The acrylic shell is made of 6 pieces of 3mm high-transparency acrylic spliced together. Exquisite and beautiful, you need to tear off the brown protective film before splicing \u003cbr\u003e5. Very suitable for welding contact and DIY production teaching training \u003cbr\u003e\u003cbr\u003eParameter: \u003cbr\u003eChannel output: 2 channels \u003cbr\u003eOutput power: 3w+3w \u003cbr\u003ePower supply voltage: DC 4.2-5V, if the voltage exceeds 5V, the module will be damaged \u003cbr\u003eRated current: 1.5A-2A \u003cbr\u003e\u003cbr\u003eWiring instructions: the white terminal is connected to the speaker and the red terminal is connected to the power supply \u003cbr\u003e\u003cbr\u003eBluetooth operation: Turn on the Bluetooth of the mobile phone, you can scan the device directly, find the \"XC \u003cbr\u003e046 Click to connect. After disconnecting the bluetooth, it will automatically switch to the USB flash drive. \u003cbr\u003e\u003cbr\u003eCircuit function: \u003cbr\u003eThe red terminal of the bluetooth module is 5V power supply, the white terminal is 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 will move with the rhythm of the sound (the speed of the sound and the size of the sound. After the welding is successful, you can feel the wonderful 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-emitting indicator circuit. The power supply adopts 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 drives the LED to emit light. , the louder the sound, the higher the LED brightness, the faster the water flow. \u003cbr\u003e\u003cbr\u003eNotice: \u003cbr\u003eAll the parts need to be installed by yourself. The casing paper is torn off and it is transparent. The whole set of bluetooth speaker kit has been equipped with uSB power cord, and the bluetooth circuit board is all welded, just need to connect the cable and assemble the sound control board to use, the power supply can be powered by a mobile phone charger or a computer 5V, and a power supply with a current of 2A has better sound quality . \u003cbr\u003e\u003cbr\u003eReminder: Please strictly follow the product instructions. Improper use and wiring will cause the amplifier to fail to work normally or damage the amplifier. \u003cbr\u003e\u003cbr\u003ePackage List: \u003cbr\u003eDIY parts*1 \u003cbr\u003e\u003cimg class=\"wscnph\" src=\"https:\/\/ae01.alicdn.com\/kf\/S8cc7933604774d9da2c20bf7d92bd09eA.jpg\" slate-data-type=\"image\"\u003e\u003cimg src=\"https:\/\/ae01.alicdn.com\/kf\/Sb7bfed6fe7c94376bab9ebc6fed4f706d.jpg\" slate-data-type=\"image\"\u003e\u003cimg class=\"wscnph\" src=\"https:\/\/ae01.alicdn.com\/kf\/S5cb6eec7590b4f998920719bac3a5aa4H.jpg\" slate-data-type=\"image\"\u003e\u003cimg class=\"wscnph\" src=\"https:\/\/ae01.alicdn.com\/kf\/S5a49246d88a748378a7de980d81b7bceT.jpg\" slate-data-type=\"image\"\u003e\u003cimg class=\"wscnph\" src=\"https:\/\/ae01.alicdn.com\/kf\/S3df26311a1a44dd3aaa976a3b76797faU.jpg\" slate-data-type=\"image\"\u003e\u003cimg class=\"wscnph\" src=\"https:\/\/ae01.alicdn.com\/kf\/Sceb5b5f3e8c54ce8aeb9d8e2b8d60a1dD.jpg\" slate-data-type=\"image\"\u003e\u003cimg class=\"wscnph\" src=\"https:\/\/ae01.alicdn.com\/kf\/S632c3282d56a40ebb78f0253865170a6f.jpg\" slate-data-type=\"image\"\u003e\u003cimg class=\"wscnph\" src=\"https:\/\/ae01.alicdn.com\/kf\/S6869b069e1384f8481bf3ef192292e3a8.jpg\" slate-data-type=\"image\"\u003e\u003cimg class=\"wscnph\" src=\"https:\/\/ae01.alicdn.com\/kf\/S2905f988b6ec4009aa7f6941ea18f1924.jpg\" slate-data-type=\"image\"\u003e\u003cimg class=\"wscnph\" src=\"https:\/\/ae01.alicdn.com\/kf\/S9a49728de3e7459786862d8c469d5281h.jpg\" slate-data-type=\"image\"\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003c\/div\u003e\u003c\/div\u003e\u003cbr\u003e","brand":"Tech Gadget Hub","offers":[{"title":"Default-Default","offer_id":48901703762162,"sku":"182303430;20260323;17742902360PeCA","price":25.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0819\/5008\/1266\/files\/Sb7bfed6fe7c94376bab9ebc6fed4f706d.webp?v=1774290242","url":"https:\/\/techgadgethq.com\/products\/diy-bluetooth-speaker-production-assembly-electronic-welding-kit-teaching-practice-diy-electronic-kit-component-90759168242-iizyy","provider":"Tech Gadget Hub","version":"1.0","type":"link"}
