DIY Bluetooth Speaker Production and Assembly Electronic Welding Kit Teaching Practice DIY Electronic Kit Component

 

Description:

1. It can be controlled by remote control to realize the volume control of the switch

2. Full-range speaker with PU side, silver-black diaphragm 40 magnets 4 ohms 3W, high-cost performance, clear sound quality

3. Interface 3.7-5V DC power supply to automatically play music, stereo power amplifier, support Bluetooth, support power-off memory, U disk to play music

4. Acrylic shell is composed of 6 pieces of 3mm high transparency acrylic spliced together. Exquisite and beautiful, the brown protective film needs to be removed before splicing

5. Very suitable for welding connection and DIY production teaching and training

 

Parameter:

Channel output: 2 channels

Output power: 3w+3w

Power supply voltage: DC 4.2-5V, voltage 5V exceeding will damage the module

Rated current: 1.5A-2A

Wiring instructions: connect the white terminal to the speaker and the red terminal to the power supply

Bluetooth operation: Turn on the Bluetooth of the mobile phone, scan the device directly, and find "XC

046 Click to connect. After disconnecting Bluetooth, it will automatically switch to the USB flash drive.

 

Circuit function:

The red terminal of the Bluetooth module is a 5V power supply, the white terminal is for the left and right channels of the speaker, the red wire is positive +, and the black is negative -. With the sound of music or other sounds, the LED lights follow the rhythm of the sound (the speed of the sound flashes and moves. After the welding is successful, you can feel the beautiful melody combination of sound and light. Circuit principle: voice-activated LED melody The lamp circuit is composed of a power supply circuit, a microphone amplifier circuit, and an LED light indicator circuit. The power supply uses two batteries. The MIC converts the sound signal into an electrical signal, which is coupled to Q1 through C2 for amplification, and the amplified signal is sent to U1 and U1 pushes the LED to emit light, The louder the sound, the higher the brightness of the LED, the faster the water flow

 

Notice:

All parts need to be installed by yourself. The outer cover is transparent if the paper is torn off. The whole set of Bluetooth speaker kits is equipped with a USB power cord. The Bluetooth circuit boards are all welded. You only need to connect the wire and assemble the sound control board. The power supply can be powered by a mobile phone charger or a computer 5V. The sound quality is better when using a current of 2A.

Reminder: Please strictly follow the product instructions. Improper use and wiring will cause the amplifier to fail to work normally or damage the amplifier.
