Abstract

An improved structure for the whistle sound of an alarm. The surface of the alarm body is provided with a whistle start switch and a whistle type selection key, and a programmable integrated circuit module and a buzzer drive circuit module are arranged inside the alarm body. , buzzer and power source, multiple groups of sound frequency modules for the buzzer can be established inside the programmable integrated circuit module, the user only needs to press the whistle start switch, the buzzer will be activated at a fixed frequency The whistle sounds, and then by switching the selection key of the whistle type, you can switch between long-time equal-interval whistle or short-time equal-interval whistle.

Description

Siren whistle improved structure

This creation is an improved structure of an alarm, especially an improved structure of a whistle of an alarm. By establishing multiple sets of sound frequency modules of the buzzer inside the programmable integrated circuit module, the whistle can be activated by turning on the whistle. The switch emits a whistle at equal intervals.

Referring to FIG. 5 , a conventional traffic baton 20 includes a voice activation button 21 for instant return and a buzzer (not shown) arranged inside, and the buzzer will only emit when the user's finger presses the voice activation button 21 If the hand releases the sound activation button 21, the buzzer will not make a sound; however, when directing traffic, the user not only needs to pay attention to pressing the sound activation button 21, but it is also difficult to maintain a constant sound by pressing at equal intervals In addition, the user also needs to adjust the length of the pressing time according to the current situation, and repeatedly pressing the sound activation button 21 is likely to cause damage and consume more power.

In view of this, the creator has been engaged in the manufacturing, development and design of related products for many years. In view of the above goals, after detailed design and careful evaluation, he finally got a practical creation.

This creation is an improved structure for whistle sound of an alarm, including an alarm body, a whistle start switch and a whistle type selection key on the surface, and a programmable integrated body inside. circuit module, a buzzer driving circuit module, a buzzer and a power source; the buzzer driving circuit module is electrically connected to the buzzer, and the buzzer is electrically connected to the power source; the programmable The programmable integrated circuit module is electrically connected to the whistle sound start switch, the whistle sound type selection key, the buzzer drive circuit module and the power source, and the programmable integrated circuit module internally establishes the buzzer Multiple groups of sound frequency modules, the above sound frequency modules can be switched between long-time equal-interval whistle or short-time equal-interval whistle through the whistle type selection key.

With the above structure, the advantages of the present invention are as follows:

1. Automatic and continuous whistle: only after turning on the whistle start switch, the buzzer will continue to whistle at equal intervals, without repeated manual pressing.

2. Switchable interval time frequency: By switching the type selection key of the whistle, you can adjust the long or short-term frequency of the whistle. The above frequencies all emit whistle at equal intervals, and the difference lies in the duration of the whistle. .

Referring to FIG. 1 and FIG. 2 , the present invention discloses an improved structure for whistle sound of an alarm device, including an alarm device body 10 , a whistle sound activation switch 11 and a whistle sound type selection key 12 on the surface thereof, A programmable integrated circuit module 13 , a buzzer driving circuit module 14 , a buzzer 15 and a power source 16 are arranged inside; the buzzer driving circuit module 14 is electrically connected to the buzzer 15 , the buzzer 15 is electrically connected to the power source 16; the programmable integrated circuit module 13 is electrically connected to the whistle start switch 11, the whistle type selection key 12, the buzzer drive circuit module 14 and The power source 16 and the programmable integrated circuit module 13 create a plurality of sets of sound frequency modules for the buzzer 15 , and the sound frequency modules can be switched through the whistle type selection key 12 for a long time at equal intervals A whistle or a short, equally spaced whistle.

Referring to FIG. 3 in conjunction with FIG. 1 , it is disclosed that the present invention can be applied to long-time equal-interval whistle. After pressing the whistle start switch 11, then pressing the whistle type selection key 12 to switch to the long-time equal-interval whistle, The buzzer 15 will send out long-term whistle sounds at regular intervals. In other words, the buzzer 15 will send out long-time whistle sounds, and the interval time of each whistle sound is equal.

Referring to FIG. 4 in conjunction with FIG. 1 , it is disclosed that the present invention can be applied to short-time equal-interval whistle. When the user presses the whistle start switch 11, then presses the whistle type selection key 12 to switch to short-time equal-interval whistle. sound, the buzzer 15 will send out short-time and equal-interval whistle sound, in other words, the buzzer 15 will send out short-time whistle sound, and the interval time of each whistle sound is equal.

This creation can be applied to a baton, electronic whistle, sprayer or stun stick.

Based on the description of the above-mentioned embodiments, one can fully understand the operation, use and effects of the present creation, but the above-mentioned embodiments are only the preferred embodiments of the present creation, which should not limit the implementation of the present creation. The scope, that is, the simple equivalent changes and modifications made according to the scope of the patent application and the description of the creation, are all within the scope of the creation.
