[0023] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0024] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0025] The present application describes a handheld device. The handheld device may be a stylus. The stylus may be a ballpoint pen, pencil, fountain pen, touch screen pen, or other pen that can be held by a user. Of course, it may also be other types of pens, which will not be described in detail here. The handheld device may also be some equipment that requires the user to maintain a certain holding posture before use.

[0026] Next, the handheld device is taken as an example to explain.

[0027] See also Figure 1 , Figure 1 Schematic diagram of the structure of the handheld device 100 in some embodiments of the present application. The handheld device 100 may include a body 10, a functional part 20 arranged on the body 10, a positive line 30 arranged on the surface of the body 10, a negative line 40 arranged on the surface of the body 10, and a power module 50 matched with the positive line 30 and the negative line 40. The body 10 can be held by a user. The functional part 20 may have functions such as writing, poking, knocking or hitting, and of course, it may also have functions matching the handheld device 100, which will not be repeated. The user can manipulate the functional part 20 while holding the body 10 to realize the function of the functional part 20. The power module 50 can provide a pulse current. The positive line 30 and the negative line 40 are electrically connected to the power module 50 respectively. When the positive line 30 and the negative line 40 are turned on, a pulse current can flow. When the user holds the main body 10, the positive wire 30 and the negative wire 40 can be touched at the same time, so that the user acts as a conductor connecting the positive wire 30 and the negative wire 40, and then a pulse current will flow through the user, causing muscle contraction or relaxation through the pulse current, simulating the effect of mechanical force on a person, causing the user to vibrate, or feel the touch of being hammered, knocked, rubbed, etc., thereby achieving the effect of reminding the user.

[0028] See also Figure 1 The surface of the body 10 has a gripping area 101 and a touch limiting area 102. The gripping area 101 can be gripped by a user.

The touch limit area 102 can be provided with the positive line 30 and the negative line 40, and then the user is reminded of the limit through the cooperation of the positive line 30 and the negative line 40. Of course, the touch limit area 102 can also be held by the user. The user can hold the body 10 by holding the holding area 101 or the touch limit area 102.

[0029] The main body 10 can correct the user's holding posture and standardize the user's holding posture through the cooperation of the holding area 101 and the touch limit area 102. In some scenarios, the user can hold the holding area 101 to use the handheld device 100. When the main body 10 is not held properly, the touch limit area 102 will be touched, thereby connecting the positive line 30 and the negative line 40, so that the pulse current flows through the user, and the pulse current makes the user feel tactile to remind the user. In some scenarios, the user can hold the touch limit area 102 to use the handheld device 100, thereby connecting the positive line 30 and the negative line 40, so that the pulse current flows through the user, and the pulse current makes the user feel tactile to remind the user to hold the posture properly. In some scenarios, the user can hold the touch limit area 102 to use the handheld device 100, thereby connecting the positive line 30 and the negative line 40. After the user holds the device for a preset period of time, the power module 50 provides a pulse current so that the pulse current flows through the user, and the pulse current makes the user feel tactile, so as to remind the user of the holding time.

[0030] The functional part 20 can be a writing part for writing, or a touch part for touching, or a part with other functions, which will not be described in detail. The functional part 20 can be directly fixed and installed on the body 10.

[0038] See also Figure 1 The power module 50 can be a pulse power supply, a pulse current generator, or other devices that can generate pulse current. The power module 50 can be arranged in the body 10, or it can be an external device, and then arranged outside the body 10, and is electrically connected to the positive line 30 and the negative line 40.

[0039] See also Fig.10 , Fig.10 for Figure 2 The schematic diagram of the structure of the positive line 30 and the negative line 40 in the embodiment shown, and the power module 50 in other embodiments. The power module 50 may include a first power component 51 for outputting pulse current, a second power component 52 for outputting detection current, a current sensor 53 matched with the second power component 52, and a power controller 54 electrically connected to the first power component 51 and the current sensor 53 respectively.

[0040] The first power supply component 51 is electrically connected to the positive line 30 and the negative line 40, respectively, to output pulse current to the positive line 30 and the negative line 40. In some embodiments, the first power supply component 51 can be a pulse power supply, or a pulse current generator, or other equipment or circuit that can generate pulse current, and can be specifically configured using techniques well known to those skilled in the art.

[0041] The second power supply component 52 can be an ordinary battery, or can be other circuits or devices that can generate detection current, and can be specifically configured using techniques well known to those skilled in the art.

[0042] The second power supply assembly 52 is electrically connected to the positive line 30 and the negative line 40, respectively, to output the detection current to the positive line 30 and the negative line 40. Then, when the positive line 30 and the negative line 40 are turned on, the detection current can flow. When the user holds the body 10, the positive line 30 and the negative line 40 can be touched at the same time, so that the user acts as a conductor for connecting the positive line 30 and the negative line 40, and then the detection current will flow through the user. In some embodiments, the detection current may be direct current. In some embodiments, the power of the second power supply assembly 52 in providing the detection current is less than the power of the pulse current provided by the first power supply assembly 51. In some embodiments, the detection current does not produce a tactile sensation to the user. In some embodiments, when the second power supply assembly 52 cooperates with the positive line 30 and the negative line 40, a diode or a suppression circuit can be set in the circuit formed by the second power supply assembly 52 and the positive line 30 and the negative line 40 to prevent the pulse current from flowing into the second power supply assembly 52 and causing damage to the second power supply assembly 52. Of course, when the first power supply component 51 cooperates with the positive line 30 and the negative line 40, a diode or a suppression circuit can also be set in the circuit formed by the first power supply component 51 and the positive line 30 and the negative line 40 to avoid the detection current flowing into the first power supply component 51 and causing damage to the first power supply component 51.

[0043] The current sensor 53 is electrically connected to the circuit loop formed by the second power supply assembly 52 and the positive line 30 and the negative line 40, and then detects the detection current in the circuit loop to determine whether the positive line 30 and the negative line 40 are conductive by the detection current. The current sensor 53 can generate a signal based on the detection current to the power controller 54.

[0044] The power controller 54 can be a single chip microcomputer, a processor, or other. The power controller 54 is used to control the first power supply component 51 to output a pulse current. In some embodiments, the power controller 54 is electrically connected to the current sensor 53 to receive a signal generated based on the detection current sent by the current sensor 53. The power controller 54 can control the first power supply component 51 to output a pulse current based on the signal. In some embodiments, the power controller 54 can determine whether the positive line 30 and the negative line 40 are conductive based on the signal, and can control the first power supply component 51 to output a pulse current when the positive line 30 and the negative line 40 are conductive, and can control the first power supply component 51 not to output a pulse current when the positive line 30 and the negative line 40 are not conductive.

[0045] Through the cooperation between the first power supply component 51, the second power supply component 52 and the power supply controller 54, efficient use of energy can be achieved.

[0046] See also Fig.11 , Fig.11 for Fig.10A schematic diagram of the structure of the positive line 30 and the negative line 40, and the power module 50 in other embodiments in the illustrated embodiment. The current sensor 53 can be replaced by a voltage sensor 55. The voltage sensor 55 can be electrically connected to the second power supply component 52 to detect the output voltage of the second power supply component 52. The second power supply component 52 is configured with additional resistance, inductance and / or capacitance, etc., so that the output voltage value measured by the voltage sensor 55 is different when the positive line 30 and the negative line 40 are conductive and non-conductive. Furthermore, the voltage sensor 55 detects the output voltage of the second power supply component 52 to determine whether the positive line 30 and the negative line 40 are conductive through the output voltage. The voltage sensor 55 can generate a signal based on the output voltage to the power controller 54.

[0047] The power controller 54 is electrically connected to the voltage sensor 55 to receive a signal generated based on the output voltage sent by the voltage sensor 55. The power controller 54 can control the first power component 51 to output a pulse current based on the signal. In some embodiments, the power controller 54 can determine whether the positive line 30 and the negative line 40 are conductive based on the signal, and can control the first power component 51 to output a pulse current when the positive line 30 and the negative line 40 are conductive, and can control the first power component 51 not to output a pulse current when the positive line 30 and the negative line 40 are not conductive.
