on Introduction, What dose 2m mean is it 2 meters or 2 miles in the specs of the trasmiter, Reply This puts the audio onto the light beam. (if not i have a backup plan). Transmitter Section This wireless headphones transmitter assures a quality reception over 2 meters. The best part is everythinf you need to build it is at Radio Shack. Forget that! The range is about 30-40 feet. And inductance for good measure. C2 couples the audio to IC 1 which amplifies it some more. (no  real reason why) If your going IC the 74HC5555 is quite nice(89MHz at 25°C). 555 AM Transmitter: This is a very simple easy to make AM transmitter if you don't want to use inductors or capacitors and don't mind not having extreme power. 98 $49.99 $49.99. WORKING OF ULTRASONIC TRANSMITTER CIRCUIT: The IC 555 was wired to work as an astable multivibrator which forms the oscillator part of the above circuit. The audio from the IC is then routed to T2 which modulates the power to the LED. 8 years ago 1) If the transmission path is line of sight, the transmission/reception will be significantly improved by using Yagi directional antennas or panel antennas. Designing a simple IR Audio Link Circuit would not be beneficial when compared to the existing technologies but it surely will be a learning experience about the wireless audio transfer. The circuit is able to generate an amplitude modulation signal at 600Khz and you are able to receive it using a plain AM receiver. 3) Yagi antenna is a directional antenna. Alternatively, if you want a Bluetooth audio receiver, this allows you to send, transmit and receive music wirelessly from a Bluetooth enabled device, like a Smartphone to your stereo or Hi-Fi system.We stock trusted brands including Digisender and Denon have a vast choice of wireless audio transmitter products, from HD transmitter and more. If so what are the specs of the receiver. Thanks Lectric Wizard for other circuits, always good to have a few to compare. on Introduction, What is the purpose of using a 555 ic in an am transmitter? The best part is everythinf you need to build it … Electronic Dice for Liars Dice and More. 500mW FM / VHF Transmitter Amplifier / Booster, Audiophile OPA2132 Headphone Amplifier Kit, TDA7000 FM Receiver / TV Tuner / Aircraft Receiver, NJM2035 HI-FI Stereo Encoder / Multiplexer. The reason for not being beneficial is the fact that unlike Bluetooth, IR is line-of-sight communication i.e. The circuit is able to generate an amplitude modulation signal at 600Khz and you are able to receive it using a plain AM receiver. This transmitter receiver circuit is for wireless microphone.The circuit divided into two section are transmitter and receiver section. A decoupling capacitor is needed for battery operation =], Once its assembled you have to tune it and then adjust the audio in ground for optimum audio level and clarity. on Introduction. the 555 is used to produce a 350hz modulation signal. For implementing the entire wireless speaker system, we actually need to make two sets of circuits, a transmitter circuit for transmitting the music signal from the source input as discussed above and a receiver circuit for receiving the transmitted music signal and for playing it in the attached speaker. When you finish your radio, it will look something like mine in the picture above. I was having trouble with audio jack, which was the live pin, and what was just a pin (to fix). This would identify the unit which was disturbed. If I used the standard approach and connected the input to the CV pin, the low impedance of the pin would prevent the circuit from receiving any radio signals. (or do you need to make that to?).
