[0024] The present application is further described in detail below in conjunction with the accompanying drawings and implementation methods. It is to be understood that the specific implementation methods described herein are only used to explain the relevant utility model, rather than to limit the utility model. It should also be noted that, for ease of description, only the parts related to the relevant utility model are shown in the accompanying drawings. In addition, there are cases where the same elements are marked with the same symbols and repeated descriptions are omitted. In addition, there are cases where repeated descriptions are omitted for elements with the same or corresponding functions and structures.

[0025] In an earphone device having two left and right earphones that can be physically completely separated, magnets, such as permanent magnets, are mounted on the left and right earphones, so that when taking out the earphones from the earphone box, one earphone is taken by hand, and the other earphone can follow the taken earphone due to the magnetic force between the magnets and be taken out from the earphone box together. In this way, it is convenient to take out the earphones. In addition, the two earphones taken out of the earphone box are easy to fall or lose when they are scattered when not in use, but the two earphones can be connected together by the magnetic force between the magnets mounted on the two earphones, thereby preventing the problem of a single earphone being easy to fall due to its small size, and preventing the problem of a single earphone being lost or difficult to find.

[0026] However, in conventional headphone devices that use magnetic force between magnets to connect left and right earphones, in order to reliably connect the two earphones by magnetic force, at least two magnets need to be mounted on each earphone, which results in a high cost.

[0027] With regard to the problem of high cost of such earphone devices, the inventors of the present invention have discovered through research that by replacing one magnet on each of the two earphones with a magnetic body such as an iron plate, a magnetic body cheaper than a permanent magnet can be used, thereby reducing costs.

[0028] Figure 1 FIG. 1 is a schematic top view of a main substrate of the headphone device according to the embodiment. Figure 2FIG. 1 is a schematic plan view schematically showing a state in which two earphones of the earphone device according to the embodiment are magnetically connected.

[0029] like Figure 1 As shown, the earphone device 100 includes a first earphone 110 and a second earphone 120. The first earphone 110 includes a magnet 111, a magnetic body 112, and a main substrate 113. The magnet 111 and the magnetic body 112 may be disposed on the housing of the earphone, may be disposed inside the housing of the earphone, may be disposed on the main substrate, etc., and there is no particular limitation on the specific location of the magnet 111 and the magnetic body 112, as long as the function of connecting to another earphone by magnetic force can be achieved. The second earphone 120 includes a magnet 121, a magnetic body 122, and a main substrate 123. Similarly, there is no particular limitation on the location of the magnet 121 and the magnetic body 122, as long as the function of connecting to another earphone by magnetic force can be achieved, for example, they may be disposed on the housing of the earphone, may be disposed inside the housing of the earphone, may be disposed on the main substrate, etc.

[0030] In this embodiment, if Figure 2 As shown, preferably, when the magnetic body 112 of the first earphone 110 and the magnet 121 of the second earphone 120 are connected by magnetic force, the magnet 111 of the first earphone 110 and the magnetic body 122 of the second earphone 120 are arranged at a position where they can be connected by magnetic force.

[0031] By arranging the positions of the magnet 111 and the magnetic body 112 in the first earphone 110 and the magnet 121 and the magnetic body 122 in the second earphone 120 in this way, the first earphone 110 and the second earphone 120 can be reliably connected (magnetically connected) together by the magnetic attraction between the magnet 111 and the magnetic body 122, and the magnetic attraction between the magnet 121 and the magnetic body 112. As a result, a magnetic body cheaper than a permanent magnet can be used, and the cost of the earphone device can be reduced.

[0032] In addition, in the present embodiment, the earphone device 100 may further include a case (not shown) capable of housing the first earphone 110 and the second earphone 120. In this case, preferably, when the first earphone 110 and the second earphone 120 are housed in the case, the magnetic body 112 of the first earphone 110 and the magnet 121 of the second earphone 120 are arranged at opposing positions, and the magnet 111 of the first earphone 110 and the magnetic body 122 of the second earphone 120 are arranged at opposing positions.

[0033] Thus, when taking out the earphone from the box, if one of the first earphone 110 and the second earphone 120 is taken out by hand, the other earphone can be taken out of the box together with the taken earphone due to the magnetic attraction between the magnet and the magnetic body, so that the earphone can be taken out of the box conveniently.

[0034] In addition, in this embodiment, if Figure 1 As shown in , the first earphone 110 may further include a magnetic sensor 114, and the second earphone 120 may further include a magnetic sensor 124. It should be noted that in this embodiment, it is sufficient that at least one of the first earphone 110 and the second earphone 120 includes a magnetic sensor.

[0035] In the present embodiment, the magnetic sensor 114 and / or the magnetic sensor 124 is preferably a magnetic sensor whose output signal changes with changes in the external magnetic field.

[0036] Figure 3 FIG. 1 is a schematic diagram of a simulation schematically showing a magnetic field when two earphones of the earphone device according to the embodiment are magnetically connected. Figure 4 FIG. 1 is a schematic diagram of a simulation schematically showing the magnetic field of a single earphone of the earphone device according to the embodiment.

[0037] like Figure 3 , Figure 4 As shown, the direction of the magnetic field generated by the magnet and the density of the magnetic lines of force are different when the earphones are connected to the magnetic body (magnetically connected) and when they are not connected to the magnetic body. Therefore, by configuring a magnetic sensor whose output signal changes with changes in the external magnetic field, it is possible to detect whether the two earphones are magnetically connected. For example, the magnetic sensor 114 and / or the magnetic sensor 124 can detect whether the first earphone 110 and the second earphone 120 are magnetically connected by detecting magnetic induction intensity, magnetic flux, magnetic field intensity, magnetic field direction, magnetic resistance, etc.

[0038] In the present embodiment, it is preferred that the magnetic sensor 114 and / or the magnetic sensor 124 is a magnetic sensor that outputs a signal change when the first earphone 110 and the second earphone 120 are magnetically connected. For example, the magnetic sensor 114 and / or the magnetic sensor 124 may be an AMR sensor, a TMR sensor, a GMR sensor, a Hall element, etc. In addition, in the present embodiment, the magnetic sensor 114 and / or the magnetic sensor 124 may function as a magnetic switch, outputting a low signal when the first earphone 110 and the second earphone 120 are not magnetically connected, and outputting a high signal when the first earphone 110 and the second earphone 120 are magnetically connected.

[0039] Furthermore, in the present embodiment, it is preferable that the magnetic sensor 114 and / or the magnetic sensor 124 is a magnetic sensor that outputs a signal change by detecting a change in the direction of an external magnetic field.

[0040] In the present embodiment, in the first earphone 110 having the magnetic sensor 114, the magnetic sensor 114 is preferably arranged at a position closer to the inside of the first earphone 110 than an imaginary line connecting the center of the magnetic body 112 and the center of the magnet 111. By arranging the magnetic sensor 114 in this way, the magnetic connection between the first earphone 110 and the second earphone 120 can be effectively detected.

[0041] In the first earphone 110 having the magnetic sensor 114, the magnetic sensor 114 is preferably disposed near the center between the magnetic body 112 and the magnet 111 in a direction connecting the centers of the magnetic body 112 and the magnet 111. Thus, the magnetic connection between the first earphone 110 and the second earphone 120 can be effectively detected.

[0042] Furthermore, it should be noted that, in the first earphone 110 having the magnetic sensor 114, when the magnetic sensor 114 is arranged at a position closer to the inside of the first earphone 110 than an imaginary line connecting the center of the magnetic body 112 and the center of the magnet 111, and is arranged near the middle between the magnetic body 112 and the magnet 111 in the direction connecting the centers of the magnetic body 112 and the magnet 111, the magnetic connection between the first earphone 110 and the second earphone 120 can be further effectively detected, which is further preferred.

[0043] Similarly, in the second earphone 120 having the magnetic sensor 124, the magnetic sensor 124 is preferably arranged at a position closer to the inside of the second earphone 120 than the imaginary line connecting the center of the magnetic body 122 and the center of the magnet 121. In addition, it is preferred that the magnetic sensor 124 is arranged near the center between the magnetic body 122 and the magnet 121 in the direction connecting the centers of the magnetic body 122 and the magnet 121. In addition, it is further preferred that the magnetic sensor 124 is arranged at a position closer to the inside of the second earphone 120 than the imaginary line connecting the center of the magnetic body 122 and the center of the magnet 121, and is arranged near the center between the magnetic body 122 and the magnet 121 in the direction connecting the centers of the magnetic body 122 and the magnet 121.

[0044] In addition, in the present embodiment, at least one of the first earphone 110 and the second earphone 120 may further include a control unit (not shown). The control unit includes, for example, a CPU (central processing unit) and a memory. The control unit may also include a dedicated integrated circuit, etc. The control unit is connected to the magnetic sensor so as to be able to receive a detection signal transmitted from the magnetic sensor, and the control unit can detect the magnetic connection between the first earphone 110 and the second earphone 120 based on the received detection signal. For example, when the detection signal received from the magnetic sensor is a low signal, the control unit determines that the first earphone 110 and the second earphone 120 are not magnetically connected, and when the detection signal received from the magnetic sensor is a high signal, the control unit determines that the first earphone 110 and the second earphone 120 are magnetically connected.

[0045] It should be noted that either one of the first earphone 110 and the second earphone 120 may include a control unit, or each of the first earphone 110 and the second earphone 120 may include a control unit. In addition, the control unit of the first earphone 110 may receive a detection signal from the magnetic sensor 114 of the first earphone 110, or may receive a detection signal from the magnetic sensor 124 of the second earphone 120. In other words, the control unit and the magnetic sensor may both be configured in one earphone, or may be configured in different earphones.

[0046] When the control unit detects that the first earphone 110 and the second earphone 120 are magnetically connected based on the detection signal transmitted from the magnetic sensor, for example, control can be performed so that the first earphone 110 and the second earphone 120 no longer continue to discharge, thereby avoiding the first earphone 110 and the second earphone 120 from continuously discharging and reducing the charge amount when not in use.

[0047] In addition, in this embodiment, the first earphone 110 and the second earphone 120 are wireless earphones that can be physically separated from each other. In other words, the earphone device 100 can be a wireless earphone device that can be physically separated from the first earphone 110 and the second earphone 120.

[0048] In addition, in the present embodiment, the earphone device 100 may be a wired earphone that transmits audio signals through a cable or the like, or a wireless earphone that transmits audio signals wirelessly through a physical connection between the first earphone 110 and the second earphone 120 through a cable or the like. In these cases, by magnetically connecting the first earphone 110 and the second earphone 120 of the above structure, it is also possible to facilitate carrying or storing the earphone device. In addition, when the earphone device 100 is provided with the above control unit, it is also possible to prevent the first earphone 110 and the second earphone 120 from being continuously discharged and the charge amount from being reduced when not in use.

[0049] It should be noted that, in the above description, the case where the first earphone 110 and the second earphone 120 respectively have one magnetic body and one magnet is used as an example for explanation, but the first earphone 110 and the second earphone 120 may respectively have two or more magnetic bodies and two or more magnets. In this case, when the two or more magnetic bodies of the first earphone 110 and the two or more magnets of the second earphone 120 are connected by magnetic force, the two or more magnets of the first earphone 110 and the two or more magnetic bodies of the second earphone 120 may be arranged at positions where they can be connected by magnetic force.

[0050] Therefore, through the connection between the magnet and the magnetic body, it is also possible to achieve the purpose of reducing costs by using a magnetic body that is cheaper than a permanent magnet, and the connection reliability of the two earphones can be further improved.

[0051] When the first earphone 110 has two or more magnetic bodies and two or more magnets, the magnetic sensor 114 can be arranged near the middle between the two or more magnetic bodies and the magnets in a direction connecting the centers of the closest pair of magnetic bodies and the magnets.

[0052] In addition, it should be noted that the first earphone 110 may also include more than one magnetic sensor, and the second earphone 120 may also include more than one magnetic sensor.

[0053] In addition, it should be noted that iron, nickel, cobalt, and alloys thereof can be used as the material of the magnetic body.
