Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of voice translation, in particular to a sound control system for voice translation and a sound equipment. BACKGROUND

[0002] With the continuous development of technology, voice interaction technology is increasingly widely used in daily life and business activities, and voice translation function is also increasingly valued by people. Voice translation can break down language barriers and promote communication and exchange between people of different language backgrounds, whether in international business negotiations, travel, or academic exchanges, etc. It has important value and significance. It makes information transmission more efficient and convenient, and promotes cultural exchange and economic cooperation worldwide.

[0003] In existing voice translation scenarios, there are two common ways to achieve voice pickup and translation output. One is to use a single microphone device to collect voice, and then transmit voice data to a translation device for processing through wired or wireless connection. The processed result is played through a separate sound device. The other is to use a smart device integrated with translation function, such as a smart phone with translation software, to directly use the device's own microphone for voice pickup and translation output.

[0004] However, these existing voice translation solutions have obvious defects. The single microphone device is difficult to clearly collect voice information in the surrounding environment due to its limited pickup range, which may lead to missing or inaccurate voice data and affect the quality of translation. Although the smart device integrated with translation function is relatively convenient, its pickup effect and voice output effect are often unsatisfactory in some complex environments, which cannot meet the demand for high-quality voice translation.

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

[0034] Referring to Figure 1 , the first embodiment of the present application discloses an acoustic control system for voice translation. The system framework diagram applied by the system is shown. The voice collected by the microphone of the main microphone mechanism is transmitted wirelessly to the translation APP on the external device such as a mobile phone through the first Bluetooth module, and then the translated voice is transmitted back to the loudspeaker of the main microphone mechanism through the first Bluetooth module for voice output. The voice collected by the microphone of the auxiliary microphone mechanism can be transmitted in two ways based on different protocols. One is based on the Bluetooth BLE protocol adopted, and the second Bluetooth module directly transmits to the translation APP on the external device such as a mobile phone. The other is based on the 2.4G private protocol adopted, and the second Bluetooth module transmits to the first Bluetooth module, and then wirelessly transmits to the translation APP on the external device such as a mobile phone. In this way, the translated voice is transmitted back to the loudspeaker of the main microphone mechanism through the first Bluetooth module for voice output. In addition, the translated voice transmitted back through the first Bluetooth module can also be directly transmitted to the external electronic device through the wired interface, so as to facilitate the user to perform functions such as network telephone, network conference and network live broadcast, thereby increasing the application range.

[0035] Among them, the first embodiment of the present application discloses an acoustic control system for voice translation, which comprises a main microphone module and an auxiliary microphone module. The main microphone module and the auxiliary microphone module establish wireless communication connection through respective communication units, and can jointly complete voice pickup, transmission, translation processing and output, effectively expanding the pickup range and improving the quality of voice translation.

[0036] Referring to Figure 2 , the main microphone module comprises a first pickup unit, a first control unit, a first communication unit and a voice output unit. The first pickup unit selects a high-sensitivity condenser microphone or an electret microphone to clearly and accurately pick up the voice. The first control unit is an integrated circuit board, which plays a role in signal processing and coordinating the work of each unit. The first control unit and the first pickup unit are electrically connected by welding wires to ensure the stability of signal transmission. The first communication unit adopts a Bluetooth BLE communication module. The voice output unit is a small loudspeaker, such as a moving coil loudspeaker, which has good sound quality and low cost.

[0037] The first pickup unit corresponds to a full-directional microphone, which can pick up sound from all directions from 0° to 360°, and convert the first voice in the surrounding environment into an electrical signal after obtaining it, and transmit it to the first control unit. The first control unit performs preliminary processing on the signal, such as amplification, filtering, etc., and then transmits the first voice wirelessly to the external translation device through the first communication unit (which can correspond to the first Bluetooth module described above). After the translation device completes the translation process, the translation result is returned to the voice output unit through the first communication unit, and finally the voice output unit plays the translated voice. Such a combination logic enables the main microphone module to independently complete part of the voice pickup and translation output work.

[0038] Referring to Figure 3 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 signals from the second pickup unit. The second communication unit also uses a Bluetooth BLE communication module to communicate wirelessly with the first communication unit of the main microphone module.

[0039] The second pickup unit can correspond to a heart-shaped directional pickup device. After picking up the second voice with single directivity, the signal is transmitted to the second control unit. After processing the signal, the second control unit sends the second voice directly to the translation device based on different protocols adopted by the second communication unit (which can correspond to the second Bluetooth module described above), or first sends it to the first communication unit of the main microphone module, and then transmits the second voice to the translation device for processing by the first communication unit. The processed translation result is returned to the voice output unit for output. In this way, the secondary microphone module and the main microphone module work together to greatly increase the pickup range of the entire system.

[0040] It is worth mentioning here that in the dual communication mode in the present embodiment, the sound collected by the main microphone module and the secondary microphone module at the same time is directly combined into a single channel for transmission. In order to more efficiently and accurately distinguish and translate the different voices collected by the main microphone module and the secondary microphone module at the same time, the main microphone module is also provided with a bilingual voice mixing unit electrically connected to the first control unit. The bilingual voice mixing unit is a special signal processing chip that can mix the voices collected by the first pickup unit and the second pickup unit at the same time, i.e., add channel tags, to add specific identification information to voice signals from different sources. In this way, after transmission to the translation device, the translation device can accurately split different voices and perform translation according to these identification information.

[0041] In addition, in another embodiment, in order to solve the interference problem of signals in the dual communication mode or the allocation problem of antenna resources, a time slot allocation algorithm is used for time division multiplexing mechanism, and in order to simplify the software algorithm, two antennas far apart are added on the control board, and a right angle design is preferably used to avoid mutual interference. In addition, two channels of Bluetooth and 2.4G are used to stagger the frequency as much as possible to avoid interference.

[0042] Further, in the embodiment, the main microphone module further comprises a contact detection unit and a power management unit, both of which are electrically connected with the first control unit.

[0043] The contact detection unit can be a structure composed of a conductive metal piece and a sensor. When the auxiliary microphone module contacts the main microphone module, the conductive metal piece forms a closed loop, and the sensor senses the conductive signal. The power management unit is an intelligent circuit module that can control the charging of the battery of the auxiliary microphone module and the opening and closing of the working circuit according to the feedback of the contact detection unit. If the contact detection unit senses that the auxiliary microphone module forms a closed loop with the main microphone module, the power management unit will control the battery of the auxiliary microphone module to charge, while closing the working circuit to avoid unnecessary power consumption. If the closed loop is not formed, the power management unit will activate the working circuit and control the second pickup unit to switch the pickup state by monitoring the change of contact impedance, for example, to reduce the pickup sensitivity in a quiet environment to save power, and to increase the pickup sensitivity in a noisy environment.

[0044] The main microphone module further comprises a sleep unit and a level automatic monitoring unit electrically connected with the first control unit. The sleep unit is a timing control module that can control the first pickup unit or the first communication unit to enter a sleep state when there is no voice input for a long time to reduce power consumption. The level automatic 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 the preset value, it controls the first pickup unit to adjust the working state, and controls the first pickup unit to stop picking up sound, so as to shield meaningless environmental sound and also to achieve the function of breaking sentences. In addition, in order to distinguish between speech stop and pause, when the level is lower than the preset value, the first communication unit is controlled to enter a state in which the microphone stops working after a preset time delay. When the level is higher than the preset value, the microphone is instantly activated.

[0045] The main microphone module further comprises an external transmission unit electrically connected with the first control unit. The external transmission unit corresponds to a USB charging interface and / or an audio output interface, which is convenient for connecting to an external power source for charging, and for connecting to external electronic devices for network meetings, cross-border meetings, cross-border live broadcasts, etc., to meet the translation needs.

[0046] The implementation principle of the embodiment is that the sound control system effectively solves the problem of unclear sound pickup caused by the limited sound pickup range of the existing voice translation scheme through the cooperative work of the main microphone module and the auxiliary microphone module. The touch point detection unit can sense whether the auxiliary microphone module and the main microphone module form a closed loop, thereby performing different operations, which can enhance the flexibility and adaptability of the system. The hibernation unit can control the first sound pickup unit or the first communication unit to enter a hibernation state, which can reduce energy consumption. The level automatic monitoring unit controls the working state of the first sound pickup unit or the first communication unit based on whether the volume level is lower than the preset value, to turn on or off the related units as needed. The external transmission unit transmits the translated voice back to the external electronic device, which can expand the output path of the translated voice.

[0047] Referring to Figure 4 and Figure 5 , the second embodiment of the present application discloses a sound device for voice translation, which comprises a main microphone mechanism 10 and an auxiliary microphone mechanism 20. The main microphone mechanism 10 is provided with a through slot 101 for detachably inserting the auxiliary microphone mechanism 20. The main microphone mechanism 10 and the auxiliary microphone mechanism 20 are used in cooperation to meet the sound pickup requirements of different scenes and improve the range and independence of sound pickup.

[0048] Specifically, the main microphone mechanism 10 comprises a first casing assembly 11, a first control board 12, a loudspeaker 13, a first microphone 14 and a first power supply 15. The first control board 12 is electrically connected to the loudspeaker 13, the first microphone 14 and the first power supply 15, and they are all located in the first casing assembly 11.

[0049] The first casing assembly 11 comprises an upper casing 111, a lower casing 112 and an inner casing 113. The upper casing 111 and the lower casing 112 are closed to form a first accommodating slot 102 and a second accommodating slot 103. The first control board 12, the loudspeaker 13, the first microphone 14 and the first power supply 15 are all accommodated in the first accommodating slot 102, and the inner casing 113 is accommodated in the second accommodating slot 103. The inner casing 113 is provided with a through slot 101 for accommodating the auxiliary microphone mechanism 20. The upper casing 111 and the lower casing 112 are generally made of plastic material, which has the characteristics of light weight and low cost. Of course, they can also be made of metal material, such as aluminum alloy, which can provide better strength and heat dissipation performance. The inner casing 113 can also be made of plastic or metal material. Its function is to provide a mounting position for the auxiliary microphone mechanism 20 and also to play a certain isolation and protection role. At the same time, it also serves as a charging compartment of the auxiliary microphone mechanism 20 (see below).

[0050] Referring to Figure 5 , Figure 6 and Figure 7The upper shell 111 and the lower shell 112 are combined together by buckling or screwing or the like. The inner shell 113 is fixed in the second accommodating groove 103 by the first and second plug-in members 1131 and 1132 oppositely arranged on the outer edge. Referring to Figure 8 and Figure 9 The upper shell 111 is provided with the first plug-in groove 1111 for the first plug-in member 1131, and the lower shell 112 is provided with the second plug-in groove 1121 for the second plug-in member 1132. Thus, the inner shell 113 can be stably fixed when the upper shell 111 and the lower shell 112 are combined.

[0051] Referring to Figure 5 and Figure 7 The first control board 12 is located in the first accommodating groove 102 and is fixed on the lower shell 112 by screwing or welding or the like. The first control board 12 is the control core of the entire main microphone mechanism 10 and is usually composed of a printed circuit board and various electronic elements such as chips, resistors, capacitors and the like, which are not limited herein. In addition, the first control board 12 is provided with the first communication module (not shown in the figure) for communicating with external devices. The first communication module adopts a common Bluetooth chip such as CSR8670 and can realize wireless communication with external devices such as mobile phones and computers (communication with the secondary microphone mechanism 20 can be established, see below).

[0052] Referring to Figure 5 and Figure 6 The loudspeaker 13 is located in the first accommodating groove 102 and is electrically connected to the first control board 12. The loudspeaker 13 is used for converting the translated audio electrical signal into voice for playing. In the embodiment, the loudspeaker 13 can adopt a moving-coil loudspeaker, which has the advantages of good sound quality and low cost. Of course, a piezoelectric loudspeaker can also be adopted, which has the characteristics of small size and low power consumption. The loudspeaker 13 is electrically connected to the first control board 12 by welding or plugging or the like.

[0053] Referring to Figure 5 and Figure 6 The first microphone 14 is fixed inside the upper shell 111 and is electrically connected to the first control board 12. Correspondingly, the bracket 114 (see below) is provided with the accommodating groove 1143 penetrating the outside for accommodating the first microphone 14. The first microphone 14 is used for collecting voice, i.e. picking up the user's voice, converting the voice into an electrical signal and transmitting the electrical signal to the first control board 12. The first microphone 14 can adopt a electret condenser microphone, which has the advantages of high sensitivity and wide frequency response. Alternatively, the first microphone 14 can adopt a silicon micro-electro-mechanical system (MEMS) microphone, which has the characteristics of small size and strong anti-interference capability. The first microphone 14 is fixed inside the upper shell 111 by glue or buckling.

[0054] It is worth mentioning here that the main microphone mechanism 10, based on the setting of the first microphone 14, as a full-directional type sound collector, can be more conducive to the collection of human voice at different positions with different sensitivities, and also conducive to the collection of the user's own voice when hanging in front of the chest.

[0055] Referring to Figure 5 and Figure 7 , the first power supply 15 is located in the first accommodating groove 102 and fixed in the lower shell 112, and electrically connected to the first control board 12.

[0061] The second microphone 24 is located in the second shell assembly 22 and is electrically connected to the second control board 23. The second microphone 24 has a similar function to the first microphone 14 and is used to collect user voice. Its type can also be selected as an electret condenser microphone or a MEMS microphone. The second microphone 24 is fixed in the second shell assembly 22 by adhesive or buckle.

[0062] The second power supply 25 is located in the second shell assembly 22 and is electrically connected to the second control board 23 by welding or plugging.

The first magnet 16 and the second magnet 21 adopt at least one of permanent magnets or soft magnetic materials, and the permanent magnets are, for example, neodymium iron boron magnets, which have strong magnetism.

[0066] Further, referring to Figure 5 , Figure 6 and Figure 8 , the first housing assembly 11 further includes a bracket 114 and a filter screen piece 115. The bracket 114 is embedded in the upper housing 111, and the loudspeaker 13 abuts against the first control panel 12 at one end and the bracket 114 at the other end.

[0070] For example, in a quiet indoor environment without environmental noise, the auxiliary microphone mechanism 20 can be not used, and the indoor mode, i.e., the sensitivity is adjusted, is switched through the key assembly 18, so that the sensitivity of the main microphone mechanism 10 is adjusted to be higher, so that the voices of the two parties in conversation are picked up at a farther distance, and such a translation communication is more natural and free. Similarly, in a very noisy environment, if the sensitivity of the main microphone mechanism 10 is too high, other voices or noises in the environment will be picked up, affecting the accuracy of translation. At this time, the outdoor mode can be switched to reduce the sensitivity of the main microphone mechanism 10, and the voices of people close to the main microphone mechanism 10 and the auxiliary microphone mechanism 20 are picked up respectively to ensure the accuracy of translation.
