Description

Technical Field

[0001] This application relates to the field of speech translation, and in particular to an audio device and control system for speech translation. Background Technology

[0002] With the acceleration of globalization, the demand for communication between different languages ​​is growing, and voice translation technology has emerged and is gradually becoming an important tool for solving cross-language communication barriers.

[0003] Currently, voice translation products on the market mainly fall into two categories: translation headsets and portable translation devices. Translation headsets require both parties to wear the same device, which raises issues of social etiquette and psychological distance. Portable translation devices are mostly designed with a single microphone, making it difficult to achieve clear sound pickup over long distances in noisy environments. While Bluetooth speakers offer external playback capabilities, they lack professional translation functions and cannot meet the needs of real-time cross-language communication. In recent years, with the development of wireless communication technology and artificial intelligence translation algorithms, intelligent translation devices combining multi-microphone arrays have become a research hotspot. However, existing solutions still have significant shortcomings in power consumption control, anti-interference capabilities, and user experience, as detailed below: Option 1: Dual-ear translation earphones (such as Google Pixel Buds), which connect to the phone via Bluetooth to achieve real-time translation. Both parties need to wear earphones, which poses hygiene risks and is not suitable for formal occasions. Option 2: Handheld translators (such as iFlytek translators) use a single microphone for directional sound pickup, which requires close-range transmission in noisy environments, interrupting the continuity of communication; Option 3: Smart speakers (such as Amazon Echo) only support use in fixed locations and lack adaptability to mobile scenarios.

[0004] The drawbacks include: limited pickup distance (<1m), inability to be used separately, and insufficient suppression of ambient noise (signal-to-noise ratio <15dB).

[0005] Based on the above solutions, existing equipment cannot simultaneously meet the following requirements: ① Clear sound pickup while maintaining a safe social distance (>1.5m); ② Independent voice acquisition in multi-person scenarios.

[0006] Therefore, how to design an audio device and control system that can maintain a safe social distance between people and enable independent voice acquisition in multi-person scenarios is a technical problem that urgently needs to be solved. Utility Model Content

Detailed Implementation

[0031] The terminology used in the following embodiments of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of this application. As used in the specification and appended claims of this application, the singular expressions “a,” “an,” “the,” “the,” and “this” are intended to include the plural expressions as well, unless the context clearly indicates otherwise. It should also be understood that the term “and / or” as used in this application refers to and includes any or all possible combinations of one or more of the listed items.

[0032] Hereinafter, the terms "first" and "second" are used for descriptive purposes only and should not be construed as implying or suggesting relative importance or implicitly indicating the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature, and in the description of the embodiments of this application, unless otherwise stated, "multiple" means two or more.

[0033] The technical solutions of the embodiments of this application are described in detail below with reference to the accompanying drawings.

[0034] First Embodiment See Figure 1 and Figure 2 The first embodiment of this application discloses an audio device for voice translation, including a main microphone mechanism 10 and a secondary microphone mechanism 20. The secondary microphone mechanism 20 is detachably installed on the main microphone mechanism 10. The main microphone mechanism 10 and the secondary microphone mechanism 20 are used together to meet the sound pickup needs of different scenarios and improve the range and independence of sound pickup.

[0035] Specifically, the main microphone mechanism 10 includes a first housing assembly 11, a first control board 12, a speaker 13, a first microphone 14, and a first power supply unit 15, wherein the first control board 12 is electrically connected to the speaker 13, the first microphone 14, and the first power supply unit 15, and all are located within the first housing assembly 11.

[0036] The main microphone mechanism 10 is provided with a through slot 1131 for the detachable insertion of the secondary microphone mechanism 20. The first housing assembly 11 includes an upper housing 111, a lower housing 112, and an inner housing 113. The upper housing 111 and the lower housing 112 are joined to form a first receiving cavity 101. The inner housing 113 passes through the upper housing 111 and the lower housing 112, and has a through slot for accommodating the secondary microphone mechanism 20. In use, the secondary microphone mechanism 20 can be directly inserted into the inner housing 113. The first control board 12, the speaker 13, the first microphone 14, and the first power supply unit 15 are all housed in the first receiving cavity 101. The upper housing 111 and the lower housing 112 are generally made of plastic, which is lightweight and low-cost. Of course, they can also be made of metal, such as aluminum alloy, which provides better strength and heat dissipation. The inner housing 113 can also be made of plastic or metal. Its function is to provide a mounting position for the secondary microphone mechanism 20 and to provide a certain degree of isolation and protection. It also serves as a charging compartment for the secondary microphone mechanism 20 (see below).

[0037] See Figure 2 , Figure 3 and Figure 4 The upper housing 111 and the lower housing 112 are joined together by snaps or screws. The inner housing 113 is fixed in the first receiving cavity 101 by a first connector 1132 and a second connector 1133 disposed opposite each other on its outer edge. See also Figure 5 and Figure 6The upper housing 111 is provided with a first insertion slot 1111 for the first insertion member 1132 to be inserted, and the lower housing 112 is provided with a second insertion slot 1121 for the second insertion member 1133 to be inserted, so that the inner housing 113 can be stably fixed when the upper housing 111 and the lower housing 112 are engaged.

[0038] See Figure 2 and Figure 4 The first control board 12 is located in the first accommodating cavity 101 and is fixed to the lower housing 112 by screws or welding (in another embodiment, it can also be fixed to the upper housing 111). The first control board 12 is the control core of the entire main microphone mechanism 10. It is usually composed of a printed circuit board and various electronic components, such as chips, resistors, capacitors, etc., which are not limited here. In addition, a first communication module (not shown in the figure) for communicating with external devices is provided on the first control board 12. The first communication module uses a common Bluetooth chip, such as CSR8670, which can realize wireless communication with external devices such as mobile phones and computers (it can establish communication with the secondary microphone mechanism 20, see the following description).

[0039] See Figure 2 and Figure 3 The speaker 13 is located in the first accommodating cavity 101 and electrically connected to the first control board 12. The speaker 13 is used to convert the translated audio electrical signal into speech for playback. In this embodiment, the speaker 13 can be a moving-coil speaker, which has the advantages of good sound quality and low cost. Alternatively, a piezoelectric speaker can be used, which has the characteristics of small size and low power consumption. The speaker 13 is electrically connected to the first control board 12 by means of soldering or plugging.

[0040] See Figure 2 and Figure 3 The first microphone 14 is fixed inside the upper housing 111 (in another embodiment, it can also be fixed inside the lower housing 112), and is electrically connected to the first control board 12. A corresponding receiving groove 1143 penetrating the outside is provided on the bracket 114 (see later description) to accommodate the first microphone 14. The first microphone 14 is used to collect voice, i.e., to pick up the user's voice, converting the voice into an electrical signal and transmitting it to the first control board 12. The first microphone 14 can be an electret condenser microphone, which has the advantages of high sensitivity and wide frequency response, or it can be a silicon microelectromechanical system (MEMS) microphone, which has the characteristics of small size and strong anti-interference ability. The first microphone 14 is fixed to the inside of the upper housing 111 by adhesive or clips. It is worth mentioning that the main microphone mechanism 10, based on the first microphone 14, acts as an omnidirectional pickup to pick up surrounding voice, which is more conducive to picking up human voices from different positions at different sensitivities. When suspended in front of the chest, it is also beneficial for picking up the user's own voice.

[0041] See Figure 2 and Figure 4 The first power supply component 15 is located in the first accommodating cavity 101 and fixed within the lower housing 112, and is electrically connected to the first control board 12. The first power supply component 15 provides power to the entire main microphone mechanism 10, and generally uses a lithium battery, which has the advantages of high energy density and multiple charging cycles. In another embodiment, dry cell batteries can also be used for easy replacement. The first power supply component 15 is electrically connected to the first control board 12 by welding or plugging / unplugging to supply power to it.

[0042] The main microphone mechanism 10 is composed of these components. The first control board 12 coordinates the work of each component, the first microphone 14 collects voice, the speaker 13 plays the translated voice, the first power supply 15 provides power, and the first communication module realizes communication with external devices, sends the collected voice to the electronic device for translation, and sends the translated audio back to the speaker 13 for playback. In this way, the main microphone mechanism 10 can complete functions such as voice collection, translation and playback.

[0043] For details, see Figure 6 The secondary microphone mechanism 20 includes a second housing assembly 22, a second control board 23, a second microphone 24, a second power supply unit 25, and a contact 26. The second control board 23 is electrically connected to the second microphone 24, the second power supply unit 25, and the contact 26, and is located in the second housing assembly 22. One end of the contact 26 is electrically connected to the second control board 23, and the other end is exposed outside the second housing assembly 22 for electrical connection to the first control board 12. Correspondingly, a connector 17 is electrically connected to the first control board 12. The connector 17 penetrates the inner housing 113 and abuts against the contact 26 when the secondary microphone mechanism 20 is placed inside the inner housing 113, thereby realizing the circuit connection between the first control board 12 and the second control board 23, thereby enabling the first power supply unit 15 to supply power to the second power supply unit 25, and simultaneously triggering the control function to turn off the working state of the secondary microphone mechanism 20.

[0044] See also Figure 2 The second housing assembly 22 is used to pass through the through slot 1131. The second housing assembly 22 is generally also made of plastic to ensure portability. The shape and size of the second housing assembly 22 are adapted to the through slot 1131 for easy insertion and removal.

[0045] The second control board 23 is located within the second housing assembly 22, and a second communication module (not shown in the figure) is mounted on the second control board 23 to communicate with the first communication module. The second control board 23 also consists of a printed circuit board and electronic components, and is fixed to the second housing assembly 22 by screws or soldering. The second communication module, like the first communication module, uses a common Bluetooth chip, such as the CSR8670, to achieve pairing and communication between the two.

[0046] During the operation of the secondary microphone mechanism 20, the second controller transmits the audio collected by the second microphone 24 to the main microphone mechanism 10 through communication between the second communication module and the first communication module. Then, the audio is transmitted to the external translation device through the first communication module under the control of the first control board 12. After translation, the audio is transmitted back to the speaker 13 through the first communication module for playback.

[0047] The second microphone 24 is located in the second housing assembly 22 and is electrically connected to the second control board 23. The function of the second microphone 24 is similar to that of the first microphone 14, used to collect user voice. It can also be an electret condenser microphone or a MEMS microphone. The second microphone 24 is fixed in the second housing assembly 22 by adhesive or clips.

[0048] The second power supply unit 25 is located in the second housing assembly 22 and is electrically connected to the second control board 23 by means of welding or plugging. The second power supply unit 25 uses a rechargeable lithium battery, and together with the contact member 26, it can continuously provide power to the secondary microphone mechanism 20.

[0049] It should be noted that the secondary microphone mechanism 20 is generally used in noisy environments for specific individuals to speak, and sometimes it may be held by another user, where there may be a certain social distance. In this embodiment, the secondary microphone mechanism 20 is a unidirectional pickup based on the second microphone 24, which is more conducive to suppressing environmental noise.

[0050] These components of the secondary microphone mechanism 20 are combined together. The second control board 23 controls the second microphone 24 to collect voice, the second power supply unit 25 provides power, and it communicates with the main microphone mechanism 10 through the second communication module. It can also achieve electrical conduction with the main microphone mechanism 10, further enhancing the sound pickup capability and flexibility of the entire audio equipment.

[0051] Furthermore, to increase the stability of the main microphone mechanism 10 and the secondary microphone mechanism 20 assembly and facilitate disassembly, a first magnet 16 is provided in the main microphone mechanism 10, located in the first accommodating cavity 101, with one end abutting against the first control board 12 and the other end abutting against the outside of the inner housing 113. Correspondingly, a second magnet 21 is provided in the secondary microphone mechanism 20. The secondary microphone mechanism 20 is fixed in the through slot 1131 by the mutual magnetic attraction of the first magnet 16 and the second magnet 21, which also ensures the stable contact of the contact member 26 and the plug member 17, realizing circuit conduction. The first magnet 16 and the second magnet 21 are permanent magnets, such as neodymium iron boron magnets, which have strong magnetism.

[0052] Further, see Figure 2 , Figure 3 and Figure 5The first housing assembly 11 also includes a bracket 114 and a filter 115. The bracket 114 is embedded in the upper housing 111. One end of the speaker 13 abuts against the first control plate 12, and the other end abuts against the bracket 114. An embedding groove 1112 is provided in the upper housing 111 corresponding to the bracket 114, and a fastening element 1113 is provided on the inner wall of the embedding groove 1112. A fastening groove 1141 is provided on the outer edge of the bracket 114. During assembly, the bracket 114 passes through the embedding groove 1112 from the inside of the upper housing 111. Through the fastening of the fastening element 1113 and the fastening groove 1141, the bracket 114 can be firmly fixed on the upper housing 111 to support the speaker 13 and ensure the stable installation of the speaker 13. The bracket 114 can be made of plastic or metal and manufactured by injection molding or stamping. The receiving slot 1143 for accommodating the first microphone 14 extends through the embedding slot 1112, allowing for clearer acquisition of surrounding speech.

[0053] The filter element 115 has a third connector 1151 on its edge, and the bracket 114 has a third connector groove 1142 for the third connector 1151 to be inserted into. The filter element 115 is inserted into the third connector groove 1142 of the bracket 114 from the outside of the upper housing 111 via the third connector 1151 to cover and protect the speaker 13. At the same time, the structure of the filter element 115 and the bracket 114 facilitates the installation and removal of the filter element 115.

[0054] Furthermore, multiple engaging members 1122, such as four, are provided inside the lower housing 112. Figure 6 As shown in the diagram, multiple engaging components 1122 are used to enclose and fix the first power supply component 15. The engaging components 1122 are generally made of plastic and manufactured by injection molding. The multiple engaging components 1122, arranged together, securely fix the first power supply component 15 within the lower housing 112, while simultaneously improving the stability of the internal structure.

[0055] Further, see Figure 3 and Figure 5 The main microphone mechanism 10 also includes a button assembly 18, electrically connected to the first control board 12. Correspondingly, first slots 102 are provided on the upper housing 111 and lower housing 112 to accommodate the button assembly 18. The button assembly 18 facilitates user operation of the main microphone mechanism 10, such as turning it on, off, or switching modes. The button assembly 18 can be a mechanical button or a touch button, electrically connected to the first control board 12 via soldering or plugging. The size and shape of the first slot 102 are adapted to the button assembly 18.

[0056] For example, in a quiet indoor environment without ambient noise, the secondary microphone mechanism 20 can be omitted. The indoor mode can be switched using the button assembly 18, which adjusts the sensitivity to increase the sensitivity of the main microphone mechanism 10, allowing it to pick up the voices of both parties from a greater distance. This makes the translation and communication more natural and free. Similarly, in a very noisy environment, if the sensitivity of the main microphone mechanism 10 is too high, it may pick up other voices or background noise, affecting the accuracy of the translation. In this case, the outdoor mode can be switched to reduce the sensitivity of the main microphone mechanism 10, allowing both the main microphone mechanism 10 and the secondary microphone mechanism 20 to pick up the voices of people closer together, ensuring the accuracy of the translation.

[0057] Furthermore, see Figure 1 and Figure 3 The main microphone mechanism 10 also includes at least one interface component 19, electrically connected to the first control board 12. Correspondingly, second slots 103 are provided on the upper housing 111 and lower housing 112. The main microphone mechanism 10 connects to an external power source and / or electronic devices via the second slots 103 and the interface component 19. The interface component 19 can be a USB interface, Type-C interface, etc., facilitating connection to an external power source for charging and connection to external electronic devices for web conferencing, cross-border meetings, cross-border live streaming, etc., meeting translation needs.

[0058] Additionally, see Figure 2 and Figure 6 The audio equipment also includes a hanging bracket 30 and a crossbar 40. One end of the crossbar 40 passes through the hanging bracket 30 and is housed in a second receiving cavity 104 formed by the mating of the upper housing 111 and the lower housing 112. The other end of the hanging bracket 30 protrudes from the first housing assembly 11. The hanging bracket 30 allows users to easily carry and hang the audio equipment, and the cooperation between the crossbar 40 and the second receiving cavity 104 ensures the stable installation of the hanging bracket 30.

[0059] The implementation principle of this embodiment is as follows: The audio device uses a combination of a main microphone mechanism 10 and a secondary microphone mechanism 20. The main microphone mechanism 10 is responsible for the main voice acquisition and playback functions, while the secondary microphone mechanism 20 can be detachably installed on the main microphone mechanism 10, and its pickup position can be adjusted according to actual needs. The first control board 12 and the second control board 23 work in coordination, and the first communication module and the second communication module realize data transmission. The reasonable layout and connection method of each component enable the audio device to clearly pick up sound while maintaining a safe social distance, and achieve independent voice acquisition in multi-person scenarios. Compared with existing technologies, it improves the pickup distance, enhances the ability to suppress environmental noise, meets the user's needs in different scenarios, and solves the problems of limited pickup distance, inability to be used separately, and insufficient environmental noise suppression in existing devices, thereby improving the user experience.

[0060] Second Embodiment See Figure 7 This is a schematic diagram of the system framework used in the audio equipment control system for voice translation disclosed in the second embodiment of this application. Voice is collected by the main microphone and wirelessly transmitted via a first Bluetooth module to an external device, such as a translation app on a mobile phone. The translated voice is then transmitted back to the speaker of the main microphone via the first Bluetooth module for output. Voice collected by the secondary microphone can be transmitted in two ways based on different protocols: one is based on the Bluetooth BLE protocol, where the second Bluetooth module directly transmits the voice to an external device, such as a translation app on a mobile phone; the other is based on a 2.4G proprietary protocol, where the second Bluetooth module transmits the voice to the first Bluetooth module, and then wirelessly transmits it to an external device, such as a translation app on a mobile phone. The translated voice is then uniformly transmitted back to the speaker of the main microphone via the first Bluetooth module for output. Alternatively, the translated voice transmitted back via the first Bluetooth module can also be directly transmitted to an external electronic device via a wired interface to facilitate functions such as VoIP, web conferencing, and live webcasting, thereby expanding the applicability.

[0061] The second embodiment of this application discloses an audio equipment control system for speech translation, which includes a main microphone module and a secondary microphone module. The main microphone module and the secondary microphone module establish a wireless communication connection through their respective communication units, and can jointly complete the pickup, transmission, translation processing and output of speech, effectively expanding the pickup range and improving the quality of speech translation.

[0062] See Figure 8 The main microphone module includes a first pickup unit, a first control unit, a first communication unit, and a voice output unit. The first pickup unit uses a high-sensitivity condenser or electret microphone to clearly and accurately pick up speech. The first control unit is an integrated circuit board that processes signals and coordinates the operation of each unit. The first control unit and the first pickup unit are electrically connected via soldered wires to ensure stable signal transmission. The first communication unit uses a Bluetooth BLE communication module. The voice output unit is a small speaker, such as a dynamic speaker, which offers good sound quality at a lower cost.

[0063] The first pickup unit is an omnidirectional microphone capable of picking up sound from all directions from 0° to 360°. After obtaining the initial speech from the surrounding environment, it converts it into an electrical signal and transmits it to the first control unit. The first control unit performs preliminary signal processing, such as amplification and filtering, and then wirelessly transmits the initial speech to an external translation device via the first communication unit (which may correspond to the aforementioned first Bluetooth module). After completing the translation process, the translation device sends the translation result back to the voice output unit via the first communication unit, and finally, the voice output unit plays the translated speech. This combination logic enables the main microphone module to independently complete a portion of the speech pickup and translation output work.

[0064] See Figure 9 The secondary microphone module includes a second pickup unit, a second control unit, and a second communication unit. The second pickup unit also uses a condenser microphone or an electret microphone. The second control unit is an integrated circuit board responsible for processing the signals transmitted from the second pickup unit. The second communication unit also uses a Bluetooth BLE communication module to enable wireless communication with the first communication unit of the main microphone module.

[0065] The second pickup unit can be a cardioid microphone, unidirectionally picking up the second voice signal and transmitting it to the second control unit. The second control unit processes the signal and, through the second communication unit (which can correspond to the aforementioned second Bluetooth module), sends the second voice signal directly to the translation device based on the chosen protocol, or first sends it to the first communication unit of the main microphone module, which then transmits it to the translation device for processing. The processed translation result is then sent back to the voice output unit via the first communication unit for output. In this way, the secondary microphone module and the main microphone module work together, significantly increasing the overall system's pickup range.

[0066] It is worth mentioning that in this embodiment, in dual communication mode, the sounds collected simultaneously by the main microphone module and the secondary microphone module are directly merged into a mono for transmission. In order to more efficiently and accurately distinguish and translate the different voices collected simultaneously by the main microphone module and the secondary microphone module, the main microphone module is also equipped with a dual voice mixing unit electrically connected to the first control unit. The dual voice mixing unit is a dedicated signal processing chip that can tag and mix the voices collected simultaneously by the first and second microphone units, that is, add channel tags to add specific identification information to the voice signals from different sources. In this way, after being transmitted to the translation device, the translation device can accurately separate the different voices and translate them according to these identification information.

[0067] In another embodiment, to address signal interference or antenna resource allocation issues in dual communication modes, a time-slot allocation algorithm is employed for time-division multiplexing. To simplify the software algorithm, two widely spaced antennas are added to the control board, avoiding parallel designs and preferably employing a right-angle design to minimize mutual interference. Furthermore, both Bluetooth and 2.4G channels are used, with frequencies staggered as much as possible to prevent interference.

[0068] See Figure 8 The main microphone module also includes a contact detection unit and a power management unit, both of which are electrically connected to the first control unit.

[0069] The contact detection unit can be a structure composed of conductive metal parts and sensors. When the secondary microphone module contacts the primary microphone module, the conductive metal piece forms a closed loop, and the sensor detects the conduction signal. The power management unit is an intelligent circuit module that controls the charging of the secondary microphone module's battery and the opening and closing of its operating circuit based on feedback from the contact detection unit. If the contact detection unit detects that the secondary microphone module and the primary microphone module have formed a closed loop, the power management unit will control the secondary microphone module's battery to charge while simultaneously shutting down the operating circuit to avoid unnecessary power consumption. If no closed loop is formed, the power management unit will activate the operating circuit and control the second pickup unit to switch pickup states by monitoring changes in contact impedance. For example, it can reduce pickup sensitivity in quiet environments to save power and increase pickup sensitivity in noisy environments.

[0070] The main microphone module also includes a sleep unit and an automatic level monitoring unit, both electrically connected to the first control unit. The sleep unit is a timing control module that controls the first pickup unit or the first communication unit to enter sleep mode when the system has been without voice input for an extended period, thus reducing power consumption. The automatic level monitoring unit is a voltage comparison circuit that monitors the volume level of the voice signal in real time. When the volume level is lower than a preset value, it controls the first pickup unit to adjust its operating state, preventing the microphone from picking up sound or stopping it altogether. This effectively blocks out meaningless ambient noise and also serves as a pause in speech. Furthermore, to differentiate between pauses and stops in speech, when the level is lower than a preset value, it also controls the first communication unit to enter a microphone-off state after a preset delay. When the level is higher than a preset value, the microphone instantly starts working.

[0071] The main microphone module also includes an external transmission unit electrically connected to the first control unit. This external transmission unit corresponds to a USB charging port and / or an audio output port, facilitating connection to an external power source for charging and connecting external electronic devices for web conferencing, cross-border meetings, cross-border live streaming, etc., to meet translation needs.

[0072] The implementation principle of this embodiment is as follows: This audio control system effectively solves the problem of unclear sound pickup caused by the limited pickup range of existing speech translation solutions through the coordinated work of the main microphone module and the secondary microphone module. By setting a contact detection unit, it can sense whether the secondary microphone module and the main microphone module form a closed loop, thereby executing different operations and enhancing the system's flexibility and adaptability. By setting a sleep unit, the first pickup unit or the first communication unit can be controlled to enter a sleep state, reducing energy consumption. By setting an automatic level monitoring unit, the operating state of the first pickup unit or the first communication unit is controlled based on whether the volume level is lower than a preset value, allowing the relevant units to be turned on or off as needed. The translated speech is transmitted back to external electronic devices through an external transmission unit, expanding the output channels of the translated speech.

[0073] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application.
