Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a volume control device for telephone equipment.

[Conventional technology]

Conventional telephone equipment is equipped with a speaker volume for adjusting the listening volume and a sliding switch for switching the ringing volume.
The volume of each was adjusted.

``This configuration has the advantage of being able to set each volume independently, but it requires a volume and slide switch, and each knob must be attached to the body, making it structurally unsatisfactory. It was complicated and less economical. Furthermore, because of the design, the knobs created holes or protrusions in the body, which did not give a clean appearance.

Therefore, in order to reduce the number of knobs and economize on parts, there is a device that functions both for adjusting the speaker receiving volume and for adjusting the ringing volume. With this configuration, it is possible to reduce the number of polyneem or slide-type switches and knobs, making it more economical, but the disadvantage is that it is not possible to change the speaker listening volume and the ringing volume independently, resulting in poor operability. . Also, although the number of knobs is reduced, they are still arranged in rows, so the degree of freedom in design does not improve.

On the other hand, in recent years, handsets have come equipped with a function that allows the volume of a conversation to be increased or decreased by inputting an input operation to adjust the volume. In order to realize this function, it is necessary to provide a locking switch or a means to adjust the volume by detecting the input operation for volume adjustment with a non-locking switch in a control circuit. Input buttons must be provided on the body, which imposes design and space constraints.

[Problem to be solved by the invention]

It is an object of the present invention to solve the above-mentioned problems in telephone equipment, and to provide a telephone equipment that has a simple structure, is economical, and has a good design while maintaining good operability in that each volume can be adjusted individually. The purpose of the present invention is to provide a volume control device.

[Means to solve the problem]

In order to achieve the above object, the present invention provides a telephone device equipped with one or more of handset receiving means, speaker receiving means, and incoming call audible display means, in which the handset receiving volume, the speaker receiving volume, or the incoming call volume can be increased or decreased. A volume adjustment switch for individually instructing each, a volume adjustment means for a speaker receiving volume or an incoming call volume, and a control circuit;
Equipped with memory.

[Effect]

In such telephone equipment, when the volume control switch instructs to increase or decrease the handset listening volume, the control circuit detects this and controls the talking circuit to adjust the handset listening volume, and adjusts the volume. When the switch instructs to increase or decrease the speaker listening volume or the ringing volume, this is detected and the volume adjustment means is controlled to adjust the speaker listening volume or the ringing volume, and the result of the volume adjustment is stored in memory. to prepare for the next operation.
