[Detailed Description of the Invention] This review relates to a speaker that emits sound using an
electromechanical transducer and an incompressible fluid. In general, the speaker connects a
diaphragm to a voice coil disposed in the air gap of the field aS, and by applying an electric signal
to this voice; It is configured to emit. Is light, and other examples are shown in the first m and the
second m. This 1111. 4 shown in FIG. 2 is an electroacoustic transducer which usually obtains an
ultrasonic wave. The 11th [l # c shown] is joined to the conical repeller 27---1 by a ring-shaped
piezoelectric vibrator 2 through an elastic body 3 such as rubber, etc. It is a thing. In the second
garden, an 8 A-shaped A4 morph oscillator 9 is lost via an elastic member on a terminal @ 7
provided with a terminal 6, and an additional resonance is applied to the 75 Imorph arm 9 The
child 10 is attached and the whole is covered with a case X11. In the configuration as described
above, in the first case, the radiation sound from the piezoelectric vibrator 2 is toothed and
reflected on the slope of the conical reflector 1 and is locally emitted in the central axis direction.
Therefore, the radiation surface is determined by the angle t of the slope of the Ekalli 7 and the
retarder 1 and can be easily defeated, or the braking of the piezoelectric vibrator 8 can not be
performed stably, and the performance as a speaker is Was also unstable. Wearing, even as
shown in the first slQ, the radiation surface is WAclml on top of Case 11, which is a large,
relatively heavy nine, a pleasant -4 and thick. The present invention eliminates one conventional
defect as described above, but is also 3 / -one-frame-- Hereinafter, the present discussion S will
be described with reference to the drawings of one embodiment. An electroacoustic transducer
14 such as a ring-shaped piezoelectric vibrator is disposed on the base substrate 11 via an elastic

member 13 on a large substrate 12 by a synthetic resin or the like. Also on the upper side, the
pressing plate 16 is disposed via the elastic member 13. The presser plate 16 is tightened by a
screw rod 17 inserted into the mounting hole 16 of the substrate 12 and holds the
electroacoustic transducer 14 firmly. A round lead ? 1 s for supplying an electrical signal is
connected to the nine electrodes at the outer peripheral surface and the inner periphery 11 of
the electroacoustic transducer 14. Among them, it is pulled out to the outside through a through
hole 19 provided at a junction Ii [1 @ ha, # @@] connected to the inner circumferential surface,
and the through hole 1 is sealed with a sealing material 20. It is done.
The container portion formed by the base * 1 m and the electroacoustic transducer 14 ░ holding
plate 16 is made of a non-pressurized water, oil or the like so as to be in contact with the
mechanical displacement surface of the turtle air acoustic transducer. Sexual fluid + 11 is being
injected. (1) In such a configuration, when an electrical signal is applied to the electric blue-blue
conversion element 14 via the lead 1 иииииии, the electric blue-blue conversion element 14 has eight
normal directions.? Generate vibration. This mechanical movement is transmitted to the
incompressible fluid 21 and emitted as sound from the upper surface of the incompressible fluid
21. As described above, since the speaker of the present invention radiates through the JIII lk ?
incompressible fluid of the electric blue tatami conversion element, the type of fluid can be
selected to select characteristics, and the fluid upper surface can be selected. Can change the size
of the self-oscillation picture of the figure to 1 and produce an acoustic radiation. ???????
