Drawings 1 to 3 are drawings of the utility model.

This implementation provides a bluetooth sound of taking rhythm etc. please refer to 1 to 3, including casing 10, locate speaker 11, circuit board 12 and a plurality of LED lamp pearl 13 in casing 10. The housing 10 is a closed housing 10. The speaker 11 is disposed toward the inner wall of the casing 10, and a sound outlet 14 is disposed on the inner wall of the speaker 11 toward the casing 10. The position of the shell 10 close to the LED lamp bead 13 is transparent or semitransparent.

Wherein, speaker 11 locates the side of casing 10, and LED lamp pearl 13 locates the top of casing.

The bottom of the shell 10 is provided with a power supply cabin 15 for installing a battery and supplying power for the sound equipment. The power supply consists of a 5mm socket, a switch, an LM2596S voltage transformation module and a positive and negative electrode pin expansion plate and is used for providing electric energy for the sound box. The 6V direct current input from the outside is output to a positive and negative interface expansion socket with 6 jacks for supplying other parts after passing through a self-locking switch and an LM2596S voltage transformation module.

The housing 10 is provided with control buttons 16 to facilitate control of the audio.

The LED lamp beads 13 are fixed on the mounting plate 17. The mounting plate 17 is fixed inside the housing 10.

Preferably, a mounting post is provided in the housing 10 for fixing the mounting plate 17. The mounting plate 17 is fixed to the mounting post by screws.

For the LED lamp beads 13 to display more beautiful, the LED lamp beads 13 are annularly arranged on the mounting plate 17.

A fixing post 18 is provided inside the housing 10, and the speaker 11 is fixedly coupled to the fixing post 18. The fixing posts 18 protrude from the inner wall of the housing 10, so that a distance is set between the sound emitting surface of the speaker 11 and the inside of the housing 10.

Preferably, the distance between the sound emitting surface of the speaker 11 and the inside of the casing 10 is one fifth of the length of the inside of the casing 10, so that the sound generated by the speaker 11 can be reflected inside the casing 10, and the energy of the sound waves can be collected inside the casing 10, so that the sound emitted from the sound emitting hole 14 is more energized.

The circuit board 12 carries control circuitry. The control circuit comprises a Bluetooth module, a power amplification module and an ArduinoProMini module. The Bluetooth module is used for being connected with external electronic equipment (such as a mobile phone, a tablet and the like) in a matching mode and acquiring audio data. The power amplifying module is used for processing the audio data and sending the audio data to the loudspeaker 11. The Arduino ProMini module is used for collecting audio data of the audio output interface so as to control the brightness of the LED lamp beads 13. The control circuit is electrically connected with the loudspeaker 11, the LED lamp beads 13 and the control keys 16.

Preferably, the circuit board is further provided with an audio input interface 19 for accessing audio signals through a wire.

The control button 16 includes a capacitive touch switch and two mercury tilt switches. The Bluetooth module comprises a Bluetooth power amplifier chip (model: CSR8635), and the Bluetooth power amplifier chip is electrically connected with the capacitance touch switch and the mercury tilt switch. The capacitance touch switch and the mercury tilt switch are connected with the Bluetooth module and used for controlling functions of pause, next music playing and the like. The self-reset button has the working principle that when the button is pressed down, the circuit is conducted, the button automatically rebounds after the button is released, and the circuit is disconnected.

The bluetooth dashboard [ P/P ] keys are collectively called [ PLAY/PAUSE ] → [ PLAY/PAUSE ].

When the button is pressed once, the music is played, the music is paused when the button is pressed again, and the playing is continued … when the button is pressed again

The present application uses the TTP223 touch sensor module instead of the self-reset button. The TTP223 touch sensor module output defaults to a jog high level, a normal low level. That is, when we press the touch area, the sensor OUT terminal outputs a high level, and a weak current signal is generated. When the finger leaves, the sensor OUT end restores to output low level.

The OUT end of the triode is connected with the base electrode of the 9013NPN type triode, when the triode is connected into a circuit to form a loop, if the OUT outputs an electric signal, the electricity flows from a collector electrode to an emitter electrode after being amplified, and the circuit is conducted. When OUT outputs a low level, the current is turned off. Through the switching circuit, a touch switch can be used to replace the self-reset button.

The [ PREU/V- ] and [ NEXT/V + ] buttons are replaced by mercury switches. For the two keys, the short-time conduction is [ switch the previous one ] or [ switch the next one ], and the long-time conduction is [ reduce the volume ] or [ increase the volume ]. When the mercury switch is used for refitting the two key positions, the two mercury switches are required to be in an inverted state at ordinary times

The power amplification module comprises a micro power amplification chip (model: PAM 8403). The speaker 11 is electrically connected to the power amplification module. The sound signal is led out from the pin of the audio output port of the Bluetooth module and is connected to the R position and the T position of the right sound channel of the power amplification module. The power amplification module is directly powered by a 5V power supply when working. Finally, the electrical signal is amplified and then output from the right channel output end of the power amplification module to the loudspeaker 11. Because the Bluetooth sound is connected with only one loudspeaker 11, the problem of wiring of the positive pole and the negative pole of the loudspeaker is not considered.

The Arduino Pro Mini module collects signals from audio data output by an audio output port, programs are compiled, and WS2812 RGB LED lamp beads 13 are controlled to make different responses according to received different signal values. Generally, the brightness and color of the LED lamp beads 13 are controlled according to the tone rhythm of the audio.

The right channel electric signal output through the audio output port of the Bluetooth module is collected by the analog port 3 of the Arduino Pro Mini module after the interference signal is processed by a pull-down resistor. The program of the rduino Pro Mini module processes the collected signal values, and controls the LED lamp beads 13 to execute different demonstration effects according to different signal values, so that different gorgeous light effects can be played according to different music rhythms.

Compared with the prior art, the utility model discloses external electronic equipment is connected to bluetooth module, obtains audio signal back rethread speaker and plays, and the LED lamp pearl of setting on the casing can carry out control luminance or colour according to audio signal. The utility model has the advantages of simple structure, convenient processing, simple operation and strong interest.

The technical content of the present invention is further described by the embodiments only, so that the reader can understand it more easily, but the embodiments of the present invention are not limited thereto, and any technical extension or re-creation according to the present invention is protected by the present invention. The protection scope of the present invention is subject to the claims.
