Description

Technical Field

[0001] This application relates to the technical field of mouse control circuits, and in particular to a touch mouse control circuit with vibration feedback function. Background Technology

[0002] With the continuous development of computer interaction technology, human-computer interaction devices such as mice, keyboards, and touchscreens are constantly being optimized in terms of functionality and user experience. Traditional mice provide clear tactile feedback through physical buttons and scroll wheels, allowing users to intuitively perceive the operation status, such as clicking and scrolling. However, touch mice, which have emerged in recent years, use touch surfaces to replace traditional mechanical buttons. While this improves the flexibility and versatility of operation, it also brings the problem of a lack of tactile feedback.

[0003] In traditional mice, mechanical buttons and scroll wheels provide users with clear click feedback and haptic feedback through physical displacement and micro-switch activation, thereby enhancing the certainty and precision of operations. Touch mice, on the other hand, rely on capacitive or pressure-sensitive touch technology. When a user's finger slides or lightly touches the smooth touch surface, there is a lack of physical feedback, which can easily lead to misoperations or uncertainty. For example, users cannot confirm whether a command was successfully triggered through touch when clicking, or they have difficulty perceiving the boundaries and response status of gestures.

[0033] This application discloses a touch mouse control circuit with vibration feedback function.

The power supply module 2, motor drive module 5, touch sensor, and lighting module 6 are all controlled and connected to the controller 1. The output terminal of the power supply module 2 is electrically connected to the power supply terminal of the controller 1 through the first boost module 3, and the output terminal of the power supply module 2 is electrically connected to the power supply terminal of the vibration feedback motor drive module 5 through the second boost module 4. The motor drive module 5 is used to control the rotation of the vibration feedback motor to achieve the vibration feedback function.

[0035] In this embodiment, controller 1 is configured as a microcontroller with touch detection capabilities, enabling it to effectively recognize input signals from touch sensors. Upon receiving an input signal, controller 1 can control the motor drive module 5 and the lighting module 6 according to pre-embedded instructions. The microcontroller also has a reserved I2C interface, allowing for the establishment of a communication port via a Bluetooth motherboard.

[0036] refer to Figure 2 The first boost module 3 includes a boost chip U1. Pin 3 of the boost chip U1 is grounded, and the output terminal POWER of the power module 2 is electrically connected to pins 1 and 6 of the boost chip U1.

Pin 4 of the boost chip U1 is set as the output terminal of the first boost module 3, and in this embodiment, the output voltage of the first boost module 3 is 5V. By adjusting the resistance values ​​of resistors R1 and R2, the first boost module 3 can output different voltage values. Preferably, the first boost module 3 also includes a capacitor C1. One end of the capacitor C1 is electrically connected to pin 4 of the boost chip, and the other end of the capacitor C1 is grounded. By setting the capacitor C1, it can play a role in filtering and stabilizing the voltage.

[0037] refer to Figure 2 and Figure 3 The structure of the second boost module 4 is the same as that of the first boost module 3, including a boost chip U2, a capacitor C2, a resistor R3, a resistor R4, and an inductor L2. In this embodiment, the output voltage of the boost chip U2 is 5V.

[0038] refer to Figure 4 The motor drive module 5 includes a drive chip U3. Pin 2 of the drive chip U3 is electrically connected to the voltage output terminal POWER of the power supply module 2, and pins 5 and 8 of the drive chip U3 are grounded. Pins 6 and 7 of the drive chip U3 are electrically connected to the two signal output terminals of the controller 1, and pins 1 and 4 of the drive chip U3 are electrically connected to the positive input terminal and the negative input terminal of the vibration feedback motor, respectively.

[0039] When controller 1 receives the output signal from the touch sensor, it can start the vibration feedback motor through the control chip U3, enhancing the mouse's interactive experience. Furthermore, the driver chip U3 can adjust the speed of the vibration feedback motor via the PWM signal output from controller 1, achieving dynamic adjustment of vibration intensity and frequency, thus providing vibration feedback for different operations, such as weak vibration for a light touch, strong vibration for a hard press, and continuous vibration for scrolling.

[0040] Furthermore, the motor drive module 5 also includes capacitors C3 and C4. One end of each capacitor is electrically connected to the voltage output terminal POWER, and the other end is grounded. By using capacitors C3 and C4, the power supply voltage of the motor drive module 5 can be effectively filtered and stabilized, reducing the impact of voltage fluctuations on the operation of the vibration feedback motor, thereby improving the stability and reliability of the vibration feedback. Preferably, the vibration feedback motor is a flat motor with a smaller overall size, thus enabling it to be placed in a smaller space.

[0041] refer to Figure 5 The lighting module 6 includes an RGB light group, transistors Q1, Q2, and Q3, and a power supply VDD. In this embodiment, the output voltage of the power supply VDD is 5V. The RGB light group includes LED1, LED2, and LED3, where LED1 emits green light, LED2 emits red light, and LED3 emits blue light.

The output terminal LED_G of controller 1 is grounded through resistors R12 and R13 in sequence. The connection point between resistors R12 and R13 is electrically connected to the base of transistor Q3, and the emitter of transistor Q3 is grounded.

[0042] The output terminals LED_B, LED_R, and LED_G of controller 1 are used to output PWM signals. When output terminal LED_B outputs a high level, transistor Q1 is turned on, and LED3 in the RGB light group illuminates; when output terminal LED_B outputs a low level, transistor Q1 is turned off, and LED3 in the RGB light group does not illuminate. Similarly, transistors Q2 and Q3 operate on the same principle, thus enabling the control of the illumination states of LED1, LED2, and LED3 to achieve different display effects as needed.

[0043] The implementation principle of a touch mouse control circuit with vibration feedback function in this application embodiment is as follows: the power module 2 provides the basic voltage for the system, and provides a stable operating voltage for the controller 1 through the first boost module 3 to ensure the reliability of signal processing. At the same time, the second boost module 4 provides the driving voltage for the motor drive module 5. The touch sensor detects the user's touch operation in real time and transmits the signal to the controller 1. After receiving the output signal, the controller 1 controls the motor drive module 5. The motor drive module 5 precisely adjusts the start, stop, frequency and intensity of the vibration feedback motor according to the instructions of the controller 1 to achieve differentiated tactile feedback effects.
