Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, fig. 1 is a flowchart of a communication method according to an embodiment of the present invention. The method is applied to the wireless headset and can comprise the following steps:
step 101: and receiving a first laser signal sent by the charging box.
The wireless earphone can receive a first laser signal sent by the charging box by using a laser receiving module arranged on the wireless earphone; as shown in fig. 2, a laser receiving module including a receiving antenna, a photoelectric conversion device, and a demodulator may be disposed in the wireless headset, and in this step, the wireless headset may receive the first laser signal by using the receiving antenna in the laser receiving module. Correspondingly, a laser emission module corresponding to the wireless earphone can be arranged in the charging box to send a first laser signal.
Specifically, the specific structure and type of the laser receiving module used by the wireless headset to receive the first laser signal sent by the charging box in this step may be set by a designer according to a practical scene and a user requirement, and as long as the wireless headset receives the first laser signal sent by the charging box by using the laser receiving module, this embodiment is not limited thereto.
It can be understood that the first laser signal in this step may be a laser signal received by the wireless headset, such as a signal corresponding to a laser beam received by a receiving antenna in a laser receiving module in the wireless headset in fig. 2. Because the wireless laser communication between box and the wireless earphone charges, need to guarantee that the laser receiver can receive the laser signal that the laser generator sent, can carry out wireless laser communication with the box that charges in order to guarantee wireless earphone in the box that charges, when wireless earphone is in the box that charges promptly, the laser receiving module among the wireless earphone can receive the first laser signal that the laser emission module that this wireless earphone corresponds sent in the box that charges. That is to say, the setting position of the laser receiving module used by the wireless headset to receive the first laser signal sent by the charging box in this step may be after the wireless headset is placed in the charging box, for example, when the charging contact of the wireless headset is connected to the charging electric shock of the charging box, the position of the laser receiving module in the wireless headset corresponds to the position of the laser sending module corresponding to the wireless headset in the charging box, so as to ensure that the laser receiving module in the wireless headset after the wireless headset is placed in the charging box can receive the first laser signal sent by the laser sending module corresponding to the wireless headset in the charging box.
Specifically, the specific manner in which the wireless headset receives the first laser signal sent by the charging box in this step may be set by a designer, for example, in fig. 2, the laser receiving module in the wireless headset may be provided with a multilayer filter, so that the first laser signal received by the receiving antenna may be filtered out of stray light by the multilayer filter, and then enter the photoelectric conversion device for photoelectric conversion.
Correspondingly, the step of judging whether the wireless earphone is connected with the charging contact of the charging box or not by the wireless earphone can be further included before the step, so as to determine whether the first laser signal sent by the charging box can be accurately received or not. As shown in fig. 2, if the wireless headset is connected to the charging contact of the charging box, the processor (bluetooth platform) in the wireless headset may control the power supply and the charging management device to supply power to the laser receiving module, so as to perform this step by using the laser receiving module to receive the first laser signal sent by the charging box; if the wireless earphone is not connected with the charging contact of the charging box, whether the first laser signal sent by the charging box can be received or not can not be determined, the processor in the wireless earphone can control the power supply and the charging management equipment to not supply power to the laser receiving module, namely, the laser receiving module is not used for receiving the first laser signal, and the interference of other laser signals and the electric quantity loss of the wireless earphone are avoided.
Step 102: acquiring a first electric signal according to a preset carrier parameter in the first laser signal; the change rule of the first electric signal corresponds to the change rule of the preset carrier parameter of the first laser signal.
It can be understood that, in this step, the wireless headset may utilize the laser receiving module set by itself to convert the first laser signal into the first electrical signal that can be received and processed by the processor of the wireless headset according to the content of the preset carrier parameter in the first laser signal. In this step, the content of the first electrical signal may correspond to the content of the preset carrier parameter in the first laser signal, that is, the content of the first communication data sent by the charging box to the wireless headset in this embodiment may be carried in the content of the preset carrier parameter of the first laser signal.
Correspondingly, the specific parameter type of the preset carrier parameter is not limited in this embodiment, for example, the preset carrier parameter may be amplitude, that is, the variation rule of the first electrical signal corresponds to the variation rule of the amplitude of the first laser signal; the preset carrier parameter may also be other carrier parameters such as frequency, as long as the wireless headset can obtain the first electrical signal according to the preset carrier parameter in the first laser signal, which is not limited in this embodiment.
Specifically, for the wireless headset in this step, the specific manner of obtaining the first electrical signal by using the laser receiving module according to the preset carrier parameter in the first laser signal may be set by a designer, as shown in fig. 2, the wireless headset may first perform photoelectric conversion on the first laser signal by using a photoelectric conversion device in the laser receiving module to obtain a modulated electrical signal (e.g., a modulated pulse signal), and then demodulate the modulated electrical signal by using a demodulator to obtain the first electrical signal.
It should be noted that, the purpose of this step may be to convert the first laser signal into a corresponding first electrical signal by a laser receiving module in the wireless headset, so that a processor, such as a single chip microcomputer, in the wireless headset may obtain corresponding first communication data according to the received first electrical signal. Specifically, for the specific corresponding relationship between the variation rule of the preset carrier parameter of the first laser signal and the variation rule of the first electrical signal in this step, that is, the specific corresponding relationship between the content of the preset carrier parameter of the first laser signal and the content of the first electrical signal in this step, the specific corresponding relationship can be set by a designer according to a use scene and a user requirement, if the preset carrier parameter is amplitude and the first communication data is composed of digital signals of binary 0 and 1, the first electrical signal can be obtained according to the value of the amplitude of the first laser signal by setting the first amplitude range corresponding to the digital signal 0 and the second amplitude range corresponding to the digital signal 1 in this step, that is, when M is the value of the amplitude of the first laser signalH-thRepresenting the minimum amplitude value, M, of the digital signal 1L-thRepresenting the maximum amplitude value (M) of the digital signal 0H-th>ML-th) While passing the amplitude of the first laser signal and ML-thAnd MH-thTo obtain a corresponding first electrical signal, e.g. the amplitude of the first laser signal is greater than or equal to MH-thWhen the first electric signal is the high-level electric signal corresponding to the digital signal 1; the amplitude of the first laser signal is less than or equal to ML-thThe first electrical signal is an electrical signal at a low level corresponding to the digital signal 0. As long as the first laser signal is converted into the corresponding first electrical signal according to the preset carrier parameter in the first laser signal, this embodiment does not limit this.
Step 103: and acquiring first communication data corresponding to the first electric signal.
In this step, a processor such as a single chip microcomputer in the wireless headset can acquire corresponding first communication data according to the first electric signal sent by the laser receiving module. For a specific obtaining manner of the first communication data, the same or similar manner as that in the prior art may be adopted, for example, when the first communication data is composed of binary digital signals of 0 and 1, the processor may obtain corresponding digital signals of 0 and 1 according to the low-level and high-level electrical signals in the first electrical signal, so as to obtain the first communication data corresponding to the first electrical signal. The present embodiment does not set any limit to this.
Specifically, in this step, the processor in the charging box may directly obtain first communication data corresponding to the first electrical signal sent by the laser receiving module, that is, the processor may directly receive the first electrical signal sent by the demodulator in the laser receiving module; as shown in fig. 2, the processor may also receive the amplified first electrical signal sent by the demodulator in the laser receiving module through the signal amplifier, that is, the processor may obtain the corresponding first communication data by using the amplified first electrical signal. The present embodiment does not set any limit to this.
It can be understood that the first communication data acquired in this step may be data sent by the charging box by using wireless laser communication, and specific data types of the first communication data, that is, data types sent by the charging box to the wireless headset, may be set by a designer according to a practical scene and a user requirement, and if the charging box only needs to send a wireless headset control instruction to the wireless headset, the first communication data may only include a wireless headset control instruction; when the charging box further needs to send other data such as the information of the electric quantity of the charging box to the wireless headset, the first communication data may further include corresponding data information, and this embodiment does not limit this.
Correspondingly, the step can also include the step of judging whether the first communication data is a wireless earphone control instruction or not; when the first communication data are used as the wireless earphone control instruction, the processor can execute corresponding operation according to the wireless earphone control instruction corresponding to the decoded data, and the charging box can control the wireless earphone through wireless laser communication. The specific type of the wireless earphone control instruction can be set by a designer according to a practical scene and user requirements, if the charging box needs to control the wireless earphone to keep a dormant state in the charging process, the wireless earphone control instruction can comprise a dormant instruction, and the charging box can control the wireless earphone to enter the dormant state by sending the dormant instruction; after charging is finished or when the charging box cover is opened, if the charging box needs to control the wireless earphone to perform Bluetooth pairing, the wireless earphone control instruction can comprise a Bluetooth pairing instruction, so that the wireless earphone performs Bluetooth pairing operation according to the Bluetooth pairing instruction; in the charging process, if the charging box needs to acquire the battery electric quantity information of the wireless earphone, the wireless earphone control instruction can comprise an electric quantity report instruction, so that the wireless earphone sends the battery electric quantity information of the wireless earphone to the charging box through wireless laser communication according to the electric quantity report instruction; the wireless headset control instruction may further include other control instructions such as an upgrade file sending instruction and a ble broadcast start instruction, as long as the wireless headset may execute a corresponding operation according to the wireless headset control instruction corresponding to the first communication data, which is not limited in this embodiment.
It should be noted that, the charging box in this embodiment may send the first communication data to the wireless headset through the first laser signal, that is, the charging box and the wireless headset may perform wireless laser communication, and the wireless laser communication is a novel light source, and has the characteristics of high brightness, strong directivity, good monochromaticity, strong coherence, large output data amount, strong stability, and the like, and has a better characteristic than ordinary light, that is, monochromaticity; the divergence angle of the laser beam is small, the energy is concentrated in a small range, and the receiver can obtain the power density which is higher than that of microwaves by several orders of magnitude; compared with infrared communication, the wireless laser communication in the embodiment has higher reliability and is more stable. In addition, the wireless laser communication has the characteristics of high modulation rate, wide frequency band, no occupation of frequency spectrum resources, no need of an authorized license, rapid link deployment, low cost, strong transmission confidentiality, large information capacity and the like; compared with bluetooth and other wireless communication methods, the configuration cost of the wireless laser communication in the embodiment is lower.
In the embodiment of the invention, the wireless communication between the wireless earphone and the charging box is realized by utilizing the laser communication technology, the influence of a communication mode for increasing a contact point on the appearance design of the wireless earphone is avoided, the problem that the connection risk between the wireless earphone and the charging box is increased in multiples is solved, and the communication reliability and the user experience are improved; compared with Bluetooth communication and infrared communication, the configuration cost is lower and the reliability is higher.
Based on the above embodiments, please refer to fig. 3, and fig. 3 is a flowchart of another communication method according to an embodiment of the present invention. The method is applied to the wireless headset and can comprise the following steps:
step 201: and acquiring the second communication data.
The second communication data in this step may be data that the wireless headset needs to send to the charging box by using the laser emitting module set by the wireless headset itself. The specific data type of the second communication data, that is, the data type sent by the wireless headset to the charging box, may be set by a designer according to a practical scenario and a user requirement, for example, the second communication data may include a charging box control instruction sent by the wireless headset to the charging box. For example, the earphone electric quantity display instruction, the charging start instruction, the charging stop instruction and the like; the second communication data may also include other data such as upgrade data of the charging box, which is not limited in this embodiment.
It can be understood that, in this step, the specific manner in which the processor, such as the single chip microcomputer, in the wireless headset acquires the second communication data may be set by the designer according to the practical scenario and the user's requirements. If the second communication data is a charging box control instruction for controlling the charging box, the processor in the wireless headset can acquire a corresponding charging box control instruction according to an instruction sent by the terminal connected in a matched manner; for example, when the user needs the indicator light of the charging box to display the electric quantity information of the headset, the corresponding signal can be sent to the wireless headset in the pairing connection through the terminal, so that the processor in the wireless headset can acquire the electric quantity display instruction of the headset. The processor in the wireless earphone can also obtain a charging box control instruction according to logic judgment; for example, the processor may retrieve the charge start instruction when it determines that the battery level of the wireless headset is below a threshold. The present embodiment does not limit this to any way as long as the processor in the wireless headset can obtain the charging box control instruction.
It should be noted that, for the specific type setting of the charging box control instruction, the setting may be set by a designer according to a practical scene and a user requirement, for example, when the wireless headset needs to control the charging box to start and end charging the wireless headset, the charging box control instruction may include a charging start instruction and a charging stop instruction; when the wireless earphone needs to control the charging box to display the battery power of the wireless earphone, the charging box control instruction can comprise an earphone power display instruction; the charging box control instruction may further include other control instructions such as a charging box electric quantity display instruction, as long as the charging box can execute corresponding operations according to the charging box control instruction received through wireless laser communication, and this embodiment does not limit this.
Correspondingly, as shown in fig. 4, reference numeral 1 may be a laser emitting module and a laser receiving module of a right earphone, reference numeral 2 may be a laser hole of the right earphone, reference numeral 3 may be a laser beam (i.e., a first laser signal or a second laser signal) between the right earphone and the charging box, reference numeral 4 may be a laser hole of a right ear chamber of the charging box, and reference numeral 5 may be a laser emitting module and a laser receiving module of the right ear of the charging box; reference numeral 6 can be for the laser emission module and the laser receiving module of left earphone, and reference numeral 7 can be the laser hole of left earphone, and reference numeral 8 can be for left earphone and the laser beam (first laser signal or second laser signal) between the box that charges, and reference numeral 9 can be the left ear storehouse laser hole of the box that charges, and reference numeral 10 can be the left ear laser emission module and the left ear laser receiving module of the box that charges. That is to say, the wireless earphone may be a left earphone or a right earphone in a binaural wireless earphone, and if the wireless earphone is the left earphone, after the left earphone is placed in the charging box, the laser receiving module of the left earphone may receive the laser beam (i.e. the first laser signal) emitted from the laser hole of the left ear bin by the left earphone laser emitting module of the charging box of the left earphone; the laser beam (second laser signal) that the laser emission module of left earphone can pass through the laser hole of left earphone to the left ear storehouse laser hole transmission of box that charges makes the left earphone laser receiving module of box that charges can follow left ear storehouse laser hole and receive this laser beam.
