Abstract

The utility model relates to a novel switch which can make a loudspeaker send out the sound of different volumes, which is composed of a base, a button, a connecting sheet, a small spring, a contact sheet, a sliding frame, a resistance sheet, a big spring and a binding post, wherein the binding post, the resistance sheet, the contact sheet and the connecting sheet are connected in series. The contact sheet is inserted at two ends of the sliding frame which is connected with the button, and by pressing the button with different force, the loudspeaker can send out the sound of different volumes. People's motorcycles, etc., are more environment-friendly.

Description

Novel switched

One, technical field:

The utility model relates to a kind of appliance switch, especially can make loudspeaker send the novel switched of the sound that varies in size.

Two, background technology:

At present, motorcycle etc. spread to huge numbers of families day by day, become our the common vehicles, and are closely bound up with our life.Often, the loudspeaker that will ring unavoidably.But usually platform is not appropriate to the occasion for the sound of loudspeaker: sound seems very big sometimes, as in quiet residential area, especially at night, has alarmed too many people.Sometimes sound has and seems too little, as on the road of noise and excitement, is difficult to allow the other side hear.

Three, summary of the invention:

Can only make loudspeaker send the defective of a big small voice in order to overcome existing horn switch, the utility model provide one novel switched, control loudspeaker with it, can allow loudspeaker according to the needs of different occasions, send the sound that varies in size.

The technical scheme that its technical problem that solves the utility model adopts is: two resistor discs, two contacts, contact pin, button, little spring, balladeur train, big spring, binding post are set in pedestal.Contact is embedded on the balladeur train, and the contact lower end is connected with resistor disc, and the upper end can be connected with contact pin.Balladeur train can slide up and down.Contact pin is embedded in the button lower end.Button, little spring, balladeur train, big spring connect in turn.When button was pressed, contact pin contacted with two contacts, has formed path between two binding posts, i.e. switch closure.When switch just began closure, owing to contact is and the last end in contact of resistor disc, the resistor disc that electric current passes through was longer, and therefore, the resistance in the entire circuit is bigger, and electric current is less, so the sound of loudspeaker is less.Sound is big more if desired, can continue to press button downwards, and balladeur train and contact can glide thereupon, and the resistor disc that electric current passes through shortens, the resistance decreasing in the entire circuit, and electrorheological is big, and therefore, it is big that the sound of loudspeaker becomes thereupon.Otherwise, if want sound to diminish, can be button pine, under the effect of big spring, balladeur train and contact can with on sliding, the resistor disc that electric current passes through is elongated, it is big that the resistance in the entire circuit becomes, electric current diminishes, therefore, the sound of loudspeaker diminishes thereupon.After button was released, under the effect of little spring, contact pin, contact had separately formed and have opened circuit, be i.e. switch opens.

Of the present utility model useful be can control the size of speaker sound easily according to concrete condition at that time.The utility model is made simple, and cost is low, and is easy to operate, and effect is obvious, can solve the speaker sound size issue effectively.More environmental protection such as the motorcycle of let us.

Among the figure 1, pedestal 2, button 3, contact pin 4, little spring 5, contact 6, balladeur train 7, resistor disc 8, big spring 9, binding post.

Five, embodiment:

In Fig. 1, binding post (9), resistor disc (7), contact (5), contact pin (3) series connection.

In Fig. 2, button (2) is embedded in pedestal (1) upper end, an end outside, an end is interior, and can slide up and down.Button (2) lower end links to each other with contact pin (3), is connected with balladeur train (6) by little spring (4).A contact (5) in embedding respectively at balladeur train (6) two ends, and contact (5) lower end is connected with resistor disc (7), and the upper end can be connected with contact pin (3).Two resistor discs (7) are embedded on pedestal (1) the two Side wall, and the lower end is connected with two binding posts (9).Balladeur train (6) can slide up and down, and links to each other with big spring (8) below.

Claims

1, novel switchedly is formed by connecting by pedestal (1), button (2), contact pin (3), little spring (4), contact (5), balladeur train (6), resistor disc (7), big spring (8), binding post (9).It is characterized in that: resistor disc (7), contact (5) are linked in sequence, and contact (5) is embedded in balladeur train (6) two ends, and balladeur train (6) is connected with button (2) by little spring (4).
