1. Technical Field
The present invention generally relates to speaker structure and, more particularly, to a receiving structure for a speaker in an electronic device.
2. Description of Related Art
Electronic devices such as mobile phones and notebooks often have a speaker assembled therein, requiring a receiving structure for the speaker inside the electronic device. A typical receiving structure includes a housing defining a cavity. The bottom of the cavity includes a plurality of small apertures through which sound from the speaker is emitted. However, the apertures are not shielded from the outside, and contaminants can enter the electronic device therethrough and generally deteriorate sound quality of the speaker.
Therefore, there is room for improvement within the art.
Many aspects of the disclosure can be better understood with reference to the following drawings. The components in the drawings are not necessarily drawn to scale, the emphasis instead being placed upon clearly illustrating the principles of the disclosure. Moreover, in the drawings, like reference numerals designate corresponding parts throughout the several views.
The exemplary embodiment of a receiving structure for a speaker as disclosed is suitable for an electronic device such as a mobile phone, portable computer, and other devices. Referring to
The housing 10 defines a receiving cavity 12 in the interior surface adjacent to a distal end of the housing 10. The receiving cavity 12 receives the first filter 20 and the second filter 30. The bottom of the receiving cavity 12 includes a sound slot 122 allowing a transmission of the sound from the speaker 50. The housing 10 has two connecting poles 14 protruding from the interior surface and adjacent to the two opposite sides of the housing 10 for fixing the housing 10 to the engaging board 40.
The first and second filters 20, 30 are substantially the same shape and size and securely positioned in the receiving cavity 12. The first filter 20 prevents contaminants from entering the interior of the electronic device. The second filter 30 is the same color as the first filter 20 and defines sound apertures 32 at the center thereof.
The engaging board 40 includes a resisting wall 42 defining an assembly recess 422. The resisting wall 42 covers the receiving cavity 12. The assembly recess 422 receives part of the speaker 50. The bottom surface of the assembly recess 422 has an aperture (not shown) defined therein, the sound surface (not shown) of the speaker 50 attaches to the bottom surface of the assembly recess 422 after the speaker 50 assembled in the assembly recess 422. The engaging board 40 defines connecting holes 44 corresponding to the connecting poles 14 of the housing 10, so that, by engagement of the connecting poles 14 with the connecting holes 44, the engaging board 40 affixes securely to housing 10. The speaker 50 corresponds to the assembly recess 422 of the engaging board 40 and can be assembled therein. The sound from the speaker 50 passes through the aperture of the assembly recess 422 and enters the receiving cavity 12.
Referring further to
Because the sound slot 122 of the housing 10 is shielded by the first filter 20, contaminants are filtered from the outside. Moreover, the second filter 30 having the same color as the first filter 20 is stacked onto the first filter 20. Thus, the thickness of the filter combination is increased, and dust proofing is improved. Furthermore, the sound passes more easily by defining the sound aperture 32 of the second filter 30.
It is to be understood that the first filter 20 and the second filter 30 can be integrally formed as a whole.
It is to be understood that even though numerous characteristics and advantages of the present embodiments have been set forth in the foregoing description, together with details of structures and functions of various embodiments, the disclosure is illustrative only, and changes may be made in detail, especially in matters of shape, size, and arrangement of parts within the principles of the present invention to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
