Abstract
The invention discloses a portable back-hanging type Bluetooth earphone for brain wave signals, which comprises an earphone body. The earphone body comprises a brain wave sensor, a filtering and amplifying unit, an analog-to-digital converter and a brain wave acquiring and processing chip. The brain wave sensor, the filtering and amplifying unit, the analog-to-digital converter and the brain wave acquiring and processing chip are sequentially connected and are distributed in cerebral occipital regions. The filtering and amplifying unit comprises a first amplifier, a wave trap, a low-pass filter, a band-pass filter and a second amplifier. The first amplifier, the wave trap, the low-pass filter, the band-pass filter and the second amplifier are high in input differential impedance and are sequentially connected. The earphone body is in the form of a Bluetooth earphone. The brain wave acquiring and processing chip is matched and connected with a target terminal through the Bluetooth means, so that the brain wave acquiring and processing chip and the target terminal are in communication with each other. According to the technical scheme of the invention, brain wave signals are detected by the Bluetooth earphone, and then the interactive communication between the Bluetooth earphone and the target terminal is realized. The brain wave signals are filtered and amplified by the filtering and amplifying unit, so that the brain wave signals can be acquired and processed more accurately.
