For example, a process, method, system, article, or apparatus that comprises a list of steps or elements is not limited to only those steps or elements listed, but may alternatively include other steps or elements not listed, or inherent to such process, method, article, or apparatus.

First, a structure and a device of a communication system to which the present application is applied will be described with reference to fig. 1 and 2.

Fig. 1 is a schematic diagram of a possible structure of a communication system according to an embodiment of the present application. The communication system 100 comprises a charging box 10, a TWS headset 20, the charging box 10 comprising a first optical transmitter 101, a first optical receiver 102, a first charging terminal 103, the TWS headset 20 comprising a second optical transmitter 201, a second optical receiver 202, a second charging terminal 203. The TWS headset includes a first headset and a second headset, in this embodiment, the first headset and the second headset have the same structure and function, and for convenience of description, the first headset and the second headset are not distinguished, and are both referred to as the TWS headset. It is to be understood that the number of earpieces in the TWS earpiece 20 is not limited, for example, the TWS earpiece 20 includes one earpiece; the configuration shown in fig. 1 does not constitute a limitation of the communication system in the present embodiment, and may include more or less components than those shown, or combine some components, or a different arrangement of components.

In general, a TWS headset is provided with an optical device, such as a proximity optical sensor, in which the light beam axis of a light emitting diode (or semiconductor laser tube) and the axis of a phototransistor are in a plane and form an included angle, and the two axes intersect at a point in front of the sensor. When the surface of the detected object is close to the intersection point, the reflected light signal of the light emitting diode is received by the phototriode to generate an electric signal. When the object is far away from the intersection point, the reflecting area is not in the visual angle of the phototriode, and the detection circuit does not output. May be used to detect whether the TWS headset is worn into the ear.

In the present embodiment, since the proximity light sensor has the complete transmitting portion and receiving portion, it is possible to take the transmitting portion of the proximity light sensor in the TWS headset 20 as the second light emitter 201, take the receiving portion of the proximity light sensor as the second light receiver 202, and arrange the devices that can be used in cooperation with the proximity light sensor in the TWS headset 20 as the first light emitter 101 and the first light receiver 102 in the charging box 10.

In the present embodiment, the charging box 10 and the TWS headset 20 perform transmission and reception of optical signals through their respective optical transmitters and optical receivers, and can operate while charging, achieve bidirectional communication, and avoid the use of additional metal terminals for communication.

It should be noted that the embodiment of the present application is not limited to the selection of the specific proximity light sensor type, and the above description is only for explanation.

Fig. 2 is a schematic diagram of a possible structure of a communication system according to another embodiment of the present application. Referring to fig. 2, including the charging box 10, the TWS headset 20, the charging box 10 includes: the first optical transmitter 101, the first optical receiver 102, and the first charging terminal 103, the TWS headset 20 includes: a second optical transmitter 201, a second optical receiver 202, and a second charging terminal 203. It is different from the communication system structure provided in fig. 1 in that separate optical device transmitting and receiving modules are provided as the second optical transmitter 201 and the second optical receiver 202 in the TWS headset 20, and the same separate optical device transmitting and receiving modules as those of the TWS headset 20 are arranged in the charging box 10. In addition, the two communication system structures can complete the same function, and the same beneficial effect is generated.

It should be noted that, the transmitting and receiving modules of the independent optical devices in the TWS headset 20 may specifically have various options, including but not limited to, for example, infrared emitting diodes, infrared receiving diodes, etc., which are not limited in this embodiment of the present application.

The communication method of the present application is described in detail below with reference to fig. 3 to 8.

Referring to fig. 3, fig. 3 is a schematic flowchart of a communication method for a charging box to send a communication signal to a TWS headset according to an embodiment of the present application, and the method is applied to a charging box (for example, 10 in the TWS headset communication system illustrated in fig. 1 and fig. 2) in a TWS headset communication system to implement that the charging box sends a communication signal to the TWS headset, and specifically includes the following steps:

s101, controlling a first light emitter of the charging box to emit a first detection light signal.

The first detection optical signal is mainly applied to TWS headset in-box detection. Specifically, for example, the first light emitter may start emitting the first detection light signal in response to an opening operation of the charging box.

S102, determining that the TWS earphone is in a box-in state and generating a first communication signal according to a first detection optical signal which is received by the first optical receiver of the charging box and reflected back from the TWS earphone.

In specific implementation, when the TWS headset is in the box-in state, the first charging end of the charging box is in contact with the second charging end of the TWS headset, the first detection optical signal is reflected by the TWS headset at a certain angle after entering the TWS headset, and the first optical receiver receives the first detection optical signal reflected by the TWS headset at a certain angle to confirm that the TWS headset is in the box-in state. In a specific implementation, the setting of the reflection angle is determined by a designer according to actual needs, and is not specifically limited in this embodiment.

Specifically, the box-in state refers to that the TWS headset is in a correct box-in position, the first charging end and the second charging end can be correctly contacted, and the first optical receiver in the charging box can receive the first detection optical signal after the incident TWS headset is reflected by the TWS headset at a certain angle.

After confirming that the TWS headset is in the docked state, the charging cradle may start communication and generate the first communication signal. In this embodiment, the first communication signal is typically a binary communication signal, and is composed of digital 1 and 0 codes, and different binary communication signals represent different communication contents. In specific implementation, designers can design communication signals corresponding to different communication contents according to different requirements. The different communication content may generally include, but is not limited to, switch box information, power information, or pairing information, etc.

In a specific implementation, the charging box may further generate a first communication signal according to the second communication optical signal received by the first photoreceptor.

S103, controlling the first optical transmitter to transmit a first communication optical signal to the TWS earphone in a pulse mode according to the first communication signal.

In this embodiment, the first communication signal is a binary signal, and the first light emitter may flash and emit a corresponding first communication light signal according to the binary signal after acquiring the first communication signal, for example, emit pulsed light at a high level and do not emit light at a low level. That is, the binary communication signal can control the first light emitter to emit the first communication light signal with the brightness variation.

For example, referring to fig. 4, if the first communication signal generated by the charging box is the first communication signal 410, the first optical transmitter transmits the first communication optical signal 420 to the TWS headset according to the first communication signal 410. The first communication signal 410 is a binary communication signal, for example, the first communication signal 410 is "1010101010", and the flash form of the corresponding first communication optical signal 420 is "on/off, on/off". The 1 is high level, the high level controls the first light emitter to be on, the 0 is low level, and the low level controls the first light emitter to be off. Fig. 4 is an exemplary diagram, and does not limit the present invention.

The pulse mode may also be a continuous pulse mode, as shown in fig. 5, the first communication signal 510 generated by the charging box exists in binary form of "0111101111", the first optical transmitter transmits the first communication optical signal 520 according to the first communication signal 510, and the first communication optical signal 520 flashes in form of "bright and bright" and "bright and bright" respectively. The first communication signal 510 exists at a continuous high level "1111" enabling control of the first optical transmitter in the form of a continuous pulse to generate a continuously bright first communication optical signal. That is, the first communication signal may be transmitted by the first optical transmitter in the form of a single pulse or a continuous pulse.

It should be understood that fig. 4 and fig. 5 are only used for describing and explaining the embodiment, and the present application is not limited thereto, and specific contents of the first communication signal and the first communication optical signal in the embodiment of the present application are set by a designer according to actual use requirements when implemented.

Optionally, according to the first communication signal in the binary form, the first optical transmitter may transmit the first communication optical signal that flickers in an on-off form, or may transmit the first communication optical signal that flickers in a strong-weak light form.

Specifically, in this step, the specific manner and the related emission setting of the first light emitter for emitting the communication light signal may be set by a designer according to a specific use scenario and a requirement, and only the method is described in this embodiment, which is not particularly limited.

Optionally, after the TWS headset is confirmed to be in the box-in state, the charging box charges the TWS headset, the charging process is implemented by cooperation of respective charging ends of the charging box and the TWS headset, and the charging end is a metal terminal.

Referring to fig. 6, fig. 6 is a flowchart illustrating a communication method for a TWS headset to receive a communication signal of a charging box according to another embodiment of the present application, which is applied to a TWS headset (for example, 20 in the TWS headset communication system illustrated in fig. 1 and fig. 2) in a TWS headset communication system to implement that the TWS headset receives the communication signal sent by the charging box, and specifically includes the following steps:

and S201, controlling a second optical receiver of the TWS earphone to receive a first communication optical signal under the condition that the second charging end of the TWS earphone is contacted with the first charging end of the charging box.

After the charging box transmits the first communication optical signal to the TWS headset, the TWS headset receives the first communication optical signal through the second optical receiver. Specifically, the second optical receiver may collect the optical signal according to the preset time interval H0 directly according to the change of the first communication optical signal emitted by the first optical transmitter, wherein H0 is set by a designer according to a specific use condition, and is not limited specifically herein. It will be appreciated that this process may be carried out with charging.

Specifically, in this step, the specific manner and the related receiving setting of the second optical receiver for receiving the first communication optical signal may be set by a designer according to a specific use scenario and a requirement, and only the method description is performed in this embodiment, which is not limited in this respect.

Further, after the first optical transmitter transmits the first communication optical signal, in the process that the second optical receiver receives the first communication optical signal, the first optical receiver may receive a reflected optical signal of the first communication optical signal, and the first optical transmitter and the first optical receiver may cooperate to realize a function of continuously performing earphone in-box detection in the communication process. Specifically, if the first optical receiver receives a first communication optical signal reflected from the TWS headset, it is determined that the TWS headset is still in the in-box state, the first optical transmitter may continue to transmit the first communication optical signal, and the charging box continues to communicate with the TWS headset; and if the first optical receiver does not receive the first communication optical signal reflected by the TWS earphone, the TWS earphone is determined not to be in the box-in state, the first optical transmitter stops transmitting the first communication optical signal, and the charging box ends the communication with the TWS earphone.

It should be explained that the function of continuously performing the earphone in-box detection may be set by a designer according to a specific use scenario and a requirement, which is not limited in this embodiment and does not affect an actual communication process.

S202, acquiring a first communication signal according to the first communication optical signal received by the second optical receiver of the TWS earphone.

After receiving the first communication optical signal transmitted by the first optical transmitter of the charging box, the second optical receiver may generate a corresponding electrical signal according to a change of the first communication optical signal, that is, directly convert the first communication optical signal into a high level and a low level. For example, as shown in fig. 4, the first communication optical signal transmitted by the first optical transmitter is assumed to be the first communication optical signal 420, the first communication optical signal received by the second optical receiver is assumed to be the first communication optical signal 430, and the first communication signal acquired by the TWS headset is assumed to be the first communication signal 440 according to the first communication optical signal 430 received by the second optical receiver. The first communication optical signal 430 is represented in the form of "on/off light on/off", and the converted first communication signal 440 is "1010101010". Since the first communication light signal received by the second optical receiver is generated by the first optical transmitter flashing in a varying pulsed manner directly from the first communication signal, the signal acquired by the TWS headset in binary code form is the same as the first communication signal in code form, and the first communication signal 410 generated by the charging box is the same in representation and content as the first communication signal 440 last acquired by the TWS headset. And finally, the TWS earphone processes the acquired signal to acquire the communication content represented by the first communication signal.

It should be understood that fig. 4 is only used for describing and explaining the embodiment, and the present application is not limited thereto, and the specific content of the first communication signal and the first communication optical signal in the embodiment of the present application is set by a designer according to the actual use requirement when implemented.

Compared with the prior art, the charging box sends the first communication signal to the TWS earphone to realize contactless communication, the use of the metal terminal is reduced, the situation that normal communication cannot be achieved due to the fact that the metal terminal is affected by the outside is avoided, the size of the communication device can be reduced through the use of the existing device, the cost is reduced, and the communication efficiency can be improved due to the fact that the communication device is simple and easy to achieve in the communication process.

Referring to fig. 7, fig. 7 is a flowchart illustrating another communication method provided by the embodiment of the present application, and is applied to a TWS headset (for example, 20 in the TWS headset communication system illustrated in fig. 1 and fig. 2) in a TWS headset communication system, so as to implement that the TWS headset sends a communication signal to a charging box, where the method specifically includes the following steps:

and S301, generating a second communication signal according to the first detection optical signal received by the second optical receiver of the TWS headset.

And after receiving the first detection optical signal transmitted by the first optical transmitter, the second optical receiver confirms that the TWS earphone is in the box-in state. After confirming the entry, the TWS headset generates a second communication signal to begin communicating with the charging box.

The second communication signal is a binary communication signal and is composed of digital 1 and 0 codes, and different binary communication signals represent different communication contents. In specific implementation, designers can design communication signals corresponding to different communication contents according to different communication scene requirements. The different communication content may generally include, but is not limited to, switch box information, power information, or pairing information, etc.

In a specific implementation, the TWS headset may further generate a second communication signal according to the first communication optical signal received by the second photoreceptor.

S302, controlling the second optical transmitter to transmit a second communication optical signal in a pulse mode according to the second communication signal.

In this embodiment, the second communication light signal may be generated by flashing a light in a varying pulse manner directly according to the second communication signal, wherein the second communication signal is a binary signal, and the second light emitter may emit the second communication light signal with a variation in intensity according to the second communication signal existing in the binary signal. Optionally, the pulse mode may be a single pulse or a continuous pulse, and the specific explanation of the different pulse modes has been described above, and is not described in detail here to avoid repetition.

Optionally, according to the second communication signal in the binary form, the second optical transmitter transmits the second communication optical signal that may blink in the on-off form, or may blink in the strong light form or the weak light form.

Specifically, in this step, the specific manner and the related emission setting of the first optical transmitter for emitting the first communication optical signal may be set by a designer according to a specific use scenario and a requirement, and only the method is described in this embodiment, which is not limited specifically.

It should be noted that, after the second optical transmitter transmits the second communication optical signal to the charging box, the second communication optical signal may generate a reflection at a corresponding angle and then be received by the second optical receiver, and the second optical receiver determines whether to receive a reflected optical signal of the second communication optical signal transmitted to the charging box by the second optical transmitter in the communication process, which is not limited to this, and is set by the operator, and the setting of the reflected optical signal may be implemented by setting related software so as not to receive the reflected optical signal, or may not be performed. The reflected light signal is received without affecting the communication process and without producing a correlation effect.

Referring to fig. 8, fig. 8 is a flowchart illustrating a method for a charging box to receive a TWS headset communication signal according to another embodiment of the present application, which is applied to a charging box (for example, 10 in the TWS headset communication system illustrated in fig. 1 and fig. 2) in a TWS headset communication system to implement that the charging box receives a communication signal sent by a TWS headset, and specifically includes the following steps:

s401, controlling the first optical receiver of the charging box to receive a second communication optical signal.

After the TWS headset sends the second communication optical signal to the charging box, the charging box receives the second communication optical signal through the first optical receiver. Specifically, the first optical receiver may collect the optical signal at a certain time interval H0 directly according to the change of the second communication optical signal emitted by the second optical emitter, wherein H0 is set by a designer according to a specific use condition, and is not limited herein.

Specifically, in this step, the specific manner and the related receiving setting of the first optical receiver for receiving the second communication optical signal may be set by a designer according to a specific use scenario and a requirement, and only the method description is performed in this embodiment, which is not limited in this respect.

S402, acquiring a second communication signal according to the second communication optical signal received by the first optical receiver of the charging box.

After receiving the second communication optical signal transmitted by the second optical transmitter of the TWS headset, the first optical receiver may generate a corresponding electrical signal according to a change of the second communication optical signal, that is, directly convert the second communication optical signal into a high level and a low level. For example, as shown in fig. 4, the second communication optical signal transmitted by the second optical transmitter is set as a second communication optical signal 420, the second communication optical signal received by the first optical receiver is set as a second communication optical signal 430, and the second communication signal acquired by the charging box is set as a second communication signal 440 according to the second communication optical signal 430 received by the first optical receiver. The second communication optical signal 430 is represented in the form of "on/off", and the converted second communication signal 440 is "1010101010". Since the second communication light signal received by the first optical receiver is generated by the second optical transmitter flashing in a varying pulsed manner directly from the second communication signal, the signal acquired by the charging box in binary coded form is the same as the second communication signal coded form, and the second communication signal 410 generated by the TWS headset is the same in representation and content as the first communication signal 440 last acquired by the charging box. And finally, the charging box processes the acquired signal to acquire the communication content represented by the second communication signal.
