LP581620 4P 680mAh Lithium Polymer Battery used for Smart Strap
The operation mode of the Smart Strap equip with the LP581620 4P 680mAh Lithium Polymer Battery,
The Smart Strap receives voice signals from your mobile phone via Bluetooth. After receiving the voice signal, it will generate vibration through its body conduction unit, which will transmit to your fingertips through your hand. Since the transmission is carried out by vibration, it will not cause harm to the human body. When you place your fingertips on your ears, the vibrations will echo to produce amplified sounds in the enclosed space of the ears.
Smart Strap sound quality test with LP581620 4P 680mAh Lithium Polymer Battery, the blue image represents the original sound signal input, and the magenta image represents the sound signal when received through the fingertips. In voice transmission, the voice frequency range is about 2000 Hz. The sound signal passing through the fingertip changes little from the original input sound signal within this range.
