Description

Technical Field

[0001] This utility model relates to the field of electronic product technology, specifically to a three-in-one drive circuit for sound, light, and vibration. Background Technology

[0002] Micromotors, short for "miniature electric motors," refer to motors with a diameter less than 160mm or a rated power less than 750mW. Currently, micromotors are commonly used in control systems or transmission mechanical loads to perform functions such as detection, analysis, amplification, execution, or conversion of electromechanical signals or energy. Many existing micro or small products require the operation of micromotors to drive an eccentric wheel, causing the entire micro or small product to vibrate at high frequencies. Due to the needs of different application scenarios, it is often necessary to combine the vibration of these micro or small products with corresponding sound and light functions. Therefore, drive circuits integrating sound, light, and vibration functions are essential for these products. However, the current control circuits integrating sound, light, and vibration are relatively complex in structure and have a high failure rate, hindering widespread promotion and application. Utility Model Content

[0003] The purpose of this invention is to overcome the above problems and provide a dual micro motor control system that is simple in structure, has a low failure rate, and is easy to control.

[0007] The motor drive circuit consists of a transistor Q4, a resistor R4, and a mechanical switch SW1. The base of the transistor Q4 is connected to the control chip U5 via an external circuit. One end of the resistor R4 is connected to the base of the transistor Q4, and the other end is grounded. One end of the mechanical switch SW1 is connected to both the base of the transistor Q4 and the control chip U5, and the other end is grounded.

[0008] The auxiliary control circuit is a voice control chip U1, whose input pin is connected to the control chip U5 via resistor R26.

One end of the speaker LS is connected to the voice control chip U1, and the other end is connected to the headphone jack J. One end of the resistor R4 is connected to the voice control chip U1, and the other end is connected to the headphone jack J.

LED1 and resistor R5 are connected in series, and then the whole circuit is connected in parallel with resistor R7. The input terminal of the parallel circuit is connected to the voice control chip U1, and the output terminal is connected to the control chip U5. One end of capacitor C1 is connected to the input terminal of the parallel circuit, and the other end is grounded.

[0012] As a preferred embodiment, the charging circuit is composed of an XC4054 chip, an LY4054 chip, a TP4054 chip, or an ME4054 chip and its peripheral circuitry.

[0013] To ensure that the micro motor M is not damaged by reverse power supply, a diode D6 is connected in series between the positive and negative terminals of the power supply of the micro motor M. The N terminal of the diode D6 is connected to the positive terminal of the power supply of the micro motor M, and its P terminal is connected to the negative terminal of the power supply of the micro motor M.

[0020] Example

[0021] like Figure 1As shown, the system consists of a main control circuit, an auxiliary control circuit and a motor drive circuit connected to the main control circuit, a sound drive circuit and a light drive circuit connected to the auxiliary control circuit, a micro motor M connected to the motor drive circuit, and a power supply circuit connected to the main control circuit and the micro motor M.

[0022] The power supply circuit provides operating voltage and current to the main control circuit, auxiliary control circuit, motor drive circuit, sound drive circuit, light drive circuit, and micro motor M. The auxiliary control circuit, under the control of the main control circuit, drives the sound drive circuit and the light drive circuit. The motor drive circuit, under the control of the main control circuit, drives the micro motor M.

[0023] The specific circuit structure of this utility model is as follows: Figure 2 As shown, the main control circuit consists of a control chip U5 and its peripheral circuitry. The control chip U5 is preferably implemented using an MCU (Microcontroller Unit), which can be of any model, as long as it can perform the corresponding control functions. Similarly, the control chip U5 can be replaced by other similar chips or electronic components. It should be noted that because different models or package types of MCUs will have different pin counts and corresponding pin functions, during connection, it is only necessary to connect external electronic components to the corresponding functional pins; this will not affect the operation and control of the entire product.

[0024] For ease of understanding and explanation, this embodiment uses an 8-pin MCU as a specific example of the control chip U5.

[0025] like Figure 2 As shown, the peripheral circuit of the main control circuit is a filter circuit, namely a first-stage RC filter circuit composed of resistor R6 and capacitor C3, and a second-stage RC filter circuit composed of resistor R3 and capacitor C2. During connection, one end of resistor R6 is connected to pin 7 of control chip U5, and the other end is connected to pin 3 of main control chip U5 via resistor R3. One end of capacitor C3 is connected to the junction of resistors R6 and R3, and the other end is grounded; one end of capacitor C2 is connected to pin 3 of control chip U5, and the other end is grounded.

[0026] The motor drive circuit consists of transistor Q4, resistor R4, and mechanical switch SW1. The base of transistor Q4 is connected to control chip U5 via external circuitry, specifically to the junction of resistor R3 and capacitor C2, ensuring that pins 7 and 3 of control chip U5 can provide base control current to the base of transistor Q4. The emitter of transistor Q4 is grounded, and its collector is connected to the negative power supply terminal of the micro motor M.

[0027] One end of resistor R4 is connected to the base of transistor Q4, and the other end is grounded. One end of the mechanical switch SW1 is connected to both the base of transistor Q4 and pin 3 of control chip U5, and the other end is grounded. To ensure that the positive and negative terminals of the power supply to the micro motor M are not damaged by reverse current, a diode D6 is connected in series between the positive and negative terminals of the power supply to the micro motor M. When connected, the N-terminus of diode D6 is connected to the positive terminal of the power supply to the micro motor M, and its P-terminus is connected to the negative terminal of the power supply to the micro motor M.

[0028] The auxiliary control circuit is a voice control chip U1, whose input pin 8 is connected to pin 4 of the control chip U5 via resistor R26 to ensure that the control chip U5 can provide operating current and voltage to the voice control chip U1.

[0029] The sound driving circuit consists of a speaker LS, a headphone jack J, and a resistor R4. One end of the speaker LS is connected to pin 3 of the voice control chip U1, and the other end is connected to the headphone jack J. One end of the resistor R4 is connected to pin 4 of the voice control chip U1, and the other end is connected to the headphone jack J.

[0030] The lighting driving circuit consists of a light-emitting diode (LED1), resistors R7 and R5, and a capacitor C1. In the connection, LED1 and resistor R5 are connected in series, and then the entire circuit forms a parallel circuit with resistor R7. The input of this parallel circuit is connected to the voice control chip U1, and its output is connected to the control chip U5. Specifically, the N-terminal of LED1 is connected to pin 2 of the control chip U5 via resistor R5, and its P-terminal is connected to pin 5 of the voice control chip U1. One end of resistor R7 is connected to the P-terminal of LED1, and the other end is also connected to pin 2 of the control chip U5. Capacitor C1 is a surface-mount capacitor; one end is connected to the P-terminal of LED1, and the other end is grounded.

[0031] The power supply circuit consists of a rechargeable battery BT and a charging circuit, which is composed of an XC4054 chip, LY4054 chip, TP4054 chip, or ME4054 chip and its peripheral circuitry. Figure 2 As shown, the control chip U3 of this charging circuit has V in and V out Port, its V out The port is connected to the rechargeable battery BT, and its V in The port connects to the USB interface. Since the charging circuit is a very mature technology, it will not be described in detail in this embodiment.

[0032] As described above, this utility model can be well realized.
