The audio output device generates half-period digital audio signals, which are signals of a half period of the predetermined period, by using first digital audio signals and second digital audio signals that are the digital audio signals converted by the two digital microphones, where the states of the first digital audio signals are each reflected in one of two half periods corresponding to the predetermined period and states of the second audio signals are each reflected in the other half period. The audio output device then converts the half-period digital audio signals, which are generated by the generator, to analog audio signals and outputs the analog audio signals.

In a sound receiver, a sound wave is directly received by microphones at a predetermined phase difference. The microphones are arranged in opening cavities of a casing, at positions that are different from the volume center points of the opening cavities. The microphones are supported by supporting springs in a state of not closely contacting inner peripheral walls. The sound wave received by the microphones is input to a signal processing unit and after a signal component in a predetermined low frequency band is removed by a filter, the resulting sound wave is amplified by an amplifier and is made in phase by a phase shifter and output.

Sound receiver

A sound receiver includes a casing having multiple cavities which house multiple microphones and through which sound waves are received. A first sound wave is directly received by microphones. A second sound wave is reflected by an inner wall of the cavities and changes in phase corresponding to the material of the inner wall. The material of the inner wall differs for each cavity, thereby effecting a different change in phase of the second sound wave at each of the inner walls.

Sound waves having a proper phase difference are received by microphones fixed in a mesh-formed casing, while other sound waves pass through the casing, and reach a front surface of a diffuse reflection member. The randomly uneven front surface of the diffuse reflection member diffusely reflects the sound waves, thereby preventing the reflected sound waves from reaching the microphones at the proper phase difference. Any reflected sound waves that do reach the microphones are received at a phase difference that is different from the proper phase difference and are determined to be noise by a sound-source determining circuit, thereby enabling a sound receiver to receive only sound waves having the proper phase difference, and hence, improving directivity thereof.
