TH27872A - Microphones in speech communication devices - Google Patents

Abstract

DC60 (16/07/40) This invention relates to the voice conductor (5) in speech communicators, for example, terrestrial radios, walkie-talkies, cordless phones, or mobile phones (1). To achieve good sound quality in such phones, a cover (3) is used which reflects speech directed toward the microphone (6) in the body (2) of the phone. By providing an air channel as the voice conductor (5) on the cover and directing it toward the body of the phone and microphone, sound quality can be improved. To avoid the uneven frequency response that often occurs in such voice conductors due to resonance, a conventional noise attenuating material is applied inside the voice conductor along with noise removal by applying a minimum pressure at a specific location for the microphone. This invention relates to the voice conductor (5) in speech communicators, for example, terrestrial radios, walkie-talkies, cordless phones, or mobile phones (1). To achieve good sound quality in such phones, a cover (3) is used which reflects speech directed toward the microphone (6) in the body (2) of the phone. By providing an air channel as the voice conductor (5) on the cover and directing it toward the body of the phone and microphone, sound quality can be improved. The air channel acts as a sound conductor (5) on the cover and directs it to the body of the phone, and the microphone will improve the sound quality. To avoid the uneven frequency response that often occurs in such a sound conductor due to resonance, conventional noise attenuating material is applied inside the sound conductor along with noise removal by applying a minimum pressure at a specific point for the microphone.

Claims (7)
