Description
Technical field
The utility model relates to electric guitar wireless transmit technical field.
Background technology
Electric guitar is a kind of musical instrument that liked by people.Electric guitar needs an audio wire and sound equipment to join, and it then is subjected to the restriction of audio wire when playing, and it is not suitable for the player and plays under current intelligence; Moreover it is not suitable for the player and practises at premises, and transferring conference because of acoustics volume influence neighbours' rest, and acoustics volume is turned down and influenced actual playing effect.Thus, many worries have been brought to every aspect.
Summary of the invention
The utility model provides a kind of electric guitar wireless launcher, it and the corresponding cooperation of existing radio, and it can solve the restriction that is subjected to audio wire that prior art exists, and is not suitable for the problem that the player plays under current intelligence.
The purpose of this utility model realizes by following technology: the electric guitar wireless launcher, it has K switch, K switch one end resistance in series R1 combination hub S1, another termination power of K switch E positive pole, power supply E minus earth, socket S2 ground connection, K switch one end resistance in series R2 connects triode V1 base stage, socket S1 series capacitance C1 connects triode V1 base stage, and K switch one end resistance in series R3 connects triode V1 collector, triode V1 grounded emitter; K switch one end resistance in series R4, capacitor C 3 ground connection; Triode V1 collector series capacitance C2 connects triode V2 base stage, and the node of the node of triode V2 base stage, capacitor C 2 and resistance R 4, capacitor C 3 joins, and K switch one end series capacitance C4 connects triode V2 collector, triode V2 emitter resistance in series R5 ground connection; Telefault L1 and capacitor C 4 are in parallel, and the number of turn of telefault L1 is joined with spacing adjustable side series capacitance C7 and emitting antenna ANT; Triode V2 collector series capacitance C5, C6 ground connection; Capacitor C 5, C6 node connect triode V2 emitter.
The beneficial effect that the utility model can produce: the utility model is installed on the existing electric guitar, the voice signal of electric guitar amplifies, vibrates and realize that frequency modulation (PFM) is transmitted to radio through the utility model during performance, insert by the radio fm band, so need not connect sound equipment by audio wire, it can arbitrarily be played the player under current intelligence and come true; Moreover by wireless receiver J-Horner, the player can be with earphone to practise at premises, neither influences neighbours and has a rest, and can monitor the actual playing effect of oneself again.
