Problems solved by technology

Moreover, it is often caused by the waste of game time by continuing the game when the whistle has been blown.
In addition, because hearing-impaired people need to pay attention to the appearance of referees at all times, they cannot give full play to their strengths.

Embodiment approach 1

[0019] figure 1 It is a structural diagram showing the whistle system according to Embodiment 1 of the present invention.

[0020] In the figure, the whistle system of this embodiment includes a whistle 1 and a signal lamp device 2 , the signal lamp device 2 is installed separately from the whistle 1 , and receives the whistle information sent by the whistle 1 and displays it on and off. The whistle 1 includes a mouth 3, a resonant cavity 5 for accommodating a rotating ball 4 such as cork, a sensor 6 for detecting the movement of the rotating ball 4, and a transmitter 7 for sending whistle information.

[0021] figure 2 is a block diagram showing the electrical configuration of the whistle 1.

[0022] In the figure, the transmission device 7 has a configuration including an antenna 8 , a transmission unit 9 , an operation unit 10 , and a microcomputer (microcomputer) 11 . Each part of the transmitting device 7 is connected to the sensor 6 via a bus 12 . The microcomputer ...

Embodiment approach 2

[0034] Figure 5 It is an external view showing the signal light device of the whistle system according to Embodiment 2 of the present invention.

[0035] As shown in the figure, the whistle system according to the present embodiment is provided with a hook 20 on the signal lamp device 2 . By setting the hook 20, it can be hung on the net of volleyball, tennis, badminton or table tennis and used. Figure 6 An example of hanging on the steel wire of the suspension volleyball net 30 is shown. By hanging the signal light device 2, the referee can know that the whistle has been blown without looking at the referee.

[0036] As described above, according to this embodiment, by providing the hook 20 on the signal lamp device 2 and hanging it on an article such as a tennis net, it is possible to know that the whistle has been blown when looking squarely at the opponent.

[0037] In addition, although the hook 20 is provided on the upper surface of the signal lamp device 2 in this ...

Embodiment approach 3

[0039] Figure 7 is a configuration diagram showing a whistle system according to Embodiment 3 of the present invention.

[0040] The whistle system according to the present embodiment has a function of setting the type of whistle information to be transmitted, so that similar whistle systems can be used adjacently without interfering with each other. Especially in large-scale games, games are often played in adjoining multiple courts, and it is likely that the signal light device installed in the adjacent courts will respond when the whistle is blown. According to the whistle system of the present embodiment, by pairing and setting the type of whistle information between a pair of whistle and signal light devices, it is possible to avoid causing a reaction of the signal light devices adjacent to the stadium.

[0041] Such as Figure 7 As shown, the whistle 40 is provided with a switch 41 for setting the type of whistle information, and the type of whistle information sent c...

Abstract

When a whistle (1) is blown, whistle information is created in the whistle. A lamp device (2) receives a radio signal transmitted from the whistle (1), demodulates the whistle information, and performs lamp lighting in accordance with the intensity of the whistle sound based on the whistle information. Thus, it is possible to notify that the whistle has been blown and its intensity through visual perception. Thus, even a person having auditory difficulties can know that the whistle has been blown and can concentrate on the playing at ease.

Description

technical field [0001] The present invention relates to a whistle and whistle notification device used as a notification in sports. Background technique [0002] Conventionally, in various sports such as volleyball, rugby, and soccer, whistles have been used to announce the start, end, and foul of a game. Many known conventional whistles are composed of a mouth, a resonant cavity that accommodates a rotating ball such as cork, and an air supply port. [0003] However, the conventional whistle is to inform players that the whistle is blown by hearing, so there is a problem that it is not suitable for sports such as hearing-impaired people. [0004] That is to say, because the hearing-impaired person cannot or is difficult to hear the whistle, they often fail to hear the whistle and continue the game, and as a result collide with other athletes and are considered dangerous actions. And, also often because also continue to play when whistle has been blown, and cause the waste...
