[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a telephone communication device having a handset.
[0002]
[Prior art]
A conventional technique will be described with reference to FIG. FIG. 3 is a schematic block diagram of a conventional telephone communication device. In the figure, a telephone communication device body 20 includes a network unit 2 that interfaces with a communication network 7, a control unit 4 that controls the network unit 2 based on an output from the detection unit 3, a hook switch 21 that is switched by a handset 5, and the like. It is composed of
Since the handset 5 is picked up during a call, it is off-hook by the hook switch 21, and at the end of the call, the handset 5 is lowered and the hook switch 21 goes on-hook. As described above, the hook detection is performed by the hook switch 21 instead of the acoustic signal from the handset 5.
[0003]
[Problems to be solved by the invention]
Conventionally, however, since a personal computer or the like has no hook switch just by connecting the handset to the audio output / input, there is a problem that the handset must be operated on the screen as well as placing the handset in the end call operation.
[0004]
The present invention has been made in view of the above points, and provides a telephone communication device that can complete a call-ending operation by placing a handset even in a telephone communication device in which a hook switch cannot be provided. With the goal.
[0005]
[Means for Solving the Problems]
A function to monitor the input from the handset with a digital signal processor (DSP) or tone detector is provided, and the state of the handset is analyzed. On-hook / off-hook is detected instead of the hook switch by analyzing the state of the handset from the input from the handset.
[0006]

And a control unit 4 that performs hook control on the network unit 2 based on an output from the detection unit 3, and detects a shock sound when the detection unit 3 places the handset 5. It is characterized by having a hook detection function.
[0007]
The telephone communication device of the present invention includes a network unit 2 that interfaces with the communication network 7 and a detection unit that detects a specific sound by monitoring input from the handset 5 in a telephone communication device having a handset. 3 and a control unit 4 that performs hook control on the network unit 2 based on the output from the detection unit 3, and the detection unit 3 is generated from the handset 5 when placed on a desk without being used. It has a feature that it has a hook detection function by detecting howling .
[0009]
In the telephone communication device of the present invention, in the telephone communication device having a handset, the line control circuit 12 that controls the line and the specific frequency transmitted from the handset stand 17 by monitoring the input from the handset 5 are monitored. A tone detector 13 to be detected and an MPU 14 for performing hook control on the line control circuit 12 based on the output from the tone detector 13 and accessing the personal computer main body 10 are provided. The tone detector 13 is connected to the handset base 17. It is characterized in that it has a hook detection function by detecting that the handset 5 is receiving a specific frequency .
[0010]
【Example】
Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a schematic block diagram of a telephone communication device in an embodiment of the present invention. In the figure, the telephone communication device main body 1 is composed of a network unit 2, a detection unit 3, a control unit 4 and the like for detecting a specific sound by monitoring input from the handset 5. The detection unit 3 includes a DSP, a tone detector, and the like. In addition, what attached | subjected the same code | symbol as FIG. 3 has shown the same element, respectively.
[0011]
On-hook / off-hook is detected by providing a detection unit 3 that monitors the input from the handset 5 via the network unit 2 and detects a specific sound. The control unit 4 performs hook control on the network unit 2 by detecting the on-hook / off-hook hook.
As an example 1, an impact sound when the handset 5 is placed is detected by the detection unit 3 to be on-hook at the end of the call, and the control unit 4 performs hook control on the network unit 2. The network unit 2 has an interface with the communication network 7.
[0012]
As an example 2, when the handset 5 is left unused and placed on a desk or the like, it is designed to perform howling, and on-hook / off-hook is detected by the presence or absence of howling. Hook control is performed on the unit 2.
[0013]
As an example 3, FIG. 2 shows a schematic block diagram of a telephone communication device in another embodiment of the present invention. This is an example in which an extension board for connecting a line and a handset is inserted into a personal computer. In the figure, 10 is a PC main body, 11 is a business horn board of an expansion board as a telephone communication device, 12 is a line control circuit for controlling a line, 13 is a tone detector for detecting a specific sound, and 14 is from a tone detector 13. MPU (microprocessor) for performing hook control to the line control circuit 12 based on the output of the PC and accessing the personal computer 10, 15 and 16 are amplifiers, and 17 is a table for the handset 5. A speaker 18 that outputs an external specific frequency is provided.
[0014]
The state of whether the handset 5 is on the pedestal 17 (on-hook or off-hook) is distinguished depending on whether a specific frequency can be detected. The state of the hook is detected by monitoring a specific signal or the like output from the pedestal 17 of the handset 5. The MPU 14 controls the line control circuit 12 based on the hook detection. The line control circuit 12 interfaces with the communication network 7.
[0015]
The extension board 11 to which the handset 5 is connected is provided with a tone detector 13 for detecting a specific frequency sent from the speaker 18 of the handset stand 17 . The expansion board 11 notifies the communication application of on-hook when detecting a specific frequency from the speaker 18 and off-hook when no specific frequency is detected.
[0016]
The communication application receives an on-hook / off-hook event from the expansion board 11 and performs processing corresponding to the event. If it is on-hook, it will end the call, and if it is off-hook, it will send the call.
[0017]
The tone detector 13 can detect whether or not the handset 5 is on the table 17. The MPU 14 of the expansion board 11 recognizes on-hook / off-hook from the signal of the tone detector 13 and notifies the application of on-hook / off-hook information through the bus.
In this way, a sound that can distinguish on-hook / off-hook is set to a specific frequency transmitted from the speaker 18 of the pedestal 17, and a device (tone detector 13) for detecting the sound is provided, so that on-hook is not used without using a special line. / Off-hook can be detected. Since the on-hook / off-hook can be automatically detected, the on-hook / off-hook click on the screen, which has been conventionally performed, is automatically performed, and the on-hook / off-hook operation with the keyboard or the mouse is unnecessary.
[0019]
