Purpose of the development: Compact piezoelectric transducer PET-1 is designed to convert electrical signals into audible sound range and back.

Recommended application field: The transducer may be used for a wide range of equipment. It can be implemented in enterprises and organizations of the Ministry of Industrial Policy of Ukraine and private industry.

Technical characteristic: 1. Frequency range, Hz: 1.5 - 9.0. 2. Sound pressure level at a distance of 0.5 m at a frequency of 3 kHz at supply voltages of 10 V, dB, not less than 70. 3. Amplitude value of the supplied voltage, no more than 180. 4. Output voltage mode microphone mV, not less than 20. 5. Electrical resistance of alternating current at a frequency of 2 kHz, k is not more than 10. 6. Electric capacity, nF, max 15. 7. Overall dimensions, mm, not more: 36h4. 8. Weight, g, not more than 6.

Advantages over analogues: The essential features of technical solutions converter has several advantages over similar products. In particular, it has higher electroacoustic parameters, as well as the best design solutions that simplify the installation of equipment in it.

The development stage readiness: Introduced in production

Technical and economic effect: Economic benefits of development based on use for its production of Ukraine resources, group methods of production, absence of precious materials, low labor intensity. The estimated cost of one converter with serial 100000 pcs. per year is $ 0.5, which is significantly less than peers.
