Buzzer & Transducer

An electronic buzzer with integrated structure, which is powered by DC voltage. It is widely used as a sound device in electronic products such as computers, printers, copiers, alarms, electronic toys, automotive electronic equipment,telephones, timers and so on.

Speaker

It is a very common electroacoustic energy conversion device, which can be seen in electronic and electrical equipment producing sound.

Ultrasonic Sensor

Ultrasonic sensor is a device that uses high-frequency sound to measure distance. These sensors, also known as transceivers, work similarly to sonar. Sonar is mainly used underwater, and ultrasonic transceiver can be used in air.

Microphone

Easy to use; Compared with condenser microphone, it does not need additional preamplifier and no polarization voltage, so it does not need to feed power to it; Firm and reliable, long service life and stable performance; Low noise level. In addition, the price is relatively cheap. However, the instantaneous response and high frequency characteristics are not as good as those of capacitive type.

Receiver

Determine the carrier phase observation value for positioning. Since the influence of ionospheric delay cannot be effectively eliminated, the single frequency receiver is only suitable for precise positioning of short baseline (< 15km).
