Embodiment Construction

[0008] The natural frequency of a C-shaped magnet is related to its mass, elasticity, magnetism and other factors. It can be made of giant magnetostrictive material (GMM) (this material has the characteristics that the magnetization and stress generation effects occur almost simultaneously), every A C-shaped magnet has a different natural frequency f (this different natural frequency can be reflected by adjusting the quality of the two poles of the C-shaped magnet), and a system is composed of many such C-shaped magnets. When the sound wave of the natural frequency f enters the system , the C-shaped magnet whose natural frequency is f in the system produces strong vibrations. If polyphony of various frequencies is introduced into the system, many C-shaped magnets will vibrate strongly, and the system can feel the polyphony separately. Part.

[0009] Since the human ear cannot hear ultrasonic waves above 20,000 Hz, the vibration frequency of the C-type magnet should be higher t...

Abstract

The invention relates to the field of image transmission and receiving devices, in particular to a device for transmitting and receiving images by using electromagnetic waves. According to the method, an image is converted into sound waves, and the purpose of integrally transmitting and integrally receiving the image by a plurality of pixel points is achieved by utilizing the characteristic that the sound waves do not interfere with one another in the propagation process. An image acquisition system is used for dividing an image into a plurality of pixel points, the pixel points are converted into electric signals point by point, then the electric signals are converted into vibration (namely sound wave signals) through an image transmission device, and the characteristic that sound waves do not interfere with one another in the propagation process is used for detecting vibration. And the sound wave signals are integrally transmitted out by radio waves through a radio transmitting device, are integrally received by a radio and are respectively converted into electric signals of each pixel point by an image receiving device, and then the electric signals form an image through a display. The device has the characteristics of high working efficiency and capability of reducing the carrier frequency, and can be used in various fields of image transmission and receiving.

Description

technical field [0001] The invention relates to the field of image transmission and reception devices, in particular to a device for transmitting and receiving images by using electromagnetic waves. Background technique [0002] The device that uses electromagnetic waves to transmit and receive images currently on the market is: first divide an image into several pixel points, convert them into electrical signals point by point, and then use radio waves to transmit these electrical signals point by point in sequence, so that This results in the disadvantages of high carrier frequency, short propagation distance and low efficiency. Contents of the invention [0003] In order to solve the above problems, the present invention designs a device that converts the pixels of an image into sound waves, and then uses the characteristics of sound waves not interfering with each other in the propagation process to achieve the purpose of overall transmission and overall reception of m...
