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 with a right-and-left pair of microphones, which can change over between an inward position with little phase difference and an outward position, without any intricate operation or complicated structure. The voice recorder (10) includes a right-and-left pair of microphones (12L, 12R). Each microphone (12L, 12R) is fixed to a holder (21) that is rotatable about a rotation axis (RAX), and a sound-collection axis (SAX) of each microphone is tilted to the rotation axis (RAX). Turning each holder (21) by 180 degrees allows each microphone to change over between an inward position where the sound-collecting axes (SAX) of the microphones intersect and an outward position where the sound-collecting axes (SAX) do not intersect. Each microphone is placed offset from the rotation axis (RAX) on each holder (12) in such a direction that the sound-collecting axes (SAX) are spaced apart from each other in a height-direction (Z-direction) while the microphones are in the inward position.

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...
