Title:
WIRELESS MICROPHONE
Document Type and Number:
WIPO Patent Application WO/2010/116597
Kind Code:
A1
Abstract:
A wireless microphone (1) transmits audio signals by means of infrared rays. A plurality of infrared light emitting elements (17) are attached on a substrate (15) in the wireless microphone (1), and at least one infrared light emitting element (17) is disposed on each of the both surfaces of the substrate (15). A plurality of infrared light emitting elements (17) may be arranged on each of the both surfaces of the substrate (15) and the infrared light emitting elements (17) may be radially disposed. Infrared rays can be radiated around the microphone (1) even without providing an exclusive substrate for the infrared light emitting element (17) in addition to the substrate (15). Thus, the wireless microphone which has infrared rays radiated around the microphone and has a simple structure with a small number of components and improved productivity is provided.
