Detailed Description
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 illustrating a method for detecting a wearing condition of a wireless headset according to an embodiment of the present invention. The method can comprise the following steps:
step 101: acquiring a first distance value acquired by a distance sensor according to a first preset time interval; wherein, the distance sensor is arranged at the in-ear end of the wireless earphone.
The method for detecting the wearing condition of the wireless headset provided in this embodiment may be a method for detecting whether the wireless headset is worn by a user, that is, the method provided in this embodiment may be implemented when a processor, such as a single chip microcomputer, in the wireless headset executes a corresponding computer program, that is, an execution subject of the method provided in this embodiment may be the processor, such as the single chip microcomputer, in the wireless headset; the method provided by the present embodiment may also be implemented when a terminal, such as a mobile phone, detects whether a wireless headset paired with the terminal is worn by a user, that is, when a processor in the terminal paired with the wireless headset executes a corresponding computer program, that is, an execution subject of the method provided by the present embodiment may be a processor in the terminal paired with the wireless headset.
It should be noted that the distance sensor in this step may be an infrared sensor (ir sensor) as shown in fig. 2, or may also be another distance sensor such as an optical distance sensor, as long as the distance sensor can measure the distance of the relative position (e.g. the pinna of the user) when the user wears the wireless headset, which is not limited in this embodiment. The first distance value in this step may be a distance value collected by the distance sensor at a first preset time interval, and specific content of the first distance value may be set by a designer according to a practical scene and a user requirement, and if the first distance value is set according to a specific type of the distance sensor, if the distance sensor is an infrared sensor, the first distance value may be an infrared value collected by the infrared sensor at the first preset time interval, and if the distance sensor is a wireless headset shown in fig. 3, the greater the infrared value is, the closer the distance between the infrared sensor and the relative position is, and if the infrared value is close to 1023, the contact between the position where the infrared sensor is set in the wireless headset and the relative position (e.g., the auricle of the user) is illustrated. The present embodiment does not limit the first distance value as long as the first distance value can contain information on the distance measured by the distance sensor from the relative position.
Specifically, to the specific setting of the first preset time interval in this step, the setting can be set by the designer, if the distance sensor is an infrared sensor, the infrared sensor can collect infrared numerical values (first distance values) according to a sampling frequency of 50HZ, that is, 50 infrared numerical values can be collected per second, and the first preset time interval is set to 0.02 s. The present embodiment does not set any limit to this.
It can be understood that, through research, the applicant finds that there is a process of adjusting the wearing position of the wireless headset when the user wears the wireless headset, that is, as shown in fig. 3, during the process of adjusting the wearing position of the wireless headset by the user, the distance sensor disposed at the ear entrance end of the wireless headset can detect not only the distance from the pinna of the user (the infrared value is close to 1023), but also the distance from the ear hole of the user (the infrared value is reduced after being close to 1023). Correspondingly, the specific setting position of the distance sensor arranged at the ear-in end of the wireless headset in the step can be set by a designer, if the distance sensor is an infrared sensor, the existing typical infrared sensor setting position shown in fig. 2 can be adopted, the infrared value collected by the infrared sensor is 0 to 1023, and when the infrared value is 1023, the infrared sensor is completely blocked by the relative position. As long as the wearing position of the wireless headset can be adjusted by the user, the distance sensor can detect the distance from the pinna and the ear hole of the user. The present embodiment does not set any limit to this.
Further, the present embodiment may be directed to obtain the number of times of the contact state within a preset time period by comparing a first distance value acquired by the distance sensor at a first preset time interval with a preset contact range, so as to determine the wearing condition of the wireless headset. In order to save the power consumption of the wireless earphone, the method can further comprise the steps of obtaining a second distance value collected by the distance sensor according to a second preset time interval before the step; judging whether the second distance value is within a preset approaching range or not; if yes, the step is entered. That is, whether the method provided by the present embodiment needs to be performed may be determined by determining whether the second distance value is within a preset proximity range, using a setting of a preset proximity range (e.g., infrared values 1000 to 1023) that is larger than a range of a preset contact range (e.g., infrared values 200 to 1023).
Step 102: judging whether a contact state which is more than or equal to a preset number of times exists in a preset time period or not according to the first distance value; if yes, go to step 103.
The contact state is a state that the first distance values of which the number is greater than or equal to the preset number are continuously in the preset contact range, and the preset times are greater than 1.
It is understood that the preset contact range in this step may be a range of the first distance value set by the designer for determining whether the position where the distance sensor is disposed in the wireless headset is in contact with the relative position. The specific setting of the preset contact range may be set by the designer, as shown in fig. 2 and 3, when the infrared value (first distance value) acquired by the infrared sensor (distance sensor) at the first preset time interval is close to 1023 (peak value), the infrared sensor is in contact with the pinna of the user, and the preset contact range may be a range close to 1023 (e.g., 1000 to 1023).
Specifically, when the distance sensor is an infrared sensor, as shown in fig. 2 and 3, the contact state in this step may be a state in which the infrared values greater than or equal to the preset number are continuously close to 1023. Specifically, the specific value setting of the preset number can be set by the designer according to the practical scene and the user requirement, for example, the setting can be 10, that is, if the number of the infrared values approaching 1023 for the first time in fig. 3 reaches 10, two contact states (1023 for the first time and 1023 for the second time) are included in fig. 3. The present embodiment does not set any limit to this.
Correspondingly, as shown in fig. 3, 4 and 5, in the three exemplary processes of wearing the wireless headset by the user, if the infrared value collected by the infrared sensor in fig. 3 and continuously approaching 1023 for the first time can be the position of the infrared sensor contacting with the auricle for the first time when the wireless headset is worn by the user, the infrared sensor detects the distance to the ear cavity when the infrared value is reduced and the position of the wireless headset is adjusted for the user, and the infrared value continuously approaching 1023 for the second time can be the position of the infrared sensor contacting with the auricle for the second time after the wireless headset is adjusted for the user; the difference between fig. 4 and 5 and fig. 3 may be that the infrared sensor position of the wireless headset is first followed by a brief consecutive 1023 (first consecutive 1023) infrared value before it touches the pinna, which first consecutive 1023 may be caused by the infrared sensor position touching the user's face. When the preset number is 10, if the number of the infrared numerical values approaching 1023 for the first time in fig. 4 and 5 does not reach 10 and the number of the infrared numerical values approaching 1023 for the second time in fig. 4 and 5 reaches 10, both the two contact states (1023 for the second time and 1023 for the third time) are included in fig. 4 and 5. That is, the interference of the short contact (e.g., the first continuous access 1023 in fig. 4 and 5) other than the contact state can be excluded by setting the preset number.
It should be noted that, for the specific process of determining whether the contact state greater than or equal to the preset times exists in the preset time period according to the first distance value in this step, the specific process may be set by a designer according to a practical scene and a user requirement, and the first distance value acquired in the preset time period may be directly compared with the preset contact range according to the acquisition sequence to determine whether the contact state greater than or equal to the preset times exists in the preset time period; or according to the collection sequence of the first distance values, each first distance value is compared with a preset contact range in sequence to judge whether a contact state identifier which is more than or equal to a preset number of times is generated in a preset time period, if the contact state identifier is generated, whether the contact state identifier which is more than or equal to the preset times minus 1 is generated again in a first preset time period (such as the time of the preset time period minus the time of the contact state identifier) after the current time is judged, or after the contact state identifier is generated, whether the difference between the current time and the generation time of the regenerated first preset number minus 1 contact state identifier is smaller than a first preset time period or whether the generated preset number minus 1 contact state identifier exists in a first preset time period (such as the time of the preset time period minus the time of the contact state identifier) before the current time after the contact state identifier is generated is judged. The present embodiment does not limit the present invention as long as it can be determined whether or not the contact state greater than or equal to the preset number of times exists within the preset time period.
Correspondingly, the contact state identifier may be an identifier generated in the contact state, and the specific generation process of the contact state identifier may be set by a designer, for example, in the process of sequentially comparing each first distance value with the preset contact range, the contact state identifier may be generated when the first distance value does not belong to the preset contact range and a continuous preset number of first distance values belong to the preset contact range; or when the first distance value belongs to the preset contact range and does not belong to the preset contact range, if the number of the first distance values which previously belong to the preset contact range is greater than or equal to the preset number, generating the contact state identifier. The embodiment does not limit the content, and similarly, the specific content of the contact status identifier may be set by a designer, and the embodiment does not limit the content.
Specifically, the specific value setting of the preset times in this step may be set by a designer, as shown in fig. 3, the value of the preset times may be set to 2, that is, when two contact states exist in the preset time period, it may be determined that the wireless headset is in the wearing state. The present embodiment does not set any limit to this.
Step 103: determining that the wireless headset is in a worn state.
It should be noted that the wearing condition of the wireless headset in this embodiment may include a wearing state and a non-wearing state. The wearing state in this step may be a state in which the user wears the wireless headset.
The method further comprises the following steps of acquiring a third distance value acquired by the distance sensor according to a third preset time interval; judging whether the third distance value is in a preset distance range or not; and if so, determining that the wireless earphone is in a non-wearing state so as to determine whether the user takes off the worn wireless earphone. The preset distance range may be a range outside the preset contact range, where the range is used for determining a distance value collected by the distance sensor when the user does not wear the wireless headset, and if the distance sensor is an infrared sensor, the preset distance range may be an infrared value smaller than 200.
It is understood that the purpose of this step may be to determine that the wireless headset is in a wearing state in a case where there are more than or equal to a preset number of contact states within a preset time period, that is, when it is determined that the user is wearing the wireless headset using the distance sensor. Specifically, as shown in this embodiment, when the wearing condition of the wireless headset is detected only by using the distance sensor, it can be directly determined that the wireless headset is in a wearing state through this step; if the wearing condition of the wireless earphone is detected by using the distance sensor and other sensors, the step can also include a detection process of the wearing condition by other sensors before the step, namely after the situation that the user wears the wireless earphone can be determined by using other sensors, the step is entered to determine that the wireless earphone is in a wearing state. As long as the wireless headset can be determined to be in the wearing state under the condition that the contact state greater than or equal to the preset number of times exists in the preset time period, the embodiment does not limit this.
It can be understood that, with the method provided by the embodiment, for the process that the wireless headset is still on the desktop as shown in fig. 6, since the preset number of times is greater than 1, there is no contact state greater than or equal to the preset number of times within the preset time period, that is, there is only one contact state (continuously close to 1023) in fig. 6, and the wireless headset is not erroneously detected as the wearing state. For the process of placing the wireless earphones in the charging box as shown in fig. 7, since the infrared sensors are not completely blocked after the two wireless earphones are placed in the charging box, the two wireless earphones are close to each other, and the final infrared value is stabilized at about 700. No matter whether 700 belongs to the preset proximity range or not, since there is no contact state greater than or equal to the preset number of times within the preset time period, the wireless headset is not erroneously detected as the wearing state.
In the embodiment of the invention, the wireless earphone is determined to be in the wearing state under the condition that the contact state which is more than or equal to the preset times exists in the preset time period, so that the false recognition condition is reduced, the wearing condition detection accuracy is improved, the user experience is improved, the wearing condition detection which independently utilizes the distance sensor can be more accurate, and the setting cost and the power consumption of the earphone are reduced.
Referring to fig. 8, fig. 8 is a flowchart illustrating another method for detecting a wearing condition of a wireless headset according to an embodiment of the present invention. The method can comprise the following steps:
step 201: and acquiring an infrared numerical value acquired by the infrared sensor according to a second preset time interval.
It is understood that the second predetermined time interval in this step can be set by the designer, for example, the second predetermined time interval can be set to the same value as the first predetermined time interval, for example, 0.02 s; in order to further reduce the power consumption of the wireless headset, the second preset time interval may also be set to a value greater than the first preset time interval, which is not limited in this embodiment.
Step 202: judging whether the infrared numerical value is in a preset approaching range or not; if yes, go to step 203.
The purpose of this step may be to further detect the wearing condition of the wireless headset by sequentially determining whether the infrared values collected at the second preset time interval are within the preset proximity range, and entering step 203 to call a corresponding algorithm program when the infrared values within the preset proximity range exist.
Specifically, the specific range of the preset proximity range in this step may be set by the designer, such as the infrared sensor shown in fig. 2, which acquires an infrared value in a range from 0 to 1023, and if the preset contact range is greater than or equal to 1000(1000 to 1023), the minimum value of the preset proximity range in this step may be set to a value less than 1000, such as 200, that is, the preset proximity range is greater than or equal to 200(200 to 1023).
It can be understood that, in this embodiment, it may be directly determined whether the infrared value is within the preset proximity range through this step, and a manner similar to this step may also be adopted to determine a wearing condition of the wireless headset, that is, whether the user needs to wear the wireless headset, for example, to determine whether the infrared value is within the preset proximity range for multiple times (for example, twice). The present embodiment does not set any limit to this.
Step 203: and acquiring an infrared numerical value acquired by the infrared sensor according to a first preset time interval.
It can be understood that, in this step, the processor acquires the infrared value acquired by the infrared sensor at the first preset time interval by controlling the infrared sensor to acquire the infrared value at the first preset time interval. Specifically, the specific frequency of the infrared value acquired by the infrared sensor at the first preset time interval is acquired by the processor, and the specific frequency can be set by a designer, if the first preset time interval is 0.02s, namely the frequency of the infrared value acquired by the infrared sensor is 50HZ, the infrared value acquired by the infrared sensor can be acquired by the processor once every 0.5s, and 25 infrared values are acquired every 0.5s, so that the wearing condition of the wireless headset is detected by calling an algorithm program through the following steps.
Step 204: according to the acquisition sequence of the infrared numerical values, sequentially comparing each infrared numerical value with a preset contact range, and judging whether a contact state identifier which is more than or equal to a preset number of times is generated in a preset time period; if yes, go to step 205.
Specifically, the step may generate the contact state identifier in the following manner, including:
step 301: judging whether the current infrared value is greater than or equal to a threshold value; wherein the threshold value is the minimum value of a preset contact range; if yes, go to step 302.
The current infrared value in this step may be any one of the infrared values acquired by the infrared sensor in step 203 at the first preset time interval, that is, an infrared value obtained by comparing the current time with the preset contact range. The threshold in this step may correspond to a preset contact range, for example, as shown in fig. 2, the infrared sensor collects an infrared value in a range from 0 to 1023, and if the preset contact range is from 1000 to 1023, the threshold in this step may be 1000, which is not limited in this embodiment.
Specifically, for the case where the current infrared value is less than the threshold, the next infrared value may continue to be compared with the contact range.
Step 302: judging whether n infrared values before the current infrared value are all larger than or equal to a threshold value, and the n +1 infrared value before the current infrared value is smaller than the threshold value; if yes, go to step 302.
It is understood that n in this step may be a preset number minus 1. That is, if all the n infrared values before the current infrared value are greater than or equal to the threshold, it indicates that the state where the current infrared value is located has the preset number of infrared values continuously located in the preset contact range, and whether the next infrared value is greater than or equal to the threshold, the state where the current infrared value is located can be determined as the contact state; if the (n + 1) th infrared value before the current infrared value is smaller than the threshold, the contact state where the current infrared value is located is a new contact state, and is not a previous continuous contact state (that is, the contact state corresponding to the contact state identifier is generated).
In the case where the determination condition in this step is not satisfied, the next infrared value may be continuously compared with the contact range.
Step 303: and generating a contact state identifier.
It can be understood that, for the specific process of determining whether the contact state identifier greater than or equal to the preset number of times is generated within the preset time period by using the generated contact state identifier in step 204, the specific process may be set by a designer according to a practical scene and a user requirement, and if the timing is started after step 203 is entered, the specific process may be determined whether the contact state identifier greater than or equal to the preset number of times is generated within the preset time period; after the contact state identifier is generated, whether the contact state identifier which is greater than or equal to the preset number minus 1 is generated again in a first preset time period (such as the time of the preset time period minus the time of the contact state identifier) after the current time is judged; after the contact state identifier is generated, whether the difference between the current time and the generation time of the regenerated first preset times minus 1 contact state identifier is smaller than a first preset time period or not is judged; or after the contact state identifier is generated, whether the contact state identifier generated by subtracting 1 from the preset number exists in a first preset time period (for example, the time of the preset time period minus the time of the contact state identifier) before the current time is judged. The embodiment does not limit the generation of the contact state identifier greater than or equal to the preset number of times within the preset time period as long as it can be determined.
Correspondingly, the specific value setting of the preset time period in step 204 may be set by an actual person, which is not limited in this embodiment.
Specifically, for a case that the contact state identifier greater than or equal to the preset number of times is not generated within the preset time period, the current wearing condition of the wireless headset can be maintained.
Step 205: determining that the wireless headset is in a worn state.
It can be understood that, in order to further ensure the detection accuracy of the wearing condition of the wireless headset, before this step, it may further include determining whether the collected infrared value is continuously within the preset contact range within a second preset time period, that is, under the condition that the contact state identifier greater than or equal to the preset number of times is generated within the preset time period, further determining whether the user wears the wireless headset.
Step 206: and acquiring an infrared numerical value acquired by the infrared sensor according to a third preset time interval.
It should be noted that the third preset time interval in this step may be set by the designer, for example, the third preset time interval may be set to the same value as the first preset time interval, for example, 0.02 s; in order to further reduce the power consumption of the wireless headset, the third preset time interval may also be set to a value greater than the first preset time interval, which is not limited in this embodiment.
It can be understood that, in order to improve the detection speed of the wearing condition of the wireless headset, when the step 204 determines that the contact state identifier generated within the preset time period is greater than or equal to the preset number of times while the wireless headset is in the wearing state, the user may not complete the adjustment of wearing the wireless headset, and therefore, this step may be performed after a certain time period after the step 205, so as to avoid the influence on the wearing condition detection when the adjustment process of wearing the wireless headset by the user is long.
Step 207: judging whether the infrared numerical value is in a preset far range or not; if yes, go to step 208.
The purpose of this step may be to determine whether the infrared values collected at the third preset time interval are within the preset distance range by sequentially judging whether the infrared values collected at the third preset time interval are within the preset distance range under the condition that the wireless headset is determined to be in the wearing state, and if the infrared values within the preset distance range exist, step 208 is performed to determine that the wireless headset is in the non-wearing state, that is, the user takes off the worn wireless headset.
Specifically, the specific range of the preset distance range in this step may be set by the designer, for example, the infrared sensor shown in fig. 2, acquires an infrared value in a range from 0 to 1023, and if the preset contact range is greater than or equal to 1000(1000 to 1023), the maximum value of the preset distance range in this step may be set to a value less than 1000, for example, 700, that is, the preset distance range is less than or equal to 700(0 to 700).
It can be understood that, in this embodiment, it may be directly determined whether the infrared value is within the preset distance range through this step, and a manner similar to this step may also be adopted to determine the wearing condition of the wireless headset, that is, whether the user has taken off the worn wireless headset, for example, to determine whether the infrared value is within the preset distance range for multiple times (for example, twice). The present embodiment does not set any limit to this.
Step 208: determining that the wireless headset is in a non-worn state.
The non-wearing state in this step may be a state in which the user does not wear the wireless headset.
In the embodiment, whether the infrared value is in the preset proximity range or not is judged, and whether the user needs to wear the wireless earphone or not is determined, so that the wearing condition of the wireless earphone is not detected by calling an algorithm program when the user does not need to wear the wireless earphone, and the power consumption of the wireless earphone is reduced; whether the infrared numerical value is within the preset distance range or not is judged, whether the worn wireless earphone is taken down by the user or not is determined, the wearing state of the wireless earphone can be automatically adjusted to be a non-wearing state, and user experience is further improved.
