Date: November 2-4, 2021Location: Shanghai New International Expo Centre（SNIEC）Address: No.2345 Longyang Road, Pudong New District, Shanghai, ChinaHall: E1Exhibition booth No.: 1B233 Manorshi was founded in 2003. We are passionate about the electronic component industry. Our company manufactures a
+The soldering temperature and soldering time of the buzzer will directly affect the deformation coefficient of the buzzer, thus affecting the buzzer sound. May cause the buzzer sound to become small, no sound, hoarseness, etc.In order to avoid the above problems, we hope that customers can refer to
+Introduction of HC-SR04HC-SR04 is a very popular sensor for measuring distance. It emits ultrasonic waves at a frequency of 40KHz. The ultrasonic waves travel through the air. If there are objects or obstacles in the path, it will bounce back to the module. Taking into account the propagation time a
+Ultrasonic sensors are devices that convert ultrasonic signals into other energy signals (usually electrical signals) to measure distance from the sensor to the target object. Ultrasonic wave is a mechanical wave with a vibration frequency higher than 20KHz and it has the characteristics of high fre
+Working Principle of Piezo buzzerThe piezo buzzers use piezoelectric materials. Piezoelectric materials create electricity when stress is applied, and become stressed when electricity is applied.The piezo element is to stick the piezoelectric material on the metal sheet. When an alternating voltage
+The working principle of traditional magnetic active buzzer is electromagnetic induction. The active buzzer has its own oscillation circuit, and the customer only needs to use DC voltage.The working principle of the IC magnetic buzzer is that the chip oscillates a square wave signal with a fixed fre
