Add the following snippet to your HTML:. Read up about this project on. This is a simple FM microphone system transmitter kit is specially designed for radio learners. It's with the features of long transmitting distance, low power consumption, nice layout and so on. User can learn about the FM transmitting principle and also improve their soldering skills. Small kits, but much more useful. The negative electrode is generally connected to the housing. Its role is to sense the weak vibrations of sound waves in the air, and output electrical signals that are the same as the laws of sound change.

With this resistor, the microphone can output the audio signal. This is because the MIC microphone itself has a primary field effect transistor amplifier circuit to match the impedance and increase the output capability. The microphone does not need to have too high sensitivity, otherwise it is prone to acoustic feedback and produces self-stimulating howling.

For high-frequency circuits above 50 MHz, Q is a common-base amplifier circuit. It is the foundation that can form the oscillation finally, because the foundation condition of the oscillating circuit is to must have certain gain, and then there is the feedback of the appropriate phase, it is generally positive feedback. Because of the current in R2 and R3, they will produce a voltage drop across their resistance and affect each other.

As a result, they will automatically stabilize in a certain value state. This is the emitter follower. Changing the capacity of C4, the diameter, pitch, number of turns of the coil L, and the thickness of the enameled wire can change the transmission frequency. The purpose is to make high-frequency signals become radio waves into the sky. Therefore, the antenna is preferably vertically upward, and the length is preferably equal to the wavelength or integral multiple of the radio wave frequency, and the circumference should be open, and no metal objects should be blocked.

Explanation: The wavelength is equal to the reciprocal of the frequency, the frequency changes, the wavelength changes accordingly, the specific length of the antenna is also related to the output impedance, the antenna thickness, etc. If you are pursuing the farthest launch distance, you can do more on your own. The kit is tested by our technicians and the launch distance can easily reach 50 meters or more.

When analyzing the high-frequency state of the circuit, the collector of the transistor Q is the output, the emitter is the input, and the output signal is applied to the input through the C5, which generates strong positive feedback and naturally oscillates. This is the three-point capacitor oscillation circuit. Turn on a mobile phone or radio that can receive FM radio, and then turn on the microphone power, hold the microphone while blowing or pronouncing the microphone, while on the radio Conduct a search until you hear your voice on the radio.

Because the numerical error of the electronic components may affect the transmission frequency. If the adjustment coil is still ineffective, the L welding will be added one more time or reduced, and the above adjustment will be continued after rewelding. The specific length can be determined according to the effect of debugging. Note: The oscillating coil is an insulated enameled wire.

When welding, use the blade to hang off the insulating paint at both ends of the welding to weld it. Log in Sign up. Published July 10, Beginner Full instructions provided 30 minutes 1, Follow Contact Contact.

Specification: Modulation: FM turns the tiny screw on receiver with your screw driver to use a different frequency if interference is experienced Frequency response: How to use: 1. Open the bottom cover of the Transmitter, and then insert the battery into the Transmitter with the correct polarity and close the bottom cover until the click ends. Insert the Microphone's connector into the socket of the transmitter 3. Open the battery cover of the Receiver, then insert the "AA" battery into the Receiver with the correct polarity and close the battery cover 4. Plug the Receiver into the input socket for microphone of amplifier, then remove the switches of the Transmitter or Receiver to "ON" position, the indicator lamps of the Transmitter and Receiver light, it means that the two devices is normal and are ready for working. There is a volume button on the Transmitter and you can adjust the volume by this button. Joom online store offers high-quality products at low prices.
