A sound emitter (buzzer, buzzer) is a signal device that is used to activate sound waves by processing an electrical signal into sound energy. Its main task is to provide high-quality sound alarm. Varieties of sound emitters: electromagnetic sound emitters – produce special signals: beep or bell; electrodynamic sound emitters – are used in different sound-reproducing equipment; they are divided into the following types: coil, with a balanced anchor, tape, isodynamic, orthodynamic, hale emitters; electrostatic sound emitters – the sound is formed by a thin membrane (loudspeakers, headphones); piezoelectric sound emitters the sound is formed by a piezoelectric element (alarm clocks, electric toys, piezoelectric sensors and microphones); non-traditional sound emitters – a new sound conversion technology has been developed. What is the principle of the buzzer? Most sound devices are arranged according to a similar principle. But the choice of a specific type of buzzer depends on what purpose it is necessary to mount it in the electrical network. First, the emitter receives an input voltage from the electrical circuit and then proceeds to work, releasing a sound signal in a certain mode. If necessary, our professional experts will always help you choose and buy a buzzer that will be suitable for you according to the type and given characteristics. Where are the sound emitters used? Buzzers are widely used in home appliances, electronics and other electronic devices. They are used to give a sound signal or message in the devices. Sound emitters are used in security systems, fire alarms, many alarms, laptops and smartphones. The main functions and purpose of the sound emitter: allows you to monitor personnel security systems; sends sound signals for security systems; guarantees the sound for the alarm when unpredictable situations; protects hazardous areas with a sound signal – if unwanted equipment, products or people penetrate; audible alarm when turning on or stopping work; alarm system during the performance or error in operation of the equipment. In the online store of Eurocom Components, the price of the sound emitter depends on its type and purpose. You can order goods from a trusted manufacturer both in retail (from one) and wholesale (small or large). Delivery works throughout Ukraine.
