[Detailed description of the invention] This is also O regarding the ceramic microphone four-on
for ultrasonic equipment. In the past, ceramic microphones for ultrasonic waves are widely used
for remote control devices, and as shown in FIG. 1, the KIIIi sound wave is converted to a liquid
crystal (υ- 埴 · 2 ′ ′-571 g · −5 μm). In order to obtain an output by amplifying the signal
voltage generated at this 1 // 1 and generating this with the transistor l, as shown in the second
figure, the support base I2 and the bimorph 2 are hard with elastic silicon hardness 1113 having
elasticity Wear and attach corn 7 to the pastry piemorphs o @ 4 # and 9 and the lead vaio which
is placed on the support 10, and connect 4 to 4 to 10! The ceramic micro 7 on 1 / and the
transistor I were respectively embedded in and soldered to the printed wiring base 4 f / J.
Therefore, the space required for the printed circuit board 13 requires a space between the
microphone riff-on 11 and the transistor 1 and there is an interval 11 Il for the remote control
device that is required to be miniaturized. The present invention aims to provide a ceramic
ceramic microphone by integrating the ceramic ramic microphone and the transistor into a small
bowl and reducing the cost of parts of the ceramic '1' (the rumor pile '' '' 572 microphone and
reducing the cost. The third embodiment of the present invention will be described. The
transistor I and a cone 7 tti attached pie rufco are coated with an elastic silicone adhesive 3 and
the bimorph 2 wL abrasive l and the transistor In this embodiment, the lead 41 j and the
electrode 9 are connected to the transistor body-o emitter lead gauze 4-A, t. With the O
configured as above, using the ceramic micro 7 on of the invention of the '0' invention, simply
putting the lead of the transistor, 'm' on the printed wiring board 13, and putting on the
conventional ceramic microphone and transistor Since it operates in the same way as a pipe,
labor required for filling is not necessary, and the conventional O-k 5 i Tsutamicrophone O / 21
and-61, (5) one shot · p7 J 73 two / insert at a friend Since 10% of the crucible 10 is not
required, the material cost is reduced, and the space is sufficient with the ceramic micro 7 on
0410 space, so that the device can be miniaturized. A description of the first-order ultrasonic
miter lower-on and the transistor, FIG. 2 is a front view of the conventional embodiment Oj, and
FIG. 3 is a view of the embodiment of the present invention. /, ..., Lancister λ 00.
