< example >
< method >
In the present embodiment, a wearing detection method of an earphone is provided. The method may be performed by a headset. The headset may be any headset having a processor and memory. In one example, the headset may be the headset 1000 shown in fig. 1.
Fig. 2 is a flowchart of an example of a wearing detection method of an earphone according to an embodiment of the present invention.
As shown in fig. 2, the wear detection method may include the following steps S2100 to S2300.
In step S2100, it is detected whether a first event occurs in which the earphone approaches the ear of the user.
In one embodiment of the invention, the first event that the headset approaches the user's headset may be: detecting that the distance between the earphone and the ear of the user is smaller than or equal to a preset distance threshold value through a proximity sensor arranged on the earphone; or the light intensity detected by a proximity sensor arranged on the earphone is less than or equal to a preset light intensity threshold value.
Specifically, the distance threshold may be preset in accordance with an application scenario, experimental data, experience, or the like, and stored in the proximity sensor. The light intensity threshold may be preset according to an application scenario, experimental data, experience, or the like, and stored in the proximity sensor.
The proximity sensor of the present embodiment may be an electro-optical proximity sensor. The common proximity sensor supports the interrupt triggering mode and has small power consumption.
In one example, the proximity sensor may be disposed inside the earphone, and the casing of the earphone may be provided with a sensing window. When the user holds the earphone close to the ear, the sensing window is shielded, so that the distance detected by the proximity sensor can be smaller than or equal to a preset distance threshold value, or the light intensity detected by the proximity sensor is smaller than or equal to a preset light intensity threshold value.
If the distance detected by the proximity sensor can be smaller than or equal to a preset distance threshold value, or the detected light intensity is smaller than or equal to a preset light intensity threshold value, the proximity sensor can trigger interruption, and report interruption information to the earphone. Then, the earphone may determine that the first event that the earphone approaches the ear of the user occurs in case of receiving the interrupt information reported by the proximity sensor.
If the proximity sensor detects a distance greater than a distance threshold or a light intensity greater than a light intensity threshold, the proximity sensor does not trigger an interrupt, and it can be determined that the first event of the headset approaching the user's ear has not occurred.
In another embodiment of the invention, a contact switch may be provided on the headset. When the earphone is placed horizontally or in a matched earphone box, the contact switch is in a pressed state. When the headset is picked up, the contact switch is in a raised state. Thus, the first event that the headset approaches the user's ear may also be that the contact switch is in a raised state. Then, it may be that in the case where the contact switch provided on the headphone is in a pressed state, it is determined that the first event has not occurred; in the case where the contact switch is in the lifted state, it is determined that the first event occurs.
In yet another embodiment of the present invention, electrode contacts may be provided on the headset and in the matching headset case for use therewith. When the earphone is placed in the earphone box, the earphone detects that the electrode contact of the earphone is provided with a voltage higher than a preset voltage threshold value. When the earphone is taken out of the earphone box, the earphone detects that the electrode contact voltage of the earphone is reduced to be lower than or equal to the voltage threshold value. Thus, the first event that the headset is close to the user's ear may also be that the electrode contact voltage provided on the headset is below or equal to the voltage threshold. Then, it may be determined that the first event does not occur in a case where it is detected that the voltage of the electrode contact provided on the earphone is higher than the voltage threshold; in the case where it is detected that the voltage of the electrode contact is lower than or equal to the voltage threshold, it is determined that the first event occurs.
In step S2200, in the case that the occurrence of the first event is detected, controlling an acceleration sensor provided on the headset to collect acceleration data.
Specifically, the acceleration sensor provided on the headphone may be a three-axis acceleration sensor. The acceleration data collected by the triaxial acceleration sensor may include acceleration components corresponding to three coordinate axes.
And step S2300, detecting whether the earphone is worn or not according to the acceleration data.
In the embodiment of the invention, the power consumption of the acceleration sensor for acquiring the acceleration data in real time is considered to be larger, and the battery power of the wireless earphone is limited, so that the step of acquiring the acceleration data by the acceleration sensor is triggered by detecting whether a first event that the earphone approaches to the ear of a user occurs, namely, the acceleration sensor is controlled to acquire the acceleration data under the condition that the first event occurs, and whether the earphone is worn or not is detected according to the acceleration data. Therefore, only under the condition that the earphone is close to the ear of the user, the acceleration sensor is started to collect acceleration data, and then the earphone wearing detection is executed according to the collected acceleration data, so that the power consumption of the earphone can be reduced.
In one embodiment, the step of detecting whether the headset is worn according to the acceleration data may further include steps S2310-S2330 as shown in fig. 3:
in step S2310, the direction of the gravitational acceleration in the coordinate system of the preset acceleration sensor is determined according to the acceleration data.
The three coordinate axes of the triaxial acceleration sensor may constitute a coordinate system of the acceleration sensor. When the posture of the earphone is changed, the posture of an acceleration sensor arranged on the earphone is also changed, so that the coordinate system of the acceleration sensor is changed. Specifically, the directions of the three coordinate axes may be changed.
However, in the usual case, the gravitational acceleration is fixed. Therefore, the direction of the gravitational acceleration in the coordinate system changes as the pose of the headset changes.
Since the magnitude of the gravitational acceleration is fixed, the direction of the gravitational acceleration in the coordinate system can be determined according to the magnitude of the gravitational acceleration and the acceleration data.
Step S2320, an included angle between the direction of the gravity acceleration in the coordinate system and a set coordinate axis in the coordinate system is determined.
The setting coordinate axis in this embodiment may be determined in advance according to the installation manner of the acceleration sensor in the earphone. The set coordinate axis may be one or more coordinate axes of the coordinate system. In the case where the set coordinate axis is a plurality of coordinate axes, an angle between the direction of the gravitational acceleration in the coordinate system and the set coordinate axis may be an angle between the direction of the gravitational acceleration in the coordinate system and each set coordinate axis.
Step S2330, whether the earphone is worn or not is detected according to the included angle.
Specifically, the earphone may be determined to be in a wearing state under the condition that the included angle is within a preset included angle range. And under the condition that the included angle is out of the range of the included angle, judging that the earphone is not worn.
The included angle range may be preset according to an application scenario or experimental data.
And whether the earphone rotates or not can be detected according to the change condition of an included angle between the direction of the gravity acceleration in the coordinate system and a set coordinate axis in the coordinate system, and whether the earphone is worn or not can be judged according to the detection result.
Specifically, the earphone is determined to rotate when the variation of the included angle is detected to be greater than or equal to a preset angle threshold value, and then the earphone can be determined to be in a wearing state. Under the condition that the detected included angle variation is smaller than the preset angle threshold value, the earphone can be judged not to rotate, and then the earphone can be judged to be in an unworn state.
The angle threshold may be preset according to an application scenario or experimental data.
Thus, it is possible to determine whether or not the earphone is worn, based on the acceleration data.
In one example, the acceleration data collected by the acceleration sensor is a sampled value. Then, before performing step S2300, the wear detection method may further include:
and converting the sampling value into an acceleration value with a set format according to a preset sampling interval and a sampling bit width, and carrying out wearing detection on the earphone.
Specifically, there may be a linear relationship between the sampled value and the acceleration value. The sampling interval and the sampling bit width are determined by the acceleration sensor itself. The sampling interval may be, for example, -2g to 2 g. Wherein g is a gravitational constant. The sampling bit width may be, for example, 14-16 bits. In the case where the sampling bit width is 16 bits, the size of the sampling value may be 0 or more and 2 or less16-1. Then, an acceleration value of-2 g for a sample value of 0 and a sample value of 216The acceleration value for-1 is 2 g. Therefore, a formula reflecting the linear relation between the sampling value and the acceleration value can be obtained according to the sampling interval and the bit width as follows:
wherein y/g is an acceleration value, g is a gravity constant, and x is a sampling value.
Therefore, whether the earphone is worn or not can be conveniently detected by converting the sampling value into the acceleration value with the set format.
In one embodiment, the wear detection method may further include steps S4100-S4300 as shown in fig. 4:
step S4100, controlling the acceleration sensor to cache the acquired acceleration data in its fifo register.
The acceleration sensor of the present embodiment may be provided with a first-in first-out register. The acceleration sensor can set the working mode of the acceleration sensor through the communication interface. When the acceleration sensor is set to be in a FIFO (First in First out) working mode, the acquired acceleration data can be cached into an internal FIFO register according to the working frequency at that time.
In step S4200, it is detected whether a second event for reading the acceleration data buffered in the fifo register occurs.
In one example, the second event may include any one or more of:
the queue depth of the acceleration data cached in the first-in first-out register reaches a preset depth threshold value;
overflowing the acceleration data cached in the first-in first-out register;
a preset read cycle is reached.
And under the condition that the second event comprises that the queue depth of the acceleration data cached in the first-in first-out register reaches a preset depth threshold, if the queue depth of the acceleration data cached in the first-in first-out register reaches the preset depth threshold, judging that the second event occurs. And if the queue depth of the acceleration data cached in the first-in first-out register does not reach a preset depth threshold value, judging that the second event does not occur, and continuing to cache the acceleration data.
Further, the depth threshold may be set according to a minimum number of acceleration data required for detecting whether the headset is worn and a maximum value of a queue depth for buffering the acceleration data in the first-in first-out register.
On this basis, the depth threshold may be close to or in a multiple relation with a minimum amount of acceleration data required for detecting whether the headset is worn. For example, in the case where the minimum number of acceleration data required for detecting whether or not the headphone is worn is 80 sets of acceleration data, if the maximum value of the queue depth for buffering the acceleration data in the first-in first-out register is greater than or equal to 80 sets, the depth threshold may be set to 80. In this way, the step of detecting whether the headset is worn can be performed once each time the occurrence of the second event is detected. In the case where the minimum number of acceleration data required for detecting whether the headset is worn is 80 sets of acceleration data, if the maximum value of the queue depth for buffering the acceleration data in the fifo register is less than 80 sets, for example, only 64 sets, the depth threshold may be set to 40. Thus, each time a second event is detected to occur, the acceleration data buffered in the FIFO register is read once. The step of detecting whether the headset is worn or not is performed every two reading cycles.
In the case that the second event includes that the acceleration data buffered in the fifo register overflows, the fifo register may overflow when the queue depth of the buffered acceleration data reaches a preset depth threshold. Then, in the event of an overflow of the first-in first-out register, it may be determined that the second event occurred. In the case where the FIFO register does not overflow, it may be determined that the second event has not occurred.
In the case where the second event includes reaching a preset read period, the read period may be set in advance according to a sampling period of the single acceleration data and a depth threshold of the fifo register. The read period may be a sampling period equal to a single acceleration data multiplied by a depth threshold. The sampling period of the single acceleration data may be determined according to the depth threshold and the operating frequency of the acceleration sensor. Specifically, the sampling period of the single acceleration data is equal to the depth threshold divided by the operating frequency of the acceleration sensor. The operating frequency of the acceleration sensor may be determined by the acceleration sensor itself.
Step S4300, when the second event is detected, reading the acceleration data buffered in the fifo register for wearing detection.
When step S4300 is completed, step S2300 described above is executed to detect whether or not the headphone is worn based on the read acceleration data.
Therefore, the acceleration data collected by the acceleration sensor are buffered in an internal first-in first-out register in batches, and the time for reading the acceleration data is shorter than that for reading the acceleration data once. And under the condition that a second event for reading the acceleration data cached in the first-in first-out register is detected to occur, reading the acceleration data cached in the first-in first-out register to carry out earphone wearing detection, packet loss cannot be generated, and the detection result of earphone wearing is more accurate.
In one example, if the queue depth of the acceleration data buffered in the fifo register is greater than or equal to the minimum number of acceleration data required for detecting whether the headset is worn, the detection result that the headset is in a worn state or a non-worn state may be obtained according to the acceleration data read in one reading cycle. If the queue depth of the acceleration data cached in the first-in first-out register is smaller than the minimum number of the acceleration data required for detecting whether the earphone is worn, the acceleration data read in the next reading period needs to be waited, and the wearing state of the earphone is detected according to the acceleration data read in the plurality of reading periods.
Therefore, according to the acceleration data read in one reading period, the obtained earphone wearing detection result can be in a wearing state, a non-wearing state or an insufficient data state, and cannot be judged. And under the condition that the detection result is that the data is insufficient and cannot be judged, the acceleration sensor is required to continuously acquire acceleration data for detection. And under the condition that the detection result that the earphone is in the wearing state or the non-wearing state is obtained according to the acceleration data detection, the acceleration sensor can be controlled to stop collecting the acceleration data. In this way, the power consumption of the headset can be further reduced.
