Embodiment
Be described principle of the present utility model and feature below in conjunction with accompanying drawing, example, only for explaining the utility model, is not intended to limit scope of the present utility model.
As Fig. 1, a kind of industrial noise reduction bluetooth earphone, comprise a head rail 1, two cantilevers 2, left headset main body 3, right earphone main body 4, wherein two cantilever 2 one end connect respectively at head rail 1, the other end respectively with headset main body 3, 4 are connected, head rail comprises a wireless charging receiving terminal 5, described left headset main body 3, right earphone main body 4 comprises a loud speaker 17 respectively, described left headset main body 3 also comprises an active noise reducing device 6, blue-tooth device 7, Mike 8, contact button 9 and mains switch 20, described right earphone main body 4 also comprises an energy battery 10, described microphone 8 connects described loud speaker 17 through active noise reducing device 6, described contact button 9 connects active noise reducing device 6, described blue-tooth device 7 connects described loud speaker 17, and the alarm signal received from production equipment, the alarm signal received is play by loud speaker (17).
Active noise reducing device 6 is connected with contact button 9, and contact button 9 is for Temporarily Closed active noise reduction function.Finger dubs button, and switch disconnects, and decrease of noise functions is closed, finger release button, and switch connection, decrease of noise functions recovers.When the temporary close of active noise reduction function, microphone 8 pick up external sound and power amplifier to user.Be specially, when needs decrease of noise functions, unclamp contact button 9, microphone 8 picks up external sound, through wire by transmission of sound signals to filter circuit, filter circuit processes accepting voice signal, then by the transmission of sound signals after process to amplifying circuit, form the noise signal contrary with the noise signal that microphone 8 receives after amplifying circuit operation amplifier, two sound that now phase place is contrary neutralize mutually, noise disappears, and plays noise control function.When not needing noise control function, press contact button 9, microphone 8 picks up external sound, through wire, voice signal is directly passed to loud speaker 17, without active noise reduction circuit board 18, now, be busy with the workman worked in hand, external sound can be heard very clearly by loud speaker 17, need not earphone be taken off, more convenient.In addition, because contact button 9 is on the left of earphone, workman can press contact button 9 with left hand, does not affect the normal work of the right hand.
Blue-tooth device 7 can realize production equipment abnormality alarm prompting transfer function, and earphone blue-tooth device 7 can carry out pairing with production equipment and be connected, and when pairing successful connection, the abnormality alarm prompting sound that lathe sends is play by ear on-board speaker.In addition, earphone blue-tooth device is restricted to and can only carries out pairing with given production equipment and be connected, and can not carry out pairing with other equipment and be connected, as smart mobile phone, can prevent like this workman operationally between music appreciating, thus bring potential safety hazard.
