TRANSMITTER FOR TRANSMITTING AUDIO SIGNALS VIA INFRARED LIGHT, INFRARED AUDIO SYSTEM FOR TRANSMITTING AUDIO SIGNALS VIA INFRARED LIGHT, AND METHOD OF MAKING TRANSMITTER FOR TRANSMITTING AUDIO SIGNALS VIA INFRARED LIGHT

摘要

PROBLEM TO BE SOLVED: To provide a transmitter for transmitting audio signals via infrared light.SOLUTION: A transmitter for transmitting audio signals via infrared light comprises a first mounting board, and a first plurality of narrow angle LED emitters and a first plurality of wide angle LED emitters attached to a front surface of the first mounting board. The first plurality of narrow angle LED emitters and first plurality of wide angle LED emitters are configured to emit a beam of infrared light having a wide portion and a narrow portion; the wide portion is proximate to the LED emitters and the narrow portion is distal to the LED emitters. An infrared audio system includes a transmitter and an expansion transmitter. The expansion transmitter may include a second plurality of narrow angle LED emitters and a second plurality of wide angle LED emitters. A method of making a transmitter comprises the step of attaching a plurality of narrow angle LED emitters and a plurality of wide angle LED emitters to a mounting board of the transmitter.SELECTED DRAWING: Figure 1
