To alert the user. At the same time, the right earphone 12 itself will sound an alarm.
In the wearing process, if the user oneself takes the earplug 2 of right earphone 12 with the hand, then can appear NFC chip 3 and can't respond to each other, but the human body can be sensed to the proximity sensor 4 homoenergetic of left and right ear, and at this moment, think that the user oneself has taken right earphone 12, then can not send the chimes of doom.
After the design, the risk of loss in the wearing process of the wireless earphone is greatly reduced.
As shown in fig. 1 and fig. 2, in the embodiment, the short-range wireless communication unit includes an NFC chip 3, and a short-range wireless communication distance of the NFC chip 3 is not greater than 20 cm. A Near Field Communication (NFC) function is integrated in the NFC chip 3, and the NFC chip 3 can preferentially use a PN544 chip; wherein, the English of NFC is Near Field Communication, the Chinese means Near Field Communication technology, the NFC chip 3 has the function of mutual Communication and has the computing capability.
in this embodiment, the proximity sensor 4 is a laser type proximity sensor, and a PA22409001 sensor may be preferably used, and the human body sensing distance of the proximity sensor 4 is greater than 20 cm.
In this embodiment, the earplugs 2 are respectively arranged on the left earphone 10 and the right earphone 12, and the laser type proximity sensor is arranged in the earplugs 2; thus, the earplug 2 is inserted into the ear when worn, ensuring that the proximity sensor 4 can sense the human body.
in addition, the wireless earphone of the invention can be provided with a proximity sensor 4 in the left earphone 10 or the right earphone 12, or can be provided with the proximity sensor 4 in both the left earphone 10 and the right earphone 12, or can be not provided with the proximity sensor 4; thus, once the distance between the left earphone 10 and the right earphone 12 is greater than 20cm, an alarm can be given, which prevents loss even if the left earphone 10 or the right earphone 12 is in the hand.

when step S18 is included, step S20 is performed in the manner of:
If not, the alarm unit is controlled to alarm according to the alarm signal.
If not, the dropped earphone is not in the hand, for example, when the dropped earphone falls on the ground and cannot sense a human body, the main control unit controls the alarm unit to alarm according to the alarm signal.
As shown in fig. 1 to 5, if no in step S15, the step of generating the alarm signal includes:
Generating a local alarm signal, wherein the local alarm signal is used for controlling an alarm unit arranged on the same side of a short-distance wireless communication unit which does not realize short-distance wireless communication to alarm; and/or
Generating a wireless alarm signal, wherein the wireless alarm signal is used for controlling an alarm unit arranged on the opposite side of the proximity sensor 4 which does not sense the human body to alarm;
The wireless alarm signal is transmitted by wireless communication between the main control unit in the left earphone 10 and the main control unit in the right earphone 12.
For the sake of clearer description, the following are illustrated:
in the wearing process, if the right earphone 12 accidentally falls off and the left earphone 10 does not fall off, the alarm method comprises the following steps:
the master control units in the left earphone 10 and the right earphone 12 both judge that the NFC chips 3 in the left earphone and the right earphone do not realize the short-distance wireless communication;
If the judgment result is no, the main control unit in the left earphone 10 generates an alarm signal, and the main control unit in the right earphone 12 also generates an alarm signal;
Then, the master control units in the right earphone 12 and the left earphone 10 judge whether the proximity sensor 4 in each sense the human body;
If the judgment result is 'no', the main control unit in the right earphone 12 generates a wireless alarm signal, and the wireless alarm signal is wirelessly transmitted to the main control unit in the left earphone 10 through the Bluetooth function by the main control unit in the right earphone 12; meanwhile, the main control unit in the right earphone 12 generates a local alarm signal; if the judgment result is 'yes', the main control unit does not execute the alarm signal to control the alarm unit to alarm even if the main control unit acquires the alarm signal, and the situation of false alarm is avoided.
finally, the main control unit in the left earphone 10 controls the alarm unit in the left earphone 10 to alarm according to the received wireless alarm signal so as to remind the user; meanwhile, the main control unit in the right earphone 12 controls the alarm unit in the right earphone 12 to alarm according to the local alarm signal.
by the aid of the alarm method, the risk of loss of the wireless earphone in the wearing process is greatly reduced.
The above-described preferred embodiments of the present invention are not intended to limit the present invention, and any modifications, equivalent modifications, etc. made within the spirit and principle of the present invention should be included in the scope of the present invention.
