Abstract

The utility model relates to a multi-tone electronic bell, which is characterized in that a plurality of electronic elements are used to form an amplifying circuit so as to drive an electric loudspeaker or a buzzer to sound different tones, the plurality of electronic elements are installed inside a small plastic box, a plurality of buttons are remained outside the small plastic box, and the smallplastic box is fixed on a handlebar of a bicycle or an electric bicycle. When different buttons are pressed, the electric loudspeaker or the buzzer can sound different tones.

Description

The polyphony electronic bicycle bell

Affiliated technical field

The utility model relates to a kind of polyphony electronic bicycle bell, and it is particularly suitable for bicycle or Electrical Bicycle uses.

Background technology

At present, the employed mechanical type bicycle bell that mostly is on bicycle or the Electrical Bicycle, this bicycle bell sound dullness, and damage easily.

Summary of the invention

For overcoming under the existing situation, employed mechanical type bicycle bell sound dullness on bicycle or the Electrical Bicycle, and the deficiency of damaging easily, the utility model provides a kind of polyphony electronic bicycle bell, and it not only can send several sound, and is not easy to damage.

The technical scheme that its technical matters that solves the utility model adopts is: form the circuit that amplifies with some electronic components, drive dynamic loud-speaker or buzzer phone and send different tones, then these electronic components are put into the small plastic box the inside, and reserve several buttons in the outside of small plastic box, again small plastic box is fixed on the handlebar on bicycle or the Electrical Bicycle, press different buttons, dynamic loud-speaker or buzzer phone will send several different tones.

The beneficial effects of the utility model are can replace the mechanical type bicycle bell to send several different tones with Electronic bell, and be not easy to damage.
