The sound output characteristics of a magnetic buzzer SMD often depend on different factors, including design, specifications, and application requirements. However, some common characteristics regarding volume and frequency can be discussed.
volume:
Magnetic buzzer SMDs have a unique Sound Stress Level (SPL), usually measured in decibels (dB). SPL displays the loudness of the sound produced by the buzzer. The volume of a magnetic buzzer can range from a fairly low SPL for quiet applications to a better SPL for situations where louder notifications are required. When selecting a magnetic buzzer for a utility, specific sound pressure level requirements should be considered.
frequency:
The sound frequency produced by a magnetic buzzer SMD is mainly affected by the structure and design of the buzzer. A buzzer consists of a coil and armature that interact with a magnetic field to produce sound. When current flows through the coil, it creates a magnetic force that attracts or repels the armature, causing it to vibrate. These vibrations produce sound waves with precise frequencies.
Magnetic buzzers have a wide range of frequencies, typically ranging from a few hundred hertz (Hz) to several kilohertz (kHz). The frequency of the buzzer depends on elements such as coil windings, armature mass, and mechanical layout. Magnetic buzzers can be designed to generate specific frequencies based entirely on the needs of the utility.
Typically, magnetic buzzers are designed to produce a single continuous tone, but they can also be synthesized by incorporating frequency modulation strategies to provide special tones or melodies. The frequency characteristics can be controlled by the drive signal applied to the buzzer. For example, a specific voltage or waveform can be used to generate a desired frequency or range of frequencies, allowing the buzzer to provide a variety of sound styles.
