Title: Submerged loudspeaker device
Inventor: WADA RYOICHI
IPC: H04R1/44
Filed: 1987-08-25
Abstract: PURPOSE:To eliminate the need of an oscillating board and to miniaturize the titled device by providing a coil for supplying a fixed magnetic field to a specific area in water and an electromagnet to allow an electroacoustic signal to flow to the above-mentioned specific area in the water in a direction perpendicular to the magnetic field. CONSTITUTION:By impressing a direct voltage to A-A' terminals, the magnetic field is formed in the vertical direction in an oscillation space 4. A magnetic core material 1 is used for conducting a magnetic flux except the oscillation space. Here, when the electroacoustic signal is impressed to both edges B-B' of an electrode 3, the current flows in a horizontal direction in the water in the oscillation space. At such a time, since the vertical magnetic field exists in the oscillation space, force is generated in the direction perpendicular to the paper surface of a figure, and as a result, the water in the oscillation space 4 is moved. Consequently, an electric signal impressed to the electrode 3 is converted to the force to directly move the water, and it is converted to the oscillation of the water in the oscillation space, namely, a submerged sound wave.
