[0051] Specifically, the charging box circuit further comprises a communication interface electrically connected to the controller, and the controller communicates with the wireless earphone through the communication interface, including reading the power of the wireless earphone. The communication interface can be a GPIO (general purpose input / output) interface for single-wire communication or a UART (universal asynchronous receiver / transmitter) interface for serial communication.

[0052] Based on the above hardware architecture, an embodiment of a control method of a charging box is provided.

[0053] Please refer to Figure 4 , Figure 4 For the first embodiment of the control method of the charging box, the control method of the charging box comprises the following steps:

[0054] Step S100, detecting whether the audio data forwarded by the wireless earphone is received, wherein the audio data forwarded by the wireless earphone is sent by the audio playing terminal to the wireless earphone;

[0055] Step S200, controlling the first loudspeaker to play the audio data when the audio data forwarded by the wireless earphone is received.

[0056] Under normal circumstances, the wireless earphone will play the audio data received from the audio playing terminal through the second loudspeaker, which is the earphone playing mode. However, in some cases, the user cannot use the audio playing function of the earphone, such as: the user needs to charge the wireless earphone due to low power, and interrupts the use of the wireless earphone; or the user needs to rest due to long wearing of the wireless earphone, and suspends the wearing of the wireless earphone. In these cases, the user cannot continue to listen to the audio through the earphone playing mode.

[0057] The embodiment of the present application adopts the method of further forwarding the audio data sent by the audio playing terminal received by the wireless earphone, forwarding the audio data from the wireless earphone to the charging box, and playing the audio data through the first loudspeaker in the charging box, to realize the function of playing audio by the charging box. Specifically, the second audio interface of the wireless earphone is electrically connected to the first audio interface of the charging box, the Bluetooth chip transmits the audio data to the first audio processing module of the charging box through the second audio interface and the first audio interface, and the audio data is output through the first loudspeaker after being converted and amplified by the first audio processing module.

[0058] The audio playing system of the embodiment of the present application adds the first loudspeaker in the existing charging box, so that the charging box can play the audio data forwarded by the wireless earphone through the first loudspeaker, thereby forming the effect of the Bluetooth sound box, and meeting the demand of the user that the user can also listen to songs without wearing the wireless earphone.

[0059] The control method of the charging box of the embodiment of the present application forwards the audio data of the wireless earphone to the charging box, and then plays the audio data through the first loudspeaker of the charging box, thereby realizing the function of playing audio by the charging box, providing two modes of earphone playing and charging box playing, and enabling the user to select and use according to the need, meeting the demand of the user that the user can also listen to songs without wearing the wireless earphone, and enhancing the functionality of the audio playing system composed of the charging box and the wireless earphone, and being able to adapt to more use cases.

[0060] Further, based on the first embodiment of the control method of the charging box, the second embodiment of the control method of the charging box is provided, and before the step of detecting whether the audio data forwarded by the wireless earphone is received, the second embodiment further includes:

[0061] Step S300, detecting whether the wireless earphone is placed in the charging box;

[0062] Step S400, when it is detected that the wireless earphone is placed in the charging box, performing the step of detecting whether the audio data forwarded by the wireless earphone is received.

[0063] In order to facilitate the user operation and facilitate the user to freely switch the earphone playing mode and the charging box playing mode, the embodiment of the present application determines that the earphone playing mode is switched to the charging box playing mode by judging whether the wireless earphone is placed in the charging box. The method of detecting whether the wireless earphone is placed in the charging box can adopt the method in the prior art, such as sensor detection. After the wireless earphone is placed in the charging box, the wireless earphone sends an audio start instruction to the charging box, and notifies the controller in the charging box to start the first audio processing module. The embodiment switches the audio playing mode by the earphone entering the box, which is simple and easy to operate and convenient for the user.

[0064] Moreover, in order to facilitate the connection between the second audio interface of the wireless earphone and the first audio interface of the charging box, in the embodiment, the first audio interface is located on the charging compartment wall of the charging box, and the second audio interface is located on the surface of the wireless earphone. When the wireless earphone is placed in the charging box, the first audio interface of the charging box is docked with the second audio interface of the wireless earphone. At this time, the Bluetooth chip in the wireless earphone can transmit the audio data to the first audio processing module of the charging box through the second audio interface and the first audio interface, and output the audio through the first loudspeaker.

[0065] Further, based on the first to third embodiments of the charging case control method, a fourth embodiment of the charging case control method is provided, in which the step of detecting whether the wireless earphone is placed in the charging case is followed by:

[0066] Step S500, decoding the audio data.

[0067] The data rate generated after the audio data is digitized is quite large, and the data volume is even larger. In order to improve the utilization and transmit more information under the limited channel capacity, the audio data is generally encoded and compressed. In this embodiment, the first audio processing module includes a first audio codec module and a first audio amplifier. After the wireless earphone sends the signal encoded and compressed into digital audio to the first audio codec module through the first audio interface, the first audio codec module can decode the digital audio back to analog audio, which is then amplified by the first audio amplifier and sent to the first loudspeaker for output.

[0068] Further, based on the first to third embodiments of the charging case control method, a fourth embodiment of the charging case control method is provided, in which the step of detecting whether the wireless earphone is placed in the charging case is followed by:

[0069] Step S600, charging the wireless earphone when it is detected that the wireless earphone is placed in the charging case.

[0070] When the user uses the charging case to play the audio function, the wireless earphone is placed in the charging case, so the charging interface of the wireless earphone is connected with the power supply interface of the charging case, and the charging case can charge the wireless earphone at the same time. This allows the user to charge and listen to music at the same time, saving time and being convenient, and meeting more user needs.

[0071] Further, based on the first to fourth embodiments of the charging case control method, a fifth embodiment of the charging case control method is provided, in which the wireless earphone includes a main earphone and a secondary earphone, and the step of detecting whether the audio data forwarded by the wireless earphone is received is preceded by:

[0072] Step S310, detecting whether the main earphone and the secondary earphone are placed in the charging case at the same time;

[0073] Step S311, when it is detected that the main earphone and the secondary earphone are placed in the charging case at the same time, performing the step of detecting whether the audio data forwarded by the wireless earphone is received.

[0074] In existing wireless earphones, TWS earphones, also known as true wireless Bluetooth earphones, include two independent earphones, which are divided into a main earphone (usually the right ear) and a secondary earphone. A Bluetooth chip is arranged in each of the main earphone and the secondary earphone. When audio is played, the main earphone communicates with an audio playing terminal (such as a smart phone, a tablet, a computer, etc.) through Bluetooth to obtain audio data from the audio playing terminal, and then transmits the audio data to the secondary earphone through Bluetooth. The main earphone and the secondary earphone are synchronized through Bluetooth to realize synchronous playing of the audio by the main earphone and the secondary earphone, forming a stereo system with left and right channels. The main earphone and the secondary earphone can be used separately, that is, single channel. Usually, a user uses the main earphone with one ear or uses the main earphone and the secondary earphone at the same time, and uses the secondary earphone with one ear in special cases. Since the audio is transmitted from the main earphone, the power consumption of the main earphone is greater, which leads to a shorter battery life of the main earphone than that of the secondary earphone. When the user charges the main earphone, the main earphone automatically transmits the audio data to the secondary earphone so that the user can continue to use the secondary earphone. At this time, the main earphone is placed in the charging box, and the charging box only charges the main earphone and does not play audio. Alternatively, the user only uses the main earphone and places the secondary earphone in the charging box for charging. At this time, the charging box also does not play audio. Only when the user places the main earphone and the secondary earphone in the charging box at the same time, the charging box determines that the user needs to use the charging box to play audio, automatically starts the function of playing audio, receives the audio data from the main earphone, and outputs the audio data through the first loudspeaker.

[0075] Further, based on the fifth embodiment of the control method of the charging box, a sixth embodiment of the control method of the charging box is provided. In the sixth embodiment, after the step of controlling the first loudspeaker to play the audio data, the method further comprises:

[0076] In step S312, when it is detected that the main earphone or the secondary earphone is taken out of the charging box, the first loudspeaker is controlled to stop playing the audio data.

[0077] When the main earphone and the secondary earphone are placed in the charging box for charging, the charging box plays the audio data forwarded by the main earphone. When the user takes out the main earphone or the secondary earphone from the charging box, the charging box determines that the user needs to use the wireless earphone to play audio. At this time, the charging box automatically closes the function of playing audio, and controls the first loudspeaker to stop playing the audio, so as to avoid the wireless earphone and the charging box playing audio at the same time, affecting the user's single-ear use of the earphone, and ensuring the user's good use experience.

[0078] Further, based on the first to fourth embodiments of the control method of the charging box, a seventh embodiment of the control method of the charging box is provided. In the seventh embodiment, the wireless earphone includes a left earphone and a right earphone. Before the step of detecting whether the audio data forwarded by the wireless earphone is received, the method further comprises:

[0079] Step S320, detecting whether the left earphone and / or the right earphone is put into the charging box.

[0080] Step S321, when detecting that the left earphone and / or the right earphone is put into the charging box, performing the step of detecting whether the audio data forwarded by the wireless earphone is received.

[0081] In the existing wireless earphone, part of the earphone does not distinguish the main earphone and the auxiliary earphone, and the independent left earphone and the right earphone are connected with the audio playing terminal through the respective Bluetooth chip, and synchronously receive the audio data transmitted by the audio playing terminal. Generally, the user wears the left earphone and the right earphone with both ears for use. Since the left earphone and the right earphone are both respectively receiving the audio data, the power consumption of the left earphone and the right earphone is roughly the same, and the endurance time of the two is roughly equal. Or, for the neck line type earphone, the left earphone and the right earphone are connected through the wire harness, connected with the audio playing terminal through the built-in Bluetooth module, and also powered by the built-in earphone battery. In the above two cases, the user generally puts the left earphone and the right earphone into the charging box at the same time for charging. When the charging box detects that the left earphone and the right earphone are put in at the same time or any one of the earphones is put in, the charging box will determine that the user needs to use the charging box to play audio, and will automatically start the audio playing function, receive the audio data from the Bluetooth chip of the left earphone or the right earphone, and output through the first loudspeaker. By setting the single earphone into the box, the earphone playing mode can be switched to the charging box playing mode, which is convenient for the user to operate.

[0082] Further, based on the seventh embodiment of the control method of the charging box, an eighth embodiment of the control method of the charging box is proposed. In the eighth embodiment, after the step of controlling the first loudspeaker to play the audio data, the eighth embodiment further comprises:

[0083] Step S322, when detecting that the left earphone and the right earphone are taken out from the charging box, controlling the first loudspeaker to stop playing the audio data.

[0084] In this embodiment, because the wireless earphone does not distinguish the main earphone and the auxiliary earphone, the user generally wears the left earphone and the right earphone with both ears for use, therefore, as long as any one of the left earphone and the right earphone is left in the charging box, the charging box will determine that the user needs to use the charging box to play audio, and will continue to play the audio. Only when the user takes out the left earphone and the right earphone from the charging box at the same time, the charging box will determine that the user needs to use the wireless earphone to play audio, at this time, the charging box will close the audio playing function, and control the first loudspeaker to stop playing the audio through the controller.

[0085] Further, please refer to Figure 5Based on the first to eighth embodiments of the control method of the charging box described above, a ninth embodiment of the control method of the charging box is proposed, wherein after the step of controlling the first speaker to play the audio data, the ninth embodiment further comprises:

[0086] Step S610, obtaining the battery power of the charging box;

[0087] Step S620, when the battery power is lower than the preset threshold, controlling the first speaker to stop playing the audio data.

[0088] Because the power consumption of the charging box is relatively large after starting to play audio, the battery power of the charging box needs to be consumed, and at the same time, the charging box also needs to charge the wireless earphone, which also needs to consume the battery power of the charging box. In order to ensure the charging function of the charging box, the priority of the charging function of the charging box is higher than that of the audio playing function in this embodiment. The priority is determined by setting a preset threshold. Specifically, the comparison program written in the controller of the charging box is pre-set with a power threshold, and the controller detects the battery power of the charging box in real time or at regular intervals, and compares the detected battery power with the preset threshold. When the detected battery power is lower than the preset threshold, the controller controls the first audio processing module and the first speaker to stop working, so as to stop the audio playing function of the charging box and only keep the charging function of the charging box, so as to realize the priority of charging the wireless earphone when the battery power of the charging box is low, and ensure the basic charging function of the charging box.

[0089] Further, please refer to Figure 6 Based on the first to ninth embodiments of the control method of the charging box described above, a tenth embodiment of the control method of the charging box is proposed, wherein after the step of controlling the first speaker to play the audio data, the tenth embodiment further comprises:

[0090] Step S700, when the volume adjustment instruction is received, adjusting the volume of the first speaker according to the volume adjustment instruction.

[0091] In order to adjust the volume of the played audio while the charging box is playing audio, the volume adjustment instruction can be sent to the charging box to achieve this. After the controller of the charging box receives the volume adjustment instruction, the first audio processing module processes the received audio data according to the information of the volume adjustment instruction, and then outputs the audio processed according to the adjustment instruction through the first speaker. This embodiment can adjust the volume of the played audio by sending the volume adjustment instruction to the charging box, and improve the user's experience.

[0092] Further, based on the tenth embodiment of the control method of the charging box, an eleventh embodiment of the control method of the charging box is provided, in which whether a volume adjustment instruction is accepted is detected by determining the pressed state of the corresponding volume adjustment button on the charging box.

[0093] Specifically, a corresponding volume adjustment button can be arranged on the charging box to send a volume adjustment instruction to the controller of the charging box. The volume adjustment button is electrically connected to the controller. By pressing the corresponding volume adjustment button, the user can adjust the volume, which facilitates the user's control of audio playback and effectively improves the user's experience.

[0094] The technical solutions in the embodiments of the present application have at least the following technical effects or advantages:

[0095] The control method of the charging box according to the embodiments of the present application realizes the function of the charging box playing audio by forwarding the audio data of the wireless earphone to the charging box and playing the audio data through the first loudspeaker of the charging box, provides two modes of earphone playback and charging box playback, and enables the user to select and use according to needs, thereby enhancing the functionality of the audio playback system composed of the charging box and the wireless earphone and enabling the system to adapt to more use cases.

[0096] The present application also provides a control method of a wireless earphone, which is used with a charging box. The charging box is internally provided with a loudspeaker. The control method of the wireless earphone comprises the following steps: receiving audio data sent by an audio playback terminal; and forwarding the audio data to the charging box for playing the audio data by the loudspeaker in the charging box when a forwarding instruction is received.

[0097] The technical problem to be solved by the embodiments of the present application is that the user often needs to charge the Bluetooth earphone due to low battery level during use, which interrupts the use of the Bluetooth earphone. Or the user needs to rest due to ear fatigue caused by wearing the Bluetooth earphone for a long time, which temporarily suspends the wearing of the Bluetooth earphone. These situations all result in the inability to continue playing audio when the wireless earphone is not worn.

The Bluetooth chip, the analog switch, the second audio processing module and the second loudspeaker are connected in sequence through an I2S bus, the second audio interface is connected with the analog switch through the I2S bus, and the second audio interface adopts an I2S interface and is electrically connected with the first audio interface of the charging box.

[0101] The Bluetooth chip is used for the Bluetooth connection between the wireless earphone and an audio playing terminal (such as a mobile phone, a tablet computer, a notebook computer, etc.), so as to realize the communication between the wireless earphone and the audio playing terminal, so that the audio playing terminal sends a music file to the wireless earphone in the form of audio data, the second audio processing module sends the received audio data to the second loudspeaker after processing, and the audio data is output through the second loudspeaker.
