With the rapid development of artificial intelligence, the Internet of Things, big data and other technologies, people's living standards continue to improve, security awareness is also getting stronger and stronger, which in turn releases more security needs, promoting the rapid development of the intelligent security market, is expected in 2020, the total market value will exceed 10000 billion yuan. From the trend, the security system is gradually moving towards intelligence by digitalisation and networking.
Intelligent smoke alarm system
In the wave of intelligent change in the security system, intelligent smoke alarm system is developing rapidly. The system integrates smoke sensors, function keys and sound and light alarm actuators, which can monitor the area in real time through the intelligent interconnection platform and automatically alarm for fire incidents. The buzzer, as the core sounding device of the intelligent smoke alarm system, is always on the front line of fire alarm monitoring and reporting. When there is sudden smoke in the area equipped with intelligent smoke alarm system, the built-in MCU of the smoke alarm will detect the smoke concentration through infrared light, combined with the circuit changes, and make a judgement whether there is a fire or not; once the system confirms the alarm, the detector will send out a fire signal, light up the fire indicator (red), and at the same time, activate the buzzer alarm to warn the personnel to evacuate the scene, dispose of the alarm in a reasonable way, and report the alarm information in real time to the Intelligent fire monitoring platform.
Not only intelligent smoke alarm system, buzzer is also widely used in burglar alarm system, equipment alarm sound, and with its high reliability characteristics, become a home life "security sentinel".
As a provider of security alarm devices, Audiowell continuously improves the quality of its products and provides customers with electro-acoustic devices with stable performance and high reliability. Audiowell's electro-acoustic devices have been sold to many countries and regions around the world, and are used in smoke alarms in many homes and offices. Currently, Audiowell's electroacoustic devices are the most popular in the North American smoke alarm market, with an annual sales volume of about 36 million pieces and a share of more than 90%, making them the best choice for alarm devices.
Product Principle
Buzzer is a kind of integrated structure of electronic ringer, its main component is the piezoelectric ceramic sheet, the component uses the principle of inverse piezoelectric effect, through the built-in silver layer of the electric field, so that the ceramic sheet of the mechanical deformation occurs, and at the same time drive the bonding of the vibration plate to expand the sound decibels, to achieve the desired sound pressure effect. The buzzer requires low operating current and low power consumption, and is therefore called a "green product". At present, Audiowell buzzers have been widely used in smoke alarms, automotive electronics, alarm systems, industrial automation equipment and other products.
