In the above description, the skilled person can design the instructions according to the solutions provided in the present disclosure. How the instructions control the operation of the processor is well known in the art and will not be described in detail herein.
< method examples >
The present embodiment provides a loss detection method for a Wireless headset, which may be performed by, for example, the Wireless headset 1000 shown in fig. 1, and in one example, the Wireless headset 1000 may be, for example, a True Wireless Stereo (TWS) bluetooth headset, which includes a first headset and a second headset, each of which is provided with a pressure sensor and an infrared sensor.
The TWS headset may implement detection of wearing and taking off of a user by one or more of a capacitive sensor (Cap-sensor), an infrared sensor (IR-sensor), and an acceleration sensor (G-sensor). In the embodiment, on the basis of the wearing detection of the TWS headset, the pressure value in the taking-off action is acquired by the pressure sensor, and whether the headset is normally taken off or accidentally falls off is judged.
The working principle of the pressure sensor is that when the earphone is touched or pressed to cause deformation, the pressure sensor in the earphone can detect corresponding pressure value change. The user can cause the deformation of the contact part when the user normally takes off the pressure sensor, so that a corresponding pressure value is generated, and the contact part cannot generate obvious pressure value change when the user accidentally drops off the pressure sensor. Therefore, according to different shapes of the earphone, the pressure sensor is arranged at a part which is usually contacted and pressed when the user takes off the earphone, and is used for detecting the pressure value change when the earphone is taken off, thereby judging whether the earphone is taken off manually.
Specifically, as shown in fig. 2, the method includes the following steps 2100 to 2200:
in step 2100, when the wireless headset is in a wearing state, if it is detected that the intensity of the infrared signal of the first headset is smaller than a first threshold value, calculating whether a current pressure value is smaller than a second threshold value.
In this step, if it is detected that the intensity of the infrared signal of the first earphone is smaller than a first threshold, it indicates that the current state of the first earphone is far away from the ear of the user, and at this time, it may be determined whether the first earphone is normally taken off or accidentally dropped by the user according to a comparison result of a current pressure value obtained by a pressure sensor and a second threshold; and the second threshold is a pressure threshold for normally taking off the earphone.
Because the earphone can have the user to hold the process of taking off the earphone with the hand when normally taking off, this can lead to the part that the user held to take place the deformation thus produce the pressure value change, and do not have this pressure change when the earphone drops unexpectedly, consequently, in this embodiment, when detecting the current state of first earphone for keeping away from user's ear, further calculate whether current pressure value is less than the second threshold value.
Specifically, when the calculated current pressure value is smaller than the second threshold, the average value of all pressure sensor data in a preset pressure sensor data interval may be calculated as the current pressure value; and comparing the current pressure value with the second threshold value to obtain a comparison result of whether the current pressure value is smaller than the second threshold value.
Step 2200, if the current pressure value is smaller than the second threshold, sending a loss detection trigger message to the second earphone; and if the connection is lost in the detection result, the prestored earphone loss prompt tone is played.
Specifically, after the second earphone receives the loss detection trigger message, the first earphone and the second earphone are not disconnected, the second earphone plays a prestored earphone falling prompt tone according to the loss detection trigger message, and the user is prompted that the first earphone falls off from the ear at the moment in the first time. The strength of the earphone drop prompt tone is low.
Further, the second earphone also detects the connection state with the first earphone; if the detection result is that the connection is lost, the communication connection between the first earphone and the second earphone is disconnected, the first earphone is in a lost state, and at the moment, the second earphone plays a prestored loss prompting sound for ears. The intensity of the loss of the pair of ears alert tone may be set higher, for example, to alert tone plus repeated tone.
It can be understood that, if the comparison result indicates that the current pressure value is not less than the second threshold value, which indicates that the first earphone is normally taken off by the user, the second threshold value may be updated according to the current pressure value. In one example, the pressure value offset may be calculated between the current pressure value and the last pressure value; and then updating the normal picking history average pressure value according to the pressure value offset.
Specifically, when the historical average pressure value of the normal picking is updated, the current pressure value and the historical average pressure value of the normal picking may be compared. If the current pressure value is smaller than the normal picking history average pressure value, according to a formula
Figure BDA0002713433940000071
Updating the historical average pressure value of the normal take-off; if the current pressure value is larger than the normal picking history average pressure value, according to a formula
Figure BDA0002713433940000072
And updating the normal picking history average pressure value.
Wherein, FfRepresenting said current pressure value, Ff is allRepresenting the normal picking history average pressure value; alpha is the updated historical average pressure value of the normal picking; Δ α is the historical average offset of the pressure values.
In another application scenario, if it is detected that the intensity of the infrared signal of the second earphone is smaller than a first threshold, when the current pressure value calculated is smaller than a second threshold, the second earphone also sends a loss detection trigger message to the first earphone, so that the first earphone determines whether the second earphone is lost according to the earphone connection state.
Specifically, in this scenario, the first headset may receive a loss detection trigger message from the second headset; playing a prestored earphone falling-off prompt tone according to the loss detection trigger message; detecting the connection state of the second earphone; and if the detection result is that the connection is lost, playing the loss of the opposite ears prompt tone.
< example >
In this example, the wireless headset is normally powered on, the infrared sensor (IR sensor) and the pressure sensor are turned on, and the initial wearing state of the headset is recorded as unworn. The method includes the steps of firstly collecting an original pressure value of a pressure sensor, forming N (for example, N is 10) data by using a data value at the current moment and N is 1, recording the data value as a preset pressure sensor data interval, and caching the preset pressure sensor data interval in a memory area (in the whole judgment process, the data area is continuously updated).
Then judging the detection state of the IR sensor, if the IR sensor is close to the IR sensor, calculating the average value of all pressure sensor data in a preset pressure sensor data interval as the current pressure value
Figure BDA0002713433940000081
Comparison FnWith a second threshold value F, if FnIf the current value is more than f, the earphone is judged to be normally worn, and the state of the earphone at the moment is recorded as worn. On the contrary, if the operation of collecting the original pressure value of the pressure sensor is far away from the repeated operation, the operation is repeated. It should be noted that the detection of approach or departure by the IR sensor is a prior art, and will not be described in detail here.
When the state of the earphone is a wearing state, the following steps are executed:
step 3100, when the IR sensor of the first earphone detects that the earphone status is far away, calculating a current pressure value of a preset pressure sensor data interval
Figure BDA0002713433940000082
Comparison FnFrom the normal plucking threshold α, if FnIf so, determining that the first earphone is normally taken off, and executing step 3300, otherwise, determining that the first earphone accidentally falls off, and executing step 3200.
At this time, the state of the earphone at this time needs to be recorded as not worn.
The judging method comprises the following steps: recording the pressure value of the ith picking as FiThe pressure value of the i +1 th picking is Fi+1The offset of the two pressure values is Δ αi＝|Fi+1-FiL, average offset of

Then calculating the average value of the history of M times of normal picking

If Ff＞Ff is allIf so, the fine adjustment alpha value is alpha + delta alpha, and the history average pressure value F which is normally picked off is updatedf is allIs composed of
Figure BDA0002713433940000086
Step 3200, if it is determined that the first earphone is accidentally dropped, trigger a loss detection mechanism and send a loss detection message to the second earphone. And if the second earphone receives the loss detection message, triggering an earphone falling prompt tone, modifying the opposite-ear state into accidental falling, and judging whether the earphone is lost or not according to the opposite-ear connection state. If the connection state of the opposite ears is detected to be lost and the opposite ears are accidentally dropped, the opposite ears are judged to be lost, and an opposite ears loss prompt tone is played. Otherwise, the earphone is normally taken off and is not lost, and the state of the earphone is not changed.
In step 3300, if it is determined that the pickup is normally taken off, the normal pressure value F at the determination time is determinedfThe pressure values are recorded in the memory and form a data interval with the normal pressure values which are recorded before. The data interval has a size of n, namely, the data interval consists of the normal pressure value at the judgment moment and the previous n-1 recorded normal pressure values. If the size of the data interval is less than n, n is the real size of the data interval.
The above description is a complete donning and doffing process. In the whole judging process, whether the current state of the earphone is worn or not is judged, whether the state of the earphone at the previous time is unworn or not needs to be checked, wearing detection is carried out if the earphone is unworn, and otherwise, taking off judgment is carried out.
The method for detecting loss of a wireless headset according to the present embodiment has been described above with reference to the accompanying drawings and specific examples. By arranging an infrared sensor and a pressure sensor in a wireless earphone, when the wireless earphone is in a wearing state, if the intensity of an infrared signal of the first earphone is detected to be smaller than a first threshold value, whether a current pressure value is smaller than a second threshold value is calculated; if the current pressure value is smaller than the second threshold value, sending a loss detection trigger message to the second earphone; and if the connection is lost in the detection result, the prestored earphone loss prompt tone is played. Therefore, whether the earphone is normally taken off or accidentally drops can be judged through the current pressure value, and the user is prompted through the prompt tone when the earphone accidentally drops, so that the earphone is prevented from being lost due to accidental dropping.
