[0025] FIG. 1 is a block diagram showing a terminal device according to a first embodiment.

[0026] In FIG. 1, reference numeral 1A denotes a terminal device implemented as a personal computer in which a data communication application and a VOIP telephone application are installed. This terminal 1A is connected to an IP network.

[0027] The terminal device 1A includes a LAN (Local Area Network) interface (I / F) unit 11, a control unit 12, a storage unit 13 having a memory device and a hard disk drive, a manual volume adjustment 14, a bypass unit 15, switch circuits 16 and 17, an audio amplifier 18 and 19, and a headphone interface (I / F) unit 20. A display unit (LCD) 21 , a keyboard 22 and a mouse 23 are connected to the control unit 12 . The built-in speaker 24 is connected to the audio amplifier 18 , and the built-in microphone 25 is connected to the switch circuit 17 .

[0028] The LAN interface unit 11 performs an interface operation involving an IP network. This means...

[0057] Fig. 5 is a block diagram showing a terminal device according to a second embodiment. The same parts as previously described with reference to FIG. 1 are indicated by the same reference numerals in FIG. 5 and therefore will not be discussed in detail again.

[0058] That is, the terminal device 1B is provided with an audio amplifier 31 including an ALC (Automatic Level Control) function instead of the audio amplifier 18 described above.

[0059] The audio amplifier 31 monitors the signal level of the received voice signal before the received voice signal is input to the built-in speaker 24 . If the signal level of the received voice signal exceeds a predetermined level, the audio amplifier 31 performs gain control so that the signal level becomes equal to or lower than the predetermined level.

[0060] The processing operations in the described configuration will be discussed next.

[0061] FIG. 6 is a frequency characteristic diagram of speaker volume, and FIG. 7 is ...

Abstract

A kind of terminal equipment, comprises: be connected with communication network, be used for transmitting the network interface of the data grouping of the voice grouping that contains voice data; Receive voice and convert it into the microphone of voice signal; Convert voice signal into voice grouping to pass The network interface is transmitted through the communication network, and a converter for converting voice packets received by the network interface into voice signals; a speaker for outputting the voice signals converted by the converter; storing volume values ​​corresponding to a plurality of different operating modes a storage unit; a detection unit that detects the operation mode; and reading a volume value corresponding to the detected operation mode from the storage unit and adjusting a signal level of a voice signal output from the speaker based on the read volume value. Control unit for level control.

Description

[0001] related application [0002] The present disclosure relates to subject matter contained in Japanese Patent Application No. 2004-346563 filed on Nov. 30, 2004, the entire content of which is hereby incorporated by reference. technical field [0003] The present invention relates to a terminal which is used as a VIOP (Voice over Internet Protocol) telephone and to a control method for the terminal, which has a personal computer with, for example, telecommunication capabilities. Background technique [0004] In recent years, a network telephone system (VOIP telephone system) for bidirectionally transmitting and receiving images and voice as packet data through a packet network (VOIP telephone system) has come into widespread use. In the VOIP telephone system, a technique has been proposed in which a personal computer or server is equipped with VOIP telecommunication capability to function as a VOIP telephone set. A software structure in which a VOIP phone application is...
