Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a ring tone control device that controls and transmits a ring volume according to the environmental condition at the time of incoming call in a ring signal receiving circuit of a telephone terminal. .

(Prior Art) Conventionally, there has been a calling signal receiving circuit for a telephone terminal as shown in FIG. LL and L2 are telephone terminals, 1 is a DC blocking capacitor, and 2 is a magnetic bell.

Next, to explain the operation of this circuit, when a calling signal from the exchange is received from the telephone terminals Ll and L2, the DC voltage is blocked by the DC blocking capacitor 1, and only the AC signal is applied to the magnet bell 2. Heavy bell 2 rings. The volume of the ringing tone at this time is a fixed volume or a volume specified by a volume adjustment knob (not shown).

(Problem to be Solved by the Invention) However, in the above-mentioned devices, the ringer volume is determined by the volume control knob, etc., so if the volume is set to be high, the user will feel noisy at night. On the other hand, if you set the volume to be low, you may not be able to hear the ringing tone during the daytime. Therefore, there is a problem in that the user has to adjust the volume adjustment knob and the like each time to obtain the appropriate volume.

As described above, it is an object of the present invention to provide a ring tone control device for a telephone extension terminal that eliminates the need for the user to adjust the volume control knob or the like according to the environment and has excellent operability.

(Means for Solving the Problems) In order to solve the above problems, the present invention provides a ringing signal detection circuit for detecting an incoming call, and an oscillation circuit for receiving an incoming call detection signal from the ringing signal detection circuit and sending out a ringing tone. a state determination circuit that determines the state of the environment when the oscillation circuit sends a ring tone; and a volume control circuit that controls the volume of the ring tone of the oscillation circuit based on the state determined by the state determination circuit. Prepared.

(Function) According to the present invention, when the calling signal detection circuit detects an incoming call, the oscillation circuit that receives the output signal is activated. Then, the volume control circuit controls the volume of the oscillation circuit based on the state of the environment at the time of incoming call, which is determined by the state determination circuit.

(Embodiment) FIG. 1 is a system diagram of a ring tone control device for a telephone terminal showing an embodiment of the present invention.

In the figure, 3 is a ringing signal detection circuit that detects an incoming call, 4 is an oscillation circuit that sends out a ringing tone upon receiving the incoming call detection signal, 5 is a volume control circuit that controls the volume of the ringing tone, and 6 is a ringing signal detecting circuit that detects an incoming call. 7 is a sounding body, and LL and L2 are telephone terminals. The state determination circuit 6 is composed of, for example, a timer, a photodetection element, etc. When using a timer, for example, the maximum volume is set from 9 a.m. to 5 p.m., and the medium volume is set from 5 p.m. to 100 p.m. In order to keep the volume to a minimum from 10:00 pm to 9:00 am, control information of an appropriate volume value according to the user's requirements is set in advance, and each control information is transmitted to the volume control circuit 5 according to each time period. Output to. In addition, when using a photodetector, −
For example, you can set the maximum volume when the room is bright and the minimum volume when it is dark, and control the volume in advance based on the light detection results. Output to circuit 5.

Next, the operation will be described. When an incoming call signal arrives from the office line, the calling signal detection circuit 3 is activated, and the oscillation circuit 4 is activated by the incoming call detection signal. The oscillation output signal of the fourth oscillation circuit is controlled by the volume control circuit 5 based on the determination result of the environmental condition such as the time of day or brightness by the state determining circuit 6, and is supplied to the sounding body 7, and the sounding body 7 is supplied to the sounding body 7 depending on the environmental state. The phone rings and rings at an appropriate volume according to the call.

(Effects of the Invention) As explained above, according to the present invention, the appropriate volume according to the environment is always automatically obtained, so the user does not have to adjust the volume adjustment knob etc. each time, and the operability is improved. An excellent ring tone control device can be provided.
