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 TWS dual wireless headset searching method according to the present invention, the method including:
s11: detecting whether the first wireless earphone enters a falling state, and if so, entering S12;
the TWS double-wireless earphone is two earphones, namely a left earphone and a right earphone. The left earphone and the right earphone adopt an equivalent design, the TWS double-wireless earphone searching method is suitable for any earphone, and after any earphone falls within a certain distance range, the falling direction can be detected by the other earphone, so that the user is assisted to finally find the lost earphone. Different with artifical purposeless searching when earphone falls among the prior art, in this application, first wireless earphone can realize automatic positioning with the cooperation of second wireless earphone when falling to make things convenient for the user to carry out purposeful searching according to locating information, increased and look for efficiency.
In the application, for any earphone, the earphone can actively detect whether the earphone enters a falling state in real time or periodically or passively when receiving a positioning instruction. The active real-time or periodic triggering means that the first wireless earphone triggers in real time or periodically through a clock to detect whether the first wireless earphone enters a falling state; the passive receiving of the positioning instruction refers to that the user triggers the two wireless earphones of the lost TWS through the second wireless earphone or other terminals which are not lost to detect whether the first wireless earphone enters a falling state.
There are various ways to specifically determine whether the first wireless headset enters the falling state, and the application starts from the characteristics of the TWS dual wireless headset when falling, for example, the acceleration when falling to the ground is different from the acceleration when running normally and walking, and the application is not limited in particular.
S12: sending a search signal to a second wireless headset;
s13: receiving positioning data sent by the second wireless earphone after receiving the searching signal;
for convenience of introduction, the fallen earphone is referred to as a first wireless earphone in the present application, after detecting that the first wireless earphone enters the falling state, the first wireless earphone can send a search signal to a second wireless earphone (i.e. another earphone) (regardless of whether the second wireless earphone is also in the falling state) through but not limited to bluetooth, and after receiving the search signal, the second wireless earphone can send positioning data for positioning to the first wireless earphone through but not limited to bluetooth.
S14: and determining the positioning information of the first wireless earphone relative to the second wireless earphone according to the positioning data, and sending the positioning information to the second wireless earphone so that the second wireless earphone prompts the positioning information.
After the first wireless earphone receives the positioning data, the positioning information of the first wireless earphone relative to the second wireless earphone is determined according to the positioning data, the positioning information can be sent to the second wireless earphone through the Bluetooth but is not limited to the Bluetooth, and the second wireless earphone prompts the positioning information after receiving the positioning information. Specifically, the positioning information may include a position and/or a distance, and the user may narrow the search range of the first wireless headset by using the position and/or the distance, so that the search is more convenient for the user.
It should be noted that, in practical applications, the second wireless headset may periodically or in real time send the positioning data to the first wireless headset, so that the first wireless headset also receives the positioning data in real time or periodically and determines the positioning information in real time or periodically according to the positioning data, and the second wireless headset also searches the first wireless headset in real time or periodically according to the prompted positioning information. The positioning information prompted by the second wireless earphone is changed in real time or periodically in the walking searching process of the user, and therefore the searching accuracy of the user for the first wireless earphone is improved.
In addition, the prompt may be a light alarm device (e.g., an LED lamp) and/or an audible alarm device (e.g., a buzzer), wherein the correspondence between the light and/or sound and the positioning information may be pre-established, and when the positioning information changes during the search process, the brightness of the light or the flashing frequency and/or the sound may be different.
In addition, it should be noted that when both the TWS earphones fall, both the two earphones can determine that they enter a falling state, and respectively send a search signal to the second wireless earphone (the second wireless earphone of the other pair of earphones), and determine positioning information according to the positioning data sent by the second wireless earphone, and send the positioning information to the second wireless earphone for prompting. When the prompt is light, sound and the like, the user can still purposefully perform earphone searching when seeing the light or the flash or the sound prompt, and the searching efficiency is improved.
In summary, according to the TWS dual-wireless headset searching method provided by the present invention, after detecting that the first wireless headset enters a falling state, the first wireless headset sends a searching signal to the second wireless headset, and after receiving the searching signal, the second wireless headset sends positioning data to the first wireless headset, and after receiving the positioning data, the first wireless headset determines positioning information of the first wireless headset relative to the second wireless headset according to the positioning data, and sends the positioning information to the second wireless headset, so that the second wireless headset prompts the positioning information. Therefore, the automatic positioning of the first wireless earphone can be realized through the mode, and a user can search the first wireless earphone through the positioning information prompted by the first wireless earphone, so that the searching difficulty is reduced.
On the basis of the above-described embodiment:
as a preferred embodiment, detecting whether the first wireless headset enters a drop state comprises:
acquiring an acceleration value of a first wireless earphone detected by an acceleration sensor;
and judging whether the acceleration meets a preset falling condition, if so, determining that the first wireless earphone enters a falling state, and otherwise, determining that the first wireless earphone does not enter the falling state.
The embodiment considers that the first wireless earphone has some characteristics different from those of the first wireless earphone in a running state and a walking state during falling, such as acceleration, and when the user runs or walks, the acceleration of the first wireless earphone can be considered to be the same as the running acceleration or the walking acceleration of the user, but when the first wireless earphone falls, the first wireless earphone undergoes a process of free falling after a process of flat throwing or inclined throwing in the air and a process of falling to the ground and bouncing, and the values of the acceleration in the processes are different from those of the running acceleration or the walking acceleration.
Based on this, in the application, the acceleration of the first wireless headset detected by the acceleration sensor is obtained, and whether the acceleration meets the preset falling condition is judged, wherein the preset falling condition can be set based on some characteristics, different from a non-falling state, of the first wireless headset in the falling process. And if the preset falling condition is met, determining that the first wireless earphone enters a falling state, otherwise, determining that the first wireless earphone does not enter the falling state. The embodiment judges the falling state through the acceleration, and the judging process is simple.
The acceleration sensor may be, but is not limited to, a three-axis acceleration sensor or a combination of a three-axis acceleration sensor and a gyroscope, which can achieve the purpose of the present application. In addition, a triaxial acceleration sensor is built in a plurality of existing TWS double-wireless earphones, and the earphones do not need to be additionally arranged, so that the multiplexing of the triaxial acceleration sensor is realized, and the occupation of the space of the TWS double-wireless earphones is reduced.
As a preferred embodiment, the determining whether the acceleration meets a preset drop condition, if so, determining that the first wireless headset enters a drop state, otherwise, determining that the first wireless headset does not enter the drop state includes:
and judging whether a plurality of continuous acceleration values are sequentially reduced and are all larger than respective corresponding falling acceleration threshold values, if so, determining that the first wireless earphone enters a falling state, otherwise, determining that the first wireless earphone does not enter the falling state.
In particular, the above-mentioned embodiments mention that the first wireless headset undergoes a free fall process after an aerial flat or inclined throwing process during a falling process, a falling ground bounce process, the same is true for the maximum acceleration a1 recorded during the first landing and bounce of the first wireless headset, the maximum acceleration a2 … recorded during the second landing and bounce of the first wireless headset, satisfying a1 & gta 2 & gt … & gtaX, X is a value not less than 2, then a1, a2 and aX respectively and correspondingly decrease the acceleration threshold value in sequence, it should be noted that the maximum acceleration of the first wireless earphone when it first lands and then bounces is usually much larger than the normal running acceleration or walking acceleration, then the fall acceleration threshold corresponding to a1, when set, may be set to be greater than normal running or walking acceleration. It can be seen that if the values of the continuous multiple accelerations become smaller in sequence and are all greater than the respective corresponding falling acceleration threshold values, it indicates that the first wireless headset enters the falling state, otherwise, it indicates that the first wireless headset does not enter the falling state. Whether the earphone enters the falling state or not can be simply and accurately determined through the mode.
Of course, other ways to determine whether the headset is in a falling state may be used, and the application is not limited in this respect.
As a preferred embodiment, receiving the positioning data sent by the second wireless headset after receiving the search signal includes:
receiving positioning data which is sent by the second wireless earphone in a cross way after the second wireless earphone receives the searching signal and the packet data passes through the shunt;
determining positioning information of the first wireless headset relative to the second wireless headset from the positioning data, comprising:
and performing beam forming processing on the data which is transmitted in a crossed manner to obtain the positioning information of the second wireless earphone.
Referring to fig. 2 and fig. 3, fig. 2 is a schematic structural diagram of a TWS dual wireless headset searching apparatus provided in the present invention, and fig. 3 is a schematic diagram of a positioning data transmission method provided in the present invention.
In this embodiment, after receiving the search signal, the second wireless headset may output the packetized data (e.g., binary data such as 011, 100, etc.) with the bluetooth working frequency as the frequency, and the second wireless headset may also switch the splitter rapidly to divide the packetized data into two parts to form pseudo beamforming (different from beamforming, beamforming corresponds to two different sets of data, in this application, pseudo beamforming corresponds to two sets of data split from the same data), where two output ends of the splitter are respectively connected to two bluetooth antennas, and the packetized data passing through the splitter is respectively sent out through the two bluetooth antennas. After receiving the two sets of packet data, the first wireless headset performs beamforming on the two sets of packet data to obtain positioning information of the second wireless headset, where the positioning information may include a direction and a distance. It can be seen that the orientation and distance of the first wireless headset relative to the second wireless headset can be accurately obtained in this way.
As a preferred embodiment, the positioning information includes an azimuth and a distance;
prompting the positioning information comprises the following steps:
controlling the brightness of the LED lamp on the second wireless earphone according to the direction and the preset corresponding relation between the brightness of the LED lamp and the direction; and/or the presence of a gas in the gas,
and controlling the flicker frequency of the LED lamp on the second wireless earphone according to the distance and the preset corresponding relation between the flicker frequency of the LED lamp and the distance.
Specifically, the correspondence between the brightness and the orientation of the LED lamp may specifically be: the larger the orientation is, the brighter the brightness of the LED lamp is; the correspondence between the flicker frequency and the distance of the LED lamp may be: the LED lamp may be turned on or off at a higher frequency when the distance is greater, and the LED lamp may be turned on or off at a higher frequency when the distance is greater than the distance. Therefore, the method can facilitate the user to search the fallen earphones, and improves the searching efficiency.
As a preferred embodiment, further comprising:
and judging whether the accelerations with the numerical values larger than the first exit acceleration threshold and smaller than the second exit acceleration threshold are continuously received, and if so, exiting the falling state.
Specifically, after the user searches for the first wireless headset, the first wireless headset is required to exit the falling state, otherwise, the first wireless headset continuously receives the positioning data and calculates the positioning information according to the positioning data. In order to enable the first wireless earphone to exit from a falling state, a key can be additionally arranged for the earphone in advance or existing keys of the earphone can be utilized, a user can send an exit instruction through the key, but considering that the keys are not arranged on a plurality of earphones, if one key is independently arranged, the occupied space of the earphone is increased.
In view of the above technical problems, the user does not need to trigger the first wireless headset to exit from the falling state through an additional button, but the user holds the headset in the palm and swipes the headset rapidly for several times (for example, swipes the headset rapidly for three times) when taking the headset, which is reflected in the acceleration, and the numerical values of the accelerations are both greater than the first exiting acceleration threshold and both smaller than the second exiting acceleration threshold. The user usually has the same acceleration values in multiple shaking motions, but considering that the same person cannot be completely the same in multiple shaking motions, the shaking accelerations of different persons are different (but the difference is not too large), and based on the above, a range is set here, and if the values of the multiple continuous accelerations are all greater than the first exit acceleration threshold and all less than the second exit acceleration threshold, it indicates that the user wants the first wireless headset to exit from the falling state and enter into the normal playing state. Specifically, when the swing is performed three times, the plurality of accelerations here are specifically three accelerations.
Therefore, the earphone can be controlled to exit from the falling state without additionally arranging other devices on the earphone, and the size of the earphone is reduced.
In addition, the exit judgment of the second wireless headset can also be performed in the above manner, and the exit searching state principle of the second wireless headset is the same as the exit falling state principle of the first wireless headset, which is not described herein again. In practical applications, the TWS dual-wireless headset can be held in the same palm at the same time and swiped multiple times quickly.
As a preferred embodiment, receiving the positioning data sent by the second wireless headset after receiving the search signal includes:
receiving positioning data sent by a second wireless earphone in a frequency hopping mode after receiving the searching signal, wherein the frequency hopping period is a preset frequency hopping period;
before the second wireless earphone prompts the positioning information, the method further comprises the following steps:
and the second wireless earphone carries out filtering processing on the positioning information in the preset frequency hopping period and under each frequency, and calculates the average value of the positioning information after filtering processing so as to prompt the average value.
The frequency that the locating data was sent is in the operating frequency range of bluetooth, and the operating band of bluetooth is 2.402GHz to 2.480GHz, if divide into 3 channels with the operating band of bluetooth, is A, B, C three channels respectively, wherein, the A channel corresponds the operating band: 2.402GHz-2.428GHz, the B channel corresponds to the working frequency band: 2.428GHz-2.454GHz, the C channel corresponds to the working frequency band: 2.454GHz-2.480 GHz. The present application considers that if a fixed channel, such as an a channel, is always used for transmitting the positioning data through bluetooth, if another terminal or device in the vicinity of the second wireless headset occupies the channel, the transmission quality of the positioning data may be reduced, and the obtained positioning information may be inaccurate.
Based on this, different from the fixed channel being adopted to transmit the positioning data, in this embodiment, the second wireless headset transmits the packetized data in a frequency hopping manner, for example, the positioning data is transmitted at 2.402GHz in the a channel, and the first wireless headset calculates the positioning information obtained based on the positioning data at 2.402 GHz; the second wireless earphone sends positioning data at 2.428GHz in the B channel, and the first wireless earphone calculates positioning information obtained based on the positioning data at 2.428 GHz; the second wireless earphone sends positioning data at 2.454GHz in the C channel, and the first wireless earphone calculates positioning information obtained based on the positioning data at 2.454GHz, so that a preset frequency hopping period is completed. When receiving the positioning information, the second wireless headset does not directly prompt, but respectively performs filtering processing on three positioning information corresponding to 2.402GHz, 2.428GHz and 2.454GHz in a preset frequency hopping period, theoretically, due to the short frequency hopping and calculation time, the users at the three frequencies can be considered to be at the same position, the three positioning information obtained should theoretically be substantially equal, should not differ significantly, for example, 2.01m for 2.402GHz, 2.02m for 2.428GHz, 3.01m for 2.454GHz, it indicates that the positioning information corresponding to 2.454GHz is inaccurate, and needs to be filtered out, thus, the positioning distance corresponding to 2.01m at 2.402GHz, the positioning distance corresponding to 2.428GHz is 2.02m, the two positioning information are averaged to obtain the positioning distance of 2.015m, and the same is true for the direction.
Therefore, the positioning precision can be obviously improved by the method, the searching difficulty is further reduced, and the searching efficiency is improved.
