Detailed Description

In order that the above objects, features and advantages of the present disclosure may be more clearly understood, aspects of the present disclosure will be further described below. It should be noted that the embodiments and features of the embodiments of the present disclosure may be combined with each other without conflict.

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present disclosure, but the present disclosure may be practiced in other ways than those described herein; it is to be understood that the embodiments disclosed in the specification are only a few embodiments of the present disclosure, and not all embodiments.

It is noted that, in this document, relational terms such as "first seal" and "second seal", and the like, are used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. Also, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising a … …" does not exclude the presence of another identical element in a process, method, article, or apparatus that comprises the element.

The cell-phone mainly provides the function of putting outward with loudspeaker, but loudspeaker sound can not directly transmit out, need realize the spread of sound through preceding shell and backshell from the sound chamber export of loudspeaker, all set up on preceding shell and backshell and put out the sound hole based on this, preceding shell and backshell are upper and lower structure, the play sound direction of loudspeaker is the horizontal direction of preceding shell and backshell, just will set up vertical play sound orifice plate based on the one end of preceding shell and backshell, in order to form a complete loudspeaker shell structure, in order to let sound more concentrated, consequently, will go out sound orifice plate with loudspeaker sound chamber sound mouth and preceding shell, preceding shell goes out sound orifice plate and backshell and goes out the sound orifice plate between use sealed bubble cotton to seal up the ability, in order to satisfy the tone quality effect, when specifically using sealed bubble cotton to seal, need divide into two steps and assemble sealed, assembly efficiency is low, and paste the sealed bubble cotton deviation that often has and make sealed the sealed effect worsen, thereby influence sound quality.

Based on this, this disclosed embodiment provides a cell-phone loudspeaker goes out sound hole seal structure, sets two sealing members to a seal structure, only needs once to operate to accomplish pasting of above-mentioned position during the assembly to fix a position accurate, raise the efficiency at pasting the in-process.

The sealing structure of sound outlet hole of the mobile phone speaker is explained in detail by the following specific embodiment:

referring to fig. 1 to 5, the present disclosure provides a sealing structure for a sound outlet hole of a mobile phone speaker, which includes a sealing portion 1 assembled on a sound outlet hole plate of a front case and a limiting portion 2 for realizing accurate positioning.

The sealing part 1 includes a first sealing element 11, a second sealing element 12 and a flexible connecting element 13, the sealing element 11 in this embodiment may be an annular sealing foam, or a sealing rubber ring and other structures capable of achieving sealing, in order to be thinner and lighter when used on a mobile phone, the first sealing element 11 in this disclosure specifically selects an annular sealing foam, further, the shape of the sealing foam may be annular, or the annular shape may be any shape as needed and is only a preferred mode of this embodiment without limitation, for example, when the speaker sound cavity opening is a structure with multiple sound outlet holes, the first sealing element 11 may be configured to have a porous plate-shaped structure on its body that is adapted to the multiple sound outlet holes of the speaker sound cavity, and specifically, the premise is that sound outlet and the periphery of the sound outlet holes are sealed; the second sealing member in this implementation is the same with first sealing member nature, because of second sealing member 12 is more close to the external world, consequently the second sealing member can select dustproof sealed bubble cotton of preventing, prevents that particulate matters such as external dust from getting into in the loudspeaker.

In order to simplify the assembly process, improve assembly efficiency, first sealing member 11 and second sealing member 12 interval of this disclosure set up on the flexible member connecting piece, form a holistic seal structure, wherein flexible connecting piece 13 can select for use from type membrane or have certain elastic rubber circle etc. certainly need make first sealing member 11 and the removable dismantlement of second sealing member 12 be connected with this seal structure when selecting from the outer seal structure of type membrane.

This spacing portion 2 of disclosure sets up in the front the shell goes out the one side that the sound orifice plate is close to the sound chamber, and spacing portion 2 is used for restricting the position of first sealing member 11 in the front on the shell goes out the sound orifice plate to satisfy first sealing member 11 in the front accurate location on the shell goes out the sound orifice plate, improve sealed effect. Further, the limiting part 2 may be a front housing sound outlet plate bottom provided with a limiting groove or a stopper, and the like, specifically the setting mode of the present disclosure is that the limiting part 3 is divided into two limiting parts 21, the limiting parts 21 are right triangle, the two limiting parts 21 are opposite in the sound outlet plate, and the limiting parts 21 are arranged at the included angle between the front housing sound outlet plate and the front housing, a limiting space is formed between the two limiting parts 21, a further side surface of the first sealing part 11 far away from the second sealing part 12 is matched with the limiting space in a similar shape, and after the first sealing part 11 is placed in the limiting space, the sound outlet holes of each part are just aligned with the hollow part of the first sealing part 11 and are sealed all around. In an exemplary specific use, the first sealing element 11 is inserted into the point aligning space, and is adhered to the front shell sound outlet plate, and the second sealing element 12 is adhered to the other side of the front shell sound outlet plate through the flexible connecting element 13; it should be noted that the flexible connecting element 13 is preferably sized and long enough to enable the second sealing element 12 to reach the opposite corresponding position after the first sealing element 11 is attached. After the sealing elements on the two sides are completely adhered, the flexible connecting piece 13 (in this embodiment, a release film) is removed.

Furthermore, the flexible connecting piece 13 is a rectangular release film, and the width of the flexible connecting piece 13 is equal to the width of the first sealing element 11 and the second sealing element 12, so as to prevent the assembly from being affected by torsional deformation during the installation of the sealing part 2.

The present disclosure further provides a mobile phone speaker, which includes the above mobile phone speaker sound outlet hole sealing structure.

The previous description is only for the purpose of describing particular embodiments of the present disclosure, so as to enable those skilled in the art to understand or implement the present disclosure. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the disclosure. Thus, the present disclosure is not intended to be limited to the embodiments shown herein but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
