摘要： A voice signal transmitting/receiving apparatus includes: a device body; a speaker array arranged in the device body and including a plurality of arrayed speaker units; and a microphone array arranged in the device body and including a plurality of arrayed microphones. By thus integrating the speaker array and the microphone array, it is possible to improve the operability of a user, to acquaint the user relatively easily with the error in the set position and to make the device compact.

摘要： The invention provides a sound collection device having little error in a desired directivity. The sound collection device includes a unidirectional microphone 12A, a unidirectional microphone 12B, and a unidirectional microphone 12C which are arranged on one plane. Each of the unidirectional microphones has the maximum sensitivity direction directed toward the inside of the arrangement. Each of the unidirectional microphones has a rear surface (direction of the minimum sensitivity) being open acoustically. Since the maximum sensitivity direction of each of the unidirectional microphones is directed toward the inside of the arrangement, the oscillation plane of each of the unidirectional microphones can be positioned substantially at the center of the arrangement. Thus, by adjusting the gain of the sound collected by the respective unidirectional microphones, the directivity can be freely formed on a flat plane with little error.

摘要： A mute is provided that can be stored together with a wind instrument. A mute 1 comprises a main body portion 10, a rod-like member 50, and an inner head 60. The main body portion 10 comprises a body 20, a head 30, and a connecting member 40. When in use, a large diameter end 21 of the body 20 is connected to a large diameter end 31 of the head 30. When the inner head 60 is in a bell 3, the body 20 is fixed to the inner circumferential face of the bell 3. For storage, the mute 1 is reassembled into a mode for storage in which the body is separated from the head 30, the head 30 is in the head 30, and the inner head 60 is in the head 30. The entire mute 1 reassembled into this mode is in the bell 3.

摘要： A wind instrument includes a tube body; a tone hole tube that has an inner open end formed extending from the outer periphery of the tube body and opening to the inside of the tube body, and an outer open end opening to the outside of the tube body; and a finger pressing plate that, in the radial direction of the tone hole tube, extends from the outer open end of the tone hole tube to the outside of the tone hole tube.
