Bluetooth speakers are the most widely used speakers these days. Their compact size with portability and long battery life have made them a centre of attraction. Well we hereby take Bluetooth speakers to the next level by integrating touchless operation.
The Bluetooth speaker allows user to change music by just swiping their hand over the Bluetooth speaker. Also the speaker allows user to adjust volume by just raising and lowering their hand over the speaker. The user can thus operate the complete speaker operation without even having to touch his/her phone or the speaker.

This Gesture Controlled Bluetooth Speaker provides the following advantages:

• Full Contactless Usage

• Hand Swipe for changing to next song

• Raising or lowering hand to adjust volume

• Swiping hand to turn On the speaker

• Automatic turn Off when not in use

• High Bass and efficient sound quality

• Over 8 hours of Battery Life

• Lightweight compact device for portability

The gesture based speaker takes Bluetooth speakers to the next level of modernization. The device makes use of 6 watt speaker with subwoofer along with arduino, battery charging board, Lidar sensor, audio amplifier IC, Bluetooth module and Battery Set. The system uses Bluetooth module to allow phones to connect to the speaker for audio input.

The speaker also allows for an AUX connection for audio input and a separate charging input connector for battery charging. The audio signal received is amplified by the amplifier IC for boost the signal without any data loss. This signal is now passed on to the speaker module to be converted to quality sound.

The Lidar sensor is mounted on top of the Bluetooth speaker. The input from sensor is processed by arduino and passed on to the controller to increase/reduce volume, switch song or turn on the speaker. This allows for a contactless speaker operation.

The battery pack is used to supply power to the entire device. The battery power and discharge is controlled by battery charger and protection circuitry. This circuitry also includes an inbuilt logic system to turn off the system automatically to save power when not in use for over 5 minutes.
