CN202617330U - Waterproof loudspeaker - Google Patents

Abstract

The utility model discloses a waterproof loudspeaker. The loudspeaker is formed by a box body, a sealing gasket, a waterproof sound passing membrane, a buzzer, a screw and a screw column. The waterproof sound passing membrane is covered on a sounding surface of the loudspeaker. The sealing gasket whose middle part is hollow is used to seal the waterproof sound passing membrane. Usually, the loudspeaker does not possess a waterproof function and can be only used in a dry environment. By using the waterproof loudspeaker of the utility model, sound of the buzzer can be emitted through the waterproof sound passing membrane and simultaneously a waterproof effect is achieved. Tone quality emitted by the loudspeaker itself is not disturbed and the loudspeaker can be used in a wet mine and under a well.

Description

A kind of waterproof loud speaker

Technical field

The utility model relates to a kind of speech audio equipment, particularly a kind of waterproof loud speaker.

Background technology

Mine and personnel in the pit's production safety more and more receives the attention of national departments at different levels, the also increasingly high technicalization of the employed communication Instrument equipment of mine and personnel in the pit in society now.Loud speaker is widely used on numerous mines and personnel in the pit's communication apparatus.From requirement to the loud speaker sounding; General all is only hole to be set on the casing of loud speaker, but the environment of mine and down-hole is very moist, in case there is water to enter into inside loudspeakers; Will make the inside loudspeakers short circuit; Influence the normal use of communication apparatus, serious words can directly cause device damage, can't carry out communication.

The utility model content

The novel purpose of this use is exactly in order to address the above problem, and a kind of waterproof loud speaker is provided, and under the situation of not disturbing the loud speaker sounding, can play waterproof effect.

For realizing above-mentioned purpose, the waterproof loud speaker of the utility model comprises: casing, sealing gasket, waterproof sound passing membrane, buzzer, screw, screw column are formed, and two screw columns are arranged in the casing, and screw can be screwed in the screw column, makes sealing gasket can contact casing fully; The sealing pad is placed on the buzzer, and the parallel and even card of the sounding face of this buzzer is covered with one deck waterproof sound passing membrane.

As the further improvement to technique scheme, the sealing gasket mid portion is an Openworks shape.Before the assembling buzzer, cover one deck waterproof sound passing membrane at the parallel card of its sounding face, sealing gasket mid portion hollow out, the sealing gasket after the hollow out is placed on the buzzer, with water-proof sound-transmitting film phonograph seal buzzer, make sound can send not blocked fully.

The material of waterproof sound passing membrane is a polytetrafluoroethylene.

Beneficial effect: increase after the waterproof sound passing membrane, guaranteed the stable of loud speaker work itself, and in the mine of trickle humidity and subsurface environment the reliability of speaker operation.

The utility model adopts following technical scheme:

1, card covers waterproof sound passing membrane

2, load buzzer

3, sealing gasket is installed

4, the turn-knob screw is to guarantee waterproof

Embodiment

To combine accompanying drawing to doing further explain in the utility model below.

As shown in Figure 1, the utility model waterproof loud speaker comprises casing 1, sealing gasket 4, waterproof sound passing membrane 3, buzzer 2, screw 5, screw column 6.Two screw columns 6 are arranged in the casing 1, and screw 5 can be screwed in the screw column 6, makes sealing gasket 4 can contact casing 1 fully; Sealing pad 4 is placed on the buzzer 2, and the parallel and even card of the sounding face of this buzzer 2 is covered with one deck waterproof sound passing membrane 3.

1, waterproof sound passing membrane that size is identical with buzzer 2 upper surfaces 3 is parallel and cover uniformly on the buzzer 2, and this buzzer 2 is a buzzer commonly used on the market, and it is the waterproof sound passing membrane of polytetrafluoroethylene that waterproof sound passing membrane 3 adopts materials.

2, buzzer 2 is packed in the casing 1, be placed on casing 1 centre position.

3, as shown in Figure 2, in the middle of buzzer and casing 1, to put into the sealing gasket 4 that mid portion is an Openworks shape perpendicular to the angle of buzzer sounding face, sealing gasket 4 contacts waterproof sound passing membrane 3 fully, and waterproof sound passing membrane 3 is sealed on the buzzer 2.

4, review Fig. 1, at screw column 6 places of casing 1, insert two screws 5 and rotation, make screw column 6 contact fully with dividing plate, the firmly casing 1 thereby assurance sealing gasket 4 is tightly fitted is to play complete waterproof effect.
