Detailed ways

In order to achieve the above-mentioned purpose and structure, the technical means adopted by the utility model and its effects, the drawing is hereby illustrated in detail with respect to the preferred embodiment of the utility model and its steps and functions are as follows, in order to fully understand. the

Please refer to Fig. 1, Fig. 2, and Fig. 3, which are respectively the three-dimensional appearance diagram, structural diagram and hardware block diagram of a preferred embodiment of the present utility model. It can be clearly seen from the figure that the utility model touch-type wireless mouse 1 is a control module 12 that includes a housing 11 and can be accommodated in the housing 11, wherein:

The casing 11 is composed of a base 111 and an upper cover 112, and an accommodating space 10 for accommodating the control module 12 is formed between the base 111 and the upper cover 112, and a pad 113 is combined under the base 111; An activation area 110 is defined on the surface of the body 11 . the

The control module 12 is provided with a circuit board 120 with multiple electronic components and circuit layout (not shown in the figure), and the multiple electronic components on the circuit board 120 include a microprocessor 121, a touch panel 122, a sound wave The sensing element 123 and the power supply module 124 are connected to the touch panel 122, the acoustic wave sensing element 123, and the power supply module 124 respectively with the microprocessor 121, and the acoustic wave sensing element 123 can be a piezoelectric microphone, a moving coil In addition, the power supply module 124 can be a rechargeable battery, a dry battery, etc., to supply the required power when the control module 12 is in the operating mode or standby mode, and can ensure that the acoustic wave sensing element 123 is continuously sensed and normal. In addition, the microprocessor 121 is connected with a switching unit 125, and the switching unit 125 can be a key switch, a touch switch, a piezoelectric switch, a capacitive switch or a mechanical switch, and the switching unit 125 can be set on The interior of the casing 11 or the upper cover 112 activates the area 110 , and forms an abutting contact or an electrical connection state with the activation area 110 . the

And when the utility model touch wireless mouse 1 performs the touch function, its standby mode wake-up process steps (as shown in Figure 4) include:

Step 101: The human body touches or knocks on the surface of the housing 11 of the touch wireless mouse 1 . the

Step 102: The acoustic wave sensing element 123 transmits a start-up power signal to the power supply module 124 for power supply. the

Step 103: The microprocessor 121 judges whether the switching unit 125 is on, if not, repeat step 101; if yes, go to step 104. the

Step 104 : the touch panel 122 triggers to generate an electrostatic signal, and transmits it to the microprocessor 121 , and at the same time, the acoustic wave sensing element 123 transmits the sensed resonance acoustic wave change to the microprocessor 121 . the

Step 105: The microprocessor 121 samples the resonant sound wave frequency, and judges whether it matches the built-in resonant sound wave frequency sampling value, if not, repeat step 101; if yes, go to step 106. the

Step 106: The microprocessor 121 transmits the displacement signal to the external electronic device 2 through the transmitting module 128 . the

From the above steps, it can be known that the control module 12 of the touch wireless mouse 1 forms an induction loop inside the casing 11, and a small amount of resonance can be formed when the user's finger touches or taps on the casing 11 Sound waves, and the sensed resonance sound wave changes are converted into voltage changes through the sound wave sensing element 123, and then the power supply signal is transmitted to the power supply module 124 for power supply, which can wake up the touch wireless mouse 1 in the standby mode; In other words, if the human body does not touch the housing 11 of the wireless touch mouse 1, the sound wave sensing element 123 will not generate a corresponding start-up power signal output; then the microprocessor 121 can judge the switch Whether the unit 125 is in the open state, at this time, if the user also places the hand on the range of the activation area 110 on the housing 11 (such as the position that the thumb, ring finger, little finger or palm can touch, etc.), switch the unit 125 is turned on immediately, and the microprocessor 121 can receive the switch signal after judging; The electrostatic signal can form a capacitive charging effect by touching the touch panel 122 with a finger, even if the electrode on the touch panel 122 forms a capacitive coupling with the finger and produces a capacitance change, thereby detecting the magnitude of the electrostatic signal current to calculate the contact position, To realize the touch function, and the touch technology can be surface capacitive (Surface Capacitive) touch technology or projected (Projected Capacitive) touch technology, but this part is about detecting and distinguishing multi-touch behaviors (such as Scaling, dragging, rotation, etc.) are not the focus of the present utility model, so only a brief description is made in this specification for understanding; moreover, the above-mentioned switching signal and static signal are transmitted to the microprocessor 121 respectively, When the microprocessor 121 receives the switching signal and the electrostatic signal, the microprocessor 121 will further sample the frequency of the resonant sound wave, and judge whether it conforms to the preset value of the built-in or external memory unit (not shown in the figure) of the microprocessor 121. Resonant sound wave frequency sampling value, the best embodiment of the resonant sound wave frequency sampling value range is between 20Hz ~ 20kHz, but in practical application, it is not limited by this, the resonant sound wave frequency sampling value range can be adapted to The different designs are subject to change, and the range of the preferred resonant sound wave frequency sampling value is only set to the general resonant sound wave frequency range that may be produced by the human body touching the surface of the touch wireless mouse 1, so as to eliminate The resonant sound wave frequency generated when pets, sundries on the desk or other objects accidentally touch the touch wireless mouse 1 is enough to prevent accidental touches from happening. the

Therefore, if the preset resonant sound wave frequency sampling value range is between 20Hz-20kHz, the microprocessor 121 judges that the received resonant sound wave frequency conforms to the resonant sound wave frequency sampling value range between 20Hz-20kHz, and its microprocessor 121 will Generate a corresponding trigger signal output, which means that after the microprocessor 121 receives the switching signal and the static signal, and judges that the resonant sound wave frequency is in line with the preset resonant sound wave frequency sampling value range, the touch mechanism becomes effective and becomes an effective key value. The processor 121 will receive the displacement signal transmitted by the displacement detection module 126; The unit 125 and the touch panel 122 generate corresponding switching signals and electrostatic signals, and if the microprocessor 121 judges that the resonant sound wave frequency does not meet its built-in preset resonant sound wave frequency sampling value range, the microprocessor 121 will not It will receive the displacement signal transmitted by the displacement detection module 126, and keep the touch wireless mouse 1 in standby mode. the

Furthermore, the above-mentioned control module 12 is connected with a displacement detection module 126 by a microprocessor 121, and the displacement detection module 126 can be an infrared sensor, a complementary metal oxide semiconductor (CMOS) image sensor or a charge-coupled device (CCD) ) image sensor, and can cooperate with the light emitting diode 127 or laser diode to reflect light to the light sensor to generate different pulse waves to calculate the displacement distance of the touch wireless mouse 1. However, how the displacement detection module 126 generates projected light and refraction imaging And X-axis, Y-axis moving distance and track calculation etc. belong to the category of the prior art, and the detailed composition is not the key point of the creation of this case, so without affecting the protection scope of the utility model, it will not be repeated here; therefore, the microprocessing The device 121 confirms that the touch mechanism is effective and becomes an effective key value, and the displacement signal of the touch wireless mouse 1 can be transmitted to the corresponding receiving module 21 of the external electronic device 2 (such as a computer, a notebook computer, etc.) through the transmitting module 128 and the transmission module 128 can also be a wireless transmission interface such as Bluetooth communication protocol (Bluetooth), radio frequency technology (RF), etc., for the touch wireless mouse 1 to perform related pointer operations and program execution on the electronic device 2 and other functions. the

In addition, the above description is only a preferred embodiment of the present utility model, which cannot limit the patent scope of the present utility model. When the touch wireless mouse 1 of the present utility model performs the touch function, its standby mode wakes up the process steps ( As shown in Figure 5) can also include:

Step 201: The human body touches or knocks on the surface of the casing 11 of the touch wireless mouse 1 . the

Step 202: The acoustic wave sensing element 123 transmits a start-up power signal to the power supply module 124 for power supply. the

Step 203 : the touch panel 122 triggers to generate an electrostatic signal and transmits it to the microprocessor 121 , and at the same time, the acoustic wave sensing element 123 transmits the sensed resonance acoustic wave change to the microprocessor 121 . the

Step 204: The microprocessor 121 judges whether the switching unit 125 is on, if not, repeat step 201; if yes, go to step 205. the

Step 205: The microprocessor 121 samples the resonant sound wave frequency and judges whether it matches the built-in resonant sound wave frequency sampling value. If not, repeat step 201; if yes, go to step 206. the

Step 206: The microprocessor 121 transmits the displacement signal to the external electronic device 2 through the transmitting module 128 . the

From the above steps, it can be known that when the user's finger touches or knocks on the surface of the housing 11, the acoustic wave sensing element 123 can convert the sensed change of the resonant sound wave of the housing 11 into a voltage change, and then transmit the starting power signal To the power supply module 124 for power supply, and when the human body touches the surface of the touch wireless mouse 1 to perform the touch function, the touch panel 122 can be triggered to generate an electrostatic signal and transmit it to the microprocessor 121, and the sound wave sensing element 123 The sensed change in the resonance sound wave is transmitted to the microprocessor 121, and then the microprocessor 121 can judge whether the switching unit 125 is in the open state. If the user places his hand on the activation area 110 on the housing 11, the switching unit 125 is turned on immediately, and the resonant sound wave frequency is further sampled by the microprocessor 121. If it is judged to meet the preset resonant sound wave frequency sampling value range of the memory unit, the touch mechanism becomes effective and becomes an effective key value, and the microprocessor 121 will Receive the displacement signal transmitted by the displacement detection module 126, and then transmit it to the external electronic device 2 through the transmitting module 128, so that the touch wireless mouse 1 is currently in the operation mode for use; in other words, if the user does not use it , only need to leave the hand from the activation area 110 on the housing 11, the switching unit 125 will be closed immediately, so that the touch wireless mouse 1 can also place the hand on the touch wireless mouse when the user does not move the cursor You can also place your fingers or the whole hand on the touch-sensitive wireless mouse 1 without lifting the fingers (such as the index finger and middle finger that the human body touches on the touch panel 122 for index operation). Or it is necessary to leave the whole hand completely away from the surface of the housing 11, so that the design of the switching unit 125 can form a multi-touch verification mechanism, thereby effectively improving the accuracy of the overall touch and ensuring better stability, as well as ease of use. Convenience, and can avoid improper wake-up of the touch wireless mouse 1, prevent accidental touches (such as pets at home, debris on the desktop or other objects touching the touch wireless mouse 1 caused by improper wake-up), and other Abnormal use behaviors (such as wrong command operation, input or program execution, etc.), can further improve the overall use function and effect, and make the product more competitive.

Therefore, the main feature of the present utility model is that the housing 11 of the touch wireless mouse 1 accommodates the control module 12, and the microprocessor 121 of the control module 12 is connected with the touch panel 122 and the acoustic wave sensing element 123 respectively. It is connected with the power supply module 124. When the human body touches the surface of the touch wireless mouse 1 to perform the touch function, the acoustic wave sensing element 123 can convert the change of the sensed resonance sound wave of the casing 11 into a voltage change, and then transmit and start The power supply signal is sent to the power supply module 124 for power supply. At the same time, the user places his hand on the activation area 110 on the casing 11, so that the switching unit 125 connected to the microprocessor 121 is turned on immediately, and when the microprocessor 121 After receiving the switching signal and the electrostatic signal triggered by the touch panel 122, and further sampling the resonant sound wave frequency to judge that it meets the preset resonant sound wave frequency sampling value, the touch mechanism becomes effective, and the microprocessor 121 will receive the displacement detection signal. The displacement signal transmitted by the measuring module 126, and then the displacement signal is transmitted to the receiving module 21 of the external electronic device 2 through the transmitting module 128 for pointer operation, thereby effectively improving the accuracy of the overall touch control and ensuring better stability. , and the convenience of use, while improving the problems of false touches and high input error rates caused by poor touch accuracy. The patent scope of the utility model, therefore, the simple modifications and equivalent structural changes made by using the description and drawings of the utility model should still be included in the patent scope covered by the utility model. the
