The embodiments described below with reference to the accompanying drawings are illustrative only for the purpose of explaining the present invention, and are not to be construed as limiting the present invention.
In the description of the present invention, the meaning of a plurality of means is one or more, the meaning of a plurality of means is two or more, and larger, smaller, larger, etc. are understood as excluding the number, and larger, smaller, inner, etc. are understood as including the number. If the first and second are described for the purpose of distinguishing technical features, they are not to be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated or implicitly indicating the precedence of the technical features indicated.
Referring to fig. 1, the method of the embodiment of the present invention includes the following steps: the earphone and the mobile device are connected in a Bluetooth mode, the main earphone and the auxiliary earphone are connected in a main-auxiliary mode, and the auxiliary earphone monitors data of communication between the main earphone and the mobile device through receiving aerial signals; dividing a communication frequency band into two non-overlapping frequency bands according to a preset value, wherein the two non-overlapping frequency bands correspond to a first frequency point and a second frequency point; the method comprises the following steps of communicating at a first frequency point and a second frequency point based on a preset rule, wherein the preset rule comprises the following steps: and in the mobile equipment communication stage, the main earphone communicates with the mobile equipment at a first frequency point and communicates with the auxiliary earphone at a second frequency point. The division of the frequency bands of the first frequency point and the second frequency point in the communication frequency band, referring to fig. 3, may be parallel but the frequency band intervals do not overlap.
Referring to fig. 2, in an embodiment of the present invention, a communication method includes: judging whether the current communication stage is a mobile equipment communication stage; if the mobile equipment is in the communication stage, the main earphone and the mobile equipment communicate at the first frequency point and communicate with the auxiliary earphone at the second frequency point; if not, the communication stage of the main earphone and the auxiliary earphone is the communication stage of the main earphone and the auxiliary earphone, and the main earphone and the auxiliary earphone are simultaneously communicated at the first frequency point and the second frequency point.
In the embodiment of the invention, in the communication stage of the mobile equipment, after the main earphone receives the data sent by the mobile equipment, the main earphone responds to the mobile equipment at the first frequency point and simultaneously forwards the relevant data to the auxiliary earphone at the second frequency point. The auxiliary earphone monitors the communication equipment of the main earphone and the mobile equipment at the first frequency point and receives the data forwarded by the main earphone at the second frequency point. The data in communication includes audio data, control data, and the like.
In this embodiment, with one complete transmission and reception process as one Frame, referring to fig. 4, RX indicates receiving data once, TX indicates transmitting data once, Frame0 indicates a mobile device communication Frame, and Frame1 indicates a headset communication Frame. During a first time period of a first Frame (i.e., Frame0 in fig. 4), the mobile device transmits data. In a first time period of the Frame0, for a first frequency point, the main earphone receives data sent by the mobile device through blue ear connection, and the auxiliary earphone monitors an air signal and receives data sent by the mobile device; at the second frequency point, the main earphone and the auxiliary earphone do not act. It can be understood that the data error or loss is easily occurred when the auxiliary earphone directly monitors the air signal receiving data, in this case, it is necessary to wait for the data forwarded by the main earphone and then make the next operation, such as playing audio. In a second time period of the Frame0, for the first frequency point, the primary earphone already receives the data, and sends a response to the data of the Frame to the mobile equipment, the mobile equipment receives the response, and the secondary earphone monitors the response signal; for the second frequency point, the main earphone transmits the data of the frame received at the first frequency point, and the auxiliary earphone receives the data transmitted by the main earphone. The main earphone and the mobile equipment appoint the end of the communication stage of the mobile equipment in communication data, after the auxiliary earphone monitors the data of the end of the stage or receives the relevant data forwarded by the main earphone, the auxiliary earphone and the mobile equipment enter the communication stage of the main earphone and the auxiliary earphone. The second Frame of fig. 4 (i.e., Frame1) is a headset communication Frame when the mobile device is not engaged in communication. In a first time period of the frame, the main earphone transmits data at two frequency points, and the two frequency points of the auxiliary earphone receive data; in the second time period of the frame, the auxiliary earphone transmits data at two frequency points, and the two frequency points of the main earphone receive data. It can be understood that the master earphone can also receive data at both the two frequency points in the first time period and transmit data in the second time period; and the auxiliary earphone transmits data at two frequency points in the first time period and receives data in the second time period. Therefore, compared with the traditional wireless double-earphone communication method, the embodiment of the invention can simultaneously carry out the communication between the main earphone and the mobile equipment and the communication between the main earphone and the auxiliary earphone, thereby improving the communication bandwidth of the whole true wireless double-earphone system.
In other embodiments of the present invention, in the headset communication frame, the primary and secondary headsets do not distinguish the frequency bands of the first frequency point and the second frequency point, but process them together. The master earphone sends data in a first time period of an earphone communication frame, and receives data in a second time period; accordingly, the sub-headset receives data during a first time period and transmits data during a second time period of the headset communication frame. It is understood that the master earphone may also be configured to receive data during a first time period and transmit data during a second time period of the earphone communication frame; the sub-headset accordingly transmits data in a first time period and receives data in a second time period. Although in these embodiments, only one data can be transmitted in the same time period, the bandwidth is larger than that of data transmission, and the data transmission is not slower than that of two separate frequency points.
In fig. 4, the mobile device communication phase and the headset communication phase are only one frame as an example, and it is understood that the mobile device communication phase and the headset communication phase are not limited to one frame or a fixed number of frames, and the beginning and the end of each phase can be agreed by communication data. For example: the mobile equipment and the main earphone are communicated, the communication stage end information of the mobile equipment is sent to the main earphone, the main earphone receives the information and forwards the information to the auxiliary earphone, and the mobile equipment communication stage is ended by the main earphone, the main earphone and the auxiliary earphone, and the communication stage of the main earphone and the auxiliary earphone is started; the communication of the main earphone and the auxiliary earphone is completed, the main earphone simultaneously sends the information of the end of the earphone communication stage at the first frequency point and the second frequency point, the communication stage of the main earphone and the auxiliary earphone is switched to the communication stage of the mobile equipment, and the mobile equipment can still be connected with the first frequency point through Bluetooth to receive the information even though the mobile equipment does not participate in the communication, so that the communication can be participated again.
In fig. 4, for any one of the main and sub earphones, only transmitting or receiving data is performed during the same period of a single frame; wherein, the data sending process is as follows: combining the data of the first frequency point and the second frequency point according to a preset frequency band and then transmitting the data through a single radio frequency circuit; when receiving data, the single radio frequency circuit receives radio frequency signals of all communication frequency bands, and splits the signals into two sections which are respectively handed to the first frequency point and the second frequency point for processing. The single radio frequency circuit can simplify the processing, save the space, save the hardware cost and reduce the subsequent power consumption.
In the wireless headset according to the embodiment of the present invention, the main and sub-headsets have the same structure, as shown in fig. 5, and include: the modem unit 100 is configured to modulate and demodulate communication data, and includes a first modem unit 110 and a second modem unit 120, where the first modem unit 110 is configured to modulate and demodulate data of a first frequency point, and the second modem unit 120 is configured to modulate and demodulate data of a second frequency point; the baseband unit 200 is configured to control a receiving and sending timing sequence, and temporarily store data to be sent to the modem unit 100 and data demodulated by the receiving modem unit 100; and the radio frequency unit 300 is configured to receive a radio frequency signal sent by the mobile device or another headset, and send the radio frequency signal to the mobile device or another headset.
Referring to fig. 6, in the wireless headset of the present embodiment, the main and sub-headsets further include: the synchronization unit 400 is configured to combine data of the modem units according to a preset frequency band or split the received signal according to the preset frequency band and send the signal to the corresponding modem unit.
Referring to fig. 6, first, a bluetooth connection is established between a main headset and a mobile device, and a secondary headset listens to communication data between the main headset and the mobile device in the air. The primary and secondary earphones receive signals through the radio frequency unit 300, and the synchronization unit 400 disassembles the signals according to a preset frequency band and delivers the signals to corresponding modulation and demodulation units for processing.
In the communication stage of the mobile device, the signal in the frequency band of the first frequency point is considered as the communication between the main earphone and the mobile device, the synchronization unit 400 sends the signal in the corresponding frequency band to the first modem unit 110 for demodulation, and sends the demodulated data to the baseband unit 200, and the baseband unit 200 controls the timing sequence and processes the data accordingly. Upon receiving the data, the primary earpiece modulates the data in the second modem unit 120 for forwarding to the secondary earpiece while modulating the reply signal in the first modem unit 110. The synchronization unit 400 combines the corresponding modulation signal in the first modem unit 110 and the modulation signal in the second modem unit 120 according to a predetermined frequency band, and sends the combined modulation signal to the mobile device and the sub-headset through the radio frequency unit 300. Referring to fig. 3, the mobile device does not process the data of the frequency band of the second frequency point, and only receives the data of the frequency band of the first frequency point, i.e. the response of the main headset. The auxiliary earphone receives the signal of the main earphone through the radio frequency unit 300, and after the signal is processed by the synchronization unit 400, the signal of the first frequency point is monitored, and the signal of the second frequency point is demodulated by the second modulation and demodulation unit 120, so that the data forwarded by the main earphone is obtained.
In the earphone communication stage, signals in the frequency band of the first frequency point and signals in the frequency band of the second frequency point are considered to be communication between the main earphone and the auxiliary earphone. In some embodiments of the present invention, the communication data in the headset communication stage is still processed separately in two frequency bands, and the specific flow is as follows. If the master earphone transmits data first, data a is modulated in the first modem 110 and data B is modulated in the second modem 120 at the same time. The synchronization unit 400 combines the modulated data according to a preset frequency band, and then transmits the combined data through the radio frequency unit 300. The sub-earphone receives the signal, the signal is correspondingly disassembled through the radio frequency unit 300 and then respectively sent to the first modulation and demodulation unit 110 and the second modulation and demodulation unit 120 for demodulation, the first modulation and demodulation unit 110 demodulates the signal to obtain data a, and the second modulation and demodulation unit 120 demodulates the signal to obtain data B. The sub-headset performs corresponding processing on the data a and the data B under the control of the baseband unit 200. The sub-earphone transmits data, which is modulated simultaneously in the first modem unit 110 and the second modem unit 120, combined by the synchronization unit 400, and finally transmitted by the radio frequency unit 300; after the main earphone receives the signal, the synchronization unit 400 divides the signal into two sections, which correspond to the frequency bands of the first frequency point and the second frequency point, respectively, and sends the two sections to the corresponding modems for processing.
In other embodiments of the present invention, the communication data in the headset communication stage is not processed separately in two frequency bands, and the specific flow is as follows. Referring to fig. 5, if the master earphone transmits data first, data a is modulated only by the first modem unit 110 and transmitted through the rf unit 300. It should be understood that the operating frequency band of the first modem unit 110 includes the frequency band of the first frequency point and the frequency band of the second frequency point. The sub-headphone receives data through the radio frequency unit 300, and also performs demodulation using only the first modem unit 110 to obtain data a. It is understood that the primary and secondary earphones may also select the second modem unit 120 to perform modem of the communication data. In these embodiments, although only one data can be transmitted in the same time period in the earphone communication phase, the data transmission is not slower than that of two separate frequency points due to the large bandwidth.
In other embodiments of the present invention, the data modulated by the modem units is transmitted and received through the corresponding radio frequency units, that is: after the first modem unit 110 modulates the data, the data is sent through the first radio frequency unit; the first radio frequency unit receives data of a first frequency point and sends the data to the first modulation and demodulation unit for demodulation; after the second modulation and demodulation unit 120 modulates the data, the data is sent through the second radio frequency unit; and the second radio frequency unit receives the data of the second frequency point and sends the data to the second modulation and demodulation unit for demodulation. The two radio frequency units are independent of each other and each include a radio frequency circuit and an antenna. It will be appreciated that in these embodiments, no synchronization unit is required; one earphone does not need to limit that two working frequency points must simultaneously send or receive data in the same time period.
The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge of those skilled in the art without departing from the gist of the present invention.
