Description

Technical Field

[0001] The present invention relates to the technical field of microphones, and in particular to a method for preventing microphones from being lost and for recovering them after they are lost. Background Art

[0002] At present, with the rise of live streaming, there is a device that matches a microphone and a speaker. There is a storage compartment for the microphone inside the speaker. However, in actual use and in daily use, due to the small size of the microphone, it is often difficult to find the microphone because you don’t know where to put it.

[0003] In patent 202321097477.7, a speaker with a storage function is proposed. It has a microphone storage function, can charge the microphone device, and can be used for outdoor square dancing, etc. However, since the main usage environment of this type of microphone is outdoors or in a square, if it is lost, it is not easy to find it unless there is a positioning chip inside the microphone.

[0004] Because most users of this type of product are outdoor personnel and the elderly, they are also prone to not promptly storing the microphone with the speaker after use. This results in the microphone being lost after a long time or being left somewhere when in use, but not being able to recall where it is, resulting in the microphone being lost and unable to be found.

[0005] In patent 201711238484.3, a method, device, wireless microphone and storage medium for retrieving a wireless microphone are proposed. When a microphone retrieval instruction is received, the Bluetooth signal of the user's mobile device is searched through the Bluetooth adapter on the wireless microphone. When the signal is not found, the current position of the wireless microphone is obtained through the positioning system on the wireless microphone, and the current position of the wireless microphone is uploaded to the server through a network connection to share the current position of the wireless microphone with the user's mobile device. When the wireless microphone is lost, the user is provided with a more accurate position of the wireless microphone, thereby improving the efficiency of retrieving the wireless microphone, thereby avoiding economic losses to the user and improving the user experience.

[0006] However, the above method can only be used to search for headphones through APPs such as mobile phone terminals, and can only be actively controlled to search, and the corresponding software on the mobile phone needs to be opened to search. However, in the prior art, the APP of TWS headphones does not have an active search function, and is not suitable for audio equipment. The audio body of the audio equipment will not be lost, and it is very large. It is mainly used to prevent the microphone from being lost when singing. If the microphone is found to be lost, the audio equipment is actively opened to search, but the microphone may not be found. The lost point may be in the square where you sing, and it cannot be found in this case. Summary of the invention

[0007] The present invention provides a microphone anti-lost reminder and a method for finding the lost microphone, which is used to solve the problem that the microphone is not stored together with the speaker in time after use, resulting in the microphone being unable to be found after a long time or being left somewhere when used but unable to recall where it is, resulting in the microphone being unable to be found after being lost.

[0024] When the speaker receives a shutdown command and the microphone is not plugged into the speaker, an anti-loss pop-up window is generated.

[0025] In combination with the first aspect, the microphone storage compartment is provided with a first constant current detection terminal and a second constant current detection terminal; wherein,

[0026] When the speaker receives a shutdown command, the first constant current detection end receives a contact response from the microphone, performs a first constant current information detection, and generates an anti-lost alarm when no constant current information is detected; wherein,

[0027] The first constant current information detection includes preset constant current charging information detection and constant current cycle information detection;

[0028] The second constant current detection end is used to determine whether constant current information exists when receiving a contact response from the microphone when no shutdown command is received, and to turn off the alarm mechanism of the sound when constant current information exists;

[0029] The constant current information includes constant current charging information and constant current cycle information.

[0034] The over-distance alarm enhancement mechanism is used to generate continuous over-distance pop-up windows when the connection range of the microphone and speaker exceeds the warning distance;

[0035] The over-distance disconnection mechanism is used to generate a disconnection pop-up window and disconnection voice when the connection range of the microphone and speaker exceeds the disconnection distance.

[0036] In combination with the first aspect, the long-range mechanism responds to the signal strength of the speaker and the microphone; wherein,

[0037] The sound is used to respond to the signal strength energy value at the current warning distance;

[0038] The connection distance between the current speaker and the microphone is calculated according to the signal strength energy value, and a distance curve of the connection distance is generated. The distance curve is associated with the over-distance mechanism.

[0055] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0056] In conjunction with the accompanying drawings, a microphone anti-lost reminder and lost recovery method provided by the embodiment of the present application is described in detail through specific embodiments and application scenarios. The microphone and the speaker provided with a microphone storage compartment are provided with a display screen, as shown in the attached drawings. Figure 1 As shown, the method includes:

[0057] Respond to the alarm signal from the microphone and display an alarm pop-up window on the speaker's display screen;

[0058] The alarm pop-up window includes: at least one of: an anti-lost pop-up window, an out-of-distance pop-up window, and a lost pop-up window;

[0059] Generate a first alarm signal according to the anti-lost pop-up window, where the first alarm signal is used to indicate that the microphone is not inserted into the microphone storage compartment;

[0060] According to the over-range pop-up window, a second alarm signal is generated, where the second alarm signal is used to indicate that the microphone is out of the usage range;

[0061] According to the lost pop-up window, respond to the retrieval instruction, and display the microphone location map through the display screen when the retrieval instruction is received.

[0062] The principle of the above technical solution is:

[0063] As attached Figure 1 and attached Figure 2 As shown, this application is mainly used in the following three scenarios when it is actually implemented:

[0064] Scenario 1: When the device is turned off, the microphone is not inserted into the storage bin, and an anti-loss pop-up window is generated. The pop-up window shows that the microphone is not inserted into the storage bin, and reminds the user to put the microphone back into the storage bin in time after use to prevent loss.

[0065] Scenario 2: When using a microphone, if the distance between the microphone and the speaker exceeds the normal usage range, the speaker will automatically send out an alarm voice and remind the user whether he has left the microphone behind and retrieve it in time to prevent loss.

[0066] Scenario 3: When the microphone is lost, when you forget where you left it, activate the microphone retrieval button on the speaker, and the microphone will indicate its location through sound alarm and light. The microphone of the present invention has light alarm function and voice alarm function.

[0067] For the first scenario:

[0068] In the specific implementation of this application, the storage compartment of the box is equipped with an insertion detection device (the detection scheme is Hall sensor, infrared sensor, contact sensor, gravity sensor). When the microphone is inserted into the storage compartment, the detection device can detect that the microphone has been inserted. When our speaker is shut down, if it is detected that both microphones have been inserted into the product, it will be shut down directly. If it is detected that both microphones are not inserted or any of the microphones is not inserted, the user is reminded in the following three ways:

[0069] (1) A pop-up window will appear on the screen to remind the user that the microphone is not in the storage compartment. Please insert the microphone. If you want to continue shutting down the device, please click the Confirm button. If you do not want to shut down the device, please click the Cancel button.

[0070] (2) A voice reminds the user that the microphone is not inserted into the storage compartment. If you need to continue shutting down, please click the confirmation button. If you do not want to shut down, click the cancel button. The screen pops up the shutdown confirmation button and cancel button.

[0071] (3) A pop-up window on the screen reminds the user that the microphone is not in the recycle bin. Please insert the microphone. If you want to continue shutting down, please click the confirmation key, or click the cancel key if you do not want to shut down. The speaker also makes a sound to remind the user. A pop-up window on the screen reminds the user that the microphone is not in the recycle bin. Please insert the microphone. If you want to continue shutting down, please click the confirmation key, or click the cancel key if you do not want to shut down. When the user inserts both microphones into the storage bin as prompted, the product automatically continues the shutdown operation.

[0072] For the second scenario:

[0073] After the microphone is connected to the speaker, the speaker can know the signal strength of the connection to judge the distance between the microphone and the speaker. The normal use range of the microphone is set in the program. When the distance between the microphone and the speaker exceeds the set use range.

[0074] (1) A pop-up window will pop up on the speaker screen to remind you that the microphone is out of range. Please make sure that the microphone is within the range and use the "off" button. Click the "off" button to close the pop-up window. When the distance between the microphone and the speaker continues to increase, the pop-up window will pop up again. When the microphone and the speaker exceed the connection distance, the pop-up window will remind you to disconnect due to the excessive distance.

[0075] (2) The speaker will remind you that the microphone is out of range. Please ensure that the microphone is used within the range. When the distance between the microphone and the speaker continues to increase, the speaker will remind you again. When the microphone and the speaker exceed the connection distance, the speaker will disconnect you.

[0076] (3) A pop-up window will appear on the speaker display to remind you that the microphone is out of range. Please ensure that the microphone is within the range of use. Use the "Close" button and the speaker will sound a reminder. Click the "Close" button to turn off the pop-up reminder and the sound reminder.

[0077] Specific alarms include microphone sound alarm, microphone light alarm, microphone sound and light alarm, and microphone and audio reminder methods.

[0078] In the third scenario:

[0079] There is a microphone retrieval button on the speaker display screen. When the microphone retrieval button is turned on.

[0080] The microphone light reminds you of the location of the microphone, the microphone sound reminds you of your location, the microphone light and sound indicate your location, a map displays the location of the microphone on the audio screen, the microphone sound reminds you, and a map displays the location of the microphone on the audio screen.

[0081] The beneficial effects of the above technical solution are:

[0082] The present invention adopts different detection methods for the situation that the microphone of the audio system is not inserted into the storage bin, is used at an excessive distance, and the microphone is lost. Different alarm pop-up windows and alarm signals are used to remind the user that the microphone is not in the storage bin, or the usage distance exceeds a safe range. In addition, when a lost pop-up window appears, the user is assisted in retrieving the microphone of the audio system. The above three alarm pop-up windows can ensure that the microphone will not be lost after use. Even if it is lost, the loss can be quickly known and the scope of the loss can be clearly identified. Combined with the excessive distance pop-up window and the lost pop-up window, the scope of the lost microphone can be determined when the microphone is lost. Within the corresponding range, the microphone position map can be used to locate the lost position of the microphone, such as direction guidance or red dot marking.

[0083] In some embodiments, the audio storage compartment is provided with an insertion detection device; wherein,

[0084] The insertion detection device is used to respond to the microphone insertion signal and start the corresponding insertion mode when the microphone is not inserted; wherein,

[0085] Insertion modes include screen pop-up mode, sound reminder mode and sound pop-up synchronization mode;

[0086] When the speaker receives a cancel command, the corresponding mode is turned off and the speaker is powered off;

[0087] When the speaker receives the confirmation command, it continues in the corresponding mode and the speaker alarms.

[0088] The principle of the above technical solution is:

[0089] In the above technical solution, when the user finishes using the speaker and turns off the speaker, the insertion detection device in the speaker, which includes but is not limited to one of Hall detection, infrared detection and contact detection, automatically responds to the trigger, and reminds the user by voice reminder or screen pop-up that the microphone is not inserted into the speaker. The specific mode reminder mode is set by the user, and then the speaker receives the user's instructions to control the shutdown and alarm of the speaker. When the speaker alarms, the corresponding lost command is started to generate a selection trigger interface for the retrieval command.

[0090] The effects of the above technical solution are:

[0091] The present invention can automatically sense whether the microphone inside the audio storage compartment is in an unplugged state, and generate a corresponding pop-up window to remind the user that the microphone is not plugged in.

[0092] In some embodiments, the speaker determines the alarm limit value of the microphone and the speaker by the signal strength of the connection between the microphone and the speaker; wherein,

[0093] The microphone and the speaker are configured with a normal working signal strength range, and the minimum signal strength value within the signal strength range is the alarm limit value.

[0094] The principle of the above technical solution is:

[0095] During the use of the speaker, the sensing distance between the speaker and the microphone is determined based on the signal strength, and the signal strength is related to the real-time distance between the microphone and the speaker. If there are too many interference factors between the microphone and the speaker, such as the presence of signal interference devices such as walls, the real-time signal strength range becomes smaller, the connection range between the microphone and the speaker is smaller, and the alarm distance is also smaller. However, in open areas, there are no obstacles that interfere with or block the signal between the microphone and the speaker, so the signal strength range is large.

[0096] The beneficial effects of the above technical solution are:

[0097] Because the more open the area, the easier it is to find the microphone. The more obstacles and signal blocking factors there are, the harder it is to find the microphone.

[0098] In some embodiments, the alarm signal includes a microphone sound alarm, a microphone light alarm, and a display screen pop-up window alarm.

[0099] The principle of the above technical solution is:

[0100] The alarm modes set in this application include microphone sound alarm, microphone light alarm, and pop-up alarm on the display screen on the speaker.

[0101] In some embodiments, the anti-lost pop-up window is applied when the speaker is turned off; wherein,

[0102] When the speaker receives the shutdown command, the microphone is already plugged into the speaker and the speaker is turned off;

[0103] When the speaker receives a shutdown command and the microphone is not plugged into the speaker, an anti-loss pop-up window is generated.

[0104] The principle of the above technical solution is:

[0105] The anti-loss pop-up window of the present invention is mainly used when the speaker is turned off. When the speaker is turned off, if the microphone is plugged into the speaker, the speaker will be turned off directly. However, when the speaker is turned off, if the microphone is not plugged into the speaker, the speaker will automatically generate an anti-loss pop-up window unless the user actively triggers the speaker to shut down again.

[0106] In some embodiments, the microphone storage compartment is provided with a first constant current detection terminal and a second constant current detection terminal; wherein,

[0107] When the speaker receives a shutdown command, the first constant current detection end receives a contact response from the microphone, performs a first constant current information detection, and generates an anti-lost alarm when no constant current information is detected; wherein,

[0108] The first constant current information detection includes preset constant current charging information detection and constant current cycle information detection;

[0109] The second constant current detection end is used to determine whether constant current information exists when receiving a contact response from the microphone when no shutdown command is received, and to turn off the alarm mechanism of the sound when constant current information exists;

[0110] The constant current information includes constant current charging information and constant current cycle information.

[0111] The principle of the above technical solution is:

[0112] In traditional technology, the microphone storage compartment transfers electrical energy to the microphone's battery through physical contact. There is usually a set of metal contact points between the charging compartment and the microphone or headset. When the microphone is placed in the charging compartment, the contact points are connected to each other, and current flows through these contact points to charge the microphone battery. This set of metal contact points is only related to the charging response and has no other functions.

[0113] As attached Figure 3 As shown, the present application is configured with two constant current detection ends in the microphone storage compartment, namely the first constant current detection end and the second constant current detection end; when the speaker receives the shutdown command, the first constant current detection end will receive the contact response of the microphone. At this time, there is a contact response, but it is not necessarily the microphone insertion, which is used to prevent others from inserting non-microphone objects into the storage compartment, and in this case, the current consumption of the microphone is detected to determine whether the first constant current information is generated. If the first constant current information is not detected, an anti-lost alarm is generated. Among them, the first constant current information includes preset constant current charging information detection and constant current circulation information detection, which is used to detect whether the microphone is in a constant current charging state and a constant current circulation state, but not charged. The function of the second constant current detection end is to generate the second constant current information when the shutdown command is not received and the contact response of the microphone is received, and to turn off the alarm mechanism of the speaker when the second constant current information exists. At the same time, the second constant current information also includes constant current charging information and constant current circulation information. When the microphone is lost during use, the first constant current detection end will immediately start the anti-lost alarm system after detecting the first constant current information, prompting the user to find the lost microphone in time. When the second constant current detection end receives the contact response of the microphone, it will generate a second constant current information and turn off the alarm mechanism of the audio in this case. In this way, while ensuring the normal use of the audio, frequent triggering due to false alarms can be avoided. The advantage of the present invention is that it can improve the reliability of the anti-loss system through multiple constant current detection ends, ensure that the loss of the microphone can be accurately identified in a variety of situations, and can perform more sophisticated anti-loss control through different constant current information such as preset constant current charging information and constant current cycle information, thereby improving the user experience.

[0114] In some embodiments, the over-distance pop-up window is applied after the speaker and microphone are connected; wherein,

[0115] When the speaker is connected to the microphone, the speaker sets the over-range mechanism according to the microphone parameters;

[0116] The over-distance mechanism includes over-distance warning mechanism, over-distance disconnection mechanism and over-distance alarm reinforcement mechanism;

[0117] The over-distance warning mechanism is used when the connection range of the microphone and the speaker reaches the warning distance and activates the over-distance pop-up window;

[0118] The over-distance alarm enhancement mechanism is used to generate continuous over-distance pop-up windows when the connection range of the microphone and speaker exceeds the warning distance;

[0119] The over-distance disconnection mechanism is used to generate a disconnection pop-up window and disconnection voice when the connection range of the microphone and speaker exceeds the disconnection distance.

[0120] The principle of the above technical solution is:

[0121] The over-distance pop-up window of the present invention is suitable for the process in which the user uses the speaker to sing, that is, when the speaker is turned on. At this time, the over-distance mechanism will generate the first over-distance pop-up window according to the over-distance warning, over-distance disconnection and over-distance reinforcement, when it detects that the connection range has reached the warning distance and may exceed the final connection distance, to prompt the possible over-distance; at this time, if the warning distance is exceeded, continuous over-distance pop-up windows will be generated; finally, the over-distance alarm reinforcement mechanism will generate a disconnection pop-up window and emit a disconnection voice after the distance between the speaker and the microphone exceeds the final connection distance.

[0122] The beneficial effects of the above technical solution are:

[0123] The present invention can display different pop-up windows and alarms of different levels when the distance between the microphone and the speaker reaches the warning distance and the disconnection distance, and when the distance is between the warning distance and the disconnection distance, so as to remind the user at all times.

[0124] In some embodiments, the long-range mechanism is responsive to the signal strength of the speaker and the microphone; wherein,

[0125] The sound is used to respond to the signal strength energy value at the current warning distance;

[0126] The connection distance between the current speaker and the microphone is calculated according to the signal strength energy value, and a distance curve of the connection distance is generated. The distance curve is associated with the over-distance mechanism.

[0127] The principle of the above technical solution is:

[0128] The "over-distance mechanism" of the present application is an anti-loss mechanism that calculates the connection distance between the speaker and the microphone by analyzing the signal strength energy value between the two, and generates a corresponding distance curve based on this distance. This mechanism can better adapt to usage in different environments and scenarios. In this mechanism, the speaker is used to monitor the current signal strength energy value to determine the actual distance between the microphone and the speaker. This distance value will be used to calculate a distance curve, which will be associated with all other over-distance mechanism settings as part of the over-distance mechanism. This distance curve will allow the system to better understand the relative position between the microphone and the speaker, so that a more accurate connection distance prediction can be established between them. In addition, the over-distance mechanism can also use the signal strength energy value between the microphone and the speaker to calculate other parameters related to the distance between them, such as sound intensity or sound source size.

[0129] The over-the-distance mechanism can be implemented through the following steps:

[0130] First, ensure that the relative position between the microphone and the speaker is known, and build a three-dimensional coordinate system to achieve distance coordinate measurement, providing measurement and collection for subsequent calculation of distance-related parameters.

[0131] Then, the microphone device collects the sound signals in the room in real time and transmits the signals to the central processing unit. At the same time, the audio equipment plays specific test sounds so that the microphone can receive sound signals from different distances and angles.

[0132] The central processing unit processes the received sound signal and extracts the signal strength energy value. By analyzing the changes in the signal strength energy value, the distance between the microphone and the speaker can be preliminarily determined.

[0133] Based on the relationship between the signal strength energy value and the distance, a mathematical model is established. Through the model calculation, the actual distance between the microphone and the speaker can be obtained. Common models include logarithmic attenuation model, linear attenuation model, etc.

[0134] Sound intensity and sound source size calculation: Based on the distance between the microphone and the speaker, combined with the physical characteristics of sound propagation, the sound intensity and sound source size can be further calculated. For example, by measuring the sound pressure level and frequency characteristics of the sound, the size and direction of the sound source can be estimated.

[0135] These parameters can be used as parameters to further optimize the distance curve to provide more accurate connection distance prediction. By combining the signal strength energy value between the speaker and the microphone and the actual distance between them, the over-range mechanism can provide a flexible and reliable anti-loss mechanism, making the use of music players and other devices more convenient and safer.

[0136] In some embodiments, the lost pop-up window is in response to a map modeling thread, which is used to perform map modeling according to the microphone usage range and generate a location map; wherein,

[0137] The location map includes a first map and a second map. The first map is used to identify the track map of the microphone usage track and usage range, and the second map is used to identify the real-time direction map of the microphone through the GPS inside the microphone.

[0138] The location map marks the last used location of the microphone.

[0139] In some implementations, generating a location map further comprises:

[0140] According to the usage trajectory of the microphone, the map points are determined and a Gaussian probability grid map of the microphone position is generated;

[0141] Determine the matching degree between the last position of the microphone and different grids of the Gaussian probability grid map, sort the microphone position probabilities according to the matching degree, and generate the probability light spots of the microphones at different positions on the display screen; wherein,

[0142] The color depth of the probability light spot is used to represent the probability that the corresponding position is the microphone loss position.

[0143] The principle of the above technical solution is:

[0144] The generation of a location map in this application refers to analyzing the usage trajectory of the microphone on the basis of the above method, determining the location of the microphone and generating a Gaussian probability map. In this Gaussian probability map, each location is assigned a corresponding Gaussian distribution, indicating the probability of the location being the location where the microphone is lost. The map can be used to help calibrate where the microphone may be lost and provide users with more specific instructions so that they can find the lost microphone more easily. "Microphone position probability sorting" is to sort the microphone positions by comparing the microphone positions with the Gaussian probability map, and generate probability light spots of the microphones at different positions on the display screen according to the sorting results. The color depth of these probability light spots is used to indicate the probability that the corresponding position is the location where the microphone is lost. The darker the color, the greater the probability that the position will be the location where the microphone is lost, and vice versa.
