Embodiment Construction

[0022] see figure 1 As shown, the sensor 1 of the present invention includes a magnetic field generator 11 for transmitting encoded information based on magnetic field induction; a magnetic field inductor 12 independent of the magnetic field generator for transmitting encoded information based on magnetic field induction The encoded information is received. Among them, the magnetic field generator 11 achieves the technical effect of generating a larger magnetic field strength by using high magnetic moment materials as the inner core of the current-carrying coil, increasing the electromagnetic induction current or the number of wire turns, or increasing the volume of the permanent magnet, etc. . The inner core of the current-carrying coil of the magnetic field generator 11 can be made of soft magnetic material, such as high magnetic moment material such as NiFe, CoNiFe or CoFe. In some specific applications, many systems or devices have their own speakers, and the speakers of...

Abstract

The invention discloses a sensor for sending and receiving the encoded information based on magnetic field induction. The sensor includes at least one magnetic field generator for the sending of the encoded information based on magnetic field induction, at least one magnetic field induction apparatus independent from the magnetic field generator for the receiving of the encoded information based on magnetic field induction. By the design, the magnetic field sensor can respectively optimize the magnetic field generator and the magnetic field induction apparatus to achieve optimum sending and receiving. The invention also discloses an electronic product which has a memorizer, wherein the electronic product is provided with the magnetic induction communication sensor of the invention which can send and receive information through magnetic field between users.

Description

technical field [0001] The invention relates to a sensor, especially a communication sensor based on magnetic field induction, and also relates to the application of the sensor. Background technique [0002] In today's society, wireless communication technology is more and more widely used, such as the technology of transmitting and receiving signals through radio frequency (RF), including existing wireless communication equipment, such as mobile phones, etc. Transmit and receive wireless signals. However, RF technology requires complex communication lines and sufficient current supply, and its complex structure increases the volume and weight of communication equipment. [0003] On the other hand, RF has the characteristics of a small attenuation period, which ensures that it can be transmitted over a long distance. Because of its long transmission distance, it is easy to be shared and interfered with by other electromagnetic devices in the process of transmission or rece...
