Detailed description of the invention
Fig. 1 is the utility model audio transmission schematic diagram；
Fig. 2 is the connection relationship structural schematic diagram of the utility model；
Wherein, 1, effect device, 2, plate speaker, 3, output connector, 4, piezoelectricity pickup item.
Specific embodiment
Technical solution described in the utility model is described without limitation below in conjunction with attached drawing, in order to the public
More fully understand the technology contents.
Embodiment
As shown in Figure 1, a kind of guitar band tuning piezoelectric type plate speaker pickup apparatus, including piezoelectricity pickup item 4, institute
4 connection effect device 1 of piezoelectricity pickup item is stated, the output end connection output connector 3 of the effect device 1, further includes defeated with effect device 1
The plate speaker 2 of outlet connection, the plate speaker 2 are fitted in the panel inner wall of guitar.Wherein, piezoelectricity pickup item 4 is fixed on
The bottom of lower chord pillow.Piezoelectricity pickup item 4 includes piezoelectric type thin film sensor, and when playing, film receives air vibration signal, vibration
A capacitor is formed between film and the plane electrode of fixation, distance change between the two will lead to the variation of its capacitance,
The both ends of capacitor apply the voltage of fixed frequency and size, are just changed by the electric current of capacitor, thus by the vibration of sound
Dynamic signal is converted into electric signal, is then passed to effect device 1.
Wherein, effect device 1 includes being sequentially connected prime audio signal processing circuit, audio frequency phase circuit, DSP audio mould
Block, wired output circuit and digital audio power amplifier.
Wherein, prime audio signal processing circuit is by the electric signal that piezoelectricity pickup item 4 picks up carries out gain amplification disposal.
Audio frequency phase circuit can make audio frequency occur to avoid opposite in phase to cancel out each other, and thin so as to cause bass, medium-high frequency is worn
The problem of saturating power is deteriorated.
Wherein, DSP audio-frequency module is produced using Shenzhen Ying Tong Trend Micro Limited, the DSP of model DSP+MCU
Audio-frequency module, connection delay controlling potential device, reverberation controlling potential device and chorus controlling potential device, electricity on DSP audio-frequency module
Delay knob, reverberation knob and chorus knob are correspondingly provided on the outside of the device of position, for adjusting potentiometer, so as to obtain difference
Audio.
Wherein, DSP audio-frequency module output end connects wired output circuit, and wired output circuit is connected with digital audio effect
(D class) circuit and output connector 3, the output connector 3 are fixed on the bottom of guitar, can connect speaker by cable.
For digital audio effect (D class) circuit, digital audio power amplifier is audio power IC of the work under D class state,
Have calorific value small compared to analog amplifier IC, power conversion rate is high.
Wherein, digital audio effect (D class) circuit output end connects plate speaker 2, the skeleton plane of the plate speaker 2
With guitar panel attachment, plate speaker 2 can generate vibration when there is audio signal input, since plate speaker 2 is fixed on guitar
On panel, therefore vibration can be transferred to guitar panel, vibrate guitar panel together, so as to reinforce the audio of output.
Wherein, it for plate speaker 2, is produced in the present embodiment using Quanzhou Ai Di sound Electronic Science and Technology Co., Ltd.
, the plate speaker 2 of model S44CP08-430-R, the skeleton of plate speaker 2 is fixed on the panel inside guitar, is being incited somebody to action
When signal is transferred to plate speaker 2, plate speaker 2 starts to vibrate, and transmits these vibrations to guitar panel, sends out guitar panel vibration
Sound plays effect to improve.
Certainly, it for effect device 1, is also connected with equipped with switching circuit, charging circuit and the power switch of outer surface, electricity
Display lamp, charging interface and battery, due to switching circuit, charging circuit, battery and the power switch of outer surface and charging
Interface is not belonging to the invention main points of the utility model, therefore, according to structure in the prior art and mounting means.
It should be understood that it is not limitation to the technical solution that above content, which includes attached drawing, in fact, identical or
