Embodiment Construction

[0106] Such as figure 1 as well as figure 2 As shown, the voice recorder 10 is a portable compact recorder, and includes a main body 11 and a pair of left and right microphones 12L, 12R. The voice recorder 10 has a recording function for recording voices input from a pair of microphones 12L and 12R, and a playback function for reproducing the recorded voices. The main body portion 11 has, for example, a substantially rectangular parallelepiped shape including six surfaces. The pair of microphones 12L, 12R is provided on one of the surfaces facing each other in the longitudinal direction of the main body 11 .

[0107] In the case of the main body portion 11 of such a shape, generally speaking, the normal posture is as follows: figure 1 as well as figure 2 As shown, the longitudinal direction (X direction) of the main body part 11 is set to the horizontal direction, and the pair of microphones 12L and 12R are directed toward the sound source. Here, based on this normal po...

Abstract

The present invention provides a voice recorder that can be switched between an inward posture and an outward posture with a small phase difference in a voice recorder provided with a pair of left and right microphones without complicating the operation and compromising the structure. complication. The voice recorder (10) includes a pair of left and right microphones (12L, 12R). Each microphone (12L, 12R) is respectively fixed to a bracket (21) rotatable about a rotation axis (RAX), and each sound collection axis (SAX) is inclined with respect to the rotation axis (RAX). When each stand (21) is rotated by 180°, the posture is switched between an inward posture in which the sound collection axes (SAX) of each microphone cross and an outward posture in which the sound collection axes (SAX) do not cross. The microphones are disposed on the brackets (21) in an inward posture, offset from each rotation axis (RAX) toward each sound collection axis (SAX) in a direction separated from each other in the height direction (Z direction).

Description

technical field [0001] The present invention relates to a sound recorder for recording sound. Background technique [0002] There is known a voice recorder that records voice input from a microphone (see Patent Document 1). The voice recorder has, for example, an IC memory for recording recorded voice data and a speaker in addition to a microphone, and is capable of reproducing the voice data. Such a voice recorder is also called an IC recorder or the like. Among the voice recorders, there are many voice recorders equipped with a pair of left and right microphones to enable stereo recording. [0003] Among the voice recorders provided with a pair of left and right microphones, for example, there is a system in which two cylindrical microphones are provided on one surface of a box-shaped main body. Among such voice recorders, conventionally, there is known a type in which the posture of each microphone can be switched between an outward posture in which the sound collectin...
