Specific implementation mode
Technical solution of the present invention is described without limitation below in conjunction with attached drawing, in order to which the public is more preferable
Ground understands the technology contents.
Embodiment
As shown in Figure 1, a kind of electromagnetic type Wireless pickup device, is fixed on guitar sound hole position, including shell 1, it is described
Electromagnetic pick-up is equipped in shell 1, the electromagnetic pick-up is sequentially connected prime audio signal processing circuit, audio frequency phase electricity
Road, the wireless output transmitting module of the audio frequency phase circuit connection and wired output circuit.
Wherein, the electromagnetic pick-up includes magnetic pole, is wound with copper wire outside magnetic pole, the outside of the magnetic pole is located at shell 1
In the trepanning on surface, the magnetic pole is located at string lower end.
Copper wire in electromagnetic pick-up is wrapped in magnetic pole, and during playing, string occurs to vibrate and be transferred to magnetic pole,
To generate induced current, by conducting wire by the electric signal transmission of generation to prime audio signal processing circuit and voicefrequency circuit,
Signal is handled, since the faradic electric signal of generation is weaker, at this point, can by prime audio signal processing circuit
To carry out gain amplification disposal to weaker signal.
When using stereo set, user may use multiple and different sound pick-ups, it is also possible to use other sounds
Frequency equipment uses simultaneously, is possible to the problem of opposite in phase occur in this way（Namely output audio volume control is opposite）, make output
Audio frequency is cancelled out each other, and the effect that sound equipment overall performance comes out is exactly：Bass is thin, and medium-high frequency penetration power is deteriorated, and leads at this time
Phase circuit is crossed, the phase of electric signal can be adjusted, overall effect is made to enhance.
After phase circuit, wired output circuit and wireless output transmitting module, wired output circuit are being separately connected
Connect wired output port, wired output port can be fixed on the panel sides of guitar, can also be separately provided connecting line and
Wired output port.Phase circuit is also associated with wireless output transmitting module, can be by signal by wirelessly exporting transmitting module
It is transferred to recipient, recipient connects speaker by audio jack, wherein wireless reception module is equipped in recipient, for connecing
The signal launched by wireless transmitter module.
