The Futong Ying LB07 4Ω5W resonant speaker datasheet provides dimensions, power ratings, impedance, frequency range and reliability test results.
The LB07 4Ω5W is a permanent‑magnet dynamic resonant speaker designed for compact audio applications. It features a 44 mm diameter diaphragm and a total height of 29 mm, making it suitable for space‑constrained installations.
Key specifications include a nominal impedance of 4 Ω, nominal input power of 5 W (maximum 10 W), a usable frequency band from 100 Hz to 15 kHz, and an output SPL of 86 dB. The speaker also meets extensive reliability tests such as continuous 10 W load for 96 hours, heat, cold and humidity endurance. This manual is written in Chinese.
