## Background
FIELD OF THE INVENTION
The present invention relates to a mobile communication peripheral device, and more particularly to a mobile communication peripheral device with dual functions of a badge card and a wireless earphone to be in communication with a mobile phone.
BACKGROUND OF THE INVENTION
In modern society, mobile phones become essential communication devices because they are portable. In some circumstances, however, the mobile phone is not suitable to be hand-held. For example, in the case of driving while using the mobile phone, the likelihood of the traffic accident is increased because only one hand is available for driving. In addition, the user may feel tired and inconvenient in a case of using the hand-held mobile phone for a long time period.
For a purpose of increasing convenience of using mobile phones, many mobile phone accessories such as mobile phone earphone devices, hands-free headsets and the like were developed.
The conventional mobile phone earphone device comprises an earphone and a microphone. The earphone device is plugged in a signal receiving socket of a mobile phone via a wire. When answering a call, the user can hear the caller via the earphone and dialogize with the caller via the microphone.
Although this wired earphone device is applicable when the mobile phone is not suitable to be hand-held, the wire connection between the earphone device and the mobile phone limits the mobility of the user.
In order to expand flexibility of using the hands-free mobile phone and avoid inconvenience of wire linkage, a bluetooth earphone was developed. As known, the bluetooth technology is a wireless transmission technology generally used in localized area, and will not be described in detail herein. The bluetooth earphone has therein a signal processing circuit, which cooperates with a mobile phone having a bluetooth chip to answer calls via the earphone device without the requirement of an electrical cable between the earphone and the mobile phone.
Such a wireless earphone device is not satisfactory because the user usually feels uncomfortable when a weighty or bulky wireless earphone is worn on the user's ear. In particular, it is inconvenient for the user who wears glasses to wear the wireless earphone because the glasses frame may interfere with the wireless earphone.
Accordingly, the above-described prior art method is not a perfect design and has still many disadvantages to be solved.

Preferably, the mobile communication peripheral device of the present invention further comprises a sound recording chip 205, a recording playback key 205A, a recording key 205B and an erasing key 205C.
The method of using the mobile communication peripheral device of the present invention will be described as follows in more details.
During operation, as an identification card for office use is worn, the mobile communication peripheral device is utilized by wearing the connecting wire 400 on the neck thereof. In a case that somebody dial the number of the user's mobile phone, the transceiver 202 may receive the external wireless communication signal from the user's mobile phone and the received signal is transmitted to the signal processing device 201. The wireless communication signal comprises a first audio signal such as the ring tone and the caller's voice. The vibrator 204 is controlled by the signal processing device 201 to generate vibration such that the main body vibrates to notify the incoming call. After the earphone 300 is worn on the ear and the audio transmission control key 700 is pressed down, the communication between the user and the caller begins. During communication, audio of the external call is transmitted to the ear of the user via the earphone 300, and the user can input a second audio signal via the microphone 500. The second audio signal is the replying content of the user. The replying content is processed by the signal processing device 201, transmitted to the user's mobile phone via the transceiver 202, and transmitted to the caller through the user's mobile phone so as to make communication. During communication, the user can control the volume levels by adjusting the volume up control key 800B and the volume down control key 800C.
If the user intends to record the dialogic contents, by pressing the recording key 205B, the user can begin the recording operation. In addition, the recorded contents can be played when the playback key 205A is pressed, and erased when the erasing key 205C is pressed.
The mobile communication peripheral device can use the rechargeable battery 203A to provide electricity. In a case that the power of the rechargeable battery 203A is exhausted, the rechargeable battery 203A can be charged from an external charger (not shown) which is electrically connected to the charging circuit 203B via the charging socket 203D. It is preferred that the external charger may be the charger for use with the user's mobile phone.
The indicator 800D is employed to indicate the operating states of the mobile communication peripheral device. The states of the mobile communication peripheral device indicated by the indicator 800D include for example: (1) a power-on state, (2) a wireless signal searching state (pairing state), (3) a wireless communication on-line state, (4) a communication termination state, (5) a power-off state, and (6) a power deficient state.
The power-on state is entered when the power switch 800A is pressed. In the power-on state, the indicator 800D twinkles green light for 1 second, and the mobile communication peripheral device emits for example a toot sound to notify the power is turned on.
In the wireless signal searching state, the indicator 800D continuously twinkles green light for about 10 seconds, indicating that the mobile communication peripheral device is searching for a compatible wireless communication device. In this embodiment, the compatible wireless communication device is the user's mobile phone. If the mobile communication peripheral device fails to search for the compatible wireless communication device during this time period, the mobile communication peripheral device may be automatically powered off.
In the wireless communication on-line state, the indicator 800D twinkles a blue light every 5 seconds, indicating that the mobile communication peripheral device is linked to the wireless communication device.
In the communication termination state, the indicator 800D twinkles red light for 1 second, indicating that the communication is terminated.
In the power-off state, the indicator 800D twinkles red light for a second, and the mobile communication peripheral device emits a toot sound to notify the power is turned off.
In the power deficient state, the indicator 800D twinkles a red light every 5 seconds, indicating that the power of the battery is deficient.
As know, most wageworkers wear badges when they are on duty. Since the mobile communication peripheral device of the present invention provides the functions of badge and wireless earphone, the convenience of the wireless earphone is imparted thereon but the drawbacks resulted from the wireless earphone are exempted.
In views of the common usage, a conventional badge is hung on a wageworker's neck with a cord when the wageworker is on duty. Since the badge cord can be replaced with a connecting wire and the circuitry for processing wireless communication signals is integrated into the mobile communication peripheral device of the present invention, the user needs not carry any additional accessory to answer calls. Moreover, by using the mobile communication peripheral device of the present invention, the user can receive the wireless communication signals with a wired earphone, but no connecting wire between the mobile phone and the earphone is required. More specially, the user need not wear a weighty and cumbersome wireless earphone device for an extended time period.
It is noted that, however, those skilled in the art will readily observe that numerous modifications and alterations of the connection member may be made while retaining the teachings of the invention. For example, in addition to the bluetooth protocol, other wireless communication protocols are feasible. Further, the twinkling intervals and colors associated with the states of the indicators may be varied. Accordingly, the above disclosure should be limited only by the bounds of the following claims.
While the invention has been described in terms of what is presently considered to be the most practical and preferred embodiments, it is to be understood that the invention needs not be limited to the disclosed embodiment.
