Abstract

The present invention discloses a doorbell ringing adjustment control device based on piezoelectric sensing. The device comprises a power supply battery, a central controller, a player, a driver, a touch display screen, a piezoelectric sensor, an analog to digital converter and an audio regulator. The central controller is used for generating a first control signal. The driver is used for generating a driving signal. The touch display screen is lighted when the surface of the touch display screen is touched. The piezoelectric sensor is used for detecting touch strength to obtain an analog signal. The analog to digital converter is used for carrying out converting to generate a digital signal. The central controller is also used for obtaining the comparison of a strength value and a preset strength value and outputting a second control signal according to a comparison result. The audio regulator is used for regulating the frequency of doorbell ringing. The player is used for playing. According to the doorbell ringing adjustment control device, the audio of the ringing can be adjusted according to the strength, and the device has the advantages of high automation, a flexible adjustment mode and high efficiency.

Description

technical field [0001] The invention relates to a doorbell ring tone adjustment control device based on piezoelectric induction, which belongs to the technical field of doorbell systems. Background technique [0002] In home life, the role of the doorbell system has become increasingly prominent. It is usually set outside the door for visitors to press. [0003] At present, doorbells in homes are usually wired transmission, and with the development of technology, wireless doorbells are gradually entering office and home life. [0004] For ordinary wired doorbells, it includes the external button circuit, control circuit and audio playback circuit that are connected in sequence, using the buttons to realize the visitor's knocking on the door, and the player is equipped with a ding-dong sound; the supporting connection line is simple to install, and the user can install it by himself; Power-saving design, no power consumption when not working; DC battery is generally used fo...
