DE10014135A1 - Cordless or conventional telephone with an arrangement for audible signaling of the time as requested by the user or automatically at regular time intervals to overcome drawbacks of LCD time displays - Google Patents

Abstract

Cordless or wire connected telephone in which time information can be given to the user in an audible manner. Audible time signaling can be triggered by the user or can be automatically given at regular time intervals. If the connection is an ISDN connection then the precise time can be taken from the D channel.

Description

The invention relates to a phone with devices for accurately determining the Time, which according to the invention is clear and simple on the phone user can be transmitted.

It is known to generally use inexpensive phones with display units LCD displays for displaying various information. So can, for example, be the selected one for some telephone versions Telephone number, the name of a subscriber to be called or that of one Callers are shown on the display unit. Even the display of The date and time on the display is known.

The disadvantage of these displays is that they are often difficult or bad Lighting conditions are not read at all. The latter because the cheaper ones Displays work on the liquid crystal principle and mostly on one Avoid backlighting. In addition, the reading angle in certain limits must be kept, which further restrictions in the Readability entails, since the position of the viewer is not arbitrary. The time and date are very often required and must be entered under the mentioned circumstances. Furthermore, it is currently at Start of the conversation or during the conversation advantageous, quick and easy Get time information. So, regardless of Network operator fee information, an estimate of costs a telephone connection.  

The object of the present invention is therefore to provide a telephone at which is the transmission of the time and date to the user can be carried out easily, quickly and clearly.

This task is combined with the preamble of claim 1 solved that additional information acoustically via a in the phone located sounder or via the listening device in the telephone handset to the Users are submitted.

Advantageously, the user is either automatically, for example at the beginning of the call, on request by pressing a key or to previously programmed times, the time and, if necessary, also the date communicated through a speech synthesizer. The display does not have to to be viewed as.

An advantageous design of the phone provides the time when connected derived from the D-channel information to the ISDN. So it is always the exact one Time and date available without adjustments.

In the case of analog phones, it makes sense for one to use it comfortably Integrate receivers for a time signal transmitter, such as DCF-77. This Receivers are now inexpensive to manufacture, so that the Final price of a telephone equipped with it is only slightly more expensive.

If the telephone is operated on a private branch exchange, the Time information also obtained from a central clock located there become. The transmission can take the form of analogue telephones CLIP function take place in ISDN devices in the subaddressing.

Since the phone has a numeric keypad and a clock, it can be more advantageous an alarm function can be provided. The wake-up time is over the  Dial pad entered. Using the signal generator in the phone a call signal can be generated at the preselected time.

Further details of the invention are shown in the drawing described schematically illustrated embodiments.

Here, the only figure shows the connection of the devices for Time spent on a phone.

A time signal receiver 2 is connected to the microprocessor 4 controlling the telephone. This provides information about the date and time. The microprocessor evaluates this received data and synchronizes its internal clock. When a corresponding key is pressed in the control panel 5 of the telephone, the speech synthesizer 1 is programmed by the microprocessor 4 with the data required for time output. The time announcement can then be added to the handset 6 to the information coming from the remote station by means of a connection to the analog part 3 of the telephone. If there is an ISDN connection, it is possible to derive the time information from the information arriving in D channel 6 and to synchronize the internal clock of the microprocessor.

Claims (7)

Telephone according to claim 1, characterized in that time information acoustically output via a sounder located in the phone become. 3. Telephone according to claim 1 or 2, characterized in that Time information about the hearing device is output in the telephone handset become. 4. Telephone according to one or more of claims 1 to 3, characterized characterized in that time information from ISDN features be won. 5. Telephone according to one or more of claims 1 to 3, characterized characterized in that the time information from the broadcasts of a Time signal transmitter can be won. 6. Telephone according to one or more of claims 1 to 3 which at one Private branch exchange is operated, characterized in that the Time information obtained from a central clock in the secondary stable system becomes 7. Telephone according to one or more of claims 1 to 6, characterized characterized in that an alarm function is provided.
