Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a speaker device. Specifically, by providing a plurality of speakers and a display means for displaying that an audio signal has been supplied, it is possible to easily visually recognize which frequency band is being received when connected to, for example, a dual band transceiver. The present invention relates to a speaker device.

[0002]

2. Description of the Related Art Conventionally, a transceiver for an amateur generally has a built-in speaker. When this transceiver is used in an automobile, for example, it is often installed in an unobtrusive place such as under the dashboard, so that it is difficult to hear the sound from the built-in speaker. Therefore, it is common to connect a relatively small external speaker to the audio signal output terminal of the transceiver and attach the external speaker to a position where it is easy to hear, for example, the upper side of the dashboard for use.

[0003]

However, the bandwidth used by the transceiver is 144.00 MHz to 145.99 M.
430M in addition to the Hz frequency band (144 MHz band)
HZ-439.99 MHz frequency band (430 MHz
It is becoming common to do it together. Along with this, so-called dual band transceivers capable of simultaneously receiving signals in both the 144 MHz band and the 430 MHz band have become widespread. This dual band transceiver is for the 144MHz band and 430MH
It has two audio signal output terminals for the z band.

When the dual band transceiver is used in an automobile, an external speaker is connected to each of these two audio output terminals for use. As a result, when a signal is received in the 144 MHz band or the 430 MHz band, the calling voice is reproduced from the corresponding external speaker. At this time, in order for the user to answer the call, 144 MHz is required according to the other party.
It is necessary to select either the band or the 430 MHz band for transmission. However, it is difficult to determine from which speaker the sound is reproduced only by the sound.

Therefore, the user has to confirm which frequency band is being received on the display of the transceiver body. However, since the transceiver main body is installed in an inconspicuous place in the automobile as described above, it is difficult to immediately see the display of the main body. As described above, there is a problem that the user cannot immediately respond to the calling voice.

When a dual-band transceiver is installed and used in a vehicle, when one speaker outputs a calling voice to itself, the calling voice of another person reproduced from the other speaker interferes with the call. May become. In such a case, the user needs to adjust the volume on the transceiver main body to reduce the volume of the other speaker. However, as described above, since the transceiver main body is often installed in a position where it is difficult to reach in the automobile, there is a problem that the volume adjustment is troublesome.

Therefore, the present invention solves the above-mentioned problems, and simultaneously reproduces a plurality of audio signals from a dual band transceiver and easily determines which audio signal is being reproduced. A speaker device that can be identified and whose volume can be easily adjusted is proposed.

22b respectively. Further, the power cord is connected to a cigar socket or the like of the automobile.

When power is supplied, the LEDs 8c-8e emit green light. This green light is appropriately diffused by each knurl portion 13 shown in FIG. 1 and guided upward by the light guide plate 11. As a result, the entire light guide plate 11 is illuminated in green light with an illumination effect,
It will indicate that power is being supplied. Since the LEDs 8c and 8e are arranged symmetrically with respect to the central LED 8d with a certain distance, the light guide plate 11 is illuminated with green over substantially the entire surface. .

Then, for example, in FIG. 5, 430 MHz
When the voice signal S1 from the band is input from the jack 22a, it is amplified by the amplifier 23a and reproduced as voice from the speaker 3a. The LED drive unit 24a receives the audio signal S1 to cause the LEDs 8a and 8b to emit constant light. The light from the LEDs 8a and 8b is red light, is appropriately diffused by each knurl portion 13 shown in FIG. 1, and is guided upward by the light guide plate 11. Since this red light has a stronger color tone than the green light emitted from the LEDs 8c to 8e, the right end portion of the light guide plate 11, that is, "43".
The character "0 MHz" is lightly illuminated in red with an illumination effect, which indicates that the audio signal from the 430 MHz band is being reproduced.

On the other hand, when the audio signal S2 from the 144 MHz band is input from the jack 22b, this is amplified by the amplifier 23b and reproduced as sound from the speaker 3b. Further, the LED drive unit 24b receives the audio signal S2, and the LEDs 8f and 8g emit constant light. Since the light from the LEDs 8f and 8g is red light, FIG.
Properly diffused by each knurled part 13 shown in
It is guided upward by the light guide plate 11. This red light is LE
Since the tint is stronger than the green light emitted from D8c to 8e, the left end portion of the light guide plate 11, that is, "144 MHz".
The character “” is illuminated in red light with an illumination effect, which indicates that the audio signal from the 144 MHz band is being reproduced.

In this way, the characters corresponding to the speaker 3a or 3b reproducing the audio signal appear to be illuminated in red. Therefore, for example, when the speaker device 1 is mounted on the dashboard of a car, the user is in the 144 MHz band. Alternatively, it is possible to easily confirm from which frequency band the 430 MHz band is the voice. Therefore, the user can immediately respond in the frequency band corresponding to the calling voice.

Further, since the volumes 14a and 14b are provided corresponding to the respective speakers 3a and 3b, the volume of the unused speaker 3a or 3b should be lowered when making a call in one frequency band. Because you can
A call can be comfortably made without the call voice of another person interfering with the call.

In this example, 144 MHz band and 430 M
Although the case where two audio signals from the Hz band are reproduced has been described, it goes without saying that the present invention is not limited to this, and audio signals in other frequency bands can also be reproduced. When playing sound from other frequency bands, instead of the transparent sticker 15 with "144MHz" and "430MHz" printed, another transparent sticker with characters representing that frequency band is pasted. can do.

In this example, the case where the audio signal is connected to the dual band transceiver 21 has been described, but it is necessary to simultaneously reproduce two or more systems of audio signals, and it is necessary to identify which audio signal is being reproduced. It is also possible to connect to other devices that have.
