[0002] As electronic devices become increasingly versatile, more and more electronic devices are beginning to use styluses as access ports. For example, large-screen mobile phones, tablet computers and other electronic devices are equipped with styluses to improve the convenience of user input operations.

When the palm is close to the antenna, the frequency of the antenna's transmission and reception will shift, and the signal strength of the antenna's transmission and reception will also decrease, resulting in a decrease in the antenna's transmission efficiency, affecting the signal transmission performance of the stylus.

[0028] Combine the following Figure 1 - Figure 4 A stylus pen and an electronic device assembly according to an embodiment of the present application are described.

[0029] like Figure 1 to Figure 2 As shown, according to some embodiments of the present application, a stylus pen is provided, which is applied to an electronic device, including:

[0030] Pen housing 1, antenna 2, dielectric block 3 and button 4.

[0031] The pen housing 1 is provided with an opening 11, and the antenna 2 is attached to the inner wall of the pen housing 1. The antenna 2 can be wirelessly connected to the antenna of an external device, such as a wireless connection with the antenna inside a mobile phone, so as to achieve the purpose of signal transmission and mutual control between the stylus and the mobile phone; the dielectric block 3 is arranged in the pen housing 1 and opposite to the antenna 2, and the button 4 is connected to the dielectric block 3 and extends from the pen housing 1 through the opening 11.

[0032] When the button 4 is not pressed, the stylus pen can be in an idle state, the dielectric block 3 is opposite to the antenna 2, the dielectric block 3 and the antenna 2 have a first opposite area, and the antenna 2 transmits a signal of a first wavelength; when the button 4 is pressed, for example, the user needs to hold the stylus pen to transmit signals with the mobile phone, the user's hand will be close to the antenna 2, the frequency of the antenna 2 transmitting and receiving signals will become higher, that is, the wavelength of the signal will become shorter, affecting the signal transmission efficiency and transmission distance of the stylus pen. The user's holding of the stylus pen can achieve the pressing of the button 4, so that at least part of the dielectric block 3 is away from the antenna 2, the dielectric block 3 and the antenna 2 have a second opposite area, the second opposite area is smaller than the first opposite area, and the frequency of the antenna 2 transmitting and receiving signals will become lower, that is, the wavelength of the signal will become longer, offsetting the influence of holding the stylus pen on the antenna 2, and the antenna 2 can continue to transmit the signal of the first wavelength.

[0033] Specifically, when the button 4 is pressed, that is, the stylus pen is in a handheld state, the user's hand will be close to the antenna 2, and the frequency of the signal transmitted and received by the antenna 2 will become higher, that is, the wavelength of the signal will become shorter, and the intensity of the signal transmitted and received by the antenna 2 will also be partially absorbed, affecting the signal transmission efficiency and transmission distance of the stylus pen. When the button 4 is in a pressed state, the button 4 can drive at least part of the dielectric block 3 away from the antenna 2, and the frequency of the signal transmitted and received by the antenna 2 will become lower, that is, the wavelength of the signal will become longer, so that the interference of the dielectric block 3 on the transmission and reception of the antenna 2 is reduced, offsetting the impact of the handheld stylus pen on the antenna 2.

[0034] Specifically, the pen housing 1 may be a plastic housing, which reduces the weight of the stylus pen and improves the feel of the stylus pen. In addition, the pen housing 1 may be at least partially a metal housing, such as an aluminum housing or a steel housing, and the antenna 2 may also be replaced by a partial metal housing to achieve the transmission of the stylus pen signal.

[0035] When the button 4 of the stylus provided in the embodiment of the present application is in a pressed state, it can drive at least a portion of the dielectric block 3 away from the antenna 2, thereby offsetting the influence of the hand on the antenna 2 when holding the stylus, ensuring the signal transmission performance of the antenna 2, and realizing stable transmission of the stylus signal.

[0036] Optionally, the antenna 2 is a loop antenna, and the loop antenna is coaxially arranged with the pen housing 1 .

[0037] Specifically, when the antenna 2 is a loop antenna, the loop antenna can play a good signal transmission performance in the small-volume stylus due to its small size, high radiation intensity, and low impedance. Moreover, the loop antenna is coaxially arranged with the pen housing 1, so that the outer periphery of the loop antenna can be closely attached to the inner wall of the pen housing 1, which can ensure the connection strength between the antenna 2 and the pen housing 1 on the one hand, and increase the setting size of the antenna 2 on the other hand, thereby improving the signal transmission performance of the stylus.

[0038] Alternatively, see Figure 1 The pen housing 1 comprises a pen tip 12 and a pen tail 13, and the opening 11 is arranged at the pen tail 13;

[0039] When the button 4 is in a pressed state, that is, the button 4 can move along the axial direction of the pen housing 1 , and because the button 4 is connected to the dielectric block 3 , the button 4 can drive the dielectric block 3 to move in a direction away from the pen tail 13 .

[0040] Specifically, the wavelength λ of the signal transmitted by the antenna 2 conforms to the following formula:

[0041] λ=λ0 / ε 1 / 2

[0042] Among them, λ0 is the wavelength of the transmission signal in the vacuum medium, and ε is the effective dielectric constant of the transmission medium of the transmission signal.

[0043] According to the above formula, when a transmission medium such as an arm (with a dielectric constant greater than that of a vacuum) is close to the antenna 2, the wavelength of the signal transmitted by the antenna 2 will be shortened. The degree of wavelength shortening is inversely proportional to the 1 / 2 power of the effective dielectric constant of the transmission medium. The effective dielectric constant of the transmission medium is related to the distance between the transmission medium and the antenna 2 and the contact area.

[0044] See also Figure 1, the stylus is in a free state, for example, the stylus is placed on a table, at this time, the dielectric block 3 is arranged opposite to the antenna 2, and the resonant frequency of the antenna 2 just falls within the Bluetooth frequency band range that the stylus can effectively pair. When the stylus is in a hand-held state, the resonant frequency of the antenna 2 is higher due to the proximity of the hand, that is, the signal wavelength of the antenna 2 will become shorter. At this time, the user can manually press the button 4, and the button 4 will move along the axial direction of the stylus when it is pressed, thereby driving the dielectric block 3 to move along the axial direction of the stylus and away from the antenna 2. At this time, the dielectric block 3 and the antenna 2 are misaligned, that is, the overlapping area of ​​the dielectric block 3 and the antenna 2 becomes smaller, the resonant frequency of the antenna 2 will become lower, and the wavelength of the signal transmitted by the antenna 2 will become longer, offsetting the influence of the stylus on the antenna 2 when holding the stylus, thereby improving the signal transmission performance of the antenna 2.

[0045] Optionally, the opening 11 is arranged on the side wall of the pen housing 1 , the side of the dielectric block 3 close to the opening 11 is connected to the button 4 , and the side of the dielectric block 3 away from the opening 11 is connected to the side wall of the pen housing 1 through an elastic member 5 .

[0046] Specifically, the elastic member 5 can be a spring, elastic plastic or elastic rubber. When the button 4 is in a pressed state, the button 4 can drive the dielectric block 3 away from the opening 11. At this time, the elastic member 5 is compressed, so that the dielectric block 3 is away from the antenna 2, thereby reducing the interference of the dielectric block 3 on the transmission and reception signals of the antenna 2, and offsetting the impact of the stylus on the antenna 2 when holding the stylus.

[0047] Alternatively, see Figure 2 The opening 11 is arranged on the side wall of the pen housing 1, and the dielectric block 3 includes a first dielectric block 31 and a second dielectric block 32, the first dielectric block 31 is connected to the button 4, and the second dielectric block 32 is fixed in the pen housing 1 and connected to the first dielectric block 31 through an elastic member 5.

[0048] The wavelength λ of the signal transmitted by the antenna 2 also conforms to the following formula:

[0049] λ=λ0 / ε 1 / 2

[0050] Among them, λ0 is the wavelength of the transmission signal in the vacuum medium, and ε is the effective dielectric constant of the transmission medium of the transmission signal.

[0051] See also Figure 2, the stylus is in a free state, for example, the stylus is placed on a table. At this time, the first dielectric block 31 and the second dielectric block 32 are both arranged relative to the antenna 2, and the resonant frequency of the antenna 2 just falls within the Bluetooth frequency band range that the stylus can effectively pair. When the stylus is in a hand-held state, the resonant frequency of the antenna 2 is higher due to the proximity of the hand, that is, the signal wavelength of the antenna 2 will become shorter. At this time, the user can manually press the button 4, and the button 4 will move along the radial direction of the stylus when it is pressed, thereby driving the first dielectric block 31 to move along the radial direction of the stylus and away from the antenna 2. At this time, the elastic member 5 is compressed due to the support of the second dielectric block 32, the resonant frequency of the antenna 2 will become lower, and the wavelength of the signal transmitted by the antenna 2 will become longer, offsetting the influence of holding the stylus on the antenna 2, thereby improving the signal transmission performance of the antenna 2.

[0052] Optionally, the antenna 2 is a Bluetooth antenna, and the Bluetooth antenna cooperates with an antenna inside the electronic device.

[0053] Specifically, the stylus pen can input information into the electronic device through user operation, such as inputting text into the electronic device, so as to achieve simple interaction between the stylus pen and the electronic device. The Bluetooth antenna cooperates with the antenna inside the electronic device, and the antenna 2 can be wirelessly connected to the antenna inside the electronic device, such as the antenna inside the mobile phone, so as to achieve the purpose of signal transmission and mutual control between the stylus pen and the mobile phone, thereby improving the diversity and efficiency of the interaction between the stylus pen and the electronic device.

[0054] Optionally, the material of the dielectric block 3 can be mica, wood, plastic or rubber, etc., and the dielectric constant of the dielectric block 3 is in the range of 1-10C. 2 / (N·M 2 ).

[0055] Specifically, the control of the dielectric constant of the dielectric block 3 can, on the one hand, effectively offset the influence of the hand on the antenna 2 when holding the stylus pen, and on the other hand, ensure that the antenna 2 can effectively pass through the dielectric block 3. If the dielectric constant of the dielectric block 3 is too small, it cannot effectively offset the influence of the hand on the antenna 2 when holding the stylus pen; and if the dielectric constant of the dielectric block 3 is too large, the loss of the signal transmitted by the antenna 2 is large, reducing the transmission efficiency of the antenna 2.

[0056] Alternatively, see Figures 1 to 3 The stylus pen further includes an electronic control component 6 , which is disposed in the pen housing 1 and electrically connected to the antenna 2 .

[0057] Specifically, the electric control component 6 includes a circuit board 61 and a battery 62, and the battery 62 and the antenna 2 are both electrically connected to the circuit board 61. The battery 62 can provide power to the circuit board 61 and the antenna 2, and the circuit board 61 can control the frequency and strength of the signal transmitted by the antenna 2, thereby improving the controllability and flexibility of the signal transmission of the antenna 2.

[0058] An embodiment of the present application also provides an electronic device assembly, including an electronic device and the stylus pen.

[0059] Specifically, when the button 4 of the stylus provided in the embodiment of the present application is in a pressed state, it can drive at least a portion of the dielectric block 3 away from the antenna 2, thereby offsetting the influence of the hand on the antenna 2 when holding the stylus, ensuring the signal transmission performance of the antenna 2, and achieving stable signal transmission between the electronic device and the stylus.

[0060] Optionally, the electronic device includes but is not limited to one of a smart watch, a mobile phone, a tablet computer, an e-book reader, an MP3 player, an MP4 player, a computer, a set-top box, a smart TV and a wearable device.
