1. Field of the Invention
The present invention relates to a Bluetooth earpiece integrated with a Bluetooth headset for automatically switching two-way audio transmissions.
2. Description of Related Art
Bluetooth is a low-cost, low-power and short-distance wireless communication technology extensively used in all kinds of mobile communication devices. The Bluetooth technology wireless transmission function is used in the design of Bluetooth headsets, portable mobile phone watches, and communication devices that can be worn directly on the fingers. The built-in Bluetooth chip of these products not only can perform wireless transmissions, but also can provide user-friendly functions such as logging onto the Internet and sending/receiving E-mail.
Various kinds of Bluetooth headsets are sold in the market, and most are used together with a Bluetooth mobile phone. Users can wear the Bluetooth headset and communicate with others on a standard frequency. Regardless of the time and place, a user can use the wireless transmission function of the Bluetooth technology to receive a phone call with a hands-free effect.

In the meantime, a user can use a microphone 103 to reply and send the audio information 22 to the audio transmission encoder/decoder 106 in the digital signal processor 102. After the reply audio information 22 is sent to the wireless communication module 101 and is encoded by the audio transmission encoder/decoder 106, the wireless communication module 101 sends the replied audio information 22 to a Bluetooth mobile phone 30 at a remote end to complete the two-way audio transmissions. The invention allows a user to receive a phone call at any place and achieves the hands-free effect of the mobile phone.
However, if there is an incoming call, the Bluetooth headset 10 can only provide a user with call reception, and does not allow telephone communication for three or more parties. Therefore, the quality and requirements of telephone communication for our daily life or work will become inferior.
The present invention provides a Bluetooth earpiece with two-way audio transmissions that can be combined with a Bluetooth headset, so as to switch automatically the transmission path of the audio information. The two-way audio transmission is accomplished by a loudspeaker unit and an audio signal capture unit in Bluetooth earpiece.
The Bluetooth earpiece with two-way audio transmissions in accordance with the present invention adopts a base body to contain a Bluetooth headset. The Bluetooth headset is connected to a signal transmitting end by an audio transmission switching unit. The base body is electrically connected to an amplifying unit, a loudspeaker unit and an audio signal capture unit. The amplifying unit is electrically connected to a signal transmitting end of the Bluetooth headset when the Bluetooth headset is fixed with the base body. The audio information from a remote end received by the Bluetooth headset will be sent to the loudspeaker unit in the Bluetooth earpiece to produce sounds through the signal transmitting end of an audio transmission switching unit in the Bluetooth headset. In the meantime, a user can use the audio signal capture unit in the Bluetooth earpiece to receive sounds, and the captured audio information is sent to the Bluetooth headset through the signal transmitting end, so as to complete the two-way sound transmissions.
The earpiece of the present invention is integrated with a Bluetooth headset and amplifies the sound of the audio information received by a remote mobile phone by the loudspeaker unit of the Bluetooth headset, so that users can hear the sound clearly. In the meantime, the present invention uses an audio signal capture unit to send the audio information replies made by several parties to the Bluetooth headset and send such information to a remote mobile phone through the Bluetooth headset, so as to complete the two-way sound transmissions. Therefore, the present invention allows users to have telephone communication for three or more parties, and improve the quality and requirements of telephone communication for daily life and work.
To make it easier for our examiner to understand the innovative features and technical content, we use a preferred embodiment together with the attached drawings for the detailed description of the invention, but it should be pointed out that the attached drawings are provided for reference and description but not for limiting the present invention.
The foregoing aspects and many of the attendant advantages of this invention will be more readily appreciated as the same becomes better understood by reference to the following detailed description, when taken in conjunction with the accompanying drawings, wherein:

If the Bluetooth headset 50 receives audio information from a remote end, the audio transmission switching unit 505 will automatically switch the transmission path of the audio information, and the information is transmitted by the loudspeaker unit and the audio signal capture unit 404 in the Bluetooth earpiece 40, so as to achieve two-way sound transmissions.

Further, after the Bluetooth earpiece 40 with two-way audio transmissions is combined with the Bluetooth headset 50, the audio information of an incoming call received by a remote mobile phone (not labeled in the figure) is amplified by the internal loudspeaker unit 403 of the Bluetooth headset 50 to allow users to hear clearly. At the same time, the Bluetooth earpiece 40 further uses an audio signal capture unit 404 to send the audio information replies made by several parties to the Bluetooth headset 50, and the Bluetooth headset 50 sends the information to a remote mobile phone (not labeled in the figure) to complete a two-way sound transmission. Therefore, users can use the Bluetooth earpiece 40 with two-way audio transmissions to accomplish a telephone communication for three or more parties and electrically charge the Bluetooth headset 40 at the same time. The invention provides many applications to improve the quality and requirement of telephone communications for daily life and work.
Although the present invention has been described with reference to the preferred embodiments thereof, it will be understood that the invention is not limited to the details thereof. Various substitutions and modifications have been suggested in the foregoing description, and others will occur to those of ordinary skill in the art. Therefore, all such substitutions and modifications are intended to be embraced within the scope of the invention as defined in the appended claims.
