Abstract

PURPOSE:To preset a sound quality level in response to contents of broadcast to be selected by providing a memory storing a sound quality setting value in response to contents of broadcast or the like of a preset frequency so as to eliminate the need for manual sound quantity adjustment for each channel selection. CONSTITUTION:A frequency/sound quality memory 9 is connected to a tuner controller 7. In presetting the frequency and sound quality characteristic simultaneously, at first an equalizer memory (EQME) key 18 is depressed and after a switch 20 is turned on, the frequency is selected by a reception frequency setting means similar to that of a conventional means. Moreover, the sound quantity characteristic (CLASIC POPULAR, FLAT or the like) is selected by an equalizer select (EQSELECT) key 19 in response to the contents of broadcast resection. Then an ME key 16 to permit the frequency memory is depressed and a preset number key 17 is depressed to store the frequency and sound quality characteristic into the memory 9. Thus, the setting operation of the sound quality characteristic to the reception of the specific program is not required.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an electronically tuned radio, and more particularly to an electronically tuned radio in which a sound quality level corresponding to the selected broadcast content can be preset.

[Prior art] Radios in recent years use PLL (Phase Locke) technology.
Frequency conversion is performed using the d Loop (phase locked loop) method. Therefore, digitalization is achieved, and a frequency tuning radio that does not use analog tuning using a dial knob or the like can be configured. Furthermore, since frequency processing can be digitized,
It is also possible to incorporate a preset function that stores the reception frequency in the memory and calls up the preset frequency by pressing a button.

[Problems to be solved by the invention] However, in conventional electronically tuned radios, presets are limited to reception frequencies only, so the preset broadcast content is biased towards specific broadcast content. (For example, when playing jazz, classical music, etc.), it is necessary to adjust the sound quality every time you select a channel, which is inconvenient to use.

Therefore, it is desired to propose a radio that can preset one frequency and the sound quality.

SUMMARY OF THE INVENTION An object of the present invention is to provide an electronically tuned radio in which not only one frequency but also sound quality can be preset.

[Means for Solving the Problems] The above object is such that the sound quality setting value stored in the memory in accordance with the broadcast contents of the preset frequency is preset together with the frequency at the time of channel selection. As a result, the sound quality level corresponding to the broadcast content of the frequency corresponding to the operation of the preset number button is automatically preset, thereby eliminating the need for manual volume adjustment each time a channel is selected.

[Embodiments of the invention] An embodiment of the present invention will be described below with reference to FIG.

FIG. 1 is a block diagram showing one embodiment of the present invention. In FIG. 1, an antenna 1 is connected to an electronic tuning tuner section 2 that includes a high frequency amplifier circuit, a frequency conversion circuit, a local oscillator, an intermediate frequency amplifier, and a detection circuit. The output section of the tuner section 2 includes an electronic equalizer 3 whose sound quality level is variably adjusted by an external control signal.
is connected to the equalizer 3, and a volume controller 4 for adjusting the volume level is connected to the equalizer 3.

The low frequency output signal of the volume controller 4 is sent to the amplifier (
After the power is amplified by AMP) 5.

Electromechanical conversion is performed by the speaker 6.

Further, a PLL type tuner controller 7 which is stored in a memory 9 and which tunes to a designated frequency is connected to the tuner unit 2 . A frequency/sound quality memory 9 is connected to the controller 7, and an equalizer controller 8 is connected to the memory 9 and the electronic equalizer 3, each of which is controlled according to key operations on the display/operation section 10.

The display/operation unit 10 includes a display unit 11 that displays the reception mode (AM, FM), reception frequency, selected channel, etc., and an equalizer display unit 12 that displays the sound quality content selected according to the broadcast content. memory UP/DOWN (M UP/DOWN) key 13 for selecting the desired memory frequency;
Auto tuning (AUTOTUN) that starts automatic tuning at a constant speed from the lower end of the reception band to the upper end (or vice versa)
E) Key 14, select reception mode (AM/FM) 1
5. ME key 16 to enable frequency memory, preset (PR) to specify frequency memory and recall.
ESET) key 17, equalizer memory (EQ ME) key 18 that turns on the sound quality preset data switch 20 (located between the controller 8 and memory 9), and the equalizer select (EQ 5EL) key that sets the sound quality characteristics.
ECT) key 19.

In the above configuration, the reception frequency specified by the key operation of the display/operation unit 10 is set.

A tuner controller 7 tunes the tuner section 2 6
The tuner section 2 detects the high frequency signal, and applies the low frequency signal to the amplifier 5 via the equalizer 3 and volume controller 4, where it is amplified.

A speaker 6 is driven by this amplifier 5.

Next, preset operations for frequency and sound quality will be explained.

First, when presetting only one frequency, operate as follows (conventional radios also have this frequency presetting function).

After adjusting the frequency to be preset to the desired broadcasting station by operating the keys 13 or 14, the user presses the key 16 and then presses one of the preset keys 17. This will preset the selected frequency to the operated key number.

Next, a case where frequency and sound quality characteristics are preset at the same time will be described. First, the user presses the rEQ MEJ key 18 to turn on the switch 20, and then selects a frequency using the aforementioned receiving frequency setting means. More rEQ 5
Yacht in ELECTJ key 19, sound quality characteristics (CLAS

FLAT, etc.) is selected depending on the content of the broadcast reception.

Thereafter, by pressing the rMEJ key 16 and the preset number key 17, one frequency and sound quality characteristic are stored in the memory 9.

FIG. 2 is a flowchart showing an example of preset processing in the present invention.

First, a reception frequency is set (step 21), and it is determined whether it is a preset frequency (step 22). Next, it is determined whether the key 49 has been operated (step 23
), and if it has been operated, it is determined whether or not the sound quality characteristics have already been preset (step 24), and if the sound quality characteristics have not been preset, the sound quality characteristics are set (step 29).
do. On the other hand, if the sound quality characteristics are preset, rM
It is determined whether the EJ key 16 has been operated (step 25). If the rMEJ key 16 is on, a preset mode is set (step 26). Next, the operation of the preset key 17 is determined (step 27), and if the preset key 17 has been operated, the frequency and sound quality characteristics are preset (step 28).

On the other hand, if the rEQ MEJ key 18 has not been operated, it is determined whether or not the rMEJ key 16 has been operated (step 30), and when the key 16 has been operated, the preset mode is entered (step 31). Next, it is determined whether or not the preset key 17 has been specified (step 32).
After that, the frequency is preset (step 33).

Although the above example shows the preset sound quality characteristics for a radio, it goes without saying that the present invention can also be applied to a television receiver or the like.

[Effects of the Invention] As explained above, according to the present invention, it is possible to preset the frequency and sound quality characteristics according to the broadcast content of the frequency preset station, so that the setting operation of the sound quality characteristics for reception of a specific program is simplified. becomes unnecessary.
