The digital signal is then provided to the modulator 202, where the digital signal is modulated according to a special type of transmission plan in use For example, the modulator 202 may be a CDMA modulator, a TDMA modulator, an AMPS modulator or a modulator well known in the art. The digital signal of the modulation is provided to the RF transceiver 204, here It is up-converted to a very high frequency and transmitted through the antenna 206. The transmission to the telephone 100 is received by the antenna 206 and provided to the radio frequency transceiver 204 'where it converts the extreme south frequency to the intermediate frequency. The down-converted signal is provided to the demodulator 208, and the digital type information signal is extracted by the RF transceiver 204. The digital voice information signal is provided to a digital-to-analog (D / A) converter 210. Here, the 'digitized signal is converted into an analog signal suitable for the microphone 212. The amplifier 212 converts the analog electrical signal into sound energy that can be heard by a user. The audio frequency level output from the loudspeaker can only be heard by placing the loudspeaker 212 near the ear. However, there are other types of loudspeakers that can broadcast audio information at a higher level and can be heard even if the bone expander 212 is not placed near the ear. In another embodiment, the telephone set 100 includes two loudspeakers 212, one for conventional telephone use, wherein the audio information is broadcast at a comparable output level, and the other is used for push-to-talk mode operations, where The audio information is broadcast at a fairly high output level.

Description of the invention (6) ㊁Memorize the body 'instruction set to implement the special function of the telephone 100. The processor 214 is controlled by the user's instructions via the input mechanisms 102 and 106, as described above. The information may be provided for viewing by the user via the display 104. ‘During the operation of a conventional telephone, the input mechanisms 102 and 106 are configured as a conventional telephone function. For example, the input mechanism 102 may be a key on the telephone 100 to enter data, such as the corresponding digits of a telephone number. The input mechanism 106 may be a shuttle dial switch to control the volume, or to guide the display 10. 4 Provide t electronic green meter. Information about the electronic directory table is stored in the memory 216. The input mechanisms 102 and 106 send electronic signals to the processor 214, which can tie any number of functional components to achieve special results, such as entering an active number and starting a telephone call. In the push-to-talk mode, the input mechanisms 102 and 106 or both are reconfigured as push-to-talk switches as push-to-talk communication devices. Use = can use a series of inputs from the input mechanism 102 and / or 106 to share with the electronic directory table of the display 104 to select the push-to-talk operation mode. Alternatively, the dedicated push-to-talk button can be pressed to enter the push-to-talk operation mode. When the key is pressed, the telephone 100 is reconfigured as a push-to-talk telephone. , 'After pushing away, the operation panel type is blown—or multiple input mechanism windows are reconfigured as push-to-talk switches. For example, after entering the push-to-talk work panel type, the input mechanism 106 may be preselected as a push-to-talk switch. = Another: In the implementation, the input mechanism 102 can be reconfigured to open the door during the conversation and use the I 1 key on the home phone 100, and use it to type T 'in the knowledge of the phone 100 to be reconstructed.

The processor 214 has pressed the pre-selected key "i" and the "UR table" key. This electrical signal usually lasts until the "1" key is released. While the 1 key is pressed, the processor 214 can make the microphone ⑽ receive (any audio information, transmitted to _ or multiple users. This can be done in many ways in this art Implementation. For example, when the processor 214 detects that a preselected key or a number of keys have been pressed, the signal from the microphone 108 is processed in a similar manner to the conventional telephone mode. In addition, during the T key press, In another embodiment, the processor 214 can use a technique well known in the art to disable the loudspeaker 212. Generally, when f is pushed away, that is, the conversation operation mode, the user's transmission is broadcasted to all network members, including the generation The purpose of transmission. It is best to broadcast the user's transmission back to the user when talking about the conversation. Therefore, when the processor 214 is pushed open, the talk switch is pressed, and the loudspeaker 212 is disabled. Printed When the conversation is released when the push is released, the processor 214 detects the fact that the electrical signal issued by the key or input mechanism 102/106 has been released and changed. In response to the release of this key, the processor 214 prevents audio information from being transmitted to Other network members. The processor 214 can use several well-known methods in this technology to invalidate audio information. For example, the processor 214 can switch between the microphone 108 and A / D 2000 (not shown) Open circuit, thus preventing the processing of audio signals. Alternatively, the processor 214 may change the digitized audio signal at one point in the transmission path to mute or mute only. Alternatively, the processor 214 may be located at the microphone 108 or A / D The gain of one or several of the amplifiers in 200 is reduced to make the audio signal to an unrecognizable level. Generally, the signal from the microphone needs to be amplified by other functional components. This in turn uses one or more amplifiers-10 -This paper size applies the Chinese National Standard (CNS) A4 specification (210 X 297 mm) 580821 A7 ^ ------------- B7 __ 5. The invention description (8) is achieved. In addition to the audio In addition to the inability to transmit information, in another embodiment, the processor 214, for example, the bone expander 110 fails while the talk switch is pressed, and then the printer 110 is moved. The processor 214 can restart the expansion using many well-known technologies.音 器 110。 Figure 3 says The flowchart of the method of the present invention. At step 300, the user selects the push-to-talk operation mode of 100% live machine. As described above, the push-to-run operation mode can be entered by pressing a dedicated key, or Use the displayed electronic directory table to select the push-to-talk operation mode. At step 02, the processor 214 configures one or more input mechanisms as push-to-talk switches. In the exemplary embodiment, the input mechanism 106 includes a shuttle. The switch is reconfigured as a push-to-talk switch. However, other input mechanisms 102 on the telephone can be additionally configured as push-to-talk switches. For example, the 2 " key can be re-configured to push-to-talk Talk switch. As the input mechanism of the push-to-talk switch, it was selected as the push-to-talk switch before loading the program instruction. The program order includes a computer password, which enables the processing unit 214 to control the functions of the telephone 100. Normally, the program is loaded into the memory 216 during the manufacture of the telephone and cannot be accessed by the user. In another example, the program instruction allows the user to select which key to use as the push-to-talk switch. For example, after the user selects the push-to-talk mode, the next press of a key is designated by the processor 214 as the push-to-talk switch. The above description of the preferred embodiment enables those skilled in the art to utilize the present invention. The amendments to these embodiments are also obvious to those skilled in this art. The general principles of the present invention can be applied to other embodiments without using the novel features of the present invention. ^ Factory (21 () χTear " Mod H ------ I7 Pack (Please read the precautions on the back before filling this page) Order ---- Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs
