Description

TECHNICAL FIELD

[0002] Currently, earphone charging boxes are generally used to provide charging functions for wireless Bluetooth earphones and wireless sports earphones. The earphone charging box can also be provided with a screen, a sensor and other modules to provide more interactive functions. For example, the screen on the earphone charging box can display earphone power, earphone charging box power, time and other information to help the user understand the current state of the earphone. The sensor in the earphone charging box can detect specific operations of the user on the earphone charging box to achieve specific functions. For example, when the user clicks or double-clicks the earphone charging box, the screen on the earphone charging box can be turned on to help the user understand the earphone power information. For another example, when the user clicks or double-clicks the earphone charging box, the hatch of the earphone charging box can be popped open to facilitate the user to take out the earphone. Screen wake-up refers to the process in which the earphone box controls the screen to visually turn off and on after the screen is turned off.

However, it will be apparent to those skilled in the art that the present application can be practiced in other embodiments that depart from these specific details.

[0050] In addition, in the description of the present application and the appended claims, the terms "first", "second", "third", etc. are used only to distinguish descriptions, and cannot be understood as indicating or implying relative importance.

[0051] In the present application, the reference to "one embodiment" or "some embodiments" means that the specific features, structures or characteristics described in connection with the embodiment are included in one or more embodiments of the present application. Therefore, the statements "in one embodiment", "in some embodiments", "in other some embodiments", "in further some embodiments" and the like appearing in different places in the specification are not necessarily all referring to the same embodiment, but mean "one or more but not all embodiments", unless otherwise specifically emphasized. The terms "include", "contain", "have" and their variants mean "include but not limited to", unless otherwise specifically emphasized.

[0052] Figure 1 is a flowchart of a method for controlling an earphone case based on an occlusion state according to an embodiment of the present application.

[0053] S11, multiple separate occlusion detections are performed on whether there is an occlusion near the earphone case at multiple times, to obtain multiple separate occlusion states corresponding to the multiple times respectively, wherein one separate occlusion detection at one time obtains one separate occlusion state, and the multiple separate occlusion states constitute an occlusion state change sequence embodying occlusion state changes.

[0054] The earphone case refers to a device for accommodating earphones. Some earphone cases are configured with a charging interface, so that the earphones in the earphone case can be charged. Therefore, the earphone case with a charging function can also be called an earphone charging case. The earphones include but are not limited to Bluetooth earphones, wireless earphones, wireless Bluetooth earphones, open Bluetooth earphones, sports earphones, running earphones, running dedicated earphones, hanging earphones, hanging Bluetooth earphones, non-ear-in earphones, high-end earphones, AI earphones, smart earphones, AI smart earphones, Dolby earphones, Dolby earphones, Dolby Bluetooth earphones, Dolby Atmos earphones, etc.

[0055] In this way, whether there is an occlusion near the earphone box can be detected separately by setting a sensor. The sensor includes but is not limited to an infrared sensor, a laser sensor, an ultrasonic sensor, a millimeter wave radar sensor, an optical sensor, etc. For example, the infrared sensor, the laser sensor, the ultrasonic sensor, and the millimeter wave radar sensor can detect whether there is an occlusion near the earphone box by emitting and receiving corresponding light signals. If the time difference between the received light signal and the emitted light signal is less than a predetermined time, it means that the occlusion is very close, and it can be determined that the separate occlusion state of the earphone box is "there is an occlusion near". Conversely, if the time difference between the received light signal and the emitted light signal is greater than a predetermined time, or no light signal is reflected back by the receiving end, it means that the occlusion is far away, and it can be determined that the separate occlusion state of the earphone box is "there is no occlusion near". For another example, the optical sensor can detect whether there is an occlusion near the earphone box by obtaining an image near the earphone box. The above-mentioned sensors can be independently arranged in the earphone box, or can be integrated with the screen in the earphone box to be arranged in the earphone box.

[0056] The embodiment of the present application proposes that the earphone box can be detected multiple times at multiple times whether there is an occlusion near the earphone box, thereby obtaining multiple separate detection states corresponding to the earphone box at multiple times respectively. One separate occlusion detection at one time obtains one separate occlusion state. For example, in combination with the above-mentioned Figure 2 , Figure 2 The process of detecting multiple times at multiple times whether there is an occlusion near the earphone box is shown. The first separate occlusion detection is performed at 14:43:01 whether there is an occlusion near the earphone box, and the first separate occlusion state of the earphone box at this time is "there is an occlusion". The second separate occlusion detection is performed at 14:43:06 whether there is an occlusion near the earphone box, and the second separate occlusion state of the earphone box at this time is "there is no occlusion". The third separate occlusion detection is performed at 14:43:11 whether there is an occlusion near the earphone box, and the third separate occlusion state of the earphone box at this time is "there is an occlusion". The above-mentioned multiple separate occlusion states constitute an occlusion state change sequence embodying the change of the occlusion state, and in the previous example, the occlusion state change sequence constituted by the three separate occlusion states is "there is an occlusion, there is no occlusion, there is an occlusion", and the occlusion state change sequence embodies the change of the occlusion state near the earphone box.

[0057] S12, when the occlusion state change sequence meets a predetermined state sequence corresponding to a predetermined operation, controlling the earphone box to perform the predetermined operation.

[0058] In this case, the correspondence between the predetermined operation and the predetermined state sequence can be pre-set. For example, the predetermined state sequence 1 is "with an obstacle, without an obstacle, with an obstacle", and the predetermined operation 1 corresponding to the predetermined state sequence 1 is to light up the screen on the earphone box to wake up, so as to facilitate the user to understand the information related to the earphone, such as the earphone power and the like. For another example, the predetermined state sequence 2 is "with an obstacle, with an obstacle, with an obstacle, without an obstacle", and the predetermined operation 2 corresponding to the predetermined state sequence 2 is to pop up the hatch of the earphone box, so as to facilitate the user to take out the earphone.

[0059] When the obtained obstacle state change sequence in S11 matches the predetermined state sequence corresponding to a predetermined operation, the earphone box can be controlled to perform the predetermined operation. In the previous example, the obstacle state change sequence composed of three individual obstacle states is "with an obstacle, without an obstacle, with an obstacle", which matches the predetermined state sequence 1, and thus the earphone box can be controlled to perform the predetermined operation 1, i.e. to light up the screen to wake up.

[0060] In the prior art, since the screen size of the earphone charging box is small, the user usually puts the earphone charging box into the pocket when carrying it. The screen is easily misrecognized as a single click or double click operation during contact with the clothes pocket, causing the earphone charging box screen to wake up abnormally, and even further affecting the misoperation of the earphone charging box function. The embodiments of the present application pre-set the predetermined state sequence corresponding to the predetermined operation, so that the predetermined operation corresponding to the predetermined state sequence is only performed when the obstacle state change sequence composed of multiple individual obstacle states obtained by multiple single obstacle detections at multiple times matches the predetermined state sequence, thereby providing a technical solution for contactless execution of the predetermined operation, which can avoid the technical problems of the prior art that the user's simple single click and double click operation to control the earphone box is prone to misoperation and misrecognition, avoid unnecessary power consumption caused by misoperation of the earphone box, save energy, solve the disturbance caused by abnormal functions of the earphone caused by misrecognition, and thus improve the user's experience of using the earphone.

[0061] In one embodiment, the individual obstacle detection includes the following S211, S22, S23.

[0062] S211, control the infrared emission end in the earphone box to emit a plurality of infrared light beams.

[0063] The infrared sensor can include an infrared emission end, an infrared distance measuring module, etc.

[0064] The infrared emission end refers to an electronic device that converts electrical signals into specific wavelength infrared light beams and performs directional radiation, and its core function is to provide an optical signal source for an infrared communication, remote control or sensing system.

[0065] In the process of emitting multiple infrared light beams, the infrared emission end can continuously emit multiple infrared light beams in a time period, or can emit one light beam every interval. Both of the above-mentioned manners belong to the protection scope of the present application.

[0066] S22, determining the shielding state of each of the multiple infrared light beams according to the size relationship between the actual shielding distance measured by the infrared ranging module in the earphone box based on the multiple infrared light beams respectively and the first effective shielding distance threshold.

[0067] The infrared ranging refers to the principle that the infrared light beam is not diffused when propagating. The infrared light beam is emitted from the infrared emission end, reflected by the reflecting object, received by the infrared sensor, and then the actual shielding distance can be calculated according to the time from emission to reception and the propagation speed of the infrared light beam.

[0068] If an object is encountered, the multiple infrared light beams will be reflected back and received by the infrared sensor in the earphone box. When the multiple infrared light beams are received, the actual shielding distance of the object near the earphone box can be determined according to the difference between the reception time and the emission time and the speed of the infrared light beam. For example, the actual shielding distance can be determined based on the following calculation formula (1).

[0069] Actual shielding distance = (reception time - emission time) * speed of infrared light beam (1)

[0070] The speed of the infrared light beam can be the speed of light or other speed values.

[0071] If the actual shielding distance of the infrared light beam is less than the first effective shielding distance threshold, it means that the object is very close, and the shielding state of the infrared light beam is “with an object”. If the actual shielding distance of the infrared light beam is greater than the first effective shielding distance threshold, it means that the object is very far away, and the shielding state of the infrared light beam is “without an object”. The first effective shielding distance threshold can be set to any value in the range of 10 cm to 30 cm.

[0072] S23, determining the individual shielding state of the earphone box according to the shielding state of each of the multiple infrared light beams.

[0073] In this case, according to the blocking state of each of the plurality of infrared beams, the individual blocking state of the earphone box can be determined in various ways. For example, if the blocking state of all the infrared beams is "blocked", it is determined that the individual blocking state of the earphone box is "blocked". For another example, if the blocking state of all the infrared beams is "not blocked", it is determined that the individual blocking state of the earphone box is "not blocked". For another example, if the blocking state of part of the infrared beams is "blocked" and the blocking state of the other part of the infrared beams is "not blocked", the individual blocking state of the earphone box can be determined according to the blocking state of a larger number of infrared beams. For another example, if the number of infrared beams with the blocking state "blocked" is equal to the number of infrared beams with the blocking state "not blocked", the individual blocking state of the earphone box can be set to "uncertain", for example, or other states.

[0074] The embodiment of the present application can improve the accuracy of the individual blocking state of the earphone box by determining the individual blocking state of the earphone box according to the blocking state of each of the plurality of infrared beams, and provides a technical solution for performing a predetermined operation without contact, avoids the technical problem of inaccurate recognition caused by misidentification of user operation, and can reduce unnecessary power consumption caused by misoperation of the earphone box, save energy, solve the problem of user disturbance caused by abnormal function of the earphone caused by misidentification, and improve the user experience of using the earphone.

[0075] In one embodiment, each of the plurality of infrared beams has a different digital signal code and constitutes a customized beam group. After the step S211 in the above embodiment and before the step S22, the individual blocking detection further includes a step S212.

[0076] S212, controlling the infrared receiving end in the earphone box to identify whether the plurality of infrared beams reflected back by the blocking object are consistent with the customized beam group according to the digital signal code, and if so, performing the step of determining the blocking state of each of the plurality of infrared beams.

[0077] The infrared sensor can further include an infrared receiving end.

[0078] The infrared receiving end refers to an electronic device that converts infrared beam signals into electrical signals and performs demodulation and decoding, and its core function is to detect and identify specific infrared beams emitted by the paired infrared transmitting end, and to realize the conversion of optical signals to digital signal codes.

[0079] The plurality of infrared beams emitted by the infrared transmitting end can have different digital signal codes. The plurality of infrared beams with different digital signal codes can be, for example, infrared beam 1, infrared beam 2, and infrared beam 3, which constitute a customized beam group.

[0080] After the infrared emission end periodically emits the customized beam group (also known as customized triplet, beam triplet, etc.) of "infrared beam 1, infrared beam 2, infrared beam 3" as specified, the customized beam group encounters an obstruction and is reflected back to be received and processed by the infrared receiving end. The infrared receiving end can identify whether the multiple infrared beams reflected back by the obstruction are consistent with the customized beam group according to the digital signal coding. For example, if the multiple infrared beams reflected back by the obstruction are also "infrared beam 1, infrared beam 2, infrared beam 3" according to the digital signal coding, it is determined that the multiple infrared beams are consistent with the customized beam group. For another example, if the multiple infrared beams reflected back by the obstruction are "infrared beam 1, infrared beam 3" according to the digital signal coding, it is determined that the multiple infrared beams are inconsistent with the customized beam group. If the multiple infrared beams reflected back by the obstruction are consistent with the customized beam group, the step of determining the obstruction state of each of the multiple infrared beams is performed, that is, step S22.

[0081] The embodiment of the present application can further improve the accuracy of the individual obstruction state of the earphone box by emitting a customized beam group composed of multiple infrared beams with different digital signal coding from the infrared emission end, and identifying whether the multiple infrared beams reflected by the obstruction are consistent with the customized beam group according to the digital signal coding by the infrared receiving end. A technical solution for performing a predetermined operation without contact is provided, which avoids the technical problem of inaccurate identification caused by misidentification of user operation, and can reduce unnecessary power consumption caused by misoperation of the earphone box, save energy, solve the problem of user disturbance caused by abnormal functions of the earphone due to misidentification, and thus improve the user experience of using the earphone.

[0082] In one embodiment, the individual obstruction state of the earphone box includes invalid obstruction, valid obstruction, and continuous movement of the obstruction. In the above embodiment S23, determining the individual obstruction state of the earphone box according to the obstruction state of each of the multiple infrared beams includes S231, S232, and S233.

[0083] S231, if the obstruction state of each of the multiple beams is no obstruction, it is determined that the individual obstruction state of the earphone box is invalid obstruction.

[0084] For example, if the obstruction state of each of the multiple beams is no obstruction without setting the customized beam group, it is determined that the individual obstruction state of the earphone box is invalid obstruction.

[0085] For another example, if the obstruction state of each of the infrared beams 1, 2, and 3 is no obstruction after setting the customized beam group, for example, the customized beam group is "infrared beam 1, infrared beam 2, infrared beam 3", it is determined that the individual obstruction state of the earphone box is invalid obstruction.

[0086] S232, if the blocking states of the plurality of light beams are all blocked, determining that the individual blocking state of the earphone case is valid blocking.

[0087] For example, if the blocking states of the plurality of light beams are all blocked without setting the customized light beam group, it is determined that the individual blocking state of the earphone case is valid blocking.

[0088] For example, if the blocking states of the plurality of light beams are all blocked without setting the customized light beam group, it is determined that the individual blocking state of the earphone case is valid blocking.

[0089] S233, if the blocking state of at least one light beam of the plurality of light beams is unblocked and the blocking state of at least another light beam is blocked, determining that the individual blocking state of the earphone case is continuous blocking of the blocking object.

[0090] For example, if the blocking state of at least one light beam of the plurality of light beams is unblocked and the blocking state of at least another light beam is blocked without setting the customized light beam group, it is determined that the individual blocking state of the earphone case is continuous blocking of the blocking object.

[0091] For example, if the blocking state of at least one light beam of the plurality of light beams is unblocked and the blocking state of at least another light beam is blocked without setting the customized light beam group, it is determined that the individual blocking state of the earphone case is continuous blocking of the blocking object.

[0092] The present application embodiment can further improve the flexibility of the individual blocking state of the earphone case by determining three different individual blocking states of the earphone case according to the blocking states of the plurality of light beams, and further improve the accuracy of performing the predetermined operation, avoid the technical problem of inaccurate recognition caused by misrecognition of the user operation, and reduce unnecessary power consumption caused by misoperation of the earphone case, save energy, solve the problem of user disturbance caused by abnormal function of the earphone caused by misrecognition, and improve the user experience of using the earphone.

[0093] Figure 3 FIG. 1 is a flowchart of a method for controlling an earphone case based on a blocking state according to an application embodiment.

[0094] S31, multiple separate blocking detections are performed on whether there is an obstacle near the earphone case at multiple times, and multiple separate blocking states of the earphone case corresponding to the multiple times are obtained, wherein one separate blocking detection at one time obtains one separate blocking state, and the multiple separate blocking states constitute a blocking state change sequence reflecting changes in the blocking state.

[0095] First, define a customized beam group composed of infrared beams 1, 2, and 3 with different digital signal encodings.

[0096] Next, the infrared transmitting end on the earphone charging case periodically transmits a customized beam group composed of infrared beams 1, 2, and 3. The customized beam triplet will be reflected back when encountering an obstacle and be received and processed by the infrared receiving end. The infrared receiving end identifies the customized beam group customized by the transmitting end according to the digital signal encoding. The infrared ranging software module identifies whether the customized beam group encounters an effective block according to the beam transmission time, return time, and first effective blocking distance threshold S, and the specific calculation method is the same as or similar to that in the foregoing embodiment. The separate blocking state can be defined to include the following three states. State 1 is "no obstacle within the first effective blocking distance threshold S". The determination method of state 1 is that infrared beams 1, 2, and 3 all encounter invalid blocking. State 2 is "there is an obstacle within the first effective blocking distance threshold S". The determination method of state 2 is that infrared beams 1, 2, and 3 all encounter effective blocking. State 3 is "the obstacle within the first effective blocking distance threshold S is continuously moving". The determination method of state 3 is that at least one of the three infrared beams 1, 2, and 3 encounters effective blocking, and at least one other encounters invalid blocking.

[0097] The infrared ranging software module analyzes the return time and state of the customized beam triplet, identifies the state of the obstacle in front of the earphone case, and determines the multiple separate blocking states of the earphone case corresponding to the multiple times. In the first separate blocking detection, the separate blocking state of the earphone case is determined to be "state 1: no obstacle". In the second separate blocking detection, the separate blocking state of the earphone case is determined to be "state 2: there is an obstacle". In the third separate blocking detection, the separate blocking state of the earphone case is determined to be "state 3: the obstacle is continuously moving". In the fourth separate blocking detection, the separate blocking state of the earphone case is determined to be "state 1: no obstacle". The multiple separate blocking states constitute a blocking state change sequence reflecting changes in the blocking state, and the blocking state change sequence is "state 1 (for t1 time) -> state 2 (for t2 time) -> state 3 (for t3 time) -> state 1 (for t1 time)".

[0098] S32, when the sequence of the shielding state changes conforms to the sequence of the predetermined state corresponding to the predetermined operation, controlling the earphone case to perform the predetermined operation.

[0099] When the identified sequence of shielding state changes embodying shielding state changes conforms to the sequence of the predetermined state corresponding to the screen lighting operation, it is considered that the user issues the predetermined operation of waking up and lighting the screen. After the infrared ranging software module completes the identification of the operation of waking up and lighting the screen, it notifies the system UI (User Interface, referred to as UI) to light the screen, that is, to light the screen. The system UI refers to a software module related to the screen display on the earphone case.

[0100] In one embodiment, the separate shielding detection includes the following S41 and S42.

[0101] S41, controlling the laser device in the earphone case to emit and receive a monochromatic laser beam.
