    Abstract: An optimized moving-coil loudspeaker is described herein. The loudspeaker includes an acoustic-radiating diaphragm that is non-cylindrical shape. The diaphragm is a substantially-planar substrate having uniform density. A moving-coil assembly is coupled to the acoustic-radiating diaphragm. The assembly is configured to move back and forth in a linear fashion. As the assembly is connected to the diaphragm it causes acoustic waves to be emitted from a front surface the acoustic-radiating diaphragm. The acoustic-radiating diaphragm is not supported by a conventional basket, among other differences.

    Abstract: Microphones arranged in an array shape along a longitudinal direction are respectively formed in both the longitudinal side surfaces of a housing 2 with substantially an elongated rectangular parallelepiped shape, and speakers arranged in an array shape along the longitudinal direction are formed in a lower surface. The speaker array forms sound emission beams based on sound emission directivity set according to a conference environment. On the other hand, when the microphone array forms sound collection beams by sound collection signals collected, a talker direction is detected from these beams and an output sound signal corresponding to this direction is formed and also is reflected on setting of the sound emission directivity. Also, when there are plural input sound signals, the sound emission directivity is set according to a use situation of the plural input sound signals.

    Abstract: A microphone unit is provided to minimize the attenuation levels of received sound information, which differs depending upon the distance between the positions of microphones and a sound source. A sound source direction identification system is provided to identify the sound source direction. In addition, a moving head control system is provided, where the moving head control system includes a microphone system for receiving sound from a sound source, a sound source direction identification section for identifying the direction of the sound source by obtaining received sound information, a motor control section for generating an appropriate control command to a head moving motor, and a head moving motor for receiving the control command from the motor control section and moving or rotating a robot head in a direction according to the command.

    Abstract: Near-field sensing of wave signals, for example for application in headsets and earsets, is accomplished by placing two or more spaced-apart microphones along a line generally between the headset and the user's mouth. The signals produced at the output of the microphones will disagree in amplitude and time delay for the desired signal—the wearer's voice—but will disagree in a different manner for the ambient noises. Utilization of this difference enables recognizing, and subsequently ignoring, the noise portion of the signals and passing a clean voice signal. A first approach involves a complex vector difference equation applied in the frequency domain that creates a noise-reduced result. A second approach creates an attenuation value that is proportional to the complex vector difference, and applies this attenuation value to the original signal in order to effect a reduction of the noise. The two approaches can be applied separately or combined.
