How to make Bluetooth speakers speaker?
 Jun 24, 2021|View:553

When it comes to Bluetooth speakers speaker, there are hundreds of options and the price is different. However, when you can build a product that is not only integrated with your decoration, but also leaves a deep impression on your friends, why also buy it? Just a little imagination, almost anything can be turned into a Bluetooth speaker. lunch box? Is Ukiri broken? Jewelry boxes? Der web radio? An old Thangka truck? How about a table or a bookcase? Yes, these can be made into Bluetooth speakers. In addition to the position and method of fixed components, the steps to complete the project are as follows.

Step 1: assemble the Bluetooth speaker receiver

Step 2: Test the receiver to cut the two-segment pairing speakers cable. By heating with the soldering iron and applying a little solder, the two terminals on each excitation device are plated. Tin-plated lines and terminals make them easier to welded together and help build better electrical connections. Welded the two tin-plated ends of a speaker cable to the terminal of one of the incentives. Pay attention to the correct polarity. Repeat the use of another speaker cable and incentive. Positive and polarity will be marked with "+" or coloring with red dyes. Connect the other end of the two speaker cables to the terminals on the Bluetooth receiver, and pay attention to the polarity again. And test whether the Bluetooth speakers speaker are available.

Step 3: Find out the position of the storage incentive to open the receiver. Put the back glue side of a incentive (like, do not remove the back lin at this time) on the surface of the "speaker", and gently press it with a finger to fix it there. Slowly move the motives until you find a better place-this can be completed inside or outside the "speaker". Mark the point with a painter or beautiful paper tape. Do the same thing for another incentive.

Step 4: Install the receiver to find a suitable place to install the receiver. If you need to control the outer knob, the area needs to be thin enough so that the nut can be stuck on the axis of each control. Measure and mark the position of the three holes. Drill the cave, insert the shaft into the hole and tighten it with a nut. Install a knob on the shaft. By removing the stickiness, they are placed in the previously determined position and pressed hard to adhere them to install the excitation machine. Re-connect the speaker cable to the receiver, trim it to the appropriate length, peel off the end, and then install it in the speaker terminal to pay attention to the polarity. Use the electrical tape to fix the loose wire as needed.

Step 5: The mother-in-seat insertion of the AC to DC adapter finds the accurate position of the socket, and the holes of the appropriate size are drilled by it by heating and applying a little solder to place the end of the socket on the back of the socket. Take down the nut from the thread on the socket, press the socket into the hole, replace the nut and tighten. Find the power cord attached to the receiver-one end of it should have a public plug, and the other end is a naked and skinny tin-plated line. Cut a pair of red and black DC power cords, which is enough to connect the power cord on the receiver to the installed mother socket. Dip off both ends and platly tin on each end. Welded the positive and negative electrode (red and black) to the power line on the receiver. Welded the other end (positive and negative poles) to the correct terminal on the mother-in-law. Please note that the terminal of the intermediate needle is usually positive, but please check the electric source adapter, which will indicate whether the middle needle is the positive pole. Use electric tape wrap welding to prevent them from getting in and short circuit.

Step 6: Test the speaker to close the Bluetooth speakers speaker and insert the power adapter. Open the receiver. Turn to the phone, tablet or laptop settings, and then open Bluetooth. Go to your Bluetooth connection, find new devices, connect and start enjoying your music.


If you need to control the speaker design, buy a Bluetooth module and amplifier circuit board separately. When performing this operation, make sure that the two components need the same voltage, and you match it to the correct AC to the DC converter. If you are willing, you can also use traditional speakers. Make sure to match the design of the resistance (in Ohm) and power (in Watt) with the design purpose of the amplifier. You can also use charging lithium-ion batteries to power the Bluetooth speakers speaker, as long as it provides the correct voltage.
