[0039] The following embodiments are further explanations and supplements to the present invention and do not constitute any limitation on the present invention.

[0040] like Figures 1 to 8 As shown, the main feature of this invention, an electronic watch that changes with the rhythm of sound, is that it is equipped with a colorful LED unit 30 and a microphone pickup unit 60. The display of the colorful LED unit 30, such as color and / or brightness, can change with the volume of the external sound, realizing the effect of the display changing with the sound. It is suitable for large-scale performances, company team building activities, nighttime outings and other scenarios, and has a wide range of application prospects.

[0041] The electronic watch with sound rhythm change comprises a main control unit 20, an LED display unit 10, a microphone pickup unit 60 and a colorful LED unit 30.

[0042] The LED display unit 10 is electrically connected with the main control unit 20, and is used for displaying the function contents of the electronic watch, such as the common function contents of date, time, week, alarm clock and the like.

[0043] The microphone pickup unit 60 is electrically connected with the main control unit 20, and is used for picking up the sound of the external environment.

[0044] The colorful LED unit 30 is electrically connected with the main control unit 20, and the display effect, such as color and / or brightness, can be changed with the size of the external volume under the control of the main control unit 20, so as to realize the effect that the color changes with the sound.

[0045] When the microphone pickup unit 60 picks up the environmental sound, the main control unit 20 can convert the analog signal of the sound into a digital signal, and then generate a corresponding PWM duty cycle signal to send to the colorful LED unit 30, so as to control the display effect of the colorful LED unit 30, and realize the effect that the color and / or brightness of the colorful LED unit 30 changes with the sound.

[0046] Further, the electronic watch comprises a watch dial and a watchband. The forms of the watch dial and the watchband can refer to the prior art. In the embodiment, the watch dial is provided with a light-transmitting shell and a circuit board arranged in the light-transmitting shell. The LED display unit 10, the microphone pickup unit 60, the colorful LED unit 30 and the main control unit 20 are arranged on the circuit board. In this way, the colorful light emitted by the colorful LED unit 30 can be displayed through the light-transmitting shell.

[0047] Further, in order to improve the display effect, the LED display unit 10 is located in the non-edge area of the watch dial. The colorful LED unit 30 is arranged around the periphery of the LED display unit 10. When the colorful LED unit 10 does not emit light, the main area of the watch dial normally displays the common function contents. When the colorful LED unit 10 emits light, it emits light around the LED display unit 10, which not only helps to clearly see the actual function contents of the LED display unit 10, but also increases the display effect, improves the functional interest and displays very cool and amazing.

[0048] Further, in the embodiment, the color-changing LED unit 30 includes 12 color LED modules which are evenly distributed along the circumference of the watch face. Further, the color LED modules are distributed in a manner consistent with the distribution of the indicators on the clock which are used to represent time, i.e., the positions of the color LED modules correspond one-to-one to the positions of the hours on the clock, so that when the color LED modules emit light, the visual effect is more cool and dazzling.

[0049] Of course, the number of color LED modules included in the color-changing LED unit 30 is not limited, and can be greater than 12 or less than 12. Preferably, the number of color LED modules is set to 12, corresponding to the positions of the hours on the clock.

[0050] Further, the color LED modules are cascaded, and the color-changing LED unit 30 includes a plurality of (preferably 12) color LED modules which are cascaded. The color LED modules can be RGB LED modules which are known in the art, and which have an internal control IC which can parse data and store subsequent receipt. The color LED modules are cascaded by internal shift registers and can change color and / or brightness under the PWM control signal sent by the master control unit 20.

[0051] Further, the color LED modules are respectively provided with VDD, DIN, DOUT, and GND pins.

[0052] The VDD pins of the color LED modules are respectively connected to the working voltage VCC. The working voltage VCC is obtained by voltage conversion circuitry inside the chip from the supply voltage VDD provided by a power source such as a battery.

[0053] The GND pins of the color LED modules are respectively grounded.

[0054] The DOUT pins of each color LED module are respectively connected to the DIN pins of the next color LED module to form a cascade, the DIN pin of the first color LED module is connected to the master control unit 20, specifically to the P00 / INTO pin of the master control unit 20 U2. The DOUT pin of the last color LED module is left unconnected.

[0055] The DIN pin of the color LED module is a serial data input interface, which is used to receive the digital signal of the master control unit 20, including the address, color (RGB value) and other control instructions of the target color LED module. Each color LED module receives data through the DIN pin, processes the information required by itself, and then transmits the remaining data to the DIN pin of the next color LED module through the DOUT pin, forming a chain control structure, so that cascading expansion can be realized. For example, when the master control unit 20 sends a signal containing data of 12 color LED modules (such as 24-bit RGB value + control bit), D1 processes the first data, D2 processes the second data, and so on.

[0056] The cascading structure of the color LED unit 30 can realize single-line control, and only one signal line (DIN) is needed to control an unlimited number of color LED modules, greatly simplifying the wiring. In addition, each color LED module has a fixed position in the data chain and can be individually set in color and / or brightness, making it easier to control dynamic lighting effects.

[0057] Further, the color LED unit 30 also includes a transistor Q1 for controlling the switching of the color LED unit 30.

[0058] The base of the transistor Q1 is connected to the control signal pin PW of the master control unit 20 through the resistor R6, for receiving the PWM control signal. The emitter of the transistor Q1 is connected to the positive of the power supply, i.e. the supply voltage VDD. The collector of the transistor Q1 is connected to the VDD pin of each color LED module.

[0059] The transistor Q1 is a switch of the color LED unit 30, which is used to control all color RGB modules to realize dimming and / or switching functions. When the transistor Q1 is off, it can cut off the power supply of all color LED modules, eliminating static power consumption. In addition, the transistor Q1 can control the on-off ratio through the PWM control signal sent by the master control unit 20, realizing the start-stop of the color LED module, so as to realize dimming.

[0060] In this embodiment, the transistor Q1 is a S8550 type PNP transistor, and in other embodiments, other types can also be selected as needed.

[0061] Further, the microphone pickup unit 60 includes a microphone MIC and an amplification circuit. The microphone MIC is electrically connected to the amplification circuit. The output end of the amplification circuit is electrically connected to the master control unit 20. The sound signal picked up by the microphone MIC is amplified by the amplification circuit and then transmitted to the master control unit 20 for processing.

[0062] Further, the amplification circuit comprises two-stage amplification transistors Q2 and Q3, and the microphone MIC cooperates with the two-stage transistor amplification.

[0063] The base of the transistor Q2 is connected to the positive pole of the microphone MIC through the capacitor C7, and the negative pole of the microphone MIC is grounded. The emitter of the transistor Q2 is grounded, and the collector is connected to the base of the transistor Q3. The emitter of the transistor Q3 is grounded, and the collector is electrically connected to the main control unit 20, specifically to the P01 / INT1 pin of the main control unit 20 U2.

[0064] Further, the positive pole of the microphone MIC is also connected to the working voltage VCC through the resistor R9 and the resistor R7; the base of the transistor Q2 is also connected to the working voltage VCC through the resistor R10 and the resistor R7; the collector of the transistor Q2 is also connected to the working voltage VCC through the resistor R11 and the resistor R7; and the collector of the transistor Q3 is also connected to the working voltage VCC through the resistor R8 and the resistor R7. Among them, the resistor R7 is used for current limiting protection of the transistors Q2 and Q3.

[0065] Further, the common connection end of the resistors R7, R9, R10, R11 and R8 is grounded through the capacitor C8, wherein the capacitor C8 is used for signal coupling.

[0066] In the embodiment, the pre-amplification stage Q2 adopts the R10 bias resistor, cooperates with the C7 high-frequency compensation capacitor, and realizes wide-band sound pickup. The second-stage amplification Q3 sets the working point through the resistors R11 and R9, and the capacitor C8 completes signal coupling. When the microphone MIC picks up sound signals, the capacitor C7 performs high-frequency filtering, then the transistor Q2 performs pre-amplification, the R10 / R9 divides voltage, the transistor Q3 performs current amplification, and then outputs to the P01 / INT1 pin of the main control unit 20 corresponding to the MIC signal.

[0067] The main control unit 20 is built-in with an ADC to convert the analog signal output by the microphone pickup unit 60 into a digital signal. The main control unit 20 can generate a corresponding PWM control signal for controlling the display effect of the colorful LED unit 30, so that the color LED modules of the colorful LED unit 30 realize the effect of changing with sound.

[0068] In the embodiment, the unit machine control unit is externally connected to the crystal oscillator Y2 and the load capacitors C2 and C3 through the P11 / XOUT pin and the P10 / XIN pin, for realizing precise time base, which can be used for PWM frequency reference and clock reference of the LED display unit 10. One end of each of the load capacitors C2 and C3 is grounded, and the other end is connected to the two ends of the crystal oscillator Y2.

[0069] Thus, the electronic watch with sound rhythm change is formed. In working, the microphone pickup unit 60 picks up the external sound, and the analog signal sound signal is transmitted to the main control unit 20 and is processed into a digital signal, under the control of the main control unit 20, the color LED module of the colorful LED unit 30 carries out corresponding light emission and generates the color changing effect with sound.

In the embodiment, the circuit structure of the display unit is shown in the figure, and the text part is not described in detail, which can display time, week, battery capacity and other information under the control of the main control unit 20.

[0071] Further, the electronic watch with sound rhythm of the application further includes a key unit 40, which is arranged on the circuit board and is electrically connected with the main control unit 20. The key unit 40 is used for function switching of the LED display unit 10. In some embodiments, it can also be used for start-stop control of the colorful LED unit 30.

[0072] The circuit structure of the key unit 40 can refer to the known technology, and in the embodiment, it includes the key MODE and SET, one end is grounded respectively, and one end is connected to the MODE signal pin PO4 / INT4 and SET signal pin PO3 / INT3 / SCK of the main control unit 20 U2 respectively.
