Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an audio device mounted on a motorcycle.

[Prior Art] In recent years, due to advances in semiconductor technology, audio equipment such as radio equipment, cassette magnetic tape equipment, and
Audio amplifiers and the like have also become smaller and more reliable. For this reason, audio equipment that integrates these features has appeared, and is being installed not only in cars but also in motorcycles.

[Problems to be Solved by the Invention] However, when riding a motorcycle, it is dangerous to take one's hands off the handlebars unnecessarily, so it is necessary to be able to operate the audio equipment while holding the handlebars. For this reason, an operating section for operating the audio equipment was separately provided near the grip section of the handle. A large number of switches are required for various operations, and if there are too many switches for a motorcycle that is not necessarily operated while looking at the user's hand, operation errors may occur. In addition, the number of signal wires required to connect the audio equipment body corresponds to the number of operation switches, and the wiring is generally done on the back side of the handle, and the thin handle is used for engine control, turn signal control, etc. It was full of complicated signal wiring for various purposes.

[Means for Solving the Problems] The present invention has been made for the purpose of solving the above-mentioned problems, and as a means for solving the problems, the present embodiment has the following configuration. .

That is, the motorcycle-mounted audio device includes a player device and a radio device, and a switch for operating the audio device with different functions is disposed near each grip on one side of the operating handle of the motorcycle;
a detecting means for detecting whether or not a media is stored in the player device; and when the detecting means detects that the media is stored, it determines an operation input from an operating switch as an operation input for the player device; and input processing means for inputting operation to the radio device.

[Function] With the above configuration, it is possible to reasonably reduce the number of operation switches and provide a safe motorcycle-mounted audio device that does not cause any inconvenience in operation.

[Example] Hereinafter, an example according to the present invention will be described in detail with reference to the drawings.

FIG. 1 is a partial external view of this embodiment equipped with an embodiment according to the present invention, in which 1 is an audio equipment, 2 is a
is an instrument panel, 3 is a right handle, 4 is a left handle, 5 and 6 are switches for operating the audio equipment 1 of this embodiment, and 7 and 8 output unique modulation signals to the inputs of the switches 5 and 6. modulation section, 11, 12
is a photocoupler, and 11a and 12a are light-receiving elements on the audio equipment side that output electrical signals proportional to the amount of received light. 11b and 12b are light emitting elements that output modulated light according to modulation signals from modulation sections 7 and 8. The light emitting element 11b and the light receiving element 11a face each other, and the modulated light from the light emitting element 11b is received by the light receiving elements 11a and 12a. This received modulated signal is sent to the audio equipment 1 via a pair of signal lines 13 and 14. Moreover, 9a and 9b are speakers that output acoustic signals.

In FIG. 1, the light-receiving elements 11a, 12a and the light-emitting elements 11b, 12b are arranged near each other, but the light-receiving elements are not limited to such positions, and the light from the light-emitting elements is Any position is sufficient as long as it can receive light well. That is, by optimizing the mounting positions of the light receiving element and the light emitting element, the light receiving element can be mounted on the panel portion or side surface of the surface of the audio equipment 1. By doing this,
Wiring for the handle parts 3 and 4 to the audio equipment can be eliminated.

Details of the right handle operating switch 5 of the audio equipment 1 are shown in FIG. 2A, and details of the left handle operating switch 6 are shown in FIG. 2B.

In FIG. 2A, 21 is an accelerator, 22 is an operation switch unit consisting of touch switches, DN switch 25, UP switch 26,
It is composed of an SK switch 27. Each switch has different functions depending on the control described below, depending on whether it is in radio operation mode or cassette operation mode. The DN switch 25 functions as a step-down (DOWN) switch for the receiving frequency for manual tuning in the radio operation mode, and functions as a rewind (REW) switch in the cassette operation mode. Similarly, the UP switch 26 serves as a one step-up (UP) switch for the received frequency when in the radio operation mode, and serves as a first forward (FF) switch when in the cassette mode. Note that these switches can be set to 5 consecutive times in radio operation mode.
If you hold it down for more than a second, the reception frequency will increase or decrease continuously until you release the switch. In addition, the SK switch 27 is in auto-tuning mode when in the radio operation mode, and when it receives broadcast radio waves of a predetermined strength or higher, it automatically fixes the reception frequency there, enters the state of receiving the broadcast of the relevant broadcast station, and then repeats the broadcast again. When pressed, it becomes an auto-tuning switch that allows reception of the next broadcast station, and when in cassette operation mode, changes the tape running direction and sets tape playback mode.

Further, 24 is a touch switch 25 of the modulation section 7,
The input signals from 26 and 27 are discriminated, modulated to the corresponding frequency, and the light emitting element 11b is activated at the modulated frequency.
This is a control circuit a that causes the light to emit light.

On the other hand, in FIG. 2B, 31 is a clutch, 32
is a touch switch unit, which includes a DN switch 35 and an UP switch 36 for changing the volume of the radio or cassette tape, and each time the switch is pressed, the volume changes by 2 dB. If you hold down the switch for more than 5 seconds, the volume will increase or decrease in 2dB increments. and,
When you release the switch, the current volume is maintained. Also, 37 is a switch for indicating the direction of the motorcycle, and by operating this switch,
A corresponding direction indication display is made.

Further, 34 is a touch switch 35, 3 of the modulation section 8.
This is a control circuit b that discriminates the input signal from No. 6, modulates it to a corresponding frequency, and causes the light emitting element 12b to emit light at the modulated frequency.

FIG. 3 shows a control block diagram related to the audio equipment of this embodiment having the above configuration.

Components in the figure that are the same as those in FIGS. 1 and 2 A and B are designated by the same reference numerals, and explanations thereof will be omitted.

The control unit 40 controls the entire device according to a program stored in the ROM 41. Reference numeral 42 denotes a timekeeping section for keeping time, and the control section 40 displays the timing results of the timekeeping section 42 on the display section 43 when in the cassette operation mode, and displays the reception frequency on the display section 43 when in the radio operation mode. Further, reference numeral 44 denotes an operation section disposed on the surface of the audio equipment body, on which various operation switches for operating a cassette and operating a radio are laid out, similar to a normal car stereo. Further, the modulated signals received by the light receiving elements 11a and 12a are sent to the demodulation circuit 45,
Here, it is demodulated and output to the control section 40 as a signal corresponding to each input switch. This switch input signal is the same signal as the corresponding switch input from the operating section 44. The modulation processing in the modulation circuits 24 and 34 is a frequency modulation method, in which a specific predetermined frequency is assigned to the input switch, and the switch input modulates the assigned frequency to cause the light emitting elements 11b and 12b to emit light. The modulated light is received by the light receiving elements 11a and 12a, and the frequency sent by the demodulation circuit is analyzed.
Determine the input of the corresponding switch.

Note that this modulation method is not limited to this, and may be phase modulation, FM modulation, or AM modulation. Moreover, the same effect can be obtained by using radio waves instead of optical coupling between the modulation circuits 24, 34 and the demodulation circuit 45. Reference numeral 46 denotes an amplifier unit that drives the speakers 9a and 9b, and includes a volume control mechanism that operates according to instructions from the control unit 40.

Further, 50 is a cassette magnetic tape reproducing device (CMT), and 60 is a radio tuner. Since these configurations are well known, their explanation will be omitted. however,
The CMT device 50 includes a cassette storage switch 51.
It is a switch that is turned on when a cassette tape is stored in the CMT device 50 and turned off when the cassette tape is removed. This switch signal is directly input to the control section 40. Then, if the cassette storage switch 51 is on, that is, a cassette tape is stored in the CMT device 50, the control section 40 determines that the mode is the cassette operation mode, and the modulation input to the demodulation circuit 45 is input to the cassette operation switch and the cassette operation mode is established. If the switch is on, it is determined that it is the radio operation mode, and the demodulation circuit 4
5 to inform that the modulation input is the input of the radio operation switch. The demodulation circuit 45 that receives this executes demodulation processing according to the instruction.

However, the demodulation circuit 45 is configured to simply demodulate the received modulated signal, and when the control section 40 receives this demodulated signal, it checks the cassette storage switch 51 to determine which operation input it is. Good too.

When the control unit 40 determines the input of each switch in this way, it outputs a control signal corresponding to the CMT device 50 or the radio device 60 to control the corresponding device. Here again, the configuration may be such that the control unit directly controls each device, and the control unit 40 directly controls each device.
Control of REW, FF, and FWD of the CMT device, selection of read information, output control to the amplifier circuit 46 (including volume control), tuning control of the radio device, etc. may be controlled.

As explained above, according to this embodiment, the operation switch for the motorcycle-mounted audio equipment is provided on the left and right handles in addition to the operation panel surface of the audio equipment main body, and the handlebar switches The functions are divided into different functions to improve operability.

In addition, considering that the operation switch must be placed in the limited space of the handle, it is difficult to listen to the playback sound etc. from the CMT device 50 when a cassette tape is stored in the CMT device 50. , it is determined that it is an operation input to the CMT device 50, and if no cassette tape is stored,
By determining that it is the time to listen to the radio device 60 rather than the CMT device 50, and assuming that it is a radio operation input, one switch can be used as a switch with two functions, and the number of operation switches can be reduced. It is possible to create an audio device that is small in number and easy to operate.

In addition, since the signal line from each operation switch is modulated and sent to the device body, the operation switch and the device body can be connected with only one pair of signal wires, making the device easy to wire and easy to use. I can do it. Moreover, by sending this modulated signal to the main body side using a radio communication such as a photocoupler, wiring is easier, and it is not affected by inconvenient noise or the like. Furthermore, the operation switch section and the main body of the device can be separated very easily during maintenance. Therefore, even when changing equipment or replacing the operating switch section, the operating section and the main body section can be easily separated without impairing reliability.

The above explanation is based on Radio Chu 60 and
Although the audio equipment equipped with the CMT device 50 has been described, the present invention is not limited to this.
In place of the device 50, a compact disk device is provided, and instead of the cassette storage switch 51, a media storage detection switch is provided to detect whether or not a compact disk media is stored in the device, and the detection output of the switch is utilized. The function of the operating switch may be changed by

[Effects of the Invention] As explained above, according to the present invention, it is possible to provide a safe motorcycle-mounted audio device in which the number of operation switches can be reasonably reduced and there is no inconvenience in operation.
