Tiny audio transducer from Transducers USA delivers 80 dBA SPL

摘要

The Model TRSTE-5025 surface-mount audio transducer from Transducers USA produces a very high sound-pressure level (SPL) of 80 dBA minimum in a miniscule 5×5×2-mm package. The top port sound release of the TRSTE-5025 makes it suitable for handling the size constraints of small, battery-operated products such as cell phones, handheld GPS units, and portable alarms. The device operates from a voltage range of 2 to 4Vp/p at 90 mA. Output frequency is 4000 Hz in an operating temperature range of -30℃ to +85℃. The TRSTE-5025 transducers are shipped in a tape-and-reel package that is compatible with solder-reflow production. Pricing is $0.90 each (production quantities).
