Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sound generator for a motorcycle capable of enjoying music and the like in a safe driving state while a motorcycle such as a motorcycle or a bicycle is running.

[0002]

2. Description of the Related Art There are various types of in-vehicle audio equipment such as a car stereo, a CD (compact disc) player or an MD (mini disc) player mounted on an automobile or a truck. Tend to be On the other hand, there is no audio equipment that can be mounted on motorcycles such as motorcycles, except for a few types of motorcycles. Therefore, when performing long-distance driving or transport work on a motorcycle, listen to music output from the portable headphone stereo with earphones or speakers with a built-in helmet in order to relax and feel safe driving. That is the fact.

[0003]

However, listening to music or the like with an earphone or a built-in helmet speaker while driving on a motorcycle is difficult to hear sounds from the surroundings, especially a warning sound and a sound of a car approaching from behind. This is not preferable for safe driving, because it is not possible to sufficiently hear the sound required for driving. In particular, when performing transport work or long-distance driving by motorcycle, information such as constantly changing traffic conditions and weather information is essential, but it is not possible to listen to the broadcast of the radio receiver with earphones while driving the motorcycle. However, safe driving is not absolutely permissible. Therefore, in recent years, there has been a demand for a system that can reliably listen to a radio broadcast or the like without hindering safe driving of a motorcycle or the like.

[0004] In addition, while a motorcycle is running, there is a problem in that the ring tone of a portable telephone, which has been almost indispensable in recent years as a means for transmitting communication for mobile use, can hardly be heard due to the sound of the engine of the own vehicle or ambient noise. Furthermore, if you are riding a large motorcycle for two people, you may want to talk between the driver and the vehicle in the backseat. It is difficult to have a smooth conversation by wearing. On the other hand, the number of motorcycle thefts is overwhelmingly higher than that of automobiles, and effective prevention measures are being sought to prevent this.

The present invention has been made in view of the above-mentioned conventional problems, and allows the user to enjoy music and the like in a safe situation in which the surrounding sounds can be distinguished while driving a motorcycle or the like. Provides a sound generator for a motorcycle that can reliably hear the ringtone of a telephone, can communicate smoothly without any trouble in the case of a two-seater on a motorcycle, and has a motorcycle anti-theft function. It is intended to do so.

[0006]

In order to achieve the above object, a two-wheeled vehicle sound generating device according to the present invention includes a fixing device mounted on a front portion of a driver's seat of a two-wheeled vehicle, and a driver or a passenger of the two-wheeled vehicle. Comprises a portable device that is carried around the body, wherein the portable device includes a sound source,
A wireless transmitter that transmits an audio signal from the sound source through a transmission antenna by radio waves, wherein the fixing device unit receives a radio wave transmitted from the transmission antenna through a reception antenna; And a speaker for outputting a received signal of the apparatus as sound.

In this two-wheeled vehicle sound emitting device, a sound source provided in the portable device, for example, an audio signal of a portable CD player, a radio receiver, a portable MD player, a tape recorder, or the like is transmitted as a radio wave from a transmitting antenna of a wireless transmitter. This radio wave is received by the wireless receiver through the receiving antenna and is output as sound from the speaker. Therefore, the driver of the motorcycle, while driving the motorcycle,
Music and the like reproduced and output from the speaker can be enjoyed. Here, if a speaker having extremely high directivity is used as the speaker, it does not bother nearby residents, pedestrians, or other vehicles running side by side with the two-wheeled vehicle, and the driver can: Listening to the music output from the speaker in front of you and voices from other people as a synthesized sound, you can relax your feelings while listening to music and drive the motorcycle while approaching from the alarm sound or from behind. It is possible to sufficiently recognize the direction of the sound source of the sound necessary for driving such as the sound of a car, and there is no problem in keeping safe driving in mind.

Further, if a portable telephone is provided as a sound source in addition to the above-mentioned sound source, when a portable telephone receives a radio wave while driving a motorcycle while enjoying music, an output signal of the portable telephone is output. The radio transmitter transmits the radio wave as a radio wave through the transmitting antenna, and the radio wave is received by the radio receiver through the receiving antenna to sound the speaker.
The ringtone of the mobile phone output together with music or the like from the speaker can be reliably heard even when the helmet is worn.
Therefore, the driver stopped the motorcycle quickly on the side of the road,
Communication can be performed by a mobile phone. In addition, when carrying out transport work or long distance driving by motorcycle, if a radio receiver is used as a sound source,
There is a great practical merit that indispensable information such as ever-changing traffic conditions and weather information can be reliably heard in real time without any hindrance.

Further, in the above invention, the fixing device section includes a vibration sensor and an alarm signal generator for outputting an alarm signal for starting by receiving a vibration detection signal from the vibration sensor and outputting an audio signal from the speaker. And the portable device unit may have a changeover switch for switching the presence or absence of input of a vibration detection signal from the vibration sensor to the alarm signal output circuit.

[0010] Thus, when the motorcycle is parked and separated from the motorcycle, if the driver turns on the changeover switch, someone performs a mischief, such as stealing the motorcycle or removing the speaker of the fixing device. When the motorcycle is moved without permission for the purpose, the vibration sensor detects the vibration of the motorcycle at that time and outputs a vibration detection signal. The vibration detection signal activates the alarm signal generation circuit that has been switched to the ON state as described above, so that the alarm signal output from the alarm signal generation circuit is output as an alarm sound from the speaker, and the output of the alarm sound causes theft. And mischief can be stopped beforehand.

Further, in the above invention, the portable device has two portable devices, each of which is mounted inside a helmet and inputs a voice of a motorcycle driver or a passenger to the wireless transmitter. A configuration including at least a microphone can be adopted.

[0012] Thus, the driver can reliably confirm the incoming call of the mobile phone by the output sound from the speaker even under the noise environment while traveling on the motorcycle, stop the motorcycle on the side of the road, and remove the hemet. You can communicate with the other party by responding through the microphone. In addition, since the portable device unit has two which the driver and the passenger carry individually, these portable device units transmit the voice of the driver or the passenger input to the microphone from the wireless transmitter. It can be transmitted as radio waves through an antenna, and each of the audio signals is output from a speaker and can be heard by both the driver and the passenger. Therefore, the driver and the passenger
While driving a motorcycle, etc., they can talk with each other without any trouble.
