[0018] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] refer to Figure 1-3The present invention provides a magnetic air duct earphone, comprising: an air duct earphone body 1, an earphone plug 2 and an earphone socket 3; the air duct earphone body 1 is connected to the earphone plug 2, the earphone plug 2 comprises an earphone plug shell 21 and a permanent magnet 22, the earphone plug shell 21 is inserted into the top of the earphone socket 3 with clearance fit and the end surface is flush, so as to ensure that it is tightly attracted to the earphone socket 3 after insertion without sound leakage; the permanent magnet 22 is embedded in the earphone plug shell 21, and the earphone permanent magnet 22 is a hollow circular ring structure to ensure a smooth sound transmission channel; a circuit board 7 is arranged in the earphone socket 3.

[0020] For further optimization, a connector 8 is provided at the bottom of the headphone socket 3, and the connector 8 is welded to the circuit board 7. The circuit board 7 obtains power supply and audio signals from the outside through the connector 8, and outputs audio signals.

[0021] Further optimization, the headphone socket 3 is made of metal that can be magnetically attracted, and the end faces of the headphone socket 3 and the headphone plug 2 are provided with magnetic attraction grooves with sound transmission holes, which facilitate the alignment and insertion of the headphone plug 2 and ensure stable magnetic attraction and unobstructed sound transmission channels.

[0022] The circuit board 7 includes an FPC circuit module 73, a magnetic sensor 71 and a sounding body 72; the magnetic sensor 71 is welded on the FPC circuit module 73, and the magnetic sensor 71 is assembled in the sensor groove of the headphone socket 3, and is used to detect whether the headphone plug 2 is inserted. The sensor groove is located at the rear of the magnetic attraction groove. When the headphone plug 2 is inserted into the magnetic attraction groove, a magnetic field change will be generated. The magnetic sensor 71 detects whether the headphone plug 2 is inserted by inducing the magnetic field change and transmits the detection signal to the FPC circuit module 73; the sounding body 72 is welded on the FPC circuit module 73 and installed in the groove of the sounding body 72 at the rear end of the headphone socket 3. There is a round hole in the middle of the groove of the sounding body 72, which forms a sound transmission cavity with the magnetic attraction groove at the front end. The rear end of the FPC circuit module 73 is welded with the connector 8, and the power supply and audio signal are obtained from the outside through the connector 8, and the audio signal is output.

[0023] After the FPC circuit module 73 is powered on, the magnetic sensor 71 connected to it detects in real time whether the headphone plug 2 is inserted. When the headphone is not detected to be inserted, the FPC circuit module 73 directly outputs the input audio signal to the outside through the connector 8; when the headphone is detected to be inserted, the FPC circuit module 73 transmits the input audio signal to the welded sounding body 72, and no longer outputs the audio signal through the connector 8, thereby realizing the automatic switching function; after receiving the audio signal, the sounding body 72 transmits the sound to the air duct earphone through the formed sound transmission channel, thereby realizing sound playback.

[0024] Further optimization, the rear end of the headphone socket 3 is a cylinder, which is convenient for drilling and installation. The headphone socket 3 and the mounting panel are fastened and installed by designing a thread or a retaining ring groove on the cylinder to cooperate with the fastener 6; the fastener 6 can be a retaining ring or a nut, which is used in conjunction with the headphone socket 3 according to specific needs.

[0025] Further optimization, a gasket 5 and a sealing ring 4 are arranged in sequence between the fastener 6 and the installation panel, the gasket 5 is in contact with the fastener 6, the bottom end of the sealing ring 4 is in close contact with the gasket 5, and the top end is in close contact with the installation panel. The function of the gasket 5 is to prevent the sealing ring 4 from deviating during installation.

[0026] When in use, the headphone plug 2 is inserted into the magnetic groove of the headphone socket 3. After insertion, the air duct headphone body 1, the headphone plug 2 and the headphone socket 3 form a relatively closed cavity, thereby realizing the conduction of sound wave signals.

[0027] The present invention provides a magnetic air duct earphone, which adopts a magnetic access method and has a simple structure, quick installation, small size, low cost, long service life, smooth sound transmission, and automatic audio switching. It solves the problem of poor contact of device interface caused by frequent plugging and unplugging of earphones, reduces the frequency of equipment maintenance, and improves convenience of use.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
