Description

[Detailed Description of the Invention] [Industrial Field of Application] This invention relates to an electronic siren loudspeaker suitable for application to two-wheeled vehicles such as motorcycles, for example.

[Prior Art] Generally, a motorcycle driver operates various switches such as a silence switch, microphone switch, patrol light, etc. while driving.

[Problems that the invention aims to solve] However, it is complicated to perform these various switch operations while driving, and especially when
In the case of wheeled vehicles, there were problems such as the risk of compromising safety.

The purpose of this invention is to solve the above-mentioned problems of the conventional system and to provide an electronic siren loudspeaker system that does not require complicated switch operations.

[Means for Solving the Problems] In order to achieve the above object, this invention includes a bone conduction microphone, a voice recognition device connected to the bone conduction microphone, and a voice recognition device operated by the output of the voice recognition device. an electronic siren; a speech synthesis device controlled by the output of the speech recognition device;
The apparatus includes an output device that amplifies and generates the output of the electronic siren and the voice synthesizer.

[Operation] By adopting the above-mentioned means, this invention can generate an electronic siren sound and generate a voice synthesis output just by inputting voice to the bone conduction microphone.

[Example] Hereinafter, an example of this invention shown in the drawings will be described.

The figure shows an embodiment of this invention, in which 1 is a bone conduction microphone that is installed in the helmet of a motorcycle driver, 2 is a voice recognition switch, and 3 is a bone conduction microphone that is attached to the bone conduction microphone 1 when the voice recognition switch 2 is ON. The voice recognition device 4 inputs the collected voice signal and discriminates and recognizes the content, and when the voice recognition device 3 recognizes a voice signal such as "siren", it starts operating by its output,
Further, when the voice recognition device 3 recognizes, for example, a voice signal such as “stop”, an electronic siren 5 is provided with a memory (ROM) and a high frequency correction circuit, and 5 is equipped with a memory (ROM) and a high frequency correction circuit. ” is recognized, and the output is stored in memory (ROM). For example, “Car in front, please move to the left and stop.”
For example, when the voice recognition device 3 recognizes a voice signal such as “Hosei”, the voice recognition device 3 uses the output to perform high-frequency correction on the voice signal from the bone conduction microphone 1 that the voice recognition device 3 subsequently recognizes. a voice synthesizer that performs high-frequency correction processing in real time in a circuit and outputs it; reference numeral 6 is a mixing amplifier that mixes and amplifies the output of the electronic siren 4 and the output of the voice synthesizer 5 as necessary;
Reference numeral 7 denotes a speaker that converts the output of the mixing amplifier 6 into sound and generates it.

In the electronic siren loudspeaker system described above, for example, when a motorcycle driver wearing a helmet simply says "siren", the electronic siren 4 starts operating and the siren sound is emitted from the speaker 7, and the siren sound is emitted from the speaker 7. Just by saying this, the electronic siren 4 stops operating and the generation of the siren sound stops. Furthermore, when you say "stop," with a normal microphone, this sound is drowned out by the siren sound, making it difficult to recognize, but since bone conduction microphone 1 is used, the effect of sound pressure caused by the siren sound is eliminated. You can easily recognize the sound "stop" without hearing it. In addition, by simply saying "Tomare", a message saying "Car in front, please move to the left and stop" is generated from the speaker 7, and in addition to this, a message is generated from the speaker 7, which is stored in the memory (ROM) of the speech synthesizer 5 in advance. A message can be read from the memory (ROM) and generated from the speaker 7 by simply saying the corresponding keyword.
Also, if you want to generate words other than the message stored in the memory (ROM) of the speech synthesizer 5 from the speaker 7, first say "Hosei" and then say the desired content in words. , the contents are generated from the speaker 7. Moreover, due to its nature, the bone conduction microphone 1 has few harmonic components in the voice, resulting in a sound similar to a cold voice, but instead of generating this directly from the speaker 7, the voice synthesizer 5 performs high-frequency correction. Since the circuit performs high-frequency correction processing in real time and the mixing amplifier 6 amplifies the sound, the sound generated from the speaker 7 has improved clarity and is easy to hear. Furthermore, the output of the electronic siren 4 and the voice synthesizer 5
The output can also be sent wirelessly to an output device, making it cordless.

[Effects of the invention] Since this invention is configured as described above, it is possible to generate an electronic siren sound and generate a voice synthesis output simply by inputting voice to the bone conduction microphone, which eliminates the complicated It is highly safe, especially when applied to two-wheeled vehicles such as motorcycle motorcycles, as it does not require any switch operations, and does not generate noise such as wind noise or howling, and the bone conduction microphone can be easily installed inside a helmet. Therefore, the microphone does not need to be waterproof, and if the signal is transmitted wirelessly between the electronic siren, voice synthesizer, and output device, it becomes cordless and eliminates the danger caused by the cord when a two-wheeled vehicle such as a motorcycle falls over. It has excellent effects such as being able to prevent accidents from occurring.
