It will be further understood that terms, such as those defined in commonly used dictionaries, should be interpreted as having a meaning that is consistent with their meaning in the context of the relevant art and will not be interpreted in an idealized or overly formal sense unless expressly so defined herein.
Techniques, methods, and apparatus known to those of ordinary skill in the relevant art may not be discussed in detail but are intended to be part of the specification where appropriate.
The disclosed embodiments provide a wireless headset assembly, as shown in fig. 1, comprising a first headset 110 and a second headset 120, each headset comprising a bluetooth module 101 and a processor 102, the bluetooth module 101 of each headset being configured, in conjunction with fig. 1 and 2, to: detecting whether the headset maintains a bluetooth connection with another headset (S201), and determining a Received Signal Strength Indication (RSSI) of the headset (S202); the processor 102 of the earphone or of another earphone is configured to: in the case where the headset remains bluetooth-connected to the other headset, it is determined whether the representative value of RSSI of the headset is less than a first threshold value (S203), and if so, it is determined that the headset is lost (S204).
It is understood that, the two bluetooth modules 101 of the two earphones can determine their RSSI, and the two earphones can determine whether each of the two earphones is lost according to the RSSI representative value, for convenience of explanation, the lost earphone is the first earphone 110, and for convenience of explanation, the processor 102 of the first earphone 110 or the second earphone 120 can determine whether the first earphone 110 is lost based on the RSSI determined by the bluetooth module 101 of the first earphone 110 when the bluetooth module 101 of the first earphone 110 or the second earphone 120 detects that the two earphones keep bluetooth connection, that is, the processor 102 of the first earphone 110 can obtain the RSSI of the first earphone 110, the processor 102 of the second earphone 120 can obtain the RSSI of the first earphone 110 through the connection between the two earphones, and by comparing the RSSI representative value of the first earphone 110 with the first threshold value, when the representative RSSI value is less than the first threshold, it indicates that the bluetooth connection between the first headset 110 and the second headset 120 is weak at that time, i.e., the table determines that the first headset 110 has been lost. The same as the above case when the lost earphone is the second earphone 120, and the description of the present application is omitted here. According to the mode, whether the earphone is lost or not can be judged in time through the Bluetooth connection between the two earphones, so that a user can know the condition that the earphone is lost in time, and the technical problem that the wireless earphone is easy to lose in the prior art is solved.
It is understood that while the first headset 110 and the second headset 120 maintain the bluetooth connection, the RSSI determined by the bluetooth module 101 of the first headset 110 and the second headset 120 is a valid RSSI, and the processors 102 of the two headsets can make a decision based on the valid RSSI and determine a valid decision result.
In some embodiments, the processor 102 of the headset or another headset is further configured to: any one of an average value, a maximum value, and a minimum value of the plurality of RSSIs in a case where the earphone is connected to the other earphone by bluetooth is determined as the representative value of the RSSIs of the earphone. It is to be understood that the representative value of the RSSI of the headset is not limited, and may be the RSSI of the headset at a certain time when two headsets are bluetooth connected, or may be an average value, a maximum value, or a minimum value of the RSSI of the headset acquired in a certain time period when two headsets are bluetooth connected. The RSSI representative value is obtained, so that a more accurate RSSI value can be obtained, and the influence on the accuracy of the RSSI value due to the interference of a wireless channel is avoided.
In some embodiments, as shown in fig. 2, in case the headset is lost, a vocalization indicating voice signal from the user is received via the microphone of another headset and transmitted to the headset to be vocalized (S205). It can be understood that, when the lost earphone is the first earphone 110, the microphone of the second earphone 120 receives the sounding indication voice signal of the user and transmits the sounding indication voice signal to the first earphone 110, and the first earphone 110 and the second earphone 120 can transmit signals based on wireless communication or bluetooth connection, which is not specifically limited in this disclosure, and signal transmission between the first earphone 110 and the second earphone 120 can be implemented, so that the first earphone 110 can sound, for example, the first earphone 110 sends a sound effect of "i am at this" or prompting music, so as to prompt the user of a specific position of the first earphone 110, which is convenient for the user to find. In addition, the first earphone 110 may further be provided with a vibration module, and the second earphone 120 may transmit an indication action signal of the user to the first earphone 110, so that the first earphone 110 may vibrate based on the indication action signal to prompt the user. The same as the above case when the lost earphone is the second earphone 120, and the description of the present application is omitted here.
In some embodiments, as shown in fig. 3, the bluetooth module 101 of each headset is further configured to: determining interfered related information of each frequency point of the earphone; each headset further comprises a memory 103, the memory 103 further configured to: under the condition that the earphone is connected with another earphone in a Bluetooth mode, the determined information related to the interference of each frequency point of the earphone is stored (S301), namely, the memory 103 can store the information related to the interference of each frequency point of the earphone when the two earphones are connected in the Bluetooth mode; the processor 102 of the earphone or of another earphone is further configured to: when the earphone is disconnected from another earphone by bluetooth, it is determined whether the earphone is lost based on the information related to interference of each frequency point before the earphone is disconnected from the bluetooth (S302).
It can be understood that, due to factors affecting disconnection of bluetooth connections between two earphones, besides that the distance between the two earphones is too large, there is also a case where the two earphones are located in an environment with too large interference, resulting in disconnection of bluetooth connections between the two earphones, for example, the two earphones are located in places with extremely large traffic, such as train stations, airports, and sunclubs, and disconnection of bluetooth connections between the two earphones does not represent that there is a certain condition that the earphones are lost. The memory 103 of the earphone stores the interfered related information of each frequency point at a certain moment before the disconnection of the two earphones or in a certain time period before the disconnection of the two earphones, so that whether the disconnection of the two earphones is caused by excessive interference of the environment can be further determined, and whether the earphones are lost can be further determined.
In some embodiments, continuing with fig. 4(a) and fig. 4(b), the interfered related information of each frequency point includes the available frequency points in the frequency hopping list and/or the RSSI of the air interference signal of each frequency point, that is, by determining the interfered related information of each frequency point, the number of available frequency points in the frequency hopping list can be determined (S401) and the RSSI of the air interference signal of each frequency point can be determined (S411). Accordingly, the above determining whether the headset is lost (S302) based on the information related to interference of each frequency point before the headset disconnects the bluetooth connection includes: when the number of available frequency points in the frequency hopping list is larger than a second threshold value (S402), judging that the earphone is lost (S403); and/or determining that the earphone is lost (S413) when the RSSI of the air interference signal of the frequency bin of the number of the third threshold value is less than the fourth threshold value (S412). It can be understood that, before the two earphones are disconnected from the bluetooth connection, the number of available frequency points in the frequency hopping table stored in the memory 103 exceeds the second threshold, and/or the RSSI of the air interference signal of a certain number of frequency points is smaller than the fourth threshold, which indicates that the interference received before the disconnection of the two earphones is less, and the disconnection of the two earphones cannot be caused by the environmental interference, so that the bluetooth disconnection caused by the loss of the earphones is determined, that is, the judgment result is that the earphones are lost.
In some embodiments, the interfered related information of each frequency point before the bluetooth connection is disconnected includes interfered related information of each frequency point at a certain time or within a certain time period before the bluetooth connection is disconnected, and it can be understood that the interfered related information may be acquired at a certain time or within a certain time period when the bluetooth connection is disconnected.
The disclosed embodiment also provides a wireless communication system, as shown in fig. 5, the wireless communication system includes the above-mentioned wireless headset assembly and another device 130, the first headset 110 of the two headsets is configured to establish a bluetooth connection with the another device 130, and the second headset 120 of the two headsets is configured to listen to a bluetooth signal from the another device 130. The other device 130 may be an electronic device such as a handheld terminal, a notebook computer, etc., and the application is not limited in this respect.
It is understood that after the first headset 110 and the other device 130 establish the bluetooth connection, the first headset 110 may indirectly or directly transmit the bluetooth address of the other device 130, the encryption parameters of the bluetooth connection between the first headset 110 and the other device 130, and other communication information to the second headset 120, so that the second headset 120 listens for and receives the audio signal transmitted by the other device 130. The direct mode includes a wireless mode such as bluetooth, bluetooth low energy, etc., and the indirect mode includes relaying communication information to the second headset 120 through the charging box and the other device 130.
In some embodiments, in the event that the first earpiece 110 or the second earpiece 120 is determined to be lost, a vocalization indicating voice signal of the user is received via the microphone of the other earpiece and transmitted to the lost earpiece or the other device 130 to cause the lost earpiece or the other device 130 to vocalize.
It will be appreciated that in the event that the first earphone 110 or the second earphone 120 is determined to be lost, the microphone of the non-lost earphone can receive the vocalization instruction voice signal emitted by the user and transmit it to the lost earphone or another device 130 to prompt the user with the vocalization of the lost earphone or another device 130. For example, when the lost headset is the first headset 110, the second headset 120 receives the sounding indication voice signal of the user and transmits to the first headset 110 or the other device 130 to sound the first headset 110 or the other device 130. If the first earphone 110 is lost near the user, the sounding of the first earphone 110 can directly prompt the user about the position of the first earphone 110, which is convenient for the user to find. The same is true when the lost earphone is the second earphone 120, and the description of the present application is omitted here.
The disclosed embodiment also provides another wireless communication system, as shown in fig. 5 and fig. 6, the wireless communication system includes a first earphone 110, a second earphone 120 and another device 130, the first earphone 110 and the second earphone 120 each include a bluetooth module 101 and a processor 102, the first earphone 110 is configured to establish a bluetooth connection with the another device 130, and the second earphone 120 is configured to listen for a bluetooth signal from the another device 130. Wherein the bluetooth module 101 of each headset is configured to: detecting a bluetooth connection condition of the headset with the other device 130 (S610), and determining a representative value of a Received Signal Strength Indication (RSSI) of the headset for the bluetooth connection (S612 or S622); the processor 102 of the first earpiece 110 or the second earpiece 120 is configured to: in a case where it is detected that the another device 130 maintains the bluetooth connection with both the first headset 110 and the second headset 120 (S611), determining a representative value of the RSSIs of both bluetooth connections and determining whether or not it is less than a fifth threshold (S613), and if so, determining that the another device 130 is lost (S614); and in the case where it is detected that the another device 130 maintains the bluetooth connection with one of the first and second headsets 110 and 120 (S621), determining a representative value of RSSI of the bluetooth connection and determining whether or not it is less than a sixth threshold value (S623), and if so, determining that the another device 130 is lost (S624).
It is understood that, in the case that the first earphone 110 establishes a bluetooth connection with the other device 130, and the second earphone 120 acquires the audio signal transmitted by the other device 130 by listening, the bluetooth modules 101 of the first earphone 110 and the second earphone 120 can both detect the received signal strength indication received by the bluetooth thereof, and when the first earphone 110 and the second earphone 120 maintain the bluetooth connection with the other device 130, the processor 102 of the first earphone 110 or the second earphone 120 can both determine whether the RSSI representative value of the bluetooth connection is smaller than the fifth threshold value, and if so, determine that the other device 130 is lost.
In the case where the other device 130 is bluetooth connected to only one of the first headset 110 or the second headset 120, the processor 102 of the first headset 110 or the second headset 120 can determine that the other device 130 is lost by determining a representative value of RSSI of the bluetooth connection and determining whether the representative value is less than a sixth threshold value, and if so. It should be noted that, if the other device 130 is bluetooth connected to the first headset 110 only, the processor 102 of the second headset 120 can obtain the RSSI representative value of the bluetooth connection between the first headset 110 and the other device 130, and the RSSI representative value can be sent from the first headset 110 to the second headset 120 through wireless transmission or other methods, so that the second headset 120 bluetooth connected to the first headset 110 can also determine the loss of the other device 130.
In some embodiments, as shown in fig. 7, the bluetooth modules 101 of the first and second headsets 110, 120 are configured to: detecting a bluetooth connection of the headset with another headset and the other device 130 (S710), and determining an RSSI of the bluetooth connection (S712 or S722). In particular, the processor 102 of the headset or another headset is configured to: in the case where it is detected that the headset maintains the bluetooth connection with the other headset and the other device 130 (S711), a representative value of the RSSI of the two bluetooth connections is determined (S712) and it is determined whether or not it is less than a seventh threshold (S713), and if so, it is determined that the headset is lost (S714). And the bluetooth modules 101 of the first and second headsets 110, 120 are further configured to: in the case where it is detected that the headset maintains a bluetooth connection with one of another headset and the another device 130 (S721), a representative value of RSSI of the bluetooth connection is determined (S722) and it is determined whether or not it is less than an eighth threshold value (S723), and if so, it is determined that the headset is lost (S724).
To further understand, for example, when the first earphone 110 is the earphone, in a case that the first earphone 110 is bluetooth-connected to the second earphone 120 and the other device 130, respectively, the processor 102 of the first earphone 110 or the second earphone 120 can obtain the representative value of the RSSI of the two bluetooth connections and determine the representative value to obtain the loss condition of the first earphone 110; in the case where the first headset 110 maintains a bluetooth connection with one of the second headset 120 or the other device 130, the processor 102 of the first headset 110 or the second headset 120 can obtain and determine the representative value of RSSI of the bluetooth connection to obtain a loss condition of the first headset 110. When the second earphone 120 is the earphone, the same situation as the above case is used, and the description of the present application is omitted.
In some embodiments, the RSSI representative value of a single bluetooth connection is any one of an average value, a maximum value and a minimum value of the RSSI of the bluetooth connection over a period of time, and the RSSI representative value of two bluetooth connections is an average value or a maximum value of the RSSI representative values of the respective bluetooth connections. It is to be understood that the representative value of the RSSI of the bluetooth connection is not limited, and when the representative value of the RSSI of a single bluetooth connection is, any one of an average value, a maximum value and a minimum value of the RSSI of the bluetooth connection over a period of time may be used; when the RSSI representative values of two bluetooth connections are taken, the RSSI representative values of the two bluetooth connections are taken as any one of an average value and a maximum value of the RSSI representative values of the respective bluetooth connections. The RSSI representative value is obtained, so that a more accurate RSSI value can be obtained, and the influence on the accuracy of the RSSI value due to the interference of a wireless channel is avoided.
In some embodiments, in the case that it is determined that the other device 130 is lost, the first earphone 110 or the second earphone 120 is made to sound, it is understood that, after the processor 102 of the first earphone 110 or the second earphone 120 determines that the other device 130 is lost, the first earphone 110 and the second earphone 120 can sound to remind the user that the other device 130 is lost, so as to prompt the user in time; in the event that the first earphone 110 or the second earphone 120 is lost, the vocalization indicating voice signal is received via the microphone of the not-lost earphone and transmitted to the lost earphone or the other device 130 so as to enable the lost earphone or the other device 130 to vocalize, it is understood that, after the processor 102 of the first earphone 110 or the second earphone 120 determines that the earphone is lost, the vocalization indicating voice signal sent by the user is received by the microphone of the not-lost earphone and transmitted to the lost earphone or the other device 130 so as to prompt the user through the other device 130 or the user performs a location finding on the earphone through the vocalization of the lost earphone.
In some embodiments, as shown in fig. 8, the bluetooth module 101 of each headset is further configured to: and determining the interfered related information of each frequency point of the earphone. Each headset further includes a memory 103 (shown in fig. 1 and 3), the memory 103 being configured to: and storing the determined information related to the interference of each frequency point of the headset under the condition that the other device 130 is in Bluetooth connection with the headset (S801 or S802). The processor 102 of the first earpiece 110 or the second earpiece 120 is further configured to: when the other device 130 disconnects the bluetooth connection to the two earphones (S803), it is determined whether the other device 130 is lost based on the information on the interfered frequency points of the two earphones before the bluetooth connection is disconnected.
It can be understood that, due to factors affecting the bluetooth disconnection between the two earphones and the other device 130, besides the distance between the two earphones and the other device 130 is too large, there is also a case where the bluetooth connection between the other device 130 and the two earphones is disconnected due to too large environmental interference, for example, the other device 130 is in a place with a very large stream of people, such as a train station, an airport, and a concert, and the bluetooth disconnection between the other device 130 and the two earphones does not necessarily represent a case where the other device 130 is lost. By storing the interfered information of each frequency point at a certain time or within a certain time period before the two earphones are disconnected with the other device 130 through the memory 103 of the earphones, it can be further determined whether the other device 130 is disconnected with the two earphones due to excessive interference of the environment, so as to further determine whether the other device 130 is lost.
In some embodiments, as shown in fig. 8, the interfered related information of each frequency point includes an available frequency point in the frequency hopping list and/or an RSSI of an air interference signal of each frequency point, that is, by determining the interfered related information of each frequency point, the number of available frequency points in the frequency hopping list can be determined (S811) and the RSSI of the air interference signal of each frequency point can be determined (S821).
