Application Laid-Open No. 52-13301 ° 0 (1977) 2.1 Internal agency serial number
specification-Name of the invention with a pseudo head 葦 sound collector parabola spherical
body having a main body and a mounting member for attaching a sound collection microphone
in the vicinity of its inner surface focus; A pseudo-head combined musical tone apparatus
comprising a pair of left and right pseudo-auricle pieces provided at the opening edge, and an
attachment means for attaching a pair of microphones formed on the body of the cough pseudoaural piece.

DETAILED DESCRIPTION OF THE INVENTION The present invention is a pseudo-hera that
performs binaural sound pickup (pinaural sound pickup) 7 combined use Qtt1. Conventionally, as
a stereo microphone device that performs binaural sound pickup, a microphone unit is attached
to the rain leak of an arc-shaped elastic pipe, respectively, and a pair of microphone dinitts are
attached with projections for insertion of the external ear canal. Although the g11 @ diagnostic
type is known where the cord is derived from the central part of the pipe, this biting device n @
i1 is attached to the human ear and collected, so it is picked up by that ear If it takes a long time
to collect sound with a characteristic or different ', it will be painful to attach it to the equipment
tube head, and if the sentence head is moved too much, unnatural sound may be collected, etc.
There was a drawback. In view of the above, the present invention proposes a pseudo-head dualpurpose sound collector so that sound can be collected from one direction as well as binaural
sound pickup without such a defect. Embodiments of the present invention will be described
below with reference to the drawings. First, referring to FIG. 1 and FIG. 2, an embodiment of the
present invention will be described. In the drawing, the entire tube of the pseudo head combined

*, and the main body 111 is ball-removably mounted to the mounting portion (10a).
In the mounting member (5) provided on the inner surface C1m), the pseudo head combined
fruit f mounted surface (lb) @ configured as described above is used as a pseudo head and is used
as a musical tone instrument When a sound collection microphone (2) is attached to perform
sound collection and is used as a pseudo head, a holding recess t81 provided outside sigma 1 (lb)

of a human being In combination with the same shape Tl-1L, both left and right artificial pinna
pieces, a pseudo head very close to the human head is formed, so the same collection
characteristics as when using the human head is obtained. Unlike the head of the person 1 which
can be obtained and can not move unnecessarily, it can be stably harvested over a long period of
time, and the natural ear canal picking is ciT disease. Father, two heads of pseudo head and tone
