Electronic whistle amplification system

The invention relates to an electronic whistle amplification system, in particular to a sound amplification system capable of wirelessly connecting an electronic whistle to a speaker device.

According to the whistle, the whistle has the structural characteristics that can easily make sounds. Therefore, it has been widely used in various occasions such as warnings and reminders (such as sports competitions). In recent years, people have committed frequent crimes and frequent natural disasters. The whistle is a kind of warning and rescue tool that is convenient to carry, easy to use and low in cost. However, in an increasingly complex environment, various sources of sound are extremely extensive and complex, and a simple (or irregular) whistle is hard to attract attention.

The known electronic whistle, such as the Republic of China New Patent Bulletin No. M245574 "Multi-function electronic whistle", is an electronic whistle consisting of a body, a segment selection switch, a push button switch and a buzzer, wherein the electronic device inside the body Including IC, resistors, capacitors, inductors and transistors and other electronic components, it is convenient to control the length of the whistle by pressing the button switch, and it is safe, hygienic, easy to carry, can emit lighting and continuous operation.

The above-mentioned patent pre-existing cases still have some shortcomings to be improved. The main reason is that the volume of warning sounds in the patent case is limited, so the large-scale competitions (such as the World Cup soccer game will have tens of thousands of viewers and more than 100,000 viewers). When the entrants and the audience in the grandstand area are far away from the referee or the environment is noisy, it is not easy to clearly hear the whistle of the referee. This will not be easy for the entrant to react immediately, and will affect the progress of the competition. I can't grasp the game immediately.

Accordingly, in order to improve the above-mentioned deficiencies and improvements, the inventors have devised to develop an electronic whistle for connecting a broadcast system, the broadcast system including a main control module, and connecting the main a second transmission interface and a speaker of the control module, the electronic whistle comprising: a processing unit; an input module connected to the processing unit for inputting an operation signal; and a sound unit connected to the processing unit; a processing interface is connected to the processing unit; thereby, the processing unit generates a control signal according to the operation signal, to control the sound unit to generate a first warning sound effect, and transmit the first transmission interface to the broadcast system by using the first transmission interface The second transmission interface causes the main control module to control the speaker to generate a second warning sound according to the control signal.

Further, the input module includes a button.

Further, the input module comprises a mouthpiece, a spring piece and a pressure sensor, the spring piece corresponding to the mouthpiece, the pressure sensor is connected to the processing unit, and a gas enters the mouthpiece to cause the spring piece to trigger the pressure a sensor that transmits the aforementioned operational signal to the processing unit.

Further, the input module is a pneumatic sensing module for sensing the operation signal when a pressure is greater than a preset preset value.

Further, the broadcast system further includes a storage unit connected to the main control module, the storage unit stores an audio data, and the audio data corresponds to the first warning sound, so that the main control module controls the speaker generated according to the audio data. The second alert sound is substantially the same as the first alert sound.

Further, a positioning unit is further connected to the processing unit. When the operation signal is generated, the positioning unit obtains a current coordinate information for the processing unit to send the current coordinate information to the broadcast system.

The invention further provides an electronic whistle sound amplification system, comprising: a broadcast system, comprising a main control module, and a speaker connected to the main control module; and the electronic whistle, the wireless signal connection The broadcast system is configured to input the foregoing operation signal to generate the first warning sound effect, and enable the speaker of the broadcast system to generate the second warning sound effect.

According to the above technical features, the following effects can be achieved:

1. The invention can be applied to a large sports field. When the referee blows the whistle or presses the whistle, the individual speakers on the side of the control field can be simultaneously transmitted to give a warning sound, so that the entrants, the audience in the viewing area, etc. are far away from the referee or the environment is noisy. Under the influence of other factors, the referee’s whistle can still be clearly heard.

2. The invention can also be applied to the female user's night return, and can also be used as a broadcasting system for each speaker on the way home. When the female user whistle or press the whistle, the surrounding speaker can be simultaneously alerted. Self-defense protects itself.
