[0002] With the increasing trend of globalization, exchanges between countries and regions are becoming more frequent, but the different languages ​​between countries have become a serious obstacle to communication.

[0003] Currently, everyday translation communication is usually achieved through mobile phone translation apps, but this method cannot achieve the effect of simultaneous interpretation and is very inefficient. Another approach is to use the mobile phone as the core of the translation and then send the translation results to headphones via Bluetooth, which is more complicated to operate; moreover, when the mobile phone is used in other scenarios, it will interfere with the translation function. Summary of the Invention The purpose of this invention is to provide a Bluetooth headset and a translation method, aiming to solve the problem of inconvenience in existing simultaneous translation.

[0004] A Bluetooth headset includes a main body and earphones. The main body has a receiving cavity, and the earphones are disposed in the receiving cavity. The main body also has a host, and the host and earphones are connected via Bluetooth communication. The host includes a sound acquisition module, a translation module, and a control module. The sound acquisition module is used to acquire audio signals, and the control module is used to control the target language output by the translation module. The translation module is used to translate the language information contained in the audio signals acquired by the sound acquisition module into the language information set by the control module. The host is used to send the translated language information to the earphones. The earphones are used to convert the language information into audio signals.

[0005] Preferably, the host further includes a wireless communication module, which is used to send the language information contained in the audio signal collected by the sound acquisition module to the cloud; the wireless communication module is also used to receive the translated language information from the cloud; the host is also used to send the translated language information received by the wireless communication module to the earphone.

[0007] Preferably, the main body is provided with a trigger switch. When the earphone is in contact with the trigger switch, the earphone is in a sleep state; when the earphone is disconnected from the trigger switch, the earphone activates the connection function and automatically connects to the host via Bluetooth.

[0008] Preferably, the earphone has a built-in sound acquisition module, and the earphone is also used to send the audio signal acquired by its built-in sound acquisition module to the translation module.

[0009] This invention also proposes a translation method, comprising the following steps: A. Acquire audio signals and extract language information from the audio signals; B, translate the language information into the specified target language; C, send the translated language information to the playback unit; D, the playback unit converts speech information into audio signals for playback.

[0010] Preferably, in step B, an offline translation package is invoked to translate the language information into the set target language.

[0011] Preferably, step B further includes sending the extracted language information and target language to the cloud and receiving the language information translated into the target language from the cloud.

[0012] Preferably, step B further includes setting the target language as a first language and a second language, translating the language information of the first language into the language information of the second language, and translating the language information of the second language into the language information of the first language; in step C, the playback unit includes a first playback unit and a second playback unit, sending the language information of the first language to the first playback unit and sending the language information of the second language to the second playback unit.

Detailed Implementation

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Please refer to Figure 1 This application relates to a Bluetooth headset capable of simultaneous translation, which achieves simultaneous translation by collecting sound sources and converting the sound sources into the target language.

[0020] The Bluetooth headset includes a main body containing a main unit, earphones, and a battery compartment. The main body has an upper cover 1 and a lower cover 2. In this embodiment, the upper cover 1 and lower cover 2 are fixed together by a threaded connection. In other embodiments, the upper and lower covers can also be connected by a hinge or magnetic connection. The battery compartment is located at the bottom of the lower cover 2 and contains a battery. The battery compartment also has a charging port for charging the battery. The lower cover has a receiving cavity in which the earphones 3 are installed and electrically connected to the charging compartment. The battery compartment is located below the receiving cavity. Preferably, the main unit is installed in the upper cover 1, and the battery compartment charges the main unit wirelessly. The upper cover also has a display module electrically connected to the main unit. The display module includes a display screen 4, which can display the time, date, translated language information, and the target language. The translated language information, in particular, can effectively help users better understand the translated language.

[0021] A trigger switch is provided in the receiving cavity of the lower cover. In this embodiment, the trigger switch uses a pair of elastic contacts; in other embodiments, it can also be a contact piece. When the earphone is placed in the receiving cavity, the earphone contacts the pair of elastic contacts, generating a sleep signal and entering a sleep state. When the earphone is removed, the earphone disconnects from the elastic contacts, generating a working signal that triggers the earphone to automatically connect to the host via Bluetooth. Preferably, the elastic contacts are also electrically connected to the battery compartment. When the earphone's battery level is below 20%, it is charged through these elastic contacts. Similarly, when the host's battery level is below 20%, the battery compartment charges the host via wireless charging.

[0022] The following are the charging experiment data for this application: Experimental environment: continuous use, with the charging case initially fully charged. Experimental data: The charging case can fully charge the main unit approximately 3 times and a single earbud approximately 5 times. The main unit can operate continuously for over 8 hours on a full charge, and the earbuds can operate continuously for over 5 hours on a full charge. Experimental results: The charging case effectively extends the device's battery life, ensuring continuous use of the translation function.

[0023] In a preferred embodiment, the main unit can also be mounted on the lower cover, so that the main unit and the battery compartment can be connected by wires, which also facilitates the main unit's charging control of the battery compartment.

[0024] refer to Figure 1 The top cover 1 is equipped with a hook 5, so that the main body can be hung in front of the chest for easy carrying. At the same time, hanging the column in front of the chest can also more effectively collect audio signals. Preferably, the screen 4 is set on the hook 5.

[0025] Additionally, a speaker is mounted on the main unit and electrically connected to the host. When the headset runs out of power and shuts down, the speaker can take over the headset's function under the control of the control module, transmitting the translated speech.

[0026] Example 1, please refer to Figure 2 The host 10 includes a sound acquisition module 11, a translation module 13, and a control module 12. The sound acquisition module 11 is used to acquire audio information, i.e., to acquire sound sources. The control module 12 is used to control the target language output by the translation module. In other preferred embodiments, the control module 12 is also used to analyze the language of the acquired audio information. The translation module 13 is used to translate the language information contained in the audio information acquired by the sound acquisition module into the language information of the target language set by the control module. The host is used to send the language information translated by the translation module to the headset 3. The headset 3 is used to convert the language information into audio information.

[0027] Figure 2 The corresponding implementation scenario is a one-way translation scenario, such as a conference. Offline translation packages for commonly used languages ​​are pre-downloaded to the host computer. During the conference, the host computer's sound acquisition module captures the conference audio source, removes noise from the audio, and extracts the language information. The translation module then translates this language information into the target language set by the control module. The host computer then sends the translated language information to the headset, which converts the language information into an audio signal for playback. The user wears the host computer and headset, turns on the devices, and ensures they are connected. During communication, the host computer collects the sound source, calls up the offline translation package to perform translation, and plays the result through headphones. Experimental environment: Indoor or outdoor environment without network coverage. Experimental data: In communication using common languages ​​(such as Chinese, English, Japanese, Korean, etc.), the average translation delay is 1-1.5 seconds, and the translation accuracy rate can reach over 92%. Experimental results: The translation headset can still function normally without a network connection, meeting basic offline translation needs.

[0028] Example 2, please refer to Figure 3 The host 10 includes a sound acquisition module 11, a translation module 13, a control module 12, and a wireless communication module 14; compared to Figure 2In the illustrated embodiment, a wireless communication module 14 is added. The wireless communication module 14 is connected to the control module 12 and also wirelessly connected to the cloud 100. The sound acquisition module 11 acquires a sound source, denoises the sound source, extracts the language information, and sends the language information to the cloud 100 via the wireless communication module 14. Simultaneously, the control module 12 also sends the target language information to the cloud 100 via the wireless communication module 14. The cloud 100 translates the language information into the target language and sends it back to the wireless communication module 14. Then, the host 10 sends the translated language information received by the wireless communication module 14 to the earphone 3. The earphone 3 then converts the language information into an audio signal for playback. The wireless communication module is a 4G cellular wireless networking chip. Preferably, the earphone has a built-in sound acquisition module, which is also used to send the audio information acquired by its built-in sound acquisition module to the translation module. Both the earphone 3 and the sound acquisition module 11 can acquire sound sources, enhancing the signal strength of the acquired sound sources and improving translation accuracy.

[0029] The user wears the main unit around their neck, takes out the earphones from the charging case, and puts them on. Turn on the main unit and headphones, and they will automatically connect via Bluetooth. When one party speaks, the headphones and the main unit simultaneously capture the sound source. The host computer performs online translation via a 4G network, transmitting the translated audio signal to the other party's headset for real-time translation and communication.

[0030] Experimental environment: Ordinary indoor environment with a stable 4G network signal. Experimental data: Under normal speaking speed (approximately 120-150 words / minute) communication conditions, the average translation delay is between 0.5 and 1 second, and the translation accuracy rate can reach over 95%. Experimental results: In this scenario, the headphones and the host work well together, enabling smooth real-time translation without the need to connect to a mobile phone, making operation convenient. Example 3, please refer to Figure 4The headset 3 includes a first headset 31 and a second headset 32. For example, in a daily communication scenario, a Chinese person and an American person communicate using the Bluetooth headset of this application. Each person wears one headset. When the Chinese person and the American person speak, the control module analyzes the audio collected by the sound acquisition module to identify whether they are speaking Chinese or English. Based on the analyzed language, the control module sets the first target language to Chinese and the second target language to English. When the Chinese person speaks, the controller analyzes that their language is Chinese, and at this time, the controller switches the target language to the second target language. When the American person speaks, the controller switches the target language back to the first target language. In this way, the controller automatically switches the target language based on the analyzed and identified language, achieving bidirectional translation. This embodiment can solve translation communication in most scenarios.

[0031] In other preferred embodiments, the user can also pre-set a first target language and a second target language through the display module. The host translates according to the pre-set target language and sends the translated language in the first target language to the first earpiece for playback, while sending the language in the second target language to the second earpiece for playback. For example, a Chinese person and a Japanese person can communicate using the Bluetooth earpieces of this application. The user can operate the display module to set the first target language to Chinese and the second target language to Japanese, assigning the first earpiece to the Chinese person and the second earpiece to the Japanese person. When the Chinese person speaks, the host translates the Chinese into Japanese and sends it to the second earpiece for playback; when the Japanese person speaks, the host translates the Japanese into Chinese and sends it to the first earpiece for playback.

[0032] Example 4, please refer to Figure 5 This application also provides a translation method, including the following steps: 101. Acquire audio signals and extract language information from the audio signals; 102. Translate the language information into the specified target language. 103. Send the translated language information to the playback unit; 104. The playback unit converts speech information into audio signals for playback.

[0033] Example 5, please refer to Figure 6 This application also provides a translation method, including the following steps: 201. Acquire audio signals and extract language information from the audio signals; 202. Set the target language as the first language and the second language, and translate the language information in the first language into the language information in the second language, and translate the language information in the second language into the language information in the first language; 203. The playback unit includes a first playback unit and a second playback unit. Language information in the first language is sent to the first playback unit, and language information in the second language is sent to the second playback unit. 204. The playback unit converts speech information into audio signals for playback.
