Abstract

PURPOSE:To notify an incoming call without fail by changing the volume level and frequency of a ringing tone with lapse of time after detecting an incoming signal. CONSTITUTION:CPU 3 informed of the incoming call by an incoming signal detection circuit 2 counts the continuous time of the incoming signal and a control section 10 outputs a ringing tone signal having the prescribed ringing tone volume level and frequency to a speaker 11 until the prescribed time later. If no response comes within a prescribed time, the volume is made high level by the next prescribed period and a dissimilar frequency is set by the control section 10 at its output. Thus, the recognition of ringing tone is enabled from a distant place by increasing the ringing tone level thereby the incoming recognition is speedily and exactly enabled.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a telephone device, and more particularly, to a telephone device capable of automatically adjusting the volume and frequency of a ringing tone.

[0002]

2. Description of the Related Art In a conventional telephone device, when an incoming call arrives, a ringing tone for notifying the incoming call sounds. The volume of this ringtone is
It is set to be small when there is a user near the telephone unit or the surrounding environment is quiet, and large when there is a user away from the telephone unit or when the surrounding environment is noisy. A changeover switch for adjusting the volume is provided on the main body.

[0003]

As described above, in the conventional telephone device, the volume of the ringing tone can be adjusted by the changeover switch, but the adjustment is manually performed by the changeover switch in either of two levels or three levels. It is fixedly set at one level. Therefore, for example, once the volume level is set to a standard level or a high level, the volume at the time of an incoming call is too loud and annoying even if there are users near the telephone device, and conversely the volume is low. If the level is set, there arises a problem that a person is located away from the telephone device or the ringing tone cannot be heard when the ambient noise is large.

SUMMARY OF THE INVENTION An object of the present invention is to provide a telephone device that can notify an incoming call more reliably without being affected by the distance from the telephone device to the user and ambient noise.

[0005]

In order to solve the above-mentioned problems, a telephone device according to the present invention is a telephone device which detects an incoming signal from a telephone line and outputs a ringing tone signal to a speaker to generate a ringing tone. And a timer means for measuring an elapsed time from the detection of the incoming signal, and a level varying means for varying and outputting a volume level of the ring back tone signal in accordance with the measured elapsed time, and Also, frequency changing means for changing and outputting the frequency of the ringing tone signal in accordance with the measured elapsed time is also provided.

[0006]

In the present invention, the volume level and frequency of the ringing tone are automatically changed with the lapse of time after the incoming signal is detected, so that there is no user near the telephone device or ambient noise is generated. Allows quick response even in large cases.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be described with reference to the drawings. FIG. 1 is a configuration block diagram showing an embodiment of a telephone device according to the present invention. The call circuit 1 has a handset 5 and a transmitter 6, is connected to a telephone line, constitutes a call circuit, and enables a call. The incoming signal detection circuit 2 detects the incoming signal from the telephone line, sends the incoming signal to the CPU 3, and adjusts the ringing tone volume as described later. Under the control of the CPU 3, the ring back tone control unit 10 causes the speaker 11 to output a ring back tone. The key operation unit 4 is installed to perform dialing, data setting, etc.
It is composed of a display etc. The RAM 8 stores various kinds of information unique to the telephone device, and the ROM 9 stores the device control processing program executed by the CPU 3. Data exchange between the above-mentioned units is performed via the CPU bus 7.

When the incoming signal detecting circuit 2 detects an incoming signal from the telephone line, the CPU 3 which has received a signal to that effect from the incoming signal detecting circuit 2 starts counting the duration of the incoming signal. To do. Based on this counting result, the volume and frequency of the ringing tone are variably adjusted as shown in FIG.

Referring to FIG. 2, first, a ringing tone signal having a volume level V1 and a frequency F1 is generated by the ringing tone control section 10 from the speaker 11 until a predetermined time T1 elapses after an incoming call is detected. Is output. If there is no response within this time T1, the CPU 3 determines that there is no person around, sets the volume to the high level V2 for the next predetermined period T2, and sets the ringing tone signal of the frequency F2 different from F1. Is generated by the ring back tone control unit 10 and output from the speaker 11. Therefore, since the ringing tone level is increased, a person at a distant position can recognize the ringing tone and a quick response is possible. Further, if there is no response within the period T2, the volume level is further increased within the next period T3 and the frequency is set to F3, which enables a more reliable and quick response.

In the above-mentioned embodiment, the volume level and frequency of the ringing tone after the incoming call is set in three stages, but the level setting and the frequency setting are arbitrary and can be continuously changed. Obviously, it is also possible to select only one of the level change and the frequency change.

[0011]

As described above, the telephone device according to the present invention has the following characteristics:
Since the volume level and frequency of the ringing tone are automatically changed, a quick response is possible even when there is no user near the telephone device or when ambient noise is large.
