Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.

In the description of the present invention, unless expressly stated or limited otherwise, the terms "connected," "connected," and "fixed" are to be construed broadly, e.g., as meaning permanently connected, detachably connected, or integral to one another; can be mechanically or electrically connected; either directly or indirectly through intervening media, either internally or in any other relationship. The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.

In the present disclosure, unless expressly stated or limited otherwise, the first feature "on" or "under" the second feature may comprise direct contact between the first and second features, or may comprise contact between the first and second features not directly. Also, the first feature being "on," "above" and "over" the second feature includes the first feature being directly on and obliquely above the second feature, or merely indicating that the first feature is at a higher level than the second feature. A first feature being "under," "below," and "beneath" a second feature includes the first feature being directly under and obliquely below the second feature, or simply meaning that the first feature is at a lesser elevation than the second feature.

In the description of the present embodiment, the terms "upper", "lower", "right", etc. are used in an orientation or positional relationship based on that shown in the drawings only for convenience of description and simplicity of operation, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus, should not be construed as limiting the present invention. Furthermore, the terms "first" and "second" are used only for descriptive purposes to distinguish one from another.

As shown in fig. 1-2, the present invention provides a speaker assembly, which comprises a speaker body 1, a sound gathering cover body 2 and a speaker mask 3. The loudspeaker body 1 is provided with a sounding surface, the sound gathering cover body 2 is of a horn-shaped structure, and the small-opening end of the sound gathering cover body 2 is connected to the edge of the sounding surface of the loudspeaker body 1; the loudspeaker mask 3 covers the large opening end of the sound gathering cover body 2 and is connected with the edge of the large opening end of the sound gathering cover body 2.

The loudspeaker assembly gathers the sound emitted by the loudspeaker body 1 and the sound reflected by the shielding object 5 under the reflection action of the inner side surface of the sound gathering cover body 2 by adding the sound gathering cover body 2 with a horn-shaped structure, and the sound is diffused out from the opening of the sound gathering cover body 2, so that the technical effect that the sound emitted by the loudspeaker body 1 bypasses the shielding object 5 is achieved.

In order to achieve the above technical effects, the structure of the speaker assembly will be described below with reference to the accompanying drawings.

As shown in fig. 1, the sound gathering cover body 2 is a horn-shaped structure, and the sound waves diffused all around can be gathered and then diffused outward from the large opening end of the sound gathering cover body 2 by the horn-shaped structure. In order to enable the sound gathering cover body 2 to have a certain sound wave reflection effect, and meanwhile, the sound gathering cover is convenient to manufacture and saves production cost, the side wall of the sound gathering cover body 2 is of a conical surface structure. In other embodiments, in order to make the sound gathering cover body 2 have better structural strength or more expressive appearance, the side wall of the sound gathering cover body 2 may also be designed to be hyperbolic or other curved type.

In order to improve the reflectivity of the inner surface of the side wall of the sound-gathering cap body 2 and thus improve the energy efficiency, the side wall of the sound-gathering cap body 2 has as good a surface smoothness as possible. For example, if the sound focusing cover body 2 is made of a plastic material, a plasticizer may be added to the production material to improve the surface smoothness of the sound focusing cover body 2. If the sound gathering cover body 2 is made of metal, the smoothness of the surface of the sound gathering cover body 2 can be improved by processing the inner surface of the side wall of the sound gathering cover body 2 through grinding, rolling, polishing, electroplating and other processes. In the present embodiment, the focus cage body 2 is formed by injection molding of plastic in consideration of economical efficiency.

In order to avoid the sound waves from leaking out of the joint of the sound gathering cover body 2 and other structural members to cause sound short circuit, that is, when the air density at the outer side of the joint of the sound gathering cover body 2 and other structural members is high (density is low) and the air density at the inner side is low (density is high), the air at the side with high density enters the side with low density through the gap at the joint, so that the sound waves are mutually counteracted. The acoustic short circuit is frequency dependent, the lower the frequency the more pronounced. Therefore, the joint of the sound gathering cover body 2 and other structural parts is sealed by the sealing foam 4, and the phenomenon that noise is generated by low-frequency sound waves due to sound short circuit can be improved.

As shown in fig. 2, when the utility model discloses the time specifically using, the osculum end of gathering the sound cover body 2 covers the sound producing face of speaker body 1 completely for gather gathering of sound cover body 2 gather together the sound wave characteristics can maximize by the utilization. Adopt sealed bubble cotton 4 to seal at loudspeaker body 1 and gather sound cover body 2 junction, also adopt sealed bubble cotton 4 to seal at gather sound cover body 2 and loudspeaker face guard 3 junction simultaneously to improve the phenomenon that low frequency sound wave produces the noise because of the acoustic short circuit. The sound-collecting cover body 2 also has an edge structure matched with the shelter 5 for sheltering the loudspeaker body 1, namely, the shape of the sound-collecting cover body 2 is adaptively designed according to the shapes of different shelters 5.

It is obvious that the above embodiments of the present invention are only examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. Numerous obvious variations, rearrangements and substitutions will now occur to those skilled in the art without departing from the scope of the invention. And are neither required nor exhaustive of all embodiments. Any modification, equivalent replacement, and improvement made within the spirit and principle of the present invention should be included in the protection scope of the claims of the present invention.
