     BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention relates to an associated communication apparatus. In particular, the communication apparatus comprises at least a telephone transmitter, a telephone base, and at least a wireless earphone wherein the apparatus allows multiple incoming calls via the telephone transmitter and/or the wireless earphone simultaneously. 
     2. Description of Related Art 
     Reference is made to  FIG. 1 , which shows a schematic diagram of a traditional telephone set. The telephone set  2  has a communication connecting wire  24  between the dialing host  20  and the transmitter  22 . It uses a transmitting wire  26  to connect to the public switch telephone network (PSTN)  7 . The user presses the key  28  on the host to make a call, links to a remote person via the PSTN  7 , and communicates with the person via the transmitter  22 . 
     However, due to developments in wireless communication technology, the traditional structure of the dialing host  20  connecting with the transmitter  22  via the communication connecting wire  24  has been improved to become a wireless dialing transmitter  2 ′ and a base station  20 ′ both having wireless communicating functions. The wireless dialing transmitter  2 ′ links to the base station  20 ′ by a wireless method, as shown in  FIG. 2 . The base station  20 ′ links to the PSTN  7 . Therefore, users can make calls to one another. 
     Furthermore, Bluetooth® communication is also increasingly being applied to personal portable communication equipment, such as the communication between wireless earphones and cell phones via Bluetooth® protocol. The user can receive a call anywhere, without having to hold on to his or her cell phone. 
     However, when the user communicates via the traditional telephone set  2  with the communication connecting wire  24 , it is inconvenient for the user to communicate by the communication connecting wire  24 . When the user communicates via the wireless dialing transmitter  2 ′ he or she needs to hold the phone close to their ear to hear incoming sounds. If the user is involved in a long call or uses the phone for extended periods, the user&#39;s arm can start to ache. Hence, communication quality is reduced. 
     To sum up, users wish to receive calls anywhere without holding their transmitter and have excellent communication quality in their life. The present invention aims to provide users with a device that meets these wishes.

     When the function key  64  is pressed and then the wireless earphone  8  is detected to be received within the telephone transmitter  11 , the determination module  600  may transmit both of the sound signals of the first phone call and the second phone call to the telephone transmitter  11  only, so that the user of the associated communication apparatus may communicate with the two different phone call terminals via the telephone transmitter  11  at one time. Moreover, when the function key  64  is pressed and the telephone transmitter  11  is detected to be received within the telephone base  6 , with the wireless earphone  8  removed from the telephone transmitter  11 , the determination module  600  may transmit the sound signals of the two phone calls to the wireless earphone  8  only. Thus the user may have a conference call with both of the phone call terminals at the same time without the need to holding a handset and keep the conversation privately. 
     Furthermore, when the function key  64  is pressed, and the detection module  602  detects that the wireless earphone  8  is put back within the telephone transmitter  11  which is also put back within the telephone base  6 , the determination module  600  may transmit the sound signals of the two phone calls to the loud speaker  68  disposed on the telephone base  6 , and receive the user&#39;s voice via the microphone  66  disposed on the telephone base  6 . Therefore, other audience surrounding the associated communication apparatus may also listen to the content of the communications from the two phone call terminals and answer to the phone call terminals publicly. The conference call may be hanged on until the function key  64  is pressed again.

Meanwhile, the communication module  62   a  of the telephone base  6   a  configured to communicating with the wireless earphone  8   a  and the telephone transmitter  11   a  is a DECT module. 
     When two phone calls coming from the PSTN  7 , the telephone controller  60  may transmit the sound signals of the phone calls to the wireless earphone  8   a  and the telephone transmitter  11   a , respectively, in the beginning. The user of the associated communication apparatus may communicate with different phone call terminals separately by disconnecting the wireless earphone  8   a  and the telephone transmitter  11   a  with corresponding connectors  67  and  69 . When the second connector  69  is connected with the second signal transmitting terminal  80  again during sound signal transmission, the detection module  602  may detect the connection between the wireless earphone  8   a  and the telephone base  6   a , and the determination module  600  may determine that the wireless earphone  8   a  is received within the telephone base  6   a . Similarly, when the first connector  67  is connected with the first signal transmitting terminal  114  again during sound signal transmission, the determination module  600  may determine that the telephone transmitter  11   a  is received within the telephone base  6   a  by analyzing the detection result of the detection module  602 . 
     When the determination module  600  determines that either the wireless earphone  8   a  or the telephone transmitter  11   a  is received in the telephone base  6   a  after the function key  64  is pressed, the determination module  600  may transmit sound signals of both lines of phone calls to the telephone transmitter  11   a  or the telephone base  6   a  which is still separated from the telephone base  6   a . Therefore the user of the associated communication apparatus may hold a conference call with the terminals from different phone calls, and communicate with the terminals in a private manner. 
     Furthermore, when the wireless earphone  8   a  and the telephone transmitter  11   a  are both detected to be received in the telephone base  6   a  after the function key  64  is pressed, the determination module  600  may broadcast the sound signals of every phone call in use to the loud speaker  68  of the telephone base  6   a  and receive the user&#39;s voice through the microphone  66  of the telephone base  6   a , instead of transmitting sound signals to or from the wireless earphone  8   a  or telephone transmitter  11   a . Therefore the user of the associated communication apparatus may hold a conference call publicly, so that other users surrounding the telephone base  6   a  may join the conference call as well. 
     Though only one wireless earphone and one telephone transmitter are discussed in the above-mentioned embodiments, the number of the earphone or the transmitter may be plural, as long as the detection module may detect the connection or disconnection between the telephone base, the wireless earphones, and the telephone transmitters. Hence the associated communication apparatus may receive more than two phone calls concurrently and the determination module may transmit the sound signals of each phone call to a corresponding earphone or transmitter. Furthermore, the function key in the above-mentioned embodiments may be disposed at the wireless earphone other than on the telephone base, and the function key configured on the wireless earphone may electronically connect with the earphone controller that communicates with the telephone base via the communication module. Similarly, the function key may be configured on the telephone transmitter and electronically connected with the transmitter controller, so as to transmit the activating signal to the telephone controller through the transmitter controller and the communication module. 
     In another embodiment, when the telephone transmitter links to the telephone base in a wired manner as shown in  FIG. 4 , the first connector and the first signal transmitting terminal may be replaced by a hook switch connected with the telephone controller. The detection module of the telephone controller may detect that the telephone transmitter is received in the telephone base by receiving a signal sent from the hook switch. 
     To sum up, the associated communication apparatus of the present invention allows the user to install the telephone transmitter into the base and install the wireless earphone into the telephone transmitter or the base. Furthermore, the telephone transmitter can be removed from the base and the wireless earphone can be removed from the telephone transmitter. The associated communication apparatus also allows the user to communicate with different phone call terminals via the wireless earphone and the telephone transmitter respectively at the same time, meanwhile, a conference call joined by the plural phone call terminals and the user may be held in a private or a public manner. Therefore, the present invention provides the user with various means for communication so as to avoid the user&#39;s arm from aching when the user has a long call or uses the phone for extended periods, and to increase flexibilities and privacy of telephone communications. The means for communication comprises: 
     1. Utilizing the telephone base for communicating with at least one terminal or holding a conference call publicly; 
     2. Utilizing the telephone transmitter for communicating with the terminal or holding a conference call with multiple phone call terminals privately; 
     3. Utilizing the wireless earphone for communicating with the terminal or holding a conference call with multiple phone call terminals privately.
