10701468
The subject matter herein generally relates to miniature electro-acoustic devices, in particular to a mounting assembly and an electronic device having the same.
Portable electronic devices are becoming smaller and smaller, and the requirements for sound quality of such devices are also increasing. The speaker module is an important acoustic component of a portable electronic device, being an energy conversion device for converting electrical signals into sound waves. Electro-acoustic effects are required in the devices. To ensure excellent acoustic performance, separate speaker boxes are used. For good sealing between the sound hole to the exterior and the speaker box, the speaker box assembly needs to be fixed with a precise positioning pressing fixture and multiple screws. Such a manufacturing method is cumbersome in assembly and has a low yield.
Therefore, there is room for improvement within the art.
Implementations of the present technology will now be described, by way of embodiments, with reference to the attached figures.
It will be appreciated that for simplicity and clarity of illustration, where appropriate, reference numerals have been repeated among the different figures to indicate corresponding or analogous elements. In addition, numerous specific details are set forth in order to provide a thorough understanding of the embodiments described herein. However, it will be understood by those of ordinary skill in the art that the embodiments described herein can be practiced without these specific details. In other instances, methods, procedures, and components have not been described in detail so as not to obscure the related relevant feature being described. Also, the description is not to be considered as limiting the scope of the embodiments described herein. The drawings are not necessarily to scale and the proportions of certain parts may be exaggerated to better illustrate details and features of the present disclosure.
The term “comprising,” when utilized, means “including, but not necessarily limited to”; it specifically indicates open-ended inclusion or membership in the so-described combination, group, series, and the like.

Referring to
Specifically, the first cavity portion 111 is made of metal material. The preferred metal material is aluminum. A portion of the housing 100 is made of aluminum to be the first cavity portion 111. The first cavity portion 111 is located at the edge of the electronic device 10 for improving the drop resistance of the electronic device 10. The second cavity portion 112 is made of plastic material. The preferred plastic material is rigid plastic. The second cavity portion 112, in another portion of the housing 100, is also made of the rigid plastic. The second cavity portion 112 is located at the middle of the electronic device 10 for improving the stability of the electronic device 10 and reducing the weight of the electronic device 10, also reducing the cost of the electronic device 10. Further, the rigid plastic may be, but is not limited to, polycarbonate (PC) or acrylonitrile-butadiene-styrene copolymer (ABS).
Furthermore, an elastic member 200 is fixed to an inner side of the first cavity portion 111. A protrusion 1111 protrudes from a top portion of the first cavity portion 111 towards the second cavity portion 112. The protrusion 1111 and a bottom portion of the first cavity portion 111 together form a fixing cavity 1112 in which the elastic member 200 is fixed.
Specifically, as shown in
Furthermore, the top of the outer edge of the second cavity portion 112 away from the elastic member 200 is an arcuate body 1121. The arcuate body 1121 protrudes from the top of the outer edge of the second cavity portion 112 towards the first cavity portion 111 to the middle portion of the outer edge of the second cavity portion 112.
An escaping cavity 1122 is defined on the bottom of the second cavity portion 112. The escaping cavity 1122 faces out from the inside of the chamber 110. Correspondingly, the bottom of the functional box 300 is also provided with an escaping hole (not shown), and the one or more function elements 400 in the functional box 300 pass through the escaping hole to match with the escaping cavity 1122, such that the positions of the function elements 400 can be defined.
One end of the functional box 300 abuts against the elastic member 200 and is fixed in the first cavity portion 111. The other end of the functional box 300 abuts against the end of the chamber 110 away from the elastic member 200 and is fixed in the second cavity portion 112. Thus the functional box 300 is integrally fixed in the chamber 110. The sealing and fixing of the functional components can be achieved by using the elastic member 200 with high repulsive force. The specific process in which the functional box 300 is mounted in the chamber 110 is hereafter described.
When the functional box 300 is to be installed, the functional box 300 is tilted into the chamber 110 such that one end of the functional box 300 is in contact with the arcuate body 1121 of the second cavity portion 112, as shown in
The functional box 300 is pushed towards the first cavity portion 111 and simultaneously pressed to the bottom of the chamber 110. The functional box 300 slides along the arcuate body 1121 of the second cavity portion 112 into the chamber 110, and the elastic member 200 is forced towards the inner side of the first cavity portion 111 under the action of the the functional box 300 to give way to the function members 400, as shown in
When the functional box 300 is fully in place in the chamber 110, the elastic member 200 abuts against the functional box 300 under restoring force. One end of the functional box 300 abuts against the elastic member 200, and the other end of the functional box 300 is in close contact with the inner side of the second cavity portion 112. The elastic member 200 with high repulsive force ensures the firm sealing and stable fixing in place of the functional box 300, as shown in
The functional box 300 of the mounting assembly 20 is fixed in place without screws. The mounting assembly 20 utilizes the strong rebound urge of the elastic member 200 to seal and fix the functional box 300 in the housing 100, greatly simplifying the assembly process, reducing assembly and reworking costs, and improving productivity.
The mounting assembly 20 of the electronic device 10 also carries and protects the function elements 400. The screwless fixing structure of the mounting assembly 20 saves complicated positioning, production line fixtures to press screws, and nuts, etc. in assembly, and reduces the cost of the electronic device 10.
When one of the function elements 400 in the functional box 300 of the mounting assembly 20 is a speaker, the screwless functional box 300 does not need a screw hole, the box 300 has a simple structure and saves space for the sound chamber, and sound quality of the electronic device 10 may be enhanced.
The embodiments shown and described above are only examples. Many such details are found in the relevant art. Therefore, such details are neither shown nor described. Even though numerous characteristics and advantages of the present technology have been set forth in the foregoing description, together with details of the structure and function of the present disclosure, the disclosure is illustrative only, and changes may be made in the details, including in matters of shape, size, and arrangement of the parts within the principles of the present disclosure, up to and including the full extent established by the broad general meaning of the terms used in the claims. It will therefore be appreciated that the embodiments described above may be modified within the scope of the claims.
