[0048] The present application embodiment provides an audio playback switching method, referring to Figure 1 As shown, Figure 1 It is a flowchart of the first embodiment of the audio playback switching method of the present application.

[0049] Here, exemplary embodiments are described in detail, and examples thereof are shown in the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application.

[0050] In recent years, the portability, privacy, immersion and high performance of headphones have made them the main tool for people to enjoy music and sound. However, due to the characteristics of headphones themselves, such as certain damage to the ears and battery life limitations, people need to choose other methods such as smart speakers to replace headphones to play audio. Taking headphones and smart speakers as an example, when switching from headphones to smart speakers, you need to take off the headphones, connect the smart speakers with a mobile phone or computer, and then use the smart speakers to play audio; when the smart speakers switch to headphones, you need to connect the headphones with a mobile phone or computer, and then wear the headphones to play audio; or the headphones and smart speakers can be connected to the mobile phone or computer at the same time, but the switching requires additional operation. Most headphones are charged by wire. If you need to charge the headphones when switching, you need to add the action of plugging in the cable for charging. The above switching methods have many steps, which will invest a lot of time and cost, and the user experience is not good.

[0051] In order to solve the technical defect of poor user experience caused by the poor switching efficiency of existing audio playback devices, the present application provides an audio playback switching method, system, device and storage medium.

[0052] The audio playback switching method of the present application is applied to the earphone device 10, and the earphone device 10 and the speaker device 30 are respectively communicatively connected with the playback source device, and the speaker device 30 is provided with a charging stand 20 for placing the earphone device 10.

[0053] The audio playback switching method of this application includes:

[0054] Step S10: In response to the headphone removal signal, sending an audio transmission stop signal to the playback source device.

[0055] In this embodiment, the earphone device 10 and the speaker device 30 provided in this application can communicate with the playback source device through a wireless connection. When the user wears the earphone device 10 and plays the audio signal uploaded by the playback source device, the environment sensor provided on the inner side of the earmuff of the earphone device 10 detects whether the earphone device 10 is taken off by the user. If the environment sensor detects that the earphone device 10 is taken off by the user, the earphone device 10 responds to the earphone removal signal sent by the environment sensor to send an audio stop transmission signal to the playback source device to achieve instant interruption of audio playback, effectively avoiding unnecessary audio playback, thereby bringing users a more intelligent and humanized audio experience. At the same time, it also lays a solid foundation for subsequent audio playback switching operations, allowing users to enjoy smoother and seamless audio switching services without manual intervention.

[0056] It should be noted that the earphone device 10 provided in the present application can be understood as a headset, the speaker device 30 can be understood as a smart speaker, the playback source device can be understood as a mobile phone, a tablet or a computer, etc., and the environmental sensor can be understood as a capacitive sensor and a photosensitive sensor.

[0057] Step S20: After the playback source device stops uploading the audio signal to the headphone device 10 in accordance with the audio stop transmission signal, it is detected that the headphone device 10 is placed on the charging bracket 20 for charging, and the charging signal of the headphone device 10 is uploaded to the playback source device, so that the playback source device switches the transmission link of the audio signal from the headphone device 10 to the speaker device 30 in accordance with the charging signal.

[0058] In this embodiment, after the playback source device stops uploading the audio signal to the earphone device 10 in accordance with the audio stop transmission signal, the earphone device 10 is placed on the charging bracket 20 of the speaker device 30 so that the charging device can automatically charge the earphone device 10; next, the earphone device 10 automatically uploads a charging signal reflecting that it is in a charging state to the playback source device; then, the playback source device can immediately and seamlessly switch the transmission link of the audio signal from the earphone device 10 to the speaker device 30 based on the received charging signal, without the need for the user to manually intervene in the search, pairing or adjustment of the device settings, thereby greatly simplifying the switching operation steps of the existing audio playback device, shortening the switching operation time, and significantly improving the switching efficiency of the audio playback, thereby eliminating the troubles caused by cumbersome and time-consuming manual operations and connection problems or audio interruptions that may be caused by improper operations, so as to provide users with a smoother, seamless and comfortable audio experience.

[0059] It should be noted that the earphone device 10 is provided with a wireless charging receiving chip, a charging management chip and a battery which are electrically connected in sequence; the speaker device 30 is provided with a wireless charging transmitting chip and a power management chip which are electrically connected in sequence.

[0060] In a specific embodiment, refer to Figure 2 , Figure 2 : is a schematic diagram of the structure of the audio switching system involved in the embodiment of the present application. The present application is provided with a fixedly connected charging bracket 20 on one side of the speaker device 30, and the charging bracket 20 can place the headphone device 10. Exemplarily, when the built-in magnetic induction coil of the charging bracket 20 and the magnetic induction coil of the internal resistance of the headphone device 10 generate an induced electromotive force, it is determined that the headphone device 10 is placed on the charging bracket 20, and then, the power supply signal provided by the power management chip is sent to the headphone device 10 via the wireless charging transmitting chip. At this time, the headphone device 10 receives the power supply signal sent by the wireless charging transmitting chip through the wireless charging receiving chip, and according to the electrical connection between the wireless charging receiving chip and the charging management chip, the wireless charging receiving chip sends the power supply signal to the charging management chip, so that the charging management chip provides the power supply signal to the battery of the headphone device 10, thereby realizing automatic charging of the headphone device 10 through the wireless interaction between the wireless charging receiving chip and the wireless charging transmitting chip without the need for human intervention.

[0061] In summary, the present application provides an audio playback switching method that optimizes the audio playback switching method, significantly improving the convenience and efficiency of users switching audio playback between the headphone device 10 and the speaker device 30. Specifically, when the user takes off the earphone, the earphone device 10 automatically sends an audio stop transmission signal to the playback source device in response to the earphone removal signal, so that the playback source device can immediately stop uploading the audio signal to the earphone device 10 according to the audio stop transmission signal, thereby avoiding unnecessary audio output; next, the earphone device 10 can be automatically charged through the charging bracket 20 of the speaker device 30 without manual intervention. Once the earphone device 10 determines that it is placed on the charging bracket 20 of the speaker device 30 for charging, it automatically uploads a charging signal reflecting that the earphone device 10 is in a charging state to the playback source device; then, the playback source device can immediately and seamlessly switch the transmission link of the audio signal from the earphone device 10 to the speaker device 30 according to the received charging signal, without the user manually intervening in searching, pairing or adjusting device settings, thereby greatly simplifying the switching operation steps of the existing audio playback device, shortening the switching operation time, and significantly improving the switching efficiency of audio playback, thereby eliminating the troubles caused by cumbersome and time-consuming manual operations and connection problems or audio interruptions that may be caused by improper operations, so as to provide users with a smoother, seamless and comfortable audio experience.

[0062] Furthermore, based on the first embodiment of the audio playback switching method of the present application, a second embodiment of the audio playback switching method of the present application is proposed.

[0063] Further, in some feasible embodiments, a capacitive sensor and a photosensitive sensor are provided inside the earmuff of the headphone device 10. In the above step S10: in response to the headphone removal signal, an audio stop transmission signal is sent to the playback source device. The audio playback switching method further includes the following implementation steps:

[0064] Step A10: After the earmuff contacts the body surface of the wearer, the actual ambient light intensity collected by the photosensitizer and the initial capacitance signal collected by the capacitance sensor are obtained.

[0065] In this embodiment, when the inner side of the earmuff of the headphone device 10 is in close contact with the body surface of the wearer, the light sensor and the capacitive sensor provided on the inner side of the earmuff will immediately start the collaborative monitoring mechanism. Specifically, the light sensor will immediately collect the actual ambient light intensity on the inner side of the earmuff, and based on the capacitive sensor, measure the capacitance change after the earmuff contacts the body surface of the wearer, and generate an initial capacitance signal to reflect the initial wearing characteristics of the headphone device 10.

[0066] Step A20: When the actual ambient light intensity matches the preset non-wearing light intensity threshold, a plurality of actual capacitance signals collected by the capacitance sensor within a preset monitoring time are averaged to obtain a capacitance average signal.

[0067] In this embodiment, the actual ambient light intensity is compared with a preset non-worn light intensity threshold. If the actual ambient light intensity is within the light intensity range corresponding to the non-worn light intensity threshold, it is determined that the actual ambient light intensity matches the non-worn light intensity threshold, thereby performing averaging processing on multiple actual capacitance signals collected by the capacitance sensor within a preset monitoring time to eliminate accidental errors and improve data stability and reliability, so that the capacitance average signal can be accurately obtained, thereby enhancing the accuracy of subsequent wearing status detection.

[0068] In another embodiment, if the actual ambient light intensity is not within the light intensity range corresponding to the not-worn light intensity threshold, the actual ambient light intensity does not match the preset not-worn light intensity threshold, that is, the headphone device 10 is in the worn state.

[0069] Step A30: Calculate the capacitance difference between the initial capacitance signal and the capacitance mean signal, and determine the wearing detection result according to the capacitance difference.

[0070] In this embodiment, the capacitance difference between the initial capacitance signal and the capacitance mean signal is calculated, and the capacitance difference can directly reflect the contact state between the earmuff and the wearer's body surface; next, the wearing detection result determined by the capacitance difference can further determine whether the user is wearing the headphone device 10, thereby realizing intelligent identification of whether the headphone device 10 is worn by the user without manual intervention.

[0071] Furthermore, in some other feasible embodiments, the above step A30: determining the wearing detection result according to the capacitance difference may also include the following implementation steps:

[0072] Step A301: Detect whether the capacitance difference is within a preset removal threshold range;

[0073] In this embodiment, the earphone device 10 compares the capacitance difference with a preset removal threshold range, thereby providing an accurate judgment basis for subsequent wearing status detection.

[0074] Step A302: If the capacitance difference is not within the removal threshold range, determining that the wearing detection result is that the earphone device 10 is in the wearing state.

[0075] In this embodiment, if the capacitance difference is not within the preset removal threshold range, the wearing detection result is determined to be that the earphone device 10 is in a wearing state, thereby ensuring the continuity of audio transmission and greatly improving the user experience.

[0076] Step A303: If the capacitance difference is within the removal threshold range, determining that the wearing detection result is that the earphone device 10 is in an unworn state, and generating the earphone removal signal according to the unworn state.

[0077] In this embodiment, if the capacitance difference is within the preset removal threshold range, the wearing detection result is determined to be that the earphone device 10 is in an unworn state, and a timely response is made to the unworn state so as to instantly generate an earphone removal signal, thereby achieving instant response and intelligent processing of changes in wearing status.

[0078] Furthermore, based on the first embodiment and the second embodiment of the audio playback switching method of the present application, a third embodiment of the audio playback switching method of the present application is proposed. The audio playback switching method provided in the present application can also be applied to a speaker device 30, wherein the speaker device 30 and the headphone device 10 are respectively connected to the playback source device in communication, and the speaker device 30 is provided with a charging stand 20 for placing the headphone device 10.

[0079] The audio playback switching method provided in this application may include the following implementation steps:

[0080] Step B10: When the charging bracket 20 charges the headphone device 10, the audio signal sent by the playback source device is played; wherein,

[0081] The headphone device 10 is used to, in response to a headphone removal signal, send an audio stop transmission signal to the playback source device, detect that the headphone device 10 is placed on the charging bracket 20 for charging after the playback source device stops uploading the audio signal, and upload the charging signal of the headphone device 10 to the playback source device;

[0082] The playback source device is used to stop uploading the audio signal to the headphone device 10 according to the audio stop transmission signal; and to switch the transmission link of the audio signal from the headphone device 10 to the speaker device 30 according to the charging signal.

[0083] In this embodiment, when the charging stand 20 charges the earphone device 10, the source device communicates with the earphone device 10 through the playback source device, and the playback source device receives the charging signal sent by the earphone device 10 reflecting that it is in a charging state. At this time, the playback source device switches the transmission link of the audio signal from the earphone device 10 to the speaker device 30; then, through the electrical connection between the speaker device 30 and the playback source device, the speaker device 30 receives the audio signal uploaded by the playback source device and plays the audio signal, thereby ensuring the continuity and high quality of the audio playback, allowing the user to enjoy the audio experience transmitted by the playback source device through the speaker device 30 even during the charging of the earphone device 10, thereby significantly improving the user experience.

[0084] In a specific embodiment, the earphone device 10 and the speaker device 30 provided in the present application can both communicate with the playback source device through a wireless connection. When the user wears the earphone device 10 and plays the audio signal uploaded by the playback source device, the environment sensor provided on the inner side of the earmuff of the earphone device 10 detects whether the earphone device 10 is taken off by the user. If the environment sensor detects that the earphone device 10 is taken off by the user, the earphone device 10 responds to the earphone removal signal sent by the environment sensor to send an audio stop transmission signal to the playback source device, thereby realizing an instant interruption of the audio playback, effectively avoiding unnecessary audio playback, and thus providing the user with a more intelligent and user-friendly audio experience. At the same time, it also lays a solid foundation for subsequent audio playback switching operations, allowing users to enjoy a smoother and seamless audio switching service without manual intervention. Next, after the playback source device stops uploading the audio signal to the earphone device 10 in accordance with the audio stop transmission signal, the earphone device 10 is placed on the charging stand 20 of the speaker device 30 so that the charging device can automatically charge the earphone device 10; next, the earphone device 10 automatically uploads a charging signal reflecting that it is in a charging state to the playback source device; then, the playback source device can immediately and seamlessly switch the transmission link of the audio signal from the earphone device 10 to the speaker device 30 based on the received charging signal, without the need for the user to manually intervene in the search, pairing or adjustment of device settings, thereby greatly simplifying the switching operation steps of the existing audio playback device, shortening the switching operation time, and significantly improving the switching efficiency of the audio playback, thereby eliminating the troubles caused by cumbersome and time-consuming manual operations and connection problems or audio interruptions that may be caused by improper operations, so as to provide users with a smoother, seamless and comfortable audio experience.

[0085] Furthermore, in some feasible embodiments, after the above step B10: playing the audio signal sent by the playback source device, the audio playback switching method further includes the following implementation steps:

[0086] Step B101: sending a power supply signal to the earphone device 10 .

[0087] In this embodiment, when the speaker device 30 plays the audio signal sent by the playback source device, it will also provide a power supply signal to the headphone device 10 through the wireless charging transmitter chip arranged inside the speaker. Without the need for additional user operation, the headphone device 10 is charged by the power supply signal output by the speaker device 30, and the audio signal sent by the playback source device is also played through the speaker device 30, thereby achieving the dual convenience of audio enjoyment and charging of the headphone device 10, greatly improving the user experience.

[0088] Step B102: If the power feedback signal of the power supply signal sent by the headphone device 10 is not received within the preset response time, it is determined that the headphone device 10 is detached from the charging bracket 20, and the speaker device 30 is triggered to send a speaker pause playback instruction to the playback source device; wherein,

[0089] The playback source device is used to switch the transmission link of the audio signal from the speaker device 30 to the earphone device 10 according to the charging completion signal sent by the earphone device 10 after stopping uploading the audio signal to the earphone device 10 according to the speaker pause playback instruction.

[0090] In this embodiment, if the speaker device 30 does not receive the power feedback signal of the power supply signal sent by the headphone device 10 within the preset response time, it automatically confirms that the headphone device 10 has been detached from the charging bracket 20, and immediately triggers the speaker device 30 to send a speaker pause playback instruction to the playback source device, thereby effectively avoiding the redundant situation that the speaker device 30 continues to play audio when the headphone device 10 is not in the charging state, reducing unnecessary energy consumption, and maintaining precise control of audio playback. Subsequently, the playback source device will intelligently and seamlessly switch the transmission link of the audio signal from the speaker device 30 back to the headphone device 10 according to the charging completion signal sent by the headphone device 10. The entire process does not require manual intervention by the user, which not only simplifies the operation process, but also ensures the continuity and smoothness of audio playback, bringing users a more intelligent, convenient and efficient audio experience.

[0091] In addition, the present application also provides an audio playback switching system, which at least includes an earphone device 10, a speaker device 30 and a playback source device, wherein the earphone device 10 and the speaker device 30 are respectively connected to the playback source device for communication, and the speaker device 30 is provided with a charging stand 20 for placing the earphone device 10;

[0092] The headphone device 10 is used to, in response to a headphone removal signal, send an audio stop transmission signal to the playback source device, detect that the headphone device 10 is placed on the charging bracket 20 for charging after the playback source device stops uploading the audio signal, and upload the charging signal of the headphone device 10 to the playback source device;

[0093] The playback source device is used to stop uploading the audio signal to the headphone device 10 according to the audio stop transmission signal; and switch the transmission link of the audio signal from the headphone device 10 to the speaker device 30 according to the charging signal;

[0094] The speaker device 30 is used to play the audio signal sent by the playback source device when the charging bracket 20 charges the headphone device 10.

[0095] Each device module of the audio playback switching system of the present application implements the steps of the audio playback switching method of the present application as described above during operation.

[0096] Further, in some feasible embodiments, please refer to Figure 3 , Figure 3 It is a block diagram of the audio playback switching system involved in the embodiment of the present application. The headphone device 10 at least includes a headphone speaker, a headphone microphone, an audio codec, an audio signal interface, a headphone audio processing chip, a main controller, a wireless charging receiving chip, a charging management chip, a battery and a headphone end wireless connection chip; the audio codec is electrically connected to the headphone microphone, the headphone speaker, the audio signal interface and the headphone audio processing chip respectively, the headphone microphone is electrically connected to the headphone speaker, the main controller is electrically connected to the headphone audio processing chip, the wireless charging receiving chip, the charging management chip and the headphone end wireless connection chip respectively, the headphone audio processing chip is electrically connected to the headphone end wireless connection chip, and the wireless charging receiving chip is electrically connected to the battery through the charging management chip.

[0097] In this embodiment, refer to Figure 3 as well as Figure 4 , Figure 4 This is a flowchart of the smart speaker relaying audio playback involved in the embodiment of the present application. For example, the earphone device 10 is a headset, and the speaker device 30 is a smart speaker. When the headset is playing an audio signal and the headset is charging on the smart speaker charging stand 20, the audio signal played by the headset is relayed on the smart speaker, specifically including the following implementation steps:

[0098] Step 1: Both the headphones and the smart speaker are connected to the source device via wireless connection;

[0099] Step 2: When the headphones are playing music, the headphones are taken off. The sensor in the headphones detects that the headphones are taken off and notifies the MCU (Microcontroller Unit) in the headphones. The MCU sends a stop playback command to the wireless connection chip at the headphone end. The wireless connection chip at the headphone end then sends the stop playback command to the playback source device wirelessly, so that the headphones stop playing audio signals.

[0100] Step 3: Place the headphones on the charging stand 20 of the smart speaker;

[0101] Step ④: The wireless charging transmitting chip in the smart speaker recognizes the rechargeable device (i.e., headphones), and the wireless charging receiving chip in the headphones also recognizes the power supply (i.e., smart speaker). In other words, the wireless charging transmitting chip and the wireless charging receiving chip communicate successfully, and the smart speaker starts to charge the headphones.

[0102] Step ⑤: When the smart speaker starts to charge the headset, the wireless charging transmitting chip sends a notification signal to the SoC (System on Chip) in the smart speaker to inform the headset device 10 to start charging. At the same time, the charging management chip of the headset sends a charging notification signal (i.e., a charging signal) to the MCU in the headset to inform the headset to start charging;

[0103] Step ⑥: The MCU sends a charging notification command to the wireless connection chip at the headphone end, and the wireless connection chip at the headphone end sends the charging notification command to the playback source device wirelessly. The playback source device receives the charging notification command and terminates audio transmission to the headphone (i.e., terminates transmission of audio signals to the headphone);

[0104] Step 7: The SoC in the smart speaker sends an earphone charging command to the wireless connection chip on the speaker side. The wireless connection chip on the speaker side sends the earphone charging command to the playback source device wirelessly. The playback source device receives the earphone charging command and starts transmitting audio signals to the smart speaker.

[0105] Step ⑧: The headphones stop playing the audio signal, and the smart speaker starts playing the audio signal.

[0106] It should be noted that the headphone end wireless connection chip provided in the present application is a Bluetooth chip or a 2.4 GHz private protocol chip. In addition, the MCU in the headset and the headphone end wireless connection chip can be an integrated chip.

[0107] In another embodiment, in the process of relaying audio playback by the smart speaker, the process within the dotted frame line may be that the MCU in the headset can send a command to the wireless connection chip on the headset end to disconnect from the playback source device, and the headset audio playback is terminated.

[0108] Further, in some other feasible embodiments, please refer to Figure 3The speaker device 30 at least includes a speaker, a microphone array, an amplifier module, a speaker audio processing chip, a system chip, a speaker wireless communication module, a power management chip, a wireless charging transmitter chip and a DC power interface; the speaker audio processing chip is electrically connected to the amplifier module, the microphone array, the speaker wireless communication module and the system chip respectively, and the amplifier module is electrically connected to the speaker; the speaker wireless communication module and the wireless charging transmitter chip are electrically connected to the system chip respectively, and the DC power interface is electrically connected to the wireless charging transmitter chip through the power management chip.

[0109] In this embodiment, refer to Figure 3 as well as Figure 5 , Figure 5 This is a flowchart of the headphone relay audio playback involved in the embodiment of the present application. For example, the headphone device 10 is a headphone, and the speaker device 30 is a smart speaker. When the smart speaker is playing audio, the headphone is charging on the charging stand 20 of the smart speaker, and the headphone is picked up and worn, the speaker audio is relayed on the headphone, which specifically includes the following implementation steps:

[0110] Step 1: Both the headphones and the smart speaker are connected to the source device via wireless connection;

[0111] Step 2: The headset is being charged on the charging stand 20 of the smart speaker, and the smart speaker is playing audio;

[0112] Step 3: The user takes the headset off the charging stand 20 and wears it;

[0113] Step 4: The transmitting end of the wireless charging transmitting chip in the smart speaker detects that the receiving end of the wireless charging receiving chip does not exist, and sends a notification detection signal to the SoC (system chip) in the smart speaker (notifying the SoC that the receiving end of the wireless charging receiving chip does not exist). At this time, the SoC in the smart speaker sends a charging completion signal to the wireless connection chip at the speaker end, and the wireless connection chip at the speaker end sends the charging completion signal to the playback source device wirelessly. The playback source device receives the charging completion signal and stops transmitting audio to the smart speaker, and the smart speaker stops playing the audio signal;

[0114] Step 5: The wireless charging receiving chip in the headset detects that the transmitting end of the wireless charging transmitting chip does not exist, and sends a detection notification signal to the MCU (i.e., the main controller) in the headset (notifying the MCU that the transmitting end of the wireless charging transmitting chip does not exist). At this time, the MCU in the headset sends a charging completion instruction to the headphone-end wireless connection chip in the headset. The headphone-end wireless connection chip sends the charging completion instruction to the playback source device wirelessly. The playback source device receives the charging completion instruction and starts to transmit audio signals to the headset.

[0115] Step 6: Wear the headphones. The environmental sensor in the headphones detects that the headphones are being worn, notifies the MCU in the headphones, and sends the headphone wearing instruction to the wireless connection chip on the headphone end. The wireless connection chip on the headphone end then sends the headphone wearing instruction to the playback source device wirelessly, and the audio signal starts to play in the headphones.

[0116] It should be noted that Figure 3 The wireless connection chip at the speaker end and the WIFI (WIreless FIdelity) module shown constitute a wireless communication module; illustratively, the WIFI module and the wireless connection chip at the speaker end in the smart speaker can be two independent modules, or the WIFI chip and the wireless connection chip at the speaker end can be integrated in the same module. In addition, the wireless connection chip at the speaker end is a Bluetooth chip or a 2.4GHz private protocol chip.

[0117] In another embodiment, in the process of relay playback through headphones, the process within the dotted frame line may be that the SoC in the smart speaker can send a command to the wireless connection chip to disconnect from the playback source device, and the audio playback of the speaker is terminated.
