Problems solved by technology

In addition, there is a possibility that the left and right earphones may inadvertently switch to the right channel sound output and the left channel sound output respectively
This can adversely affect, for example, the realism that stereo music would otherwise have

Embodiment Construction

[0038] The embodiments of the present invention will be described below with reference to the drawings. 1 and 2 are a side cross-sectional view and a top cross-sectional view of the earphone of the first embodiment, respectively. The wireless earphone 10 is of an inner ear type, and is covered by a housing 11 except for one end of which is equipped with a speaker (audio output portion) 12 so as to be exposed to the outside. A battery 14 and a substrate 13 are provided in the housing 11.

[0039]On the substrate 13, the light receiving parts 15 and 16 and the signal processing circuit 17 are mounted. The light receiving parts 15 and 16 are each formed as a photoelectric conversion element, which receives an audio signal in the form of an optical signal, and converts the audio signal received thereby into an electric signal. The light receiving parts 15 and 16 each have a concentrator 19, such as a lens, at one end thereof. The optical axes A of the light receiving parts 15 and 16 i...

Abstract

The wireless headphone 10 that receives an audio signal P in the form of an optical signal including a right-channel sound signal and a left-channel sound signal and that outputs sound from an audio output portion 12 is provided with first and second light receiving portions 15 and 16 that are disposed so as to be directed in different directions and receive the audio signal P. The wireless headphone 10 compares the S / N ratios of the signals received by the first and second light receiving portions 15 and 16, and, based on the comparison result, switches an output from the audio output portion 12 between right-channel sound and left-channel sound.

Description

Technical field [0001] The present invention relates to a wireless earphone that receives an audio signal in the form of an optical signal and outputs sound. Background technique [0002] A conventional wireless earphone is disclosed in JP-U-H07-011092. These wireless earphones are equipped with a pair of housings, each housing having a light-receiving element for receiving infrared radiation therein, and the wireless earphones receive audio signals in the form of optical signals transmitted from music players or the like. The received audio signal is separated into right channel sound and left channel sound. The right channel sound is output from the speaker equipped in one of these earphones; the left channel sound is output from the speaker equipped in the other earphone. This makes it possible to eliminate the inconvenience that may be caused by connecting the headphone cable. [0003] JP-A-2005-286919 discloses a pair of wireless earphones, each earphone has a switch button ...
