Insider Tip

Use your PC or mobile device settings to minimize audio delay in a multi-room wireless speaker system.

How to Build Bluetooth Speakers

If you want to know how to make speakers Bluetooth, you’ll need a wireless speaker conversion kit or audio signal transmitter. Luckily, adapting wired speakers is much easier than building them from scratch.

Research some of your favorite models and take note of the stylish designs and features you might want for your DIY wireless speakers. For example, you can learn how to make Bluetooth speakers & computer speakers play simultaneously for multi-room audio.

STEP 1 Pick Your Speakers

The type of speakers you choose will heavily affect your audio quality. For example, you want the best-made large Bluetooth speakers for bass-heavy music or multi-room audio. In contrast, micro speakers are ideal for outdoor adventures or medium-sized rooms.

STEP 2 Make the Speaker Enclosure

Some users choose wood or 3D-printed stylish designs, but you can make the speaker enclosure out of anything you like, including recycled materials. You want a box-type shape, and you should cut out holes for speakers and analog audio inputs.

Ensure the enclosure is big enough to fit the speaker, internal components, and batteries. Additionally, you should make a spot for the battery power cable so you can easily charge the speaker.


Do not crowd your wireless or wired speakers because clutter can muffle your sound, diminishing the audio quality.

STEP 3 Install the Speakers

Use the hot glue gun around the edge of the speakers and press them onto the speaker holes.

STEP 4 Connect the Amplifier Module to the Bluetooth transmitter

Unless your speakers have a built-in amplifier, your speakers need an external amplifier. Wire your speakers to the amplifier, and then connect the wireless receiver and transmitter audio cables. If you want to make the speakers accessible to a non-Bluetooth device, consider adding an Aux cable to it like the one you can find in our Oontz Angle 3 review.

You can then use the hot glue gun to attach these boards to the inside wall of the speaker enclosure.

STEP 5 Prep Your Batteries

Wire your batteries and install a battery charge protection module to prevent overcharging or electrical hazards. Attach the battery component to the amplifier module.

STEP 6 Wire the Power Button, Volume Control, and Pairing Button

Connect your power cables, and volume controls to the battery unit. Place these units into the enclosure, and secure them in place with hot glue or with screws.

STEP 7 Test Your Speaker

Charge the batteries or attach the power cable, and ensure your DIY speakers work. Test the Bluetooth connection and sound quality.

STEP 8 Finalize the Enclosure

Once you’ve tested the speakers, you can assemble the rest of the enclosure.

How to Make Bluetooth Speakers at Home FAQs

How do I maximize my speaker’s rechargeable battery?

You can ensure hours of battery life by not overcharging your speakers. Once the battery indicator shows a full charge, disconnect the speakers from the power cable.

Do smart speakers listen to you?

Smart home devices like Google Home and the Amazon Echo are always listening, but they are not recording. For example, your Google Nest listens for wakeup terms that indicate a search or command.

Are Wi-Fi speakers better than Bluetooth?

Wi-Fi speakers offer excellent audio and a robust wireless signal thanks to the increased bandwidth over Bluetooth models. That said, Bluetooth 4.0 devices are usually cheaper and more portable.
