Description
Technical Field
The invention relates to the field of electric appliances, in particular to a sound box.
Background
Some outdoor sound boxes are often arranged in parks, so that beautiful music can be played to relieve mood when people walk around, or notification can be played.
However, the loudspeaker box is used in the open air, water is often fed in the loudspeaker box in rainy days, so that elements are aged, and certain potential safety hazards exist; if the sound box is completely sealed in the waterproof shell, the sound quality is still stuffy, and the use effect is affected.
Disclosure of Invention
In view of the above problems, an object of the present invention is to provide an outdoor rainproof speaker capable of preventing water from entering in rainy days without affecting the sound quality in daily use.
The technical scheme adopted by the invention for realizing the technical purpose is as follows: the outdoor rainproof sound box comprises a base, wherein a cylindrical cavity with an upward vertical opening is formed in the center of the base, and a loudspeaker facing upwards is arranged at the bottom of the cylindrical cavity; a hollow inverted cone is arranged right above the cylindrical cavity, an opening is formed in the upper bottom surface of the hollow inverted cone to form a water accumulation cavity inside the hollow inverted cone, and the hollow inverted cone has a smooth outer surface to form good reflection on sound waves; a spring is arranged in the cylindrical cavity and supports the hollow inverted cone through the spring, so that the hollow inverted cone is supported above the cylindrical cavity in a natural state, and the side wall of the hollow inverted cone faces the outside; when the water accumulation cavity is full of water, the hollow inverted cone overcomes the elastic force of the spring and sinks into the cylindrical cavity; and a circle of annular cover plate is formed on the periphery of the upper bottom of the hollow inverted cone, and when the hollow inverted cone is completely sunk into the cylindrical cavity, the annular cover plate completely covers the upper opening of the cylindrical cavity.
Preferably, the outer edge of the annular cover plate extends out of the outer side wall of the base, so that rainwater on the annular cover plate cannot flow to the upper surface of the base; further, the lower surface of the annular cover plate is formed by a rubber layer so as to further improve the sealing property between the annular cover plate and the upper surface of the base; the upper surface of the annular cover plate forms a slope surface with a high middle part and a low periphery so as to facilitate the rainwater to slide outwards.
Preferably, the balloon is connected above the hollow reverse cone through an elastic component to attract children to flap and play, so that the hollow reverse cone shakes, the reflection angle and the propagation path of sound waves are changed, a fluctuating sound effect is formed, and the interest is improved to a large extent. Further, the elastic member is a thin tubular spring.
Preferably, the cone angle of the hollow inverted cone is 80 ° to 90 °, so that the sound wave can be transmitted outwards relatively horizontally, and a good transmission effect is obtained.
The invention has the beneficial effects that: when the outdoor rainproof sound box does not rain, the hollow inverted cone is supported by the spring and is positioned above the cylindrical cavity, and at the moment, the loudspeaker upwards emits sound waves when working and transmits the sound waves to the outside after being reflected by the outer surface of the hollow inverted cone, so that people who play can enjoy beautiful music; in rainy days, the water accumulation cavity of the hollow inverted cone of the sound box is gradually filled with rainwater, so that the rainwater overcomes the elastic force of the spring below under the action of gravity, and then the rainwater sinks into the cylindrical cavity, and the annular cover plate covers the upper opening of the cylindrical cavity, so that electronic elements such as a loudspeaker and the like in the cylindrical cavity cannot be influenced by the rainwater to cause faults.
Drawings
Fig. 1 is a schematic view of an embodiment of the outdoor rainproof sound box in sunny days.
Fig. 2 is a schematic view of the embodiment shown in fig. 1 during rainy days.
Detailed Description
The invention is further illustrated with reference to the following figures and examples:
in the embodiment shown in fig. 1 and 2, the outdoor rainproof sound box comprises a base 1, wherein the base 1 is provided with a cylindrical cavity 10 which is opened vertically upwards in the center, and the bottom of the cylindrical cavity 10 is provided with a loudspeaker 2 which faces upwards; a hollow reverse cone 3 is arranged right above the cylindrical cavity 10, an opening is formed on the upper bottom surface of the hollow reverse cone 3 so as to form a water accumulation cavity 30 inside the hollow reverse cone 3, and the hollow reverse cone 3 has a smooth outer surface so as to form good reflection to sound waves; a spring 4 is arranged in the cylindrical cavity 10, and the hollow inverted cone 3 is supported by the spring 4, so that the hollow inverted cone 3 is supported above the cylindrical cavity 10 in a natural state, and the side wall of the hollow inverted cone 3 faces the outside; when the water accumulation cavity 30 is full of water, the hollow inverted cone 3 overcomes the elastic force of the spring 4 and sinks into the cylindrical cavity 10; the periphery of the upper bottom of the hollow inverted cone 3 forms a ring-shaped cover plate 5, and when the hollow inverted cone 3 is completely sunk into the cylindrical cavity 10, the ring-shaped cover plate 5 completely covers the upper opening of the cylindrical cavity 10.
In addition, the outer edge of the annular cover plate 5 extends out of the outer side wall of the base 1, so that rainwater on the annular cover plate 5 cannot flow to the upper surface of the base 1; further, the lower surface of the annular cover plate 5 is formed by a rubber layer 51 to further improve the sealing performance between the annular cover plate and the upper surface of the base 1; the upper surface of the annular cover plate 5 forms a slope surface with a high middle part and a low periphery so as to facilitate the rainwater to slide outwards.
In addition, the balloon 7 is connected above the hollow reverse cone 3 through the elastic component 6 so as to attract children to flap and play, so that the hollow reverse cone 3 shakes, the reflection angle and the propagation path of sound waves are changed, a fluctuating sound effect is formed, and the interest is improved to a large extent. Further, the elastic member 6 is a thin tubular spring.
In addition, the cone angle of the hollow inverted cone 3 is 80-90 degrees, so that the sound wave can be spread outwards horizontally, and a good spreading effect is further obtained.
When the outdoor rainproof sound box does not rain, the hollow inverted cone 3 is supported by the spring 4 and is positioned above the cylindrical cavity 10, and at the moment, the loudspeaker 2 upwards emits sound waves when working, and the sound waves are reflected by the outer surface of the hollow inverted cone 3 and then are transmitted to the outside, so that people who play can enjoy beautiful music; in rainy days, the water accumulation cavity 30 of the hollow inverted cone 3 of the sound box is gradually filled with rainwater, so that the rainwater overcomes the elasticity of the spring 4 below under the action of gravity, and then the rainwater sinks into the cylindrical cavity 10, and the annular cover plate 5 covers the upper opening of the cylindrical cavity 10, so that electronic elements such as the loudspeaker 2 and the like in the cylindrical cavity 10 cannot be influenced by the rainwater to cause faults.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
