[0035] The embodiments of the present disclosure provide a touch device, an earphone device, and a mobile communication device. The preferred embodiments of the present disclosure are described below in conjunction with the drawings of the specification. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present disclosure, and are not used to limit the present disclosure. In addition, the embodiments and features in the embodiments of the present application can be combined with each other if there is no conflict.
[0036] The present disclosure provides a touch control device, which is applied to an electronic device. The touch control device is arranged in a touch control area of the electronic device, such as Figure 1 As shown, the touch device 10 includes: an excitation component 101 and a sensing component 102 that are arranged relatively spaced apart, and a controller (not shown in the figure) that is electrically connected to the excitation component 101 and / or the sensing component 102; and the excitation component 101 or the sensing component 102 is arranged adjacent to the inner side of the housing 104 of the touch area 103, so that when the touch area 103 is touched, the interval between the excitation component 101 and the sensing component 102 changes;
[0037] The excitation component 101 is used to generate an electromagnetic field through an excitation coil;
[0038] The induction component 102 is used to induce the electromagnetic field generated by the excitation component 101 to generate an induced electrical signal in the induction component 102;
[0039] The controller is used to detect the electrical signal in the component connected to it to determine the occurrence of touch and the type of touch; the electrical signal changes when the interval between the excitation component 101 and the sensing component 102 changes.
[0040] In the embodiment of the present disclosure, the touch device 10 is provided with an excitation component 101 to generate an electromagnetic field, and a sensing component 102 is provided to generate an induced electrical signal (e.g., current, voltage, impedance, etc.) under the action of the electromagnetic field, and the excitation component 101 and the sensing component 102 are arranged at a relative interval. When the touch area 103 does not receive a touch command, the interval between the excitation component 101 and the sensing component 102 is relatively stable, and the magnitude of the induced electrical signal in the sensing component 102 is also relatively stable. Once the touch area 103 is touched, the housing at the touch area 103 is slightly deformed, causing the excitation component 101 or the sensing component 102 to be displaced, and the interval between the two is changed (e.g., the interval is reduced or increased), thereby causing the electrical signals in the excitation component 101 and the sensing component 102 to change. The controller can determine the occurrence of a touch command and the type of touch by detecting the electrical signals.
[0041] Furthermore, the excitation component 101 and the induction component 102 need to be arranged relative to each other to ensure that the electromagnetic field of the excitation component 101 can pass through the induction component 102. In addition, since when the interval between the excitation component 101 and the induction component 102 changes, the internal electrical signals of both components may change, for example: the impedance, voltage, current, etc. in the excitation component 101, the current, voltage, etc. in the induction component 102, therefore, the controller can be electrically connected to the excitation component 101 and / or the induction component 102 as needed, so that the controller detects the electrical signals of the connected components. Furthermore, in order to change the interval between the excitation component 101 and the sensing component 102 when the touch area 103 receives a touch command, in one embodiment, the excitation component 101 or the sensing component 102 can be arranged adjacent to the touch area 103 on the inner side of the housing of the touch area 103: when the excitation component 101 is arranged adjacent to the housing 104 of the touch area 103, the touch operation triggers the excitation component 101 to move toward the sensing component 102, and when the sensing component 102 is arranged adjacent to the housing 104 of the touch area 103 (such as Figure 1 As shown, Figure 1 Taking the case 104 where the sensing component 102 is adjacent to the touch area 103 as an example, the touch operation triggers the sensing component 102 to move toward the excitation component 101 .
[0042] In another embodiment provided by the present disclosure, Figure 2a to Figure 2b As shown, the excitation component 101 includes at least one excitation coil 1011 and a first circuit board 1012 for carrying the excitation coil 1011; when the controller is electrically connected to the excitation component 101, the first circuit board 1012 also includes a first output circuit for outputting the electrical signal of the excitation coil 1011 to the controller.
[0043] In a possible implementation, the first circuit board 1012 includes a printed circuit board (PCB) and / or a flexible printed circuit board (FPC); the excitation coil 1011 is externally mounted on the first circuit board 1012 or etched on the first circuit board 1012 .
[0044] In the embodiment of the present disclosure, a first circuit board 1012 may be provided, and the excitation coil 1011 may be carried on the first circuit board 1012. In a possible implementation, the first circuit board 1012 may provide a power supply circuit, such as an oscillation circuit, for the excitation component 101. The oscillation signal may be transmitted to the excitation coil 1011 through a signal transmission device provided on the first circuit board 1012. In addition, when the controller is electrically connected to the excitation component 101, the first circuit board 1012 also includes a first output circuit for outputting the electrical signal of the excitation component 101. The first circuit board may be provided with a corresponding circuit structure to output the electrical signal of the excitation coil 1011 to the controller so that the controller detects the electrical signal of the excitation coil 1011. For example, the first output circuit may output the effective impedance generated by the excitation coil 1011 to the controller, or perform corresponding processing on the effective impedance and then transmit it to the controller. In a possible implementation, the controller may be provided on the first circuit board 1012.
[0045] Furthermore, the embodiments of the present disclosure do not limit the number of excitation coils 1011. When the number of excitation coils 1011 is greater than one, in one possible implementation, the electromagnetic fields generated by at least two excitation coils 1011 have the same magnetic field direction, so that a greater number of excitation coils 1011 generate a stronger electromagnetic field. In another possible implementation, the directions of the electromagnetic fields generated by at least two excitation coils 1011 may be different, so that the direction of the electromagnetic field generated by the excitation coil 1011 is the same as the direction of the electromagnetic field of at least one excitation coil 1011 with the strongest magnetic field strength.
[0046] like Figure 3 As shown, the excitation coil 1011 can be wound by a cable of corresponding material and exist independently on the outside of the first circuit board 1012, or it can be built into the inside of the first circuit board 1012 through an etching process.
[0047] In another embodiment provided by the present disclosure, continue to refer to Figure 2a to Figure 2bThe induction component 102 includes a metal conductor 1021, or includes at least one induction coil 1022 and a second circuit board 1023 for carrying the at least one induction coil 1022; when the controller is electrically connected to the induction component 102, the second circuit board 1023 includes a second output circuit for outputting the electrical signal of the induction coil 1022 to the controller.
[0048] In a possible implementation, the second circuit board 1023 includes a PCB and / or an FPC; the induction coil 1022 is externally mounted on the second circuit board 1023 or etched on the second circuit board 1023 .
[0049] In the embodiment of the present disclosure, in the case where the induction component 102 includes an induction coil 1022, a second circuit board 1023 may be provided, and the induction coil 1022 may be carried on the second circuit board 1023. According to actual needs, the first circuit board 1012 and the second circuit board 1023 may be the same circuit board or different circuit boards. In the case where the controller is electrically connected to the induction component 102, the second circuit board 1023 also includes a second output circuit for outputting the electrical signal of the induction coil 1022. The corresponding circuit structure may be provided on the second circuit board 1023 to output the electrical signal of the induction coil 1022 to the controller so that the controller detects the electrical signal of the induction coil 1022. For example, the second output circuit may output the oscillating voltage generated by the induction coil 1022 to the controller, or rectify, filter, amplify, etc. the oscillating voltage, and output the processed voltage or current to the controller. In a possible implementation, the controller may be provided on the second circuit board 1023.
[0050] like Figure 3 As shown, the induction coil 1022 can be wound by a cable of corresponding material and exist independently on the outside of the second circuit board 1023, or it can be built into the inside of the second circuit board 1023 through an etching process.
[0051] like Figure 2a As shown, the inductive component 102 includes a metal conductor 1021, such as Figure 2b As shown, the induction component 102 includes at least one induction coil 1022 and a second circuit board 1023 .
[0052] In another embodiment provided by the present disclosure, when the number of the induction coils 1022 is greater than one, at least two induction coils 1022 are sequentially arranged along the touch area (see Figure 3 ), and the electromagnetic field generated by the excitation component 101 covers the at least two induction coils 1022.
[0053] The number of induction coils 1022 is not limited in the embodiment of the present disclosure, and the number to be set can be determined according to the requirements and accuracy of different functions. When the number of induction coils 1022 is greater than one, more types of touch operations can be implemented. During implementation, at least two induction coils 1022 can be arranged in sequence along the long side of the long strip of the touch area 103.
[0054] In another embodiment provided by the present disclosure, Figure 4a-4b As shown, the excitation component 101 and the induction component 102 are arranged relatively spaced apart by the elastic insulating component 501 . Figure 4a The inductive component 102 is a metal conductor 1021. Figure 4b The inductive component 102 includes an inductive coil 1022 and a second circuit board 1023 .
[0055] In the embodiment of the present disclosure, in order to facilitate installation inside the electronic device, no object may be set between the excitation component 101 and the induction component 102, and only an interval may be set. Alternatively, an elastic insulating component 501 may be set between the excitation component 101 and the induction component 102, so that the excitation component 101 and the induction component 102 are connected through the elastic insulating component 501, such as foam. The elastic insulating component 501 has a certain elasticity. When receiving a touch command, the elastic insulating component 501 is squeezed and deformed, so that the interval between the excitation component 101 and the induction component 102 changes. After the trigger command ends, it can be restored to its original state, so that the excitation component 101 and the induction component 102 restore the original interval. The elastic insulating component 501 also needs to have an insulating property so as not to affect the electrical signals in the excitation component 101 and the induction component 102.
[0056] In another embodiment provided by the present disclosure, in view of the situation that the sensing component 102 includes at least two sensing coils 1022, and the controller is electrically connected to the sensing component 102, the controller is used to detect the electrical signals in the at least two sensing coils 1022; if the electrical signals in the at least two sensing coils 1022 change sequentially in a time sequence, the touch is determined to be sliding; and according to the order in which the electrical signals in the at least two sensing coils 1022 change, the sliding direction corresponding to the sliding is determined; if the electrical signals in the at least two sensing coils 1022 all change within a preset time interval, the touch is determined to be pressing; and according to the amplitude of the change in the electrical signals in the at least two sensing coils 1022, the pressing position of the pressing touch in the touch area 103 is determined;
[0057] In the case where the sensing component 102 includes an induction coil 1022 and the controller is electrically connected to the sensing component 102 , the controller is used to detect the electrical signal of the induction coil 1022 ; if a change in the electrical signal is detected, it is determined that the touch is a press.
[0058] In another embodiment provided by the present disclosure, in view of the situation that the excitation component 101 includes at least two excitation coils 1011, and the controller is electrically connected to the excitation component 101, the controller is used to detect the electrical signals in the at least two excitation coils 1011; if the electrical signals in the at least two excitation coils 1011 change sequentially in a time sequence, the touch is determined to be sliding; and according to the order in which the electrical signals in the at least two excitation coils change, the sliding direction corresponding to the sliding is determined; if the electrical signals in the at least two excitation coils 1011 change within a preset time interval, the touch is determined to be pressing; and according to the amplitude of the change in the electrical signals in the at least two excitation coils 1011, the pressing position of the pressing touch in the touch area 103 is determined;
[0059] In the case where the excitation component 101 includes an excitation coil 1011 and the controller is electrically connected to the excitation component 101, the controller is used to detect the electrical signal in the excitation coil 1011; if the electrical signal changes, it is determined that the touch is a press.
[0060] Taking the induction component 102 including two induction coils A and B as an example, the excitation current in the excitation coil arranged opposite to the induction component 102 generates an electromagnetic field, and the electromagnetic field covers the induction coils A and B, so that an induced current is generated in the induction coils A and B. Assuming that a sliding touch operation occurs, and the sliding direction is from the induction coil A to the induction coil B, due to the action of the force, the induction coil A and the induction coil B are successively close to the excitation coil, then in terms of time, the induction coil A first generates an induced voltage, and the induction coil B generates an induced voltage later. Similarly, if the sliding direction of the sliding touch is from the induction coil B to the induction coil A, the induction coil B first generates an induced voltage, and the induction coil A generates an induced voltage later. It can be seen that if the controller detects that the electrical signals of the induction coil A and the induction coil B change successively, and the order of change, it can determine that the sliding touch occurs and the sliding direction.
[0061] From the above example, we can see that the number of induction coils and the density of their arrangement can affect the accuracy and sensitivity of detection. When the number of induction coils is large and the arrangement is dense, the accuracy and sensitivity of detection will become higher.
[0062] like Figure 6As shown, in the case of a press touch, due to one press (or tap) the touch area 103 is subjected to force once, the induction coil A and the induction coil B will be close to the excitation coil within a smaller preset time interval (the preset time interval here is smaller, can be set to millisecond level, or can be approximately simultaneous), and then both generate induced voltages within the preset time interval. It can be seen that if the controller detects that both the induction coil A and the induction coil B generate induced voltages within a smaller preset time interval, it can be determined that a press touch instruction has been received. In addition, due to the different locations where the press or tap occurs, the amplitude of the change in the electrical signal in the induction coil A and the induction coil B is different ( Figure 6 The closer the distance to the position where the pressing or tapping occurs, the greater the deformation of the touch area 103, the smaller the interval between the excitation coil, and the greater the change amplitude of the internal electrical signal. On the contrary, the farther the distance from the position where the touch command is pressed, the smaller the deformation of the touch area 103, the larger the interval between the excitation coil, and the smaller the change amplitude of the internal electrical signal. It can be seen that the amplitude of the change of the electrical signal has a certain proportional relationship with the pressing or tapping position. Therefore, the pressing or tapping position in the touch area 103 can be determined according to the amplitude of the change of the electrical signal in the induction coil A and the induction coil B (for example: the difference or ratio of the electrical signal in the induction coil A and the induction coil B, etc.). If the pressed position is in the middle of the induction coil A and the induction coil B, the amplitude of the change of the electrical signal in the induction coil A and the induction coil B is the same.
[0063] The case where the excitation component 101 includes two excitation coils 1011, and the controller is electrically connected to the excitation component 101, is similar to the case where the induction component 102 includes two induction coils A and B, and the controller is electrically connected to the induction component 102 for electrical signal detection in the above example, and will not be repeated here. It can be seen that whether it is the induction component 102 or the excitation component 101, by setting at least two corresponding coils and allowing the controller to detect the electrical signals of the corresponding coils, it is possible to detect sliding touch (including: identifying sliding operations, sliding directions, etc.), and it is also possible to detect pressing touch (including: identifying pressing operations, the location where pressing occurs, etc.).
[0064] In the case where the sensing component 102 includes an induction coil 1022 and the controller is electrically connected to the sensing component 102, or the excitation component 101 includes an excitation coil 1011 and the controller is electrically connected to the excitation component 101, the controller can detect the electrical signal in the corresponding component; if the electrical signal changes, it is determined that the received touch command is a press touch command.
