The power switch module 107 controls power switches of the entire device.

The key module 102 is electrically connected to the power switch module 107, the key module 102 includes a first key 1021 and a second key 1022, and the first key 1021 and the second key 1022 are respectively electrically connected to the power switch module 107. The first key 1021 and the second key 1022 form different key triggering states under different pressing conditions. When at least one of the first key 1021 and the second key 1022 is in a triggered state, the power switch module 107 is powered on. For example, when any 1 or 2 of the 2 keys are pressed, the power switch module is powered on, and the whole device is turned on. Alternatively, when any 1 or 2 of the 2 keys are pressed, the first key 1021 and the second key 1022 output different electrical signals.

Further, the first button 1021 and the second button 1022 are further connected to the control module 101, the button states of the first button 1021 and the second button 1022 can be detected by the control module 101, and the control module 101 can detect and record the button states, thereby outputting corresponding control instructions.

The motion sensing sensor 103 is electrically connected to the control module 101 to output an electrical signal to the control module 101. Alternatively, the motion sensor 103 may be an acceleration sensor, a 6-axis angular velocity sensor, or the like, and the motion sensor 103 converts the acceleration and angular velocity data of the entire device into numerical values, which are provided to the control module 101.

The storage module 104 is electrically connected to the control module 101 and is used for storing images to be displayed and sounds to be played.

The display control module 105 is electrically connected to the control module 101 and is used for controlling the color of the LEDs and the brightness of each LED through PWM, so as to form different light effects.

As shown in fig. 2, the LED strip 106 is electrically connected to the display control module 105, and the LED strip 106 includes a plurality of RGB LEDs, wherein the LED strip 106 is arranged in a straight line or along the shape of the device, so as to form different light source positions on the surface of the shape of the device.

The control module 101 reads the key states from the first key 1021 and the second key 1022 respectively to obtain the current control mode of the device, and then reads the current LED color or usage mode of the device controlled by the preset built-in program. The control module 101 reads the sensor value from the motion sensor 103 and detects whether the motion of the device conforms to a predetermined motion pattern.

Meanwhile, the control module 101 reads the image to be displayed and the sound to be played from the storage module 104, and the control module 101 changes the display of the LED strip through the display control module 105 and emits the sound through the sound emitting device 108.

The utility model identifies the action of the user through action induction, combines the action with the combination of the keys, corresponds to various acousto-optic effects and increases the use interest of the toy.

The acousto-optic toy with dynamic picture display effect of the embodiment is practically used and operated as follows:

in the initial state, the first button 1021 and the second button 1022 are both in the initial position, wherein the first button 1021 is a switch button to control the activation of the whole device. When the user presses the first button 1021, the power switch module 107 receives an input signal from the first button 1021, i.e., the battery is powered on to other parts of the whole device.

Optionally, the control module 101 uses an STM32F030 or other similarly functioning single chip microcomputer. When the control module 101 is powered on and started, it is read that the pressing state of the first key 1021 is "on" and the pressing state of the key 103 is "off". Optionally, table 1 discloses a comparison table of button states and LED display colors of an acousto-optic toy with a dynamic picture display effect according to the present invention, where each button combination corresponds to one color.

First key	Second push button	R	G	B
					Opening device	Closing device	255	80	0
Closing device	Opening device	80	255	0
					Opening device	Opening device	255	255	255

According to the table in table 1, the color to be displayed of the current LED is found to be RGB 255,80, 0. The control module 101 sends the color to be displayed to the display control module 105, with all LEDs in the off state.

The user presses the first button 1021, releases the second button 1022 and swipes the device quickly. The control module 101 reads the 3-axis acceleration at the current moment from the motion sensing sensor 103, and the control module 101 counts time and reads the motion frequency for a preset duration. Wherein, the control module 101 determines the waving action and the posture of the user according to the change of the acceleration value along with the time. For example, if the control module 101 recognizes that the change of the acceleration value with time is a curve that continuously changes in one direction, it determines that the current user motion is a one-way swing. Correspondingly, table 2 is a comparison table of the combination of the action + the key status of the acousto-optic toy with the dynamic picture display effect, the display image and the sound.

Movement of	Key combination	Image of a person	Sound equipment
				At rest	Arbitrary		1	Is free of
One-way waving	Arbitrary		2						2
				Move back and forth	1	3	3
Move back and forth	2	4	4
				Move back and forth	3	5	5

According to the table of table 2, in the case of the combination of the one-way waving action + any key, the image to be displayed is 2 and the sound is 2. When the control module 101 identifies that the change of the acceleration value along with the time is a curve changing back and forth in two directions, the current user motion is determined as the back and forth swing. Accordingly, according to the table look-up in table 2, in the case of the back-and-forth waving action + any key combination, the image to be displayed is 3 and the sound is 3.

After judging the waving action of the user, the control module 101 reads the corresponding pre-stored image from the storage module 104 and transmits the image to the display control module 105, so that the toy is controlled by the display control module 105 to display the corresponding image. For example, the control module 101 reads the image 2 from the storage module 104, and transmits the image data to the display control module 105. Further, the control module 101 may also read the sound 2 from the storage module 104 and send the sound data to the sound generating device 108 for playing.

The LED light strip 106 has a plurality of RGB LEDs, optionally S, where S is 10 ≦ 30. In the present embodiment, the number of LEDs is 10, 15, 20, 25, and 30, and the number of LEDs is denoted as N, where N is any natural number.

The LED strips 106 are distributed according to the device structure and shape to form unique patterns. For example, the LED strip 106 includes a plurality of LEDs linearly distributed along a first direction, and a plurality of LEDs linearly distributed along a second direction, wherein the first direction intersects the second direction, and the LEDs include at least one row in the second direction. The first direction and the second direction are two intersecting directions. For example, the first direction is a transverse direction, the second direction is a longitudinal direction, and the first direction and the second direction are perpendicular to each other, so that the LED strips 106 form an array distribution, and the LEDs are light sources distributed at the positions of the entire column of nodes. Of course, the first direction and the second direction may also be configured as a curve to form the light bars distributed at intervals.

For convenience, the LEDs distributed at the node positions are defined as pixels, where image data corresponding to the LED strip 106 is a grayscale image with a height of N pixels and a width of at least 1 pixel.

After receiving the image data, the display control module 105 reads the N pixels in the first column, and sets the gray value of the pixel to the brightness of the LEDs numbered from 1 to N one by one. After a certain time interval, the next column of image data is read, the brightness of each LED is set, and the procedure is repeated. When the device is in motion, the display effect of the brightness change of each LED on the LED strip 106 constitutes a dynamic picture in space due to the persistence of vision effect of human eyes.

In this embodiment, the method for setting the brightness and color of the LED is as follows: all the RGB LEDs in the LED strip 106 have their R electrodes to the first power connection point, G electrodes to the second power connection point, and B electrodes to the third power connection point, and the PWM is electrically connected to the first power connection point, the second power connection point, and the third power connection point respectively. Specifically, the R poles of all the LEDs are connected together, the G poles are connected together, and the B poles are connected together, and the display control module 105 controls the power on R, G, B poles of all the LEDs using PWM to control the overall color of the LEDs. Further, the display control module 105 controls the common anode or the common cathode of each LED using PWM to control the brightness of each LED individually. Alternatively, the display control module 105 may also use LEDs with serial data interfaces that can independently control color and brightness.

The toy is provided with a lamp strip with a plurality of light sources, and the brightness of each light source is finely controlled to change along with time, so that the moving light sources form a dynamic picture, and the acousto-optic display effect is rich. The toy identifies the action of the user through action induction, combines the action with the combination of the keys, corresponds to various acousto-optic effects, and increases use interest.
