摘要 |
A portable infrared sensor and speaker assembly is described which, in one form, includes an elongated array of infrared sensors along respective first and second side portions of a speaker. Infrared reflective surfaces, which may include a portion of the side surface of the speaker, enhance the detection of infrared signals by the sensors. This technology can be used, for example, in infrared signal amplification systems for amplifying a speaker's voice in a classroom or auditorium.
