A buzzer or beeper is an audio signaling device, [1] which may be mechanical, electromechanical, or piezoelectric (piezo for short). Typical uses of buzzers and beepers include alarm devices , timers , train and confirmation of user input such as a mouse click or keystroke.
A joy buzzer (also called a hand buzzer) is a practical joke device that consists of a coiled mainspring inside a disc worn in the palm of the hand. When the wearer shakes hands with another person, a button on the disc releases the spring, which rapidly unwinds creating a vibration that mimics an electric shock to the unsuspecting victim. [1]
A buzzer is often constructed by running string through two of the holes on a large button and is a common and easily made toy. A buzzer (buzz, bullroarer, button-on-a-string) is an ancient mechanical device used for ceremonial purposes and as a toy. It is constructed by centering an object at the midpoint of a cord or thong and winding the ...
A piezoelectric speaker (also known as a piezo bender due to its mode of operation, and sometimes colloquially called a "piezo", buzzer, crystal loudspeaker or beep speaker) is a loudspeaker that uses the piezoelectric effect for generating sound. The initial mechanical motion is created by applying a voltage to a piezoelectric material, and ...
Unicode is widely regarded as politically neutral, has good support for both simplified and traditional characters, and can be easily converted to and from the GB and Big5. Furthermore, Unicode has the advantage of not being limited only to Chinese, since it contains character codes for (nearly) every language.
These phenomena can potentially generate vibrations of the ferromagnetic, conductive parts, coils and permanent magnets of electrical, magnetic and electromechanical device, resulting in an audible sound if the frequency of vibrations lies between 20 Hz and 20 kHz, and if the sound level is high enough to be heard (e.g. large surface of ...
The first byte 0x7F is used by some variants to encode codes for some otherwise unavailable Unified Repertoire and Ordering or CJK Unified Ideographs Extension A hanzi (e.g. 0x7F3449 for U+3449 or 0x7F796E for U+796E; [9] notice how the continuation bytes match the UCS-2BE code), and this may include bytes outside of the 0x21–0x7E or even ...
