[0020] Technologies and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such technologies and equipment should be considered part of the specification.
[0021] In all the examples shown and discussed herein, any specific values should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.
[0022] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.
[0023] The following describes in detail the headphones provided in the embodiments of this disclosure with reference to the accompanying drawings. Typically, the headphones can be TWS headphones. Through the headphones provided in the embodiments of this disclosure, it is possible to play two audio data streams from different applications simultaneously with one pair of headphones.
[0024] See Figure 1 This disclosure exemplarily illustrates headphones.
[0025] The system architecture of the headphones provided in this disclosure embodiment can be found in [reference needed]. Figure 1 The earphone 1 may include a main earphone 10 and a secondary earphone 20. The main earphone 10 may include a first terminal communication module 11 and a first processing module 12, and the secondary earphone 20 may include a second terminal communication module 21 and a second processing module 22.
[0026] The first terminal communication module 11 may be a first Bluetooth module, used for communication connection between the main earphone 10 and the audio source device.
[0027] The second terminal communication module 21 can be a second Bluetooth module, used for communication connection between the secondary earphone 20 and the audio source device.
[0028] The aforementioned audio source device can be a mobile phone, tablet computer, desktop computer, wearable device, or any other device with audio output function. This embodiment does not limit this.
[0029] In this embodiment, the main earphone 10 receives a first audio data stream through the first terminal communication module 11 and processes the first audio data stream through the first processing module 12, and the secondary earphone 20 receives a second audio data stream through the second terminal communication module 21 and processes the second audio data stream through the second processing module 22.
[0030] The first and second audio data streams originate from different applications on the audio source device. Furthermore, the first and second audio data streams can have different priorities, with the first audio data stream having a higher priority than the second. For example, the first audio data stream could be a call audio stream, while the second audio stream could be a media playback audio stream. The call audio stream originates from a call application, while the media playback audio stream originates from a multimedia application such as a music application. The call audio stream can have a higher priority than the media playback audio stream; however, users can also set the priorities of different audio data streams according to their needs.
[0031] For example, the audio source device can send a high-priority call audio data stream to the main earpiece 10 and a low-priority media playback audio data stream to the secondary earpiece 20. The main earpiece 10 can receive the call audio data stream sent by the audio source device through the first terminal communication module 11 and process the call audio data stream through the first processing module 12. The secondary earpiece 20 can receive the media playback audio data stream sent by the audio source device through the second terminal communication module 21 and process the call audio data stream through the second processing module 22.
[0032] In this embodiment, the headphones include a main earphone and a secondary earphone. The main earphone includes a first terminal communication module and a first processing module, and the secondary earphone includes a second terminal communication module and a second processing module. The main earphone can receive a first audio data stream through the first terminal communication module and process the first audio data stream through the first processing module. The secondary earphone can receive a second audio data stream through the second terminal communication module and process the second audio data stream through the second processing module. The first audio data stream and the second audio data stream come from different audio sources, thus enabling a single earphone to play two different audio data streams simultaneously, improving the user experience.
[0033] In one embodiment, when the earphone 1 is in a first working mode, the main earphone 10 receives a first audio data stream from the audio source device through the first terminal communication module 11, and the secondary earphone 20 receives a second audio data stream from the audio source device through the second terminal communication module 21.
[0034] The first working mode can be a high-performance working mode.
[0035] For example, when headset 1 is in high-performance mode, the audio source device can send a high-priority call audio data stream to the main headset 10 and a low-priority media playback audio data stream to the secondary headset 20. The main headset 10 can receive the call audio data stream sent by the audio source device through the first terminal communication module 11. The secondary headset 20 can receive the media playback audio data stream sent by the audio source device through the second terminal communication module 21.
[0036] In this embodiment, the main earphone and the secondary earphone can simultaneously receive audio data streams from different applications sent by the audio source device, realizing true audio multitasking, and the two audio streams do not interfere with each other, resulting in lower latency.
[0037] In one embodiment, refer to Figure 2 The main earphone 10 also includes a first device communication module 13, as shown in the reference. Figure 3 The secondary earphone 20 also includes a second device communication module 23.
[0038] The first device communication module 13 can be a first ISM (Industrial Scientific Medical) wireless transmission module, and the second terminal communication module 23 can be a second ISM wireless transmission module.
[0039] In this embodiment, when the earphone 1 is in the second working mode, the main earphone 10 receives a third audio data stream from the audio source device through the first terminal communication module 11, and forwards the third audio data stream to the secondary earphone 20 through the first device communication module 13 and the second device communication module 23.
[0040] The third audio data stream can be the same as or different from the first and second audio data streams.
[0041] The second operating mode can be a power-saving mode.
[0042] In one example, when earphone 1 is in power-saving mode, the main earphone 10 can receive a third audio data stream from the audio source device through the first terminal communication module 11, and forward the third audio data stream to the secondary earphone 20 through the first device communication module 13. The secondary earphone 20 can receive the third audio data stream through the second device communication module 23.
[0043] In this embodiment, by receiving one audio data stream through the main earphone and forwarding the audio data stream to the secondary earphone, it is possible to achieve playback of the same audio data stream by both the main and secondary earphones while further reducing the power consumption of the earphones.
[0044] In one embodiment, the first processing module 12 is further configured to: monitor the audio output status of the audio source device; control the headphones to enter the first working mode when the audio output status is detected to be a dual-channel audio data stream; and control the headphones to enter the second working mode when the audio output status is detected to be a single-channel audio data stream.
[0045] In this embodiment, the first processing module 12 can monitor the audio output status of the audio source device. When the audio source output status indicates a dual-channel audio data stream, it can control the headphones 1 to enter a high-performance mode. When the audio output status indicates a single-channel audio data stream, it can control the headphones 1 to enter a power-saving mode, so that the headphones 1 can work in different operating modes to receive audio data streams.
[0046] In one embodiment, refer to Figure 2 The main earphone 10 also includes a first physiological signal detection module 14, as shown in the reference. Figure 3 The secondary earphone 20 also includes a second physiological signal detection module 24.
[0047] The first physiological signal detection module 14 is used to collect the first physiological characteristic signal of the wearer of the main earphone 10. The second physiological signal detection module 24 is used to collect the second physiological characteristic signal of the wearer of the secondary earphone 20. The first processing module 12 is further used to determine whether the earphone 1 is for single-person or dual-person use based on the first and second physiological characteristic signals.
[0048] The first physiological signal detection module 14 is used to detect the physiological signals of the wearer of the main earphone 10. The first physiological signal detection module 14 may include bioelectric electrodes, a photoplethysmography (PPG) sensor, and a skin conductance electrode. The bioelectric electrodes are used to collect the wearer's electrocardiogram (ECG) signals. The PPG sensor is used to collect the wearer's photoplethysmography (PPG) signals. The skin conductance electrode is used to collect the wearer's skin conductance response signals. That is, the first physiological characteristic signal may include ECG signals, PPG signals, and skin conductance response signals.
[0049] The second physiological signal detection module 24 is used to detect the physiological signals of the wearer of the secondary earphone 20. The second physiological signal detection module 24 may include bioelectric electrodes, a PPG sensor, and a skin conductance electrode. The bioelectric electrodes are used to collect the electrocardiogram (ECG) signal of the wearer of the secondary earphone. The PPG sensor is used to collect the photoplethysmography (PPG) wave signal of the wearer of the secondary earphone. The skin conductance electrode is used to collect the skin conductance response signal of the wearer of the secondary earphone. That is, the second physiological characteristic signal may include ECG signal, PPG wave signal, and skin conductance response signal.
[0050] In one example, the first processing module 12 can acquire the first physiological feature signal collected by the first physiological signal detection module 14 and the second physiological feature signal collected by the second physiological signal detection module 24, and calculate the similarity between the first physiological feature signal and the second physiological feature signal. If the similarity meets the preset conditions, it can be determined that the earphone 1 is for single-person use; if the similarity does not meet the preset conditions, it can be determined that the earphone 1 is for dual-person use.
[0051] The preset conditions may include a similarity greater than or equal to a first preset similarity, which can be preset based on experience and scenario. When the similarity is greater than or equal to the first preset similarity, it indicates that the first physiological feature signal and the second physiological feature signal are physiological feature signals of the same user.
[0052] This embodiment can determine whether the earphone is currently being used by a single person or two people based on the physiological characteristic information collected by the main earphone and the physiological characteristic information collected by the secondary earphone.
[0053] In one embodiment, the first processing module 12 is further configured to: when the earphone 1 is used by a single person, if there are two audio data streams, configure the high-priority audio data stream to the main earphone 10, and configure the low-priority audio data stream to the secondary earphone 20 according to the user's interaction with the secondary earphone. When the earphone 1 is used by two people, if there are two audio data streams, first determine the target earphone from the main earphone 10 and the secondary earphone 20, configure the high-priority audio data stream to the target earphone for playback, and configure the low-priority audio data stream to the other earphone.
[0054] The target earphone can be the earphone used by the main user, and the pre-stored physiological characteristic signals can be the physiological characteristic signals of the main user. By comparing the physiological characteristic signals collected by the main earphone 10 and the secondary earphone 20 with the pre-stored physiological characteristic signals, the earphone used by the main user can be determined as the target earphone from the main earphone 10 and the secondary earphone 20. For example, the physiological characteristic signals can be compared with the pre-stored physiological characteristic signals to obtain the similarity between the two. If the similarity is greater than or equal to a second preset similarity, the main earphone 10 or the secondary earphone 20 that collected the physiological characteristic signals is determined as the target earphone.
[0055] Scenario 1: If the headset is used by a single person and the audio device simultaneously supports both call audio and media playback audio streams (e.g., listening to music in a music app while simultaneously answering a call in a phone app), the call audio stream has higher priority than the media playback audio stream. Therefore, the audio source device can configure the call audio stream to the primary headset 10. In this case, the user can double-click the secondary headset 20, and the audio source device can then configure the media playback audio stream to the secondary headset, thus achieving dual audio output in single-user mode.
[0056] Scenario 2: If the earphones are used by two people, and the audio device simultaneously has two audio data streams: a call audio stream and a media playback audio stream (e.g., listening to music while simultaneously answering a call using a call app), the call audio stream has a higher priority than the media playback audio stream. In this case, the similarity between the physiological feature signal collected by the main earphone 10 and pre-stored physiological feature signals, and the similarity between the physiological feature signal collected by the secondary earphone 20 and pre-stored physiological feature signals, can be obtained. For example, if the similarity between the physiological feature signal collected by the main earphone and the pre-stored physiological feature signal is greater than a second preset similarity, the main earphone can be designated as the target earphone. The audio source device can allocate the higher-priority call audio data stream to the main earphone and the lower-priority media playback audio data stream to the secondary earphone.
[0057] In other words, the headset will force the call audio stream to be routed to the headset used by the primary user, while forcing the media audio stream to continue playing on the headset used by the other user. The other user cannot hang up the primary user's call through their own headset, and the primary user cannot deprive the other user of their music through their own headset, thus achieving audio privacy and operational isolation.
[0058] In one embodiment, refer to Figure 2 The main earphone 10 also includes a first wearing detection module 15, as shown in the reference. Figure 3 The secondary earphone 20 also includes a second wearing detection module 25.
[0059] The first wearing detection module 15 is used to collect a first wearing status signal of the main earphone 10; the second wearing detection module 25 is used to collect a second wearing status signal of the secondary earphone 20; the first processing module 12 is further used to control the first physiological signal detection module 14 to collect the first physiological feature signal and control the second physiological signal detection module 24 to collect the second physiological feature signal when the first wearing status signal indicates that the main earphone 10 is in a wearing state and the second wearing status signal indicates that the secondary earphone 20 is in a wearing state.
[0060] The first wearing detection module 15 can collect the wearing status signal of the main earphone 10 so as to determine whether the main earphone 10 is in the wearing state based on the wearing status signal.
[0061] The second wearing detection module 25 can collect the wearing status signal of the secondary earphone 20 so as to determine whether the secondary earphone 20 is in the wearing state based on the wearing status signal.
[0062] In this embodiment, the first physiological characteristic signal is collected through the main earphone and the second physiological characteristic signal is collected through the secondary earphone only when both the main earphone and the secondary earphone are being worn, so as to reduce the power consumption of the main earphone and the secondary earphone.
[0063] The above embodiments mainly describe the differences between the various embodiments. As long as the different optimization features between the various embodiments are not contradictory, they can be combined to form a better embodiment. For the sake of brevity, they will not be elaborated here.
