Abstract
The present invention provides a telephone set with accumulator as energy source, especially a mobile telephone, which includes a device for transmitting a voice-and/or data signal to/from an external equipment (3, 8), and a charge plug (2) having at least two contact terminals fro charging the accumulator. The mobile telephone (1) according to the invention can transmit the voice-and/or data signal by the charge plug (2) to/from an external equipment, such as a portable microphone/loudspeaker device (8). So it needs no other voice-and data communication plugs. Therefore, the mobile phone is smaller, lighter and cheaper.
Description
Since digital network such as being used for mobile communication according to the GSM-standard, mobile phone is also referred to as mobile phone and is promoted exponentially.Such mobile phone provides operating current with a storage battery usually, and storage battery connects the power network charging through charging plug by suitable power-supply device/transformer.
In order to enlarge the ability to communicate of mobile phone, know, mobile phone comprise one be used for to/by external equipment, such as a facsimile equipment or portable computer transferring voice-and the device of data-signal.Know that in addition external microphone/the parts that amplify can be received on the mobile phone.These for example can be intercommunication or so-called earphone on automobile, portable combination earphone/microphone apparatus.Transfer of data to these external equipments will be finished by the appropriate signals plug.Mobile phone must comprise that for this reason a charging plug, Signal plug and one are according to circumstances and fixed aerial plug in a word.
By high frequency-emission/receiving-member of updating battery technology and improvement and dwindle mobile phone constantly being lightened diminishes.Weight and size also are crucial factors for the market effect of mobile phone.
Therefore task of the present invention is, continue to improve telephone set with battery-operated, mobile phone particularly, it comprise one as to/by external equipment transferring voice-and/or the device of data-signal, thereby reduce size, weight and the price of mobile phone.
This task solves by a kind of telephone set of the present invention, this telephone set is a kind of telephone set with battery-operated, mobile phone particularly, it comprise one be used for to/by external equipment transferring voice-and/or the signal transmitting apparatus of data-signal, with one have at least two charging plugs that are used for the contact jaw of charge in batteries, this telephone set especially can with voice-and/or data-signal through charging plug to/transmit by external equipment.Externally can relate to microphone/public address set, computer, facsimile equipment or similar device in the equipment.
This telephone set can comprise a modulator/demodulator 6, with this modulator with the voice that send-or data signal modulation at a link of charging plug, and the signal demodulation that the link through charging plug is received.Preferentially relate to a kind of digital modulation/demodulation device at this.
In telephone set according to the present invention, therefore can both charging plug can be used for to charge in batteries also can be used for to microphone-/public address set transmission of speech signals or to outside data processing equipment transmission of data signals.Therefore removed take up space and expensive be used for voice-/plug of transfer of data.
In addition the present invention advise a kind of microphone that is used for telephone set according to the present invention-/public address set.It comprises a digital modulation/demodulation device that preferentially is used for the modulating/demodulating voice signal equally.
Followingly with accompanying drawing the present invention is described, wherein according to an embodiment
Fig. 1 and a microphone-/ schematic diagram that public address set links to each other according to mobile phone of the present invention; With
The mobile phone that Fig. 2 is shown in Figure 1, but link to each other with a pocket computer.
Mobile phone among Fig. 3 Fig. 1 and microphone-/circuit block diagram of public address set.
Fig. 1 illustrates mobile phone 1, its high-frequency emission/receiving-member, the power supply unit 5 with storage battery, the user interface that comprises keyboard and display and control device corresponding to known mobile phone.This mobile phone comprises a charging plug 2, it both linked to each other also with power supply unit 5 through a modulator/demodulator 6 with to/by the external equipment transferring voice-and/or the transmitting device 4 of data-signal link to each other.
At this, can be transferred to through the voice signal of charging plug 2 and to amplify-microphone apparatus 8.Can also be used as the intercommunication on the automobile for example, or be worn over the portable earphone/device that is called earphone on the account.
Fig. 3 in circuit block diagram, schematically illustrate have companion microphone-/circuit block of the mobile phone 1 of public address set.In speech convertor 10, the high-frequency signal of reception converts ADPCM-signal or opposite to by the 32K Bit Transmission Rate.Signal transmitting apparatus 4 is controlled the transmission of ADPCM-voice signals and data-signal is reached external equipment.In modulator/demodulator 6, the ADPCM-signal is modulated on the power connector end of power supply unit 5, through charging plug 2 with the ADPCM-voice signal be transferred to microphone-/modulator/demodulator of public address set 9 and modulating/demodulating.ADPCM-speech convertor 11 with the ADPCM-conversion of signals so that in loudspeaker or microphone, transmit.Two modulator/demodulator 6,9 are preferential to constitute the digital modulation/demodulation devices, and their allow voice signal transmission (duplex) on two directions simultaneously, then microphone-/microphone and the loudspeaker of public address set 8 can work simultaneously.
Fig. 2 illustrate Fig. 1 according to mobile phone of the present invention, this replace microphone-/public address set can be the pocket computer 3 of receiving charging plug 2 for the transmission data.
If give the charge in batteries of mobile phone, can pull down the data cable jack simply, and insert the charging cable jack that is used for charge in batteries, links to each other with power unit 7.
Therefore, just may both be used for charging plug the charging of storage battery, also be used for to outside device transmission voice signal and data-signal according to mobile phone of the present invention.Thereby reduce the weight and the size of mobile phone.In addition, because produce be used for data-and the modulation circuit of voice signal than other connector cheapness, so also can reduce expense with attached link.
The invention is not restricted to be operated in the mobile phone of a certain high frequency network, can also pack into such as cordless telephone according to the DECT-standard, or with the cable network phone of battery-operated.
