Description

[Detailed Description of the Invention] This invention relates to a receiver, and in particular to a receiver improved to notify the name of a broadcasting station by using sound rather than frequency or channel of broadcast radio waves.

Conventionally, dials, channel indicators, or digital indicators such as LCDs (liquid crystal displays) and LEDs (light emitting diodes) have been used to display radio reception frequencies and television reception channels.

All of these devices optically or visually notify the reception frequency and reception channel, and have the disadvantage that the user must visually confirm the broadcast frequency from the display.

This idea was made to eliminate the above-mentioned drawbacks, and by notifying the reception frequency and reception channel by voice, the user can know the reception frequency and reception channel without looking at the display. The aim is to provide a receiver that can

An embodiment of this invention will be described below with reference to the drawings. The drawing is a block diagram showing one embodiment of this invention. This configuration is applied to a normal electronically tuned radio with automatic tuning.

The received output of the receiving circuit 1 is given to a speaker 4 via a detection circuit 2 and an amplification circuit 3. These are well known from conventional radio receivers. Frequency up switch 14, frequency down switch 1
5. Search/step selector switch 16, FM/
The AM changeover switch 17 and the like are similar to those added to ordinary electronically tuned radios. Note that the search/step changeover switch 16 refers to "search".
and “step” mode changeover switch,
"Search" refers to a mode in which radio waves are received when the strength of radio waves at the receiving frequency is stronger than a preset strength, and "step" refers to the mode in which the received frequency is searched in units of 1 unit (for example, 9 kHz for AM broadcasting). It refers to the mode of reception that changes. The control circuit 5 often includes a microcomputer, and includes a reception frequency code latch 6,
Together with the reception frequency radio field strength measurement circuit 7, these are often used in electronically tuned radios with an automatic tuning function.

Frequency up switch 14, frequency down switch 15, and search/step changeover switch 1
6, the FM/AM changeover switch 17, and the audio notification switch are connected to a control circuit 5, and the control circuit 5 recognizes which state the switch is in. Reception area switch 19
is a switch that is set to the location where the user is in advance, such as the Hokkaido region, Tohoku region, Kanto region, etc.
Chubu-Hokuriku region, Kansai region, Chugoku region, Shikoku region,
Choose one of eight areas in the Kyushu-Okinawa region. By this selection, the area information is encoded by the reception area encoder and sent to the control circuit 5.

First, after turning on the power (not shown), the control circuit 5 automatically enters the broadcast wave reception state indicated by the FM/AM changeover switch 17, and stores the previously received broadcast frequency. In this case, the output of the received radio field strength measuring circuit 7 exceeds a certain predetermined value and is a sufficiently strong radio wave. A code corresponding to the appropriate broadcasting station name is obtained from the frequency-broadcasting station name storage circuit 9 using the area information given by the reception area changeover switch, and this code is sent to a voice synthesizer 12 including a voice memory 13, where the voice of the broadcasting station name is synthesized, and the voice of the broadcasting station name is uttered from the speaker 4 through an amplification circuit. At the same time, the received broadcast signal is sent from the detection circuit 2 to the amplification circuit 3 via the muting circuit 8 and is added to the speaker 4. This muting circuit 8 has a function of lowering the volume of the broadcast content to an appropriate level when the frequency is announced by voice, and the control circuit 5
controlled by

To change the reception frequency, proceed as follows.
First, when the "search" mode is selected with the search step changeover switch 16 and the frequency up switch 14 is pressed, the control circuit 5 operates the muting circuit 8 to apply muting. Then, a code increased by one unit is given to the code latch 6 of the reception frequency,
The receiving circuit 1 transmits the corresponding frequency to the received radio wave strength measurement circuit 7 when the strength of the received broadcast radio waves is sufficiently strong.
output to the control circuit 5, and the control circuit 5 decides to listen to this reception frequency,
The code of the broadcasting station name is selected and sent from the control circuit 5 to the audio synthesizer 12 using regional information, where the audio is synthesized and added to the amplification circuit 3. After the broadcasting station name is announced, the muting by the muting circuit 8 is canceled and the received broadcast can be listened to.
Here, a case has been described in which the frequency up switch 14 is selected, but the frequency down switch 1
When 5 is selected, the reception frequency decreases, and the subsequent operation is the same as when the up switch 14 is selected. AM or
When the receiving frequency range of FM broadcasting is exceeded, when the frequency exceeds the higher one, it goes to the lowest frequency,
When it exceeds the lower frequency, it operates to change to the highest frequency. In addition, select the step mode and press the up switch 14 or down switch 15.
When this is selected, the reception frequency is raised or lowered by one unit, the reception frequency is notified, and the listening state is entered. Furthermore, voice notification switch 1
Reference numeral 8 denotes a switch for notifying the name of the broadcasting station of the frequency being received during the broadcast. When this switch is pressed, the control circuit 5 gives the code of the name of the receiving broadcasting station currently being received to the speech synthesizer 12. The name of the broadcasting station currently being received is synthesized and announced from the speaker in the same way as described above. At this time, the muting circuit may be configured to operate.

According to this invention, since a means for notifying the name of the receiving broadcasting station by voice is installed, a receiver can be constructed without a display part such as a dial, and the effect is that the name of the receiving broadcasting station can be known without visual aid. There is.

Although the above has been described using AM reception as an example, the same procedure can be carried out in the case of FM reception, and the same effects can be obtained.

Further, in the case of a television or the like, similar operations can be performed with a similar configuration, and similar effects can be expected.
