Abstract
The utility model relates to a special television bourdon accompanying-sound sound box. After the audio signals of television are input into the sound box, the audio signals are amplified by an audio amplifier. Then the alt and bourdon amplifiers filter and compensate the high and low frequency audios respectively. Finally, the signals are output from a bourdon loudspeaker. Combining the prior electron-acoustic section of the television, the volumes of the television and the utility model can be adjusted to make a mutual coordination and a perfect sound quality.
Description
Technical field
Electroacoustic techniques
Background technology
At present because television set is limited by its product structure, boombox acoustic energy is consumed in a large number and can't effectively be exported, acoustic reflection and interference that its cup effect causes, its intermodulation distortion is increased, medium and low frequency sense of hearing deficiency, definition, stereovision reduces, and the diffraction of high frequency also causes the high band general trend to glide with reflection.The utility model designs for improving the television acoustics environment, is exclusively used in and watches TV programme and DVD playing back, the VCD video disc.
Summary of the invention
The utility model is different from general active audio amplifier, input signal to high, medium and low audio frequency carries out electroacoustic reduction processing, and only effectively compensate and expand by the high and low frequency section to television set, cooperate the original electroacoustic of television set partly to use, can meet or exceed the effect that general active audio amplifier can reach, and reduce production cost because of it does not contain sound intermediate frequency electroacoustic processing unit.
The technical scheme that its technical problem that solves the utility model adopts is: pick out the television field frame level from the tv audio output, be delivered to the utility model audio input port, amplify through audio frequency amplifier earlier, transmit signals to high pitch power amplifier and bass amplifier then respectively, its high pitch and bass part are carried out filtering, amplification respectively, last sound accompaniment by high pitch, woofer reduction television set.Cooperate the volume of television set, adjusted in concert volume of the present utility model is coordinated it mutually, realizes that full range rings the television field frame effect of high-fidelity.
The beneficial effects of the utility model are: simple in structure, and use lower cost can realize being tending towards the seeing and hearing enjoyment of movie theatre effect.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further specified:
Fig. 1 is circuit theory diagrams of the present utility model
J1. audio signal input end among the figure, J2. woofer, J3. high pitch loudspeaker, U1. bass amplifier, U2. high pitch power amplifier, U3. audio frequency amplifier.
Embodiment: the audio signal of television set J1 in figure is sent to U3, is transported to U1 and U2 respectively after amplifying and carries out the electroacoustic reduction and the compensation of high and low sound, at last by J2, J3 output sound.
As shown in Figure 1 as can be seen, do not have the middle pitch power amplifier in this circuit, have only high pitch and bass two parts to form.Therefore the utility model need utilize the original electroacoustic part of television set and be used.
Claims (2)
1. the special-purpose high and low sound sound accompaniment audio amplifier of a television set, television audio signals is flowed to the input of active audio amplifier by the audio output of television set, carrying out the electroacoustic reduction through audio frequency amplifier, power amplifier, loud speaker in the active audio amplifier handles, it is characterized in that, only high audio in the tv audio signal and bass are carried out electroacoustic reduction processing respectively, and cooperate the original electroacoustic of television set partly to use.
2. the special-purpose high and low sound sound accompaniment audio amplifier of television set according to claim 1 is characterized in that, audio frequency amplifier, and high and low sound power amplifier, high and low sound loud speaker coexists in the casing.
