DESCRIPTION JPS52116219
BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a simplified block diagram showing the use of
the device of the present invention. In the figure, 1 is a lead wire, 2 is a bracket, 3 is an ear, and 4
is an ear
DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a fixing device for
an ear microphone. i A so-called ear microphone that picks up bone conduction sound of sound
transmitted to the ear canal as a microphone used to transmit sound in a bulky environment of
sound is developed, but the sound output is extracted from a structure that converts mechanical
vibration into an electric signal In many cases, noise is picked up by the lead wire, and for
example, even if the body moves and the lead wire is roughly rubbed, such vibration is given to
the electrical signal conversion element through the lead wire to generate unpleasant noise.
Taking this point into consideration, according to the present invention, a part of the lead wire is
fixed to the earlobe to prevent generation of noise due to such vibration, and in the example of
FIG. /// 12 / f 蚤, ・ ・ ・ eight. A part of the metal fitting 2 such as an earring is fixed at an
appropriate position by a single wire, and as a means of fixing, a protrusion 2a which penetrates
the lead wire 10 is provided in a part of the metal fitting 2 in the figure. It is possible to use a
usual fastening means such as screwing, and further, to fix -1ilS of this metal fitting 2 by means
of a hook 5Vc bending metal fitting 2b or a mounting screw, etc. If it is 1b between the constant
* W and the ear microphone main body 4, this portion 1b does not move stably, and even if the
other portion 1a moves freely, its vibration is stopped by the metal fitting 2 Of course, the place
where noise is generated is of course not transmitted to the place where the snow ear
microphone 4 converts the mechanical vibration tube electric signal and operates as a stable
transmitter. In the front view, 5 is the ear canal.
