LPT1109DS-HL-05 Sound transducer: piezo; without built-in generator 40÷105°C

The LPT1109DS-HL-05 is a piezo sound transducer designed for generating audible tones and alerts in a variety of electronic devices. This transducer operates without a built-in generator, requiring an external driving circuit to produce sound. Its compact design and wide operating temperature range make it suitable for diverse applications, from consumer electronics to industrial equipment. The piezo element converts electrical energy into mechanical vibrations, which in turn produce sound waves. The absence of an internal generator allows for greater flexibility in tone generation and control, enabling customized sound profiles and frequencies. The LPT1109DS-HL-05 is a reliable and cost-effective solution for adding audible feedback to electronic systems.

This piezo transducer operates on the principle of piezoelectricity, where mechanical stress applied to the piezo element generates an electrical charge, and conversely, an applied electrical field causes the element to deform. By applying an alternating voltage to the piezo element, it vibrates at a specific frequency, producing sound waves. The frequency of the sound is determined by the frequency of the applied voltage, allowing for precise control over the generated tone. The LPT1109DS-HL-05 requires an external driving circuit, such as a microcontroller or oscillator, to generate the necessary voltage signal. The absence of a built-in generator simplifies the transducer's design and reduces its size, making it suitable for space-constrained applications.

Key specifications of the LPT1109DS-HL-05 include a wide operating temperature range of 40°C to 105°C, ensuring reliable performance in harsh environments. The transducer's resonant frequency is typically around 2.9 kHz, which produces a clear and audible tone. The sound pressure level (SPL) is typically around 85 dB at a distance of 10 cm, providing sufficient loudness for most applications. The operating voltage range is typically from 3V to 12V, allowing for compatibility with a variety of power supply systems.
