Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all embodiments. Based on the embodiments of the utility model.

In the description of the present invention, it is to be understood that the terms "upper", "lower", "front", "rear", "vertical", "horizontal", "inner", "outer", etc. indicate orientations or positional relationships based on those shown in the drawings, and are only for convenience in describing the present invention and simplifying the description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention.

In the present invention, unless otherwise expressly stated or limited, the terms "mounted," "connected," "secured," and the like are to be construed broadly and can, for example, be fixedly connected, detachably connected, or integrally formed; can be mechanically or electrically connected; either directly or indirectly through intervening media, either internally or in any other relationship. The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.

In the present invention, unless otherwise expressly stated or limited, the first feature "on" or "under" the second feature may be directly contacting the first and second features or indirectly contacting the first and second features through an intermediate. Also, a first feature "on," "above," and "over" a second feature may mean that the first feature is directly above or obliquely above the second feature, or that only the first feature is at a higher level than the second feature. A first feature being "under," "below," and "beneath" a second feature may be directly under or obliquely under the first feature, or may simply mean that the first feature is at a lesser elevation than the second feature.

Referring to fig. 1 to 6, there is shown a horn having a waterproof function, including: the base 1 is annular, the upper surface of the base is provided with an abutting plane 11, and the outer edge of the abutting plane 11 is upwards protruded with a clamping strip 12; a bracket 2 fixedly connected with the bottom of the base 1, wherein a chamber (not marked in the figure) for accommodating a sounding component is formed in the bracket 2; the sound film 3 is arranged on the base 1 and comprises a vibration cover part 31 protruding in the middle, and the periphery of the vibration cover part 31 is provided with a pressing plane part 32 used for contacting with the abutting plane 11 on the base 1; the sound film 3 is provided with a hydrophobic nano coating; the horn 4 is sleeved outside the base 1 and the bracket 2, a pressing cylinder 41 is arranged inside the horn 4, and the pressing plane part 32 of the sound membrane 3 is pressed on the contact plane 11 of the base 1 by the end part of the pressing cylinder 41, so that water is prevented from entering the cavity of the bracket 2 from the horn 4.

The hydrophobic nano coating (not shown) arranged on the sound film 3 can adopt a super-hydrophobic nano transparent coating with the publication number of CN104987520B, cannot cause any damage to the outer surface of the sound film 3, and can achieve the effects of water resistance, dust resistance and oil resistance; in addition, the sound film 3 is clamped by the horn 4 and the base 1 together through the pressing plane part 32 arranged on the sound film 3, so that the sealing and the waterproof performance between the horn 4 and the sound film 3 are realized; even if water enters from the end of the horn 4, it cannot enter the chamber in the cradle 2; therefore, the loudspeaker is multi-level waterproof, and the waterproof performance of the loudspeaker is extremely strong.

In some specific embodiments, since the sound diaphragm 3 vibrates continuously, in order to prevent the sound diaphragm 3 from loosening in the clamping between the horn 4 and the base 1, referring to fig. 6, the pressing plane portion 32 of the sound diaphragm 3 extends out of the pressing vertical surface portion 33 in the vertical direction, and the pressing vertical surface portion 33 of the sound diaphragm 3 is pressed on the inner side surface of the card strip 12 by the outer peripheral wall of the pressing cylinder 41. Thus, the pressing vertical surface portion 33 can ensure a sealing and waterproofing property between the press cylinder 41 and the sound diaphragm 3, and can make the sound diaphragm 3 difficult to come out from the clamp between the horn 4 and the base 1. Preferably, in order to further enhance the fixing property of the sound membrane 3 in the clamping between the horn 4 and the base 1, the pressing vertical surface portion 33 of the sound membrane 3 extends outward to form an annular retaining portion 34, and the annular retaining portion 34 is disposed on the upper surface of the clip strip 12. Therefore, the edge of the sound film 3 forms a plurality of bends, and the possibility that the sound film 3 is separated from the horn 4 and the base 1 is eliminated. In the above scheme, the horn 4 is connected with the base 1 in a buckling manner. The connection mode of the common horn can be adopted, and therefore, the details are not described herein.

In the above scheme, the sounding component may be a sounding component commonly used for a common horn, referring to fig. 3 and 5, the sounding component includes a U-iron 5, a magnetic steel 6, a washer 7 and a voice coil 8, which are connected in sequence; the U-iron 5 is connected to the bracket 2 and the voice coil 8 is connected to the diaphragm 3. The U-iron 5 and the bracket 2 are connected by screws 9. The working principle of these sounding components is the prior art, and therefore, they are not described in detail.

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 utility model, 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.
