[0023] In order to make the objects, features and advantages of the present application more obvious and understandable, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0024] The inventors have found through analyzing the prior art that telephones, especially landline telephones, may be interfered with during calls, resulting in poor call quality. The filter circuits currently involved in telephones are in operation regardless of whether the call is in progress or after the call is hung up, which will affect the service life of the filter circuit or filter for a long time.

[0025] Reference Figure 1 and Figure 2 , respectively showing a schematic diagram of the structure of an anti-interference telephone in two states provided in an embodiment of the present application, including a telephone body 1 and a microphone 2;

[0026] The microphone 2 includes a transmitter 202, a receiver 201 and an elastic mechanism, and the elastic mechanism is fixedly connected to the receiver 201;

[0027] The telephone body 1 includes an on-hook switch 101 and a magnetic mechanism, wherein the magnetic mechanism is disposed in the on-hook switch 101 and is magnetically coupled to one end of the receiver 201; a moving contact 203 is disposed at the other end of the receiver 201, a fixed contact 204 is disposed in the microphone 2 corresponding to the moving contact 203, and a filter 205 is electrically connected between the fixed contact 204 and the transmitter 202;

[0028] When the magnetic effect between the receiver 201 and the magnetic mechanism disappears, the elastic mechanism drives the moving contact 203 of the receiver 201 to connect with the fixed contact 204, and enables the filter 205 to conduct and work.

[0029] In the embodiment of the present application, in contrast to the problem in the prior art that the filter of a telephone is always in working state, which affects its service life, the present application provides a solution that the filter works only when a call is made, specifically: comprising a telephone body 1 and a microphone 2, the microphone 2 comprising a transmitter 202, a receiver 201 and an elastic mechanism, the elastic mechanism being fixedly connected to the receiver 201; the telephone body 1 comprising an on-hook switch 101 and a magnetic mechanism, the magnetic mechanism being arranged in the on-hook switch 101 and magnetically coupled to one end of the receiver 201; a moving contact 203 being arranged at the other end of the receiver 201, a fixed contact 204 being arranged in the microphone 2 corresponding to the moving contact 203, a filter 205 being electrically connected between the fixed contact 204 and the transmitter 202; when the magnetic effect between the receiver 201 and the magnetic mechanism disappears, the elastic mechanism drives the moving contact 203 of the receiver 201 to connect with the fixed contact 204, and enables the filter 205 to conduct and work. By providing the elastic mechanism and the magnetic mechanism, the filter 205 can be kept working when the phone is connected, thereby suppressing interference during the call, and the filter 205 can be kept disconnected when the phone is hung up, thereby increasing the service life of the filter 205.

[0030] Next, a telephone in each exemplary embodiment of the present application will be further described.

[0031] In this embodiment, the magnetic mechanism includes a first magnet 102 embedded in the on-hook switch 101. The receiver 201 is movably arranged. When the phone is hung up, the receiver 201 can generate magnetic coupling with the first magnet 102 due to the inherent magnetic coils of the transmitter 202 and the receiver 201, so as to separate the moving contact 203 from the fixed contact 204, and thus disconnect the filter 205.

[0032] In this embodiment, the elastic mechanism includes a guide column 206, a spring 207 and a fixed block 208, one end of the guide column 206 is connected to the fixed block 208, one end of the spring 207 passes through the guide column 206 and abuts against the fixed block 208; the side of the receiver 201 is provided with a connecting block passing through the guide column 206, and the connecting block abuts against the other end of the spring 207.

[0033] It should be noted that the elastic direction of the spring 207 corresponds to the magnetic direction of the first magnet 102. When the microphone 2 is lifted, the magnetic effect of the first magnet 102 disappears, and the receiver 201 moves toward the fixed contact 204 under the elastic action of the spring 207. The guide column 206 plays a guiding role, so that the moving contact 203 is connected to the fixed contact 204.

[0034] In this embodiment, there are at least two elastic mechanisms.

[0035] It should be noted that the plurality of elastic mechanisms are distributed in an array along the center of the receiver 201 , so that the receiver 201 can move smoothly.

[0036] In this embodiment, the movable contact 203 is in a convex shape, and the fixed contact 204 is in a concave shape. The concave-convex structure allows the movable contact 203 and the fixed contact 204 to be connected more firmly.

[0037] In this embodiment, the magnetic attraction of the magnetic mechanism is greater than the elastic force of the elastic mechanism. The magnetic attraction of the magnetic mechanism is greater than the elastic force of the elastic mechanism to ensure that the moving contact 203 and the fixed contact 204 remain separated when the phone is hung up.

[0038] In this embodiment, the telephone body 1 is further provided with a second magnet 103 magnetically coupled to the microphone 202, and the microphone 202 is provided with a magnetic ring. The first magnet 102 and the second magnet 103 are magnetically attracted to the receiver 201 and the microphone 202 respectively, so that the microphone 2 can be firmly fixed on the telephone body 1 after the call is hung up.

[0039] In this embodiment, the microphone 2 is further provided with a filter indicator light 209 electrically connected to the filter 205 .

[0040] It should be noted that when the filter 205 starts to work, the user can know through the filter indicator light 209 that the call process is in the anti-interference state.

[0041] Although the preferred embodiments of the present application have been described, those skilled in the art may make additional changes and modifications to these embodiments once they have learned the basic creative concept. Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications that fall within the scope of the embodiments of the present application.

[0042] Finally, it should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or terminal device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or terminal device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the existence of other identical elements in the process, method, article or terminal device including the elements.
