Embodiment Construction

[0017] In order to illustrate the technical content, structural features, achieved goals and effects of the present invention in detail, the following will be described in detail in conjunction with the embodiments and accompanying drawings.

[0018] see figure 1 , figure 1 Shown is a schematic circuit diagram of the ringer volume control device 1 . The circuit of the bell volume control device 1 includes a light-sensitive responsive circuit 10, which is electrically connected to the light-sensitive responsive circuit 10 and accepts the bell volume control circuit 11 of the output signal from the light-sensitive responsive circuit 10, to the bell The volume control circuit 11 inputs the ring signal and is modulated by the ring volume control circuit 11 , the ring current output circuit 12 , and the speaker 13 electrically connected to the output terminal of the ring volume control circuit 11 .

[0019] see figure 2 , and see in conjunction with figure 1 , figure 2 Shown...

Abstract

The invention relates to a ring volume controller, which comprises a photosensitive inductive circuit; a ring volume control circuit connected electrically with the photosensitive inductive circuit and receiving an output signal from the photosensitive inductive circuit; a ring current output circuit that generates a ring signal and outputs the ring signal to the ring volume control circuit and the ring signal is modulated by the ring volume control circuit; and a loudspeaker connected electrically with the output end of the ring volume control circuit. A photoresistance is arranged outside a mobile phone provided with the ring volume control circuit. The invention modulates the ring current output by the ring current output circuit by arranging the photoresistance on the outer surface of the mobile phone and through a first variable resistor and a second variable resistor, so that the mobile phone with the ring volume controller is large in ring volume in the day time and gentle in ring volume at night so as to remind incoming calls without influencing the rest of users.

Description

technical field [0001] The invention relates to the field of communication products, in particular to a ring volume control device and a telephone with the device. Background technique [0002] In modern society, the use of telephones is quite common, and telephones have become an important tool for communication. [0003] The ringing circuit in the telephone is mostly composed of integrated circuits, mainly including an input circuit, a dual-tone oscillator circuit, and an output circuit. Its function is to convert the 25Hz ring current voltage into two audio voltages, and drive a high-impedance piezoelectric buzzer or a low-impedance dynamic speaker to ring at a certain period to indicate an incoming call from an outside line. [0004] Most of its electric bells of the telephones used at present are mechanical and electronic, and the ringtone is loud and the volume cannot be adjusted. It seems too noisy and surprising to families or quieter offices. In addition, as the p...
