• Instep210, wireless connection module WCM (e.g., a Bluetooth module) simultaneously establishes a first connection with a right channel unit RCU of a headphone HDP and a second connection with a left channel unit LCU of the headphone HDP during a connection time.
• In one embodiment, a wireless connection module WCM establishes a first connection BL1 between the electronic device ED and the left channel unit LCU and establishes a second connection BL2 between the electronic device ED and the right channel unit RCU.
• In one embodiment, a user can wear the left channel unit LCU on his/her left ear and another user can wear the right channel unit RCU on his/her right ear. In one embodiment, each the left channel unit LCU and the right channel unit RCU includes a connection unit such as Bluetooth module or Wi-Fi module (not illustrated).
• In one embodiment, the wireless connection module WCM establishes the first connection BL1 by Bluetooth or Wi-Fi between the wireless connection module WCM and the sound device SDR and establishes the second connection BL2 by Bluetooth or Wi-Fi between the wireless connection module WCM and the right channel unit RCU in the same time. In other words, the wireless connection module WCM simultaneously establishes the first connection BL2 with the right channel unit RCU of the headphone HDP and the second connection with a left channel unit LCU of the headphone HDP during a connection time.
• Instep220, processor PCR processes a first electrical signal transmitted via the first connection BL1 or a second electrical signal transmitted via the second connection BL2.
• In one embodiment, a microphone (e.g., microphone MIL) of the left channel unit LCU converts a sound into an electrical signal and transmits the electrical signal to the electronic device ED through the connection (e.g., first connection BL1).
• In one embodiment, a microphone MIR of the right channel unit RCU converts a sound into an electrical signal and transmits the electrical signal to the electronic device ED through the second connection BL2.

• Instep230, the processor PCR adjusts the first electrical signal to generate the second electrical signal. The processor PCR is coupled to the wireless connection module WCM (e.g., a Bluetooth module).
• In one embodiment, the processor PCR of the electronic device ED adjusts the electrical signal received from the sound device (e.g., left channel unit LCU) to generate another electrical signal and transmits another electronic signal to another sound device (e.g., right channel unit RCU).
• In one embodiment, the processor PCR of the electronic device ED adjusts the electrical signal received from the right channel unit RCU to another electrical signal and transmits another electronic signal to the another left channel unit LCU.

• In one embodiment, the speaker SPL of another left channel unit LCU converts another electrical signal into another sound.
• The embodiments above are combinable and even can be separately implemented. For example, the wireless connection module WCM establishes a first connection BL1 between the electronic device ED and the left channel unit LCU and establishes a second connection BL2 between the electronic device ED and the right channel unit RCU. The microphone MIL converts a first sound (e.g., the user's voice) into a first electrical signal and the left channel unit LCU transmits the first electrical signal to the electronic device ED through the first connection BL1. The processor PCR adjusts (e.g., changing volume or translating to other language) the first electrical signal received from the left channel unit LCU to generate the second electrical signal and transmits the second electronic signal to the right channel unit RCU. The speaker SPR converts the second electrical signal into a second sound, so that another user can hear the adjusted voice. On another aspect, the microphone MIR converts a third sound (e.g., another user's voice) into a third electrical signal to the electronic device ED through the second connection BL2. The processor PCR adjusts (e.g., changing volume or translating to other language) the third electrical signal received from the right channel unit RCU to generate a fourth electrical signal and transmits the fourth electronic signal to the left channel unit LCU. The speaker SPL converts a fourth electrical signal into a fourth sound, so that the user can hear the adjusted voice.
• FIGS. 3-6 depict schematic diagrams of the scenarios applying the multi-connection method according to one embodiment of present invention. In one embodiment, the processor PCR witches to the whispering mode, the volume up mode or the translation mode, the detail is described as follows.
• In theFIG. 3, when user A is riding a scooter and user B is a passenger, user A can wear the right channel unit RCU and user B can wear the left channel unit LCU. The electronic device ED can be placed in the pocket of user A (or user B). In this way, the processor PCR switches to a whispering mode to adjust the third electrical signal received from right channel unit RCU to generate the fourth electrical signal and transmit the fourth electronic signal to left channel unit LCU. The whispering mode is for performing a short distance conversation. Thus, user A can talk to user B without the louder voice when user A is riding the scooter.
• In theFIG. 4A, user A and user B are in a library. When user A wants to talk to user B in a whisper, user A can wear the right channel unit RCU and user B can wear the left channel unit LCU. The electronic device ED can be placed on the table or any place in the wireless communication area of the electronic device ED. In this way, the processor PCR switches to a whispering mode to adjust the third electrical signal received from right channel unit RCU to generate the fourth electrical signal and transmits the fourth electronic signal to left channel unit LCU. The whispering mode is for performing a short distance conversation. Thus, user A can talk to user B in a whisper.
• In one embodiment, the processor PCR witches to the whispering mode, the volume up mode or the translation mode according to a RSSI (Received Signal Strength Indicator) signal detected by the wireless connection module WCM. If the RSSI signal is larger than a RSSI threshold, the processor PCR switches to the whispering mode. For example, when the electronic device ED placed on the table, the RSSI signal detected by the wireless connection module WCM is larger than a RSSI threshold (e.g., 30 dB), it means that distance between the right channel unit RCU and the left channel unit LCU is larger than a region (but still in the wireless communication area of the electronic device ED, so that the electronic device ED still can detect the RSSI signal), and the processor PCR switches to the whispering mode.
• In theFIG. 4B, the processor PCR detects a degree DG (e.g., angle degree) between the right channel unit RCU and the left channel unit LCU. In a personal use situation, the processor PCR detects the degree DG is smaller than a degree threshold (e.g., 90 degree), and determines that the right channel unit RCU and the left channel unit LCU are in the ears of one user (e.g., shown asFIG. 4B). In two persons use situation, if the degree DG is larger than the degree threshold, the processor PCR determines that the right channel unit RCU and the left channel unit LCU are in different users' ears (e.g., shown asFIG. 4C).
• In theFIG. 5, user A is an American boy only can speak English and user B is a Spanish girl only can speak Spanish. User B can wear the right channel unit RCU and user A can wear the left channel unit LCU. The electronic device ED can be hold by user A (or user B) or placed in any place in the wireless communication area of the electronic device ED. Due to the limitation language, it is hard for user A and user B directly talking to each other, the processor PCR switches to a translation mode to adjust the first electrical signal received from left channel unit LCU to generate the second electrical signal and transmits the second electronic signal to right channel unit RCU. The translation mode is for translating a first language (e.g., “Hello” in English) to a second language (e.g., “Hola” in Spanish). Similarly, through the translation mode performed by the processor PCR, user B can understand the meaning that user A wants to represent when user A is talking in English. Thus, user A and user B can easily have a conversation.
• In theFIG. 6, user A is a boy and user B is user A's (the boy's) grandfather. User A can wear the right channel unit RCU and user B can wear the left channel unit LCU. The electronic device ED can be hold by user A (or user B) or placed in any place in the wireless communication area of the electronic device ED. Due to user B is hard of hearing, the processor PCR switches to a volume up mode to adjust the third electrical signal received from the right channel unit RCU to generate the fourth electrical signal and transmits the fourth electronic signal to left channel unit LCU. The volume up mode is for making the amplifier of the third electrical signal larger. Thus, user B (grandfather) can easily hear the voice talked from the user A (the boy) through the left channel unit LCU.
• The embodiments above mentioned can be combined. For example, inFIG. 6, assuming the user B (grandfather) is hard of hearing and only understand Japanese language, and user A is an American boy only can speak English, the processor PCR switches to a volume up mode and then switches to translation mode to adjust the third electrical signal received from right channel unit RCU to generate the fourth electrical signal and transmits the fourth electronic signal to left channel unit LCU. Thus, user B (grandfather) can hear the louder voice with the translated Japanese language. Thus, user B (grandfather) can easily have a conversation with the user A (the boy) through the left channel unit LCU.
• The method for switching one electrical signal to a whispering mode, a volume up mode or a translation mode can be implemented by know technology, therefore, the detail description is not mentioned.
• In one embodiment, the processor PCR switches to the whispering mode, the volume up mode or the translation mode according to a input configuration. For example, user can setup the configuration by the interface provided by the electronic device ED (e.g., a configuration interface of a smart phone).
• In one embodiment, the processor PCR switches to the whispering mode, the volume up mode or the translation mode according to a RSSI signal detected by the wireless connection module WCM. If the RSSI signal is larger than a RSSI threshold, the processor PCR switches to the whispering mode.
• In one embodiment, the processor PCR adjusts the first electrical signal received from the first sound device to generate the fourth electrical signal according to a USonic signal detected by a USonic module of the left channel unit LCU. The USonic module generates the USonic signal by analyzing the shape of a user's ear canal. The USonic signal is applied to recognize the user, and the sound transfer module adjusts a sound frequency of the first electrical signal corresponding to the user. The technology of USonic is known. Therefore, the detail description of USonic technology is not further mentioned.
• For example, inFIG. 6, when the user A (the boy) wears the right channel unit RCU and gives the left channel unit LCU to user B (the grandfather) can wear, the USonic module in the left channel unit LCU detects the USonic signal by analyzing the shape of a user B's ear canal. The USonic signal is transmitted to the electronic device ED, and the processor PCR compares this received USonic signal with known USonic signal storing a database (not shown) to recognize the user B and obtain the personal data corresponding to user B (e.g, the personal data describes that user B is a Japanese and hard of hearing). The processor PCR adjusts the first electrical signal received from the left channel unit LCU to generate the second electrical signal according to the known personal data corresponding to user B. Thus, the processor PCR automatically switches to a volume up mode and then switches to translation mode to adjust the first electrical signal received from the left channel unit LCU to generate the second electrical signal and transmits the second electronic signal to the right channel unit LCU.
• Based on above, the multi-connection system and the multi-connection system can control the voices outputted by sound devices according to a whispering mode, a volume up mode or a translation mode. And, the multi-connection system and the multi-connection system can flexibly switch to different modes by manual configuration, RSSI detection or Usonic detection. The present disclosure enhances the application of the sound devices by establishing the multi-connection directly between the electronic device and sound devices, without other device. No connection need to be established between sound devices each other. However, the present disclosure is not limited in this regard, another communication technology is within the contemplate scope of the present disclosure.
• Although the present invention has been described in considerable detail with reference to certain embodiments thereof, other embodiments are possible. Therefore, the scope of the appended claims should not be limited to the description of the embodiments contained herein.
