio amplifier that can be subjected to host computer control is provided, its novel and reasonable structure, not only saved present common multimedia active audio amplifier and brought the trouble of dual-switch because of not being subjected to host computer control, again can function provides convenience for computer realizes that sound switch wakes up etc.
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is the theory diagram of a kind of intelligent active audio amplifier of the present utility model;
Fig. 2 is the electrical schematic diagram of a kind of intelligent active audio amplifier of the present utility model.
Fig. 1 has described a kind of intelligent active audio amplifier of the present utility model.A power conversion circuits 2 that converts electrical energy into the sound that people can respond to is arranged in this device, with a coupled power amplification circuit 1, power amplification circuit 1 also is connected to a sound effect processing circuit 3, an audio signal input end mouth circuit 4 that is connected with external audio generation equipment also is connected with sound effect processing circuit 3, and sound effect processing circuit 3 also is connected to a card OK circuit 7.Power amplification circuit 1, sound effect processing circuit 3, card OK circuit 7 also are connected to a power circuit 5, are connected to a power supply controlled circuit 6 on power circuit 5.Certainly, under suitable situation, also can adopt the circuit of other version.
Fig. 2 has described the electric principle of an embodiment intelligence of the utility model active audio amplifier.
Power supply controlled circuit in the present embodiment intelligence active audio amplifier is made up of a signals collecting J2, relay S2, state selecting switch S1, hand switch S3.
The electricity principle:
As shown in Figure 2, U1 is an integrated amplifier circuit (TDA1521), and with capacitor C 113, C114, C115, C116, resistance R 109, R110 form the power amplification circuit of this intelligent active audio amplifier.
From the simulated audio signal of computer via connector J1, capacitor C 101, C102, the audio signal input end mouth circuit that resistance R 101, R102 form is input to by potentiometer WXT, WXL, WXV, WXB, capacitor C 103～112, the sound effect processing circuit that resistance R 103～108 is formed, the sound signal of handling through sound effect processing circuit is input to power amplification circuit by capacitor C 113, C114, signal after the amplification is converted to sound by energy conversion device loudspeaker SP101, SP102, thereby realizes the playback of acoustic medium.
Transformer L201, rectification circuit B201, capacitor C 201～204 composition power circuits provide power supply for U1.
The power supply controlled circuit of forming by a signals collecting J2, the relay S2, state selecting switch S1, the hand switch S3 that are connected with recreation pole or MIDI output port on the host computer.Wherein, to be used to select the switch of this intelligent active audio amplifier be to have computer control or user manual to state selecting switch S1.When selecting the user manual, can control the on/off of this intelligent active audio amplifier by hand switch S3.If select computer control, then when the user opened host computer, a signals collecting J2 gathered its starting-up signal immediately, and promoted its contact of relay S2 adhesive, connected the power supply of this intelligent active audio amplifier, made it start working.When the user closed host computer, a signals collecting J2 is loss signal immediately, and this moment, relay S2 abandoned its contact of adhesive, thereby cut off the power supply of this intelligent active audio amplifier, made it quit work.
In foregoing circuit, also include elements such as capacitor C 117～C119, attaching plug A1.
In foregoing circuit, also can add preposition promotion circuit, Dolby circuit, surround sound treatment circuit, phase place positioning circuit, signal mixed circuit etc. as required.The appropriate circuitry that foregoing circuit can adopt existing ripe circuit or develop later on.
