It will be appreciated that the first coil 301 is electrically connected to the first circuit board 2011 in the first earpiece 201, enabling conversion of electrical signals in the first circuit board 2011 to magnetic signals. The first earphone 201 may further include a first main board electrically connected to the first circuit board 2011, so that an electrical signal of the first main board is transmitted to the first circuit board 2011, and then converted into a magnetic signal by the first coil 301. For the main board of the headphone, the main board may be disposed in both the first headphone 201 and the second headphone 202, or of course, the main board may be disposed in only one of the first headphone 201 or the second headphone 202, a coil in the headphone may be connected to the main board, or may be connected to a circuit board in the headphone for implementing other functions, and a coil in the other headphone is connected to a circuit board in the headphone for implementing other functions, for example, the first headphone 201 includes a first main board, and the first main board is electrically connected to the first circuit board 2011; the second earphone 202 comprises a second circuit board 2022, to which the second coil 302 is electrically connected, and the second circuit board 3022.

The magnetic conductive material strip 400 may be fixed to and penetrate the first coil 301 and the second coil 303, or may be fixedly connected to the headband 100, which is not particularly limited herein. The magnetic conductive material strip 400 is shown in phantom in fig. 1 in positional relationship to the headband 100. the magnetic conductive material strip 400 may be a strip-like structure that occupies some space. In the headset provided in this embodiment, the process of information transmission between the first earphone 201 and the second earphone 202 may be as follows: if there is an electrical signal that needs to be transmitted to another single earphone in any one of the first earphone 201 and the second earphone 202, the electrical signal is converted into a magnetic signal by using an alternating magnetic field generated by a coil connected to a circuit board therein, that is, the magnetic signal is induced to the magnetic conductive material strip 400, the magnetic signal is transmitted to a coil connected to a circuit board in another single earphone through the magnetic conductive material, and the magnetic signal is converted into an electrical signal by the coil, so that the electrical signal transmitted from the opposite side is received. In the above process, the information transmitted from the first earphone 201 to the second earphone 202 is subjected to the electrical/magnetic conversion, and then the information is transmitted through the magnetic/electrical conversion.

The headphone that this application embodiment provided carries out the information interaction through magnetic signal between first earphone and the second earphone, utilizes the alternating magnetic field that the coil of one side produced, with electric signal induction to magnetic material, converts magnetic signal into promptly, transmits this magnetic signal to the coil of opposite side through magnetic material, and the coil converts this magnetic signal into electric signal again, realizes receiving the electric signal that offside transmission came. Because the digital signals are transmitted in the form of magnetic signals in the magnetic conductive material, mutual crosstalk cannot be generated, the problems of noise, crosstalk and other electrical properties are solved, and the reliability is high. Because the cross section of the magnetic conductive material strip is smaller than that of the signal wires, the space of the head band can be saved. In addition, the speed of information transmission of the magnetic conductive material is close to that of electromagnetic waves, and high-speed transmission can be realized.

s103: the magnetically permeable material strip transmits the first magnetic signal to a second coil;
s104: the second earpiece receives the first magnetic signal through the second coil.
In a specific implementation, if the first earphone 201 needs to transmit the magnetic signal a1, the first end of the magnetic conductive material strip 400 transmits the magnetic signal a1 output by the first coil 301 to the second earphone 202, the first earphone 201 may transmit the electrical signal a1 to the first coil 301, the first coil 301 converts the electrical signal a1 into the magnetic signal a2 and induces the magnetic signal a2 to the first end of the magnetic conductive material strip 400, and the first end of the magnetic conductive material strip 400 transmits the magnetic signal a2 output by the first coil 301 to the second end of the magnetic conductive material strip 400; the second coil 302 receives the magnetic signal a2 output from the second end of the magnetic material strip 400, and the second coil 302 converts the magnetic signal a2 into an electrical signal a1, which can transmit the electrical signal a1 to the second earphone 202.
It should be noted that the first magnetic signal in this embodiment may include N signal channels, and may include an audio signal channel, a control signal channel, a voltage signal channel, and the like, where the audio signal channel is used for transmitting an audio signal between the first earphone 201 and the second earphone 202, and the control signal channel is used for transmitting a control signal between the first earphone 201 and the second earphone 202, such as a control signal generated by a key on one of the earphones, and the control signal is transmitted in the form of an approximate pulse in the magnetic conductive material strip 400. The voltage signal path is used for transmitting voltage signals between the first earphone 201 and the second earphone 202. The signals may be in the form of digital signals or analog signals, and the multiple signal paths may be implemented using time division multiplexing or frequency division multiplexing. Because a plurality of signal channels can not generate mutual crosstalk when propagating in the magnetic conduction material strip 400, the problems of noise, crosstalk and other electrical properties caused by different signal lines in the related technology are solved.
It can be understood that the main board in the headset may be disposed in the second headset, that is, the second headset includes the second main board, and a process of the second headset sending a message to the first headset is shown in fig. 8, and specifically includes the following steps:
s201: the second earphone acquires a second magnetic signal;
preferably, the present step comprises: the second earphone converts an internal electrical signal into the second magnetic signal, or receives the second magnetic signal from the outside.
S202: the second earpiece transmits the second magnetic signal to the strip of magnetically permeable material via a second coil;
s203: the magnetically permeable material strip transmits the second magnetic signal to the first coil;
s204: the first earpiece receives the second magnetic signal through the first coil.
According to the information transmission method provided by the embodiment of the application, information interaction is carried out between the first earphone and the second earphone through the magnetic signals, the electric signals are induced to the magnetic conductive material by the aid of the alternating magnetic field generated by the coil on one side, namely, the electric signals are converted into the magnetic signals, the magnetic signals are transmitted to the coil on the other side through the magnetic conductive material, and then the magnetic signals are converted into the electric signals by the coil, so that the electric signals transmitted from the opposite side are received. Because the digital signals are transmitted in the form of magnetic signals in the magnetic conductive material, mutual crosstalk cannot be generated, the problems of noise, crosstalk and other electrical properties are solved, and the reliability is high. Because the cross section of the magnetic conductive material strip is smaller than that of the signal wires, the space of the head band can be saved. In addition, the speed of information transmission of the magnetic conductive material is close to that of electromagnetic waves, and high-speed transmission can be realized.
In another exemplary embodiment, there is also provided a computer readable storage medium comprising program instructions which, when executed by a processor, implement the steps of the above-described information transmission method, the program instructions being executable by the processor of the headset to perform the above-described information transmission method.
