[0041] An embodiment of this application provides an acoustic system, such as Figure 1As shown, the acoustic system includes:

[0042] A cloud server 10, a headphone body 20, a headphone case 30, a first microphone 21, a second microphone 31, a first speaker 22, and a second speaker 32;

[0043] A storage groove is provided in the headphone case 30, the headphone body 20 can be stored in the storage groove, the first speaker 22 and the first microphone 21 are fixed in the headphone body 20, and the second speaker 32 and the second microphone 31 are fixed in the headphone case 30;

[0044] Wherein, the sending end of the first microphone 21 is communicatively connected to the cloud server 10, the cloud server 10 is communicatively connected to the receiving end of the second speaker 32, the sending end of the second microphone 31 is communicatively connected to the cloud server 10, and the cloud server 10 is communicatively connected to the receiving end of the first speaker 22.

[0045] In this application, by adding a speaker and a microphone in the headphone case 30 to support the user to use related functions (such as: call function, music function, conference function, etc.) based on the headphone case 30 rather than the headphones, thus avoiding the hygiene hazards caused by dirty headphones, enabling the user to share or communicate with the user wearing the headphones without obstacles, and thus facilitating the user's use of the headphones.

[0046] It should be noted that the audio stream sent by the cloud server 10 to the first speaker 22 may include at least one of: the audio stream sent by the first microphone 21 to the cloud server 10, the audio stream sent by the second microphone 31 to the cloud server 10, and the audio stream sent by an external device to the cloud server 10; similarly, the audio stream sent by the cloud server 10 to the second speaker 32 may also include at least one of: the audio stream sent by the first microphone 21 to the cloud server 10, the audio stream sent by the second microphone 31 to the cloud server 10, and the audio stream sent by an external device to the cloud server 10.

[0047] It should be noted that the microphones referred to in this application (such as the first microphone 21 and the second microphone 31) should be understood as any device capable of converting a sound signal into an electrical signal. Similarly, the speakers referred to in this application (such as the first speaker 22 and the second speaker 32) should be understood as any device capable of converting an electrical signal into a sound signal.

[0048] Exemplarily, if it is assumed that there are two users, user A and user B, where user A is the owner of the acoustic system;

[0049] Then, in an audio sharing scenario, when user A is listening to a song transmitted by a music APP based on the earphone body 20, user A shares the earphone case 30 with user B, enabling user B to share the song currently being listened to by user A through the earphone case 30. At this time, the server device corresponding to the music APP can be understood as the aforementioned external device, and the audio streams received by the first speaker 22 and the second speaker 32 are the same, specifically the audio stream sent by the external device to the cloud server 10;

[0050] In a remote conversation scenario, user A shares the earphone case 30 with user B, enabling user A and user B to have a remote conversation through the earphones and the earphone case 30. That is, the first microphone 21 in the earphone body 20 collects the human voice of user A and plays it through the second speaker 32 in the earphone case 30, and the second microphone 31 in the earphone case 30 collects the human voice of user B and plays it through the first speaker 22 in the earphone body 20. At this time, the audio stream received by the first speaker 22 is the audio stream sent by the second microphone 31 to the cloud server 10, and the audio stream received by the second speaker 32 is the audio stream sent by the first microphone 21 to the cloud server 10;

[0051] In a meeting scenario, user A, user B, and user C are all meeting participants. User A shares the earphone case 30 with user B, enabling user A and user B to receive the audio stream sent by user C based on the corresponding external device (such as a smart earphone, a smartphone, a tablet, etc.) through the earphones and the earphone case 30, or receive the audio stream sent by user A based on the earphone body 20, or receive the audio stream sent by user B based on the earphone case 30. At this time, the audio streams received by the first speaker 22 and the second speaker 32 are the same, specifically the audio stream sent by the external device to the cloud server 10 (from user C), or the audio stream sent by the first microphone 21 to the cloud server 10 (from user A), or the audio stream sent by the second microphone 31 to the cloud server 10 (from user B).

[0052] Exemplarily, the structures of the earphone body 20 and the earphone case 30 applying the acoustic system of the present application can be as Figures 2 - 4 shown, where Figure 2 is a schematic diagram of the earphone body 20 being stored in the earphone case 30. At this time, the earphone case 30 is in an open state, and the earphone body 20 is shown by a dotted line in Figure 2 ; Figure 3 is a schematic diagram of the earphone body 20; Figure 4 is a schematic diagram of the earphone case 30 in a closed state.

[0053] In one embodiment, the cloud server 10 includes an audio translation module. The transmitting end of the first microphone 21 is communicatively connected to the first port of the audio translation module. The second port of the audio translation module is communicatively connected to the receiving end of the second speaker 32. The transmitting end of the second microphone 31 is communicatively connected to the third port of the audio translation module. The fourth port of the audio translation module is communicatively connected to the receiving end of the first speaker 22;

[0054] The audio translation module is configured to: receive a first audio stream transmitted by the first microphone 21 based on the first port, send a second audio stream to the second speaker 32 based on the second port, receive a third audio stream transmitted by the second microphone 31 based on the third port, and send a fourth audio stream to the first speaker 22 based on the fourth port;

[0055] Wherein, the speech content carried by the first audio stream is the same as the speech content carried by the second audio stream, the speech content carried by the third audio stream is the same as the speech content carried by the fourth audio stream, the language of the first audio stream is different from the language of the second audio stream, and the language of the third audio stream is different from the language of the fourth audio stream.

[0056] In this embodiment, based on the setting of the audio translation module, the acoustic system of the present application can support the simultaneous interpretation function, which can expand the application scope of the acoustic system.

[0057] In application, the user can control the translation mode corresponding to the earphone body 20 and the translation mode corresponding to the earphone case 30 of the audio translation module by remotely accessing the cloud server 10. For example: set the translation mode corresponding to the earphone body 20 to the Chinese-to-English mode (which means translating the Chinese audio collected by the first microphone 21 in the earphone body 20 into English audio), and set the translation mode corresponding to the earphone case 30 to the English-to-Chinese mode (which means translating the English audio collected by the second microphone 31 in the earphone case 30 into Chinese audio).

[0058] Specifically, the first microphone 21 is configured to:

[0059] Collect a first voice signal within a first sound collection range, perform audio encoding on the first voice signal to form a first audio stream, and send the first audio stream to the first port of the audio translation module based on the Classic Bluetooth protocol. The first sound collection range is a spherical range centered on the first microphone 21 with a first set distance as the radius;

[0060] The audio translation module is configured to:

[0061] Decode the first audio stream to obtain the first voice signal, translate the first voice signal to obtain a second voice signal, perform audio encoding on the second voice signal to form a third audio stream, and send the third audio stream to the second speaker 32 based on the Bluetooth Low Energy (BLE) protocol;

[0062] The second speaker 32 is configured to:

[0063] Receive the third audio stream sent from the third port of the audio translation module based on the Bluetooth Low Energy protocol, decode the third audio stream to obtain the second voice signal, and perform audio playback based on the second voice signal.

[0064] Similarly, the second microphone 31 is configured to:

[0065] Collect a third voice signal within a second sound collection range, perform audio encoding on the third voice signal to form a second audio stream, and send the second audio stream to the second port of the audio translation module based on the Bluetooth Low Energy protocol, where the second sound collection range is a spherical range centered on the second microphone 31 with a first set distance as the radius;

[0066] The audio translation module is further configured to:

[0067] Decode the second audio stream to obtain the third voice signal, translate the third voice signal to obtain a fourth voice signal, perform audio encoding on the fourth voice signal to form a fourth audio stream, and send the fourth audio stream to the first speaker 22 based on the classic Bluetooth protocol;

[0068] The first speaker 22 is configured to:

[0069] Receive the fourth audio stream sent from the fourth port of the audio translation module based on the classic Bluetooth protocol, decode the fourth audio stream to obtain the fourth voice signal, and perform audio playback based on the fourth voice signal.

[0070] Exemplarily, as Figure 5 shown, when simultaneous interpretation is performed based on the above acoustic system, when user A (the owner of the acoustic system) is having a conversation with user B (another user different from user A and with a mother tongue different from user A), user A hands the charging case to user B.

[0071] When User B is speaking, the built-in microphone in the charging case (i.e., the second microphone 31) picks up User B's voice in real time and converts it into a voice signal (i.e., the third voice signal). After audio encoding the voice signal, it is transmitted to the cloud server 10 via BLE communication. After audio decoding by the cloud server 10, the voice signal is translated, and then the translated voice is transmitted to the earphone in real time via BT communication. Then, through the earphone speaker unit (i.e., the first speaker 22), the translated voice of User B is played to User A;

[0072] When User A is speaking, the built-in microphone in the earphone (i.e., the first microphone 21) picks up User A's voice in real time and converts it into a voice signal (i.e., the first voice signal). After audio encoding the voice signal, it is transmitted to the cloud server 10 via BT communication. After audio decoding by the cloud server 10, the voice is translated, and then the translated voice is transmitted to the charging case in real time via BLE communication. Then, through the built-in speaker unit in the charging case (i.e., the second speaker 32), the translated voice of the user is played to User B.

[0073] In one embodiment, the cloud server 10 includes an audio relay module. The input port of the audio relay module is communicatively connected to the target sending end, and the first output port of the audio relay module is communicatively connected to the audio receiving end of an external device remotely accessing the cloud server 10. The target sending end includes at least one of the sending ends of the first microphone 21 and the second microphone 31;

[0074] The audio relay module is configured to: synchronously forward a target audio stream to the external device remotely accessing the cloud server 10, where the target audio stream is the audio stream sent by the target sending end to the cloud server 10.

[0075] In this embodiment, through the setting of the audio relay module, other users who do not hold the earphone body 20 and the earphone case 30 can also timely hear the voice of the user who holds the earphone body 20 or the earphone case 30 by remotely accessing the cloud server 10. Moreover, since the number of devices allowed to remotely access the cloud server 10 is not limited, the number of users that the described acoustic system can access can be greatly expanded, further expanding the application scope of the acoustic system.

[0076] Especially in a conference scenario, based on the above settings, the earphone case 30 and / or the earphone body 20 can be used as a microphone for conference speeches, and the earphone case 30 (specifically, the second speaker 32) is used as a speaker for conference speeches. This enables the user currently speaking in the conference to freely adjust the position of the microphone for conference speeches, which greatly facilitates the use of the microphone by the participating users.

[0077] Exemplarily, the external devices remotely accessing the cloud server 10 may include at least one of the following: smart bracelet, smart bracelet, smart earphone, smart phone, tablet, smart head-mounted device.

[0078] For example, as Figure 6 shown, in a meeting scenario, the earphone microphone can collect the ambient sound 1 near the earphone microphone through near-field sound pickup and upload it to the cloud server 10 (mainly the human voice of the user speaking in the meeting), and the charging case microphone can collect the ambient sound 2 near the earphone microphone through near-field sound pickup and upload it to the cloud server 10 (mainly the human voice of the user speaking in the meeting).

[0079] When the cloud server 10 only receives the ambient sound 1, it is determined that only the earphone is working currently, and the earphone pickup content is displayed / transmitted accordingly;

[0080] When the cloud server 10 only receives the ambient sound 2, it is determined that only the earphone case 30 is working currently, and the earphone case 30 pickup content is displayed / transmitted accordingly;

[0081] When the cloud server 10 receives both the ambient sound 1 and the ambient sound 2, it is determined that the earphone case 30 and the earphone are working simultaneously currently. After combining the earphone case 30 pickup content and the earphone pickup content, the combined content is displayed / transmitted.

[0082] Further, the second output port of the audio relay module is connected to the database of the cloud server 10;

[0083] The audio relay module is further configured to: store the target audio stream in the database.

[0084] In this embodiment, in addition to forwarding the target audio stream based on the audio relay module, the database is also connected through the audio relay module to achieve automatic recording of the target audio stream, thereby facilitating the user to reuse the target audio stream.

[0085] In the application, when the external device remotely accessing the cloud server 10 receives the target audio stream, it can also perform automatic storage of the target audio stream for subsequent playback use to ensure that the content of the target audio stream is completely without omission.

[0086] Specifically, the first microphone 21 and the second microphone 31 form a microphone array, and the microphone array is used for:

[0087] Collect key voice signals within the second sound collection range, perform audio encoding on the denoised key voice signals to form a key audio stream, and send the key audio stream to the input port of the audio relay module based on the classic Bluetooth protocol or the low-power Bluetooth protocol. The second sound collection range is a beam range centered on the center of the microphone array with a second set distance as the radius;

[0088] The audio relay module is used for:

[0089] Send the key audio stream to an external device remotely accessing the cloud server 10 based on the classic Bluetooth protocol or the low-power Bluetooth protocol, so that the external device remotely accessing the cloud server 10 plays the key voice signal based on the key audio stream;

[0090] And,

[0091] Decode the key audio stream to obtain the key voice signal, and transmit the key voice signal to the database, so that the database records the key voice signal.

[0092] Wherein, the first set distance and the second set distance may be the same or different, and the present application does not limit this.

[0093] In this example, a microphone array is formed by combining the microphone on the earphone body 20 and the microphone in the earphone case 30 to implement noise reduction processing on the key voice signal, which can reduce the interference of environmental noise and enable the key voice signal to obtain a better audio playback effect.

[0094] In the application, the earphone case 30 has two states: open and closed. When the earphone case 30 is in the open state, the aforementioned storage slot communicates with the external space of the earphone case 30, and the user can complete the action of placing the earphone body 20 in the storage slot of the earphone case 30 or taking out the earphone body 20 from the storage slot; when the earphone case 30 is in the closed state, the aforementioned storage slot does not communicate with the external space of the earphone case 30;

[0095] In this example, when the first microphone 21 and the second microphone 31 form a microphone array, the earphone case 30 is in the open state.

[0096] It should be noted that the key voice signals can also be collected only based on the microphone in the earphone body 20 (i.e., the first microphone 21) or the microphone in the earphone case 30 (i.e., the second microphone 31). In this case, the earphone case 30 can be in the closed state or the open state.

[0097] Exemplarily, in a meeting scenario, by placing the charging case in front of the user who is currently speaking, the speech signal of the speech content of the user who is currently speaking is accurately captured in real time through the microphone array formed by the built-in microphone of the earphone and the built-in microphone of the charging case, and after audio encoding and decoding, it is transmitted to the cloud server 10 through BLE. Other participating users can access the cloud service through the mobile app and can listen to or record the important speech of the user who is currently speaking in real time to ensure the integrity and accuracy of the meeting content.

[0098] In one embodiment, a charging circuit is provided in the earphone case 30. The charging port for connecting the charging cable of the charging circuit is embedded in the outer wall of the earphone case 30, and the discharging terminal of the charging circuit is embedded in the wall of the storage groove. A charging terminal matching the discharging terminal of the charging circuit is provided on the earphone body 20. When the earphone body 20 is stored in the storage groove, the discharging terminal is electrically connected to the charging terminal.

[0099] In one embodiment, an annular connection groove is formed in the outer wall of the earphone case 30, and the charging port of the charging circuit is located in the area enclosed by the connection groove;

[0100] The earphone case 30 further includes a detachable lanyard accessory. The lanyard accessory includes a lanyard body, a length adjustment component, and a first connector. The length adjustment component is sleeved on the lanyard body, and both ends of the lanyard body pass through the length adjustment component and are fixedly connected to the first connector. The first connector is snap-fitted into the connection groove.

[0101] In this embodiment, through the setting of the lanyard accessory, it is convenient for the user to carry the earphone case 30. Especially in the simultaneous interpretation scenario, for users who use the earphone case 30 for cross-language communication, the earphone case 30 can be worn on the chest through the lanyard accessory to avoid various inconveniences brought by holding the earphone case 30, providing convenience for the user to use the earphone case 30.

[0102] Among them, setting the charging port of the charging circuit in the area enclosed by the connection groove is to reduce the proportion of the notch part opened on the outer wall of the earphone case 30, so that the earphone case 30 can maintain a better aesthetic appearance.

[0103] Exemplarily, the first connector can be threadedly connected to the connection groove, can be magnetically attracted to the connection groove, or can be snap-connected to the connection groove.

[0104] In one example, the length adjustment component may be an adjustment belt. A nylon loop is provided on the first side of the adjustment belt, and a nylon hook is provided on the second side of the adjustment belt. The first side and the second side are two opposite sides of the adjustment belt. The adjustment belt is wound to form a limiting area. Both ends of the lanyard body pass through the limiting area and are in tight contact with the second side of the adjustment belt. The nylon hook is engaged with the nylon loop.

[0105] In application, when the user releases the engagement relationship between the nylon hook and the nylon loop by an external force, the length of the part of the lanyard body passing through the limiting area can be adjusted. After the length adjustment is completed, the nylon hook and the nylon loop are engaged again to limit the part of the lanyard body passing through the limiting area and prevent unnecessary sliding of the lanyard body.

[0106] In one embodiment, the earphone case 30 further includes a detachable telescopic bracket. The telescopic bracket includes a base, a support cylinder, a telescopic column, a limit knob, and a second connecting member.

[0107] The support cylinder is provided on the end face of the base. The axis direction of the support cylinder is perpendicular to the end face of the base. The telescopic column is received in the support cylinder, and the telescopic column and the support cylinder are coaxial. A limit screw hole is provided on the outer wall of the support cylinder. The limit knob is threadedly connected to the limit screw hole. The limit knob passes through the limit screw hole and extends into the support cylinder, and is in tight contact with the outer wall of the telescopic column. The second connecting member is fixedly connected to the end of the telescopic column facing away from the base, and the second connecting member is engaged in the connecting groove.

[0108] In this embodiment, based on the cooperation of components such as the base and the support cylinder, the earphone case 30 can be conveniently and stably placed. Among them, based on the sliding of the telescopic column in the support cylinder, the height of the telescopic bracket can be flexibly adjusted, and then the placement height of the earphone case 30 when placed on the telescopic bracket can be adjusted.

[0109] Especially in a meeting scenario, when the earphone case 30 is used as an audio device for meeting speeches, through the setting of the telescopic bracket, without affecting the position movement of the earphone case 30, the earphone case 30 can be stably set on the meeting table. Among them, based on the sliding of the telescopic column in the support cylinder, the placement height and orientation of the earphone case 30 on the meeting table can be flexibly adjusted to adapt to the changing requirements brought about by changes in the meeting environment, changes in speaking users, and changes in user speaking habits in actual applications.

[0110] Further, a bracket power supply circuit is arranged inside the base. The input end of the bracket power supply circuit is electrically connected to a power supply plug on the base. The output end of the bracket power supply circuit is arranged at one end of the telescopic column facing away from the base and is electrically connected to the charging port of the charging circuit. The input end and the output end of the bracket power supply circuit are electrically connected by a connecting wire. The connecting wire is located inside the support cylinder and passes through the telescopic column.

[0111] In this example, through the arrangement of the bracket power supply circuit, while the telescopic bracket places the earphone case 30, the earphone case 30 is synchronously powered to extend the single use duration of the earphone case 30, avoid the situation that the meeting is interrupted due to insufficient power of the earphone case 30, and provide a better user experience for the user.

[0112] In one embodiment, a potentiometer is further arranged inside the earphone case 30. A volume adjustment button is arranged on the outer wall of the earphone case 30. The volume adjustment button is fixedly connected to the moving contact of the potentiometer. The first end of the potentiometer is electrically connected to the output end of the pre-amplification circuit of the second speaker 32. The second end of the potentiometer is electrically connected to the input end of the power amplifier circuit of the second speaker 32.

[0113] In this embodiment, based on the arrangement of the potentiometer and the volume adjustment button, it is convenient for the user to adjust the volume of the sound played by the second speaker 32 of the earphone case 30.

[0114] Exemplarily, multiple volume buttons can be set to correspond to multiple volume levels; or only one volume adjustment button can be set, and the corresponding volume level is determined based on the number of times the user presses the volume adjustment button. For example: it is set that when the user presses the volume adjustment button once, it is the first level, when the user presses the volume adjustment button twice, it is the second level, when the user presses the volume adjustment button three times, it is the third level, and when the user presses the volume adjustment button four times, it returns to the first level, and so on in a cycle (that is, when the number is divisible by 3, it corresponds to the third level, when the number divided by 3 has a remainder of 1, it corresponds to the first level, and when the number divided by 3 has a remainder of 2, it corresponds to the second level).
