Portable electronic device

The present invention relates to a portable electronic device, and more particularly to a portable electronic device having a speaker.

With the development of the communication industry, portable electronic devices such as mobile phones, notebook computers, and PDAs have become an indispensable communication tool in people's daily life, and they have maintained a relatively large advancement. Mobile phones are the most typical of mobile phones. In order to meet the different requirements of mobile phones for consumers, there are more and more mobile phones of various styles and functions in the market. Nowadays, the most popular additional functions of mobile phones are multimedia. Playback features, such as mobile phones with MP4. In order to realize such a playback function, a general mobile phone is provided with a speaker for playing an audio signal, and the speaker is generally placed in a speaker.

The conventional speakers are generally made of plastic material. Because the rigidity of the plastic is small, in order to improve the structural strength of the speaker, it is necessary to increase the thickness of the speaker, so that the volume of the speaker is inevitably reduced, thereby affecting the sound quality of the speaker inside the speaker.

In view of the above, it is necessary to provide a portable electronic device having a speaker with improved sound quality.

A portable electronic device includes a casing, a speaker and a speaker. The speaker is disposed on the casing, and the speaker comprises a metal member for accommodating the speaker and a speaker a rubber member formed on a periphery of the metal member for sealing a gap between the speaker and the housing.

Compared with the prior art, the speaker of the portable electronic device is made of metal material, and the speaker made by the plastic material can be appropriately reduced in the case of satisfying the structural strength of the speaker. The thickness of the speaker increases the volume of the speaker, thereby improving the sound quality of the speaker. In addition, the metal member has better flatness than the plastic member, and the rubber member is formed on the periphery of the metal member, so that the sealing between the speaker and the casing can be improved, thereby further improving The sound quality of the speaker.

1 is a perspective exploded view of a portable electronic device according to a preferred embodiment of the present invention; FIG. 2 is a schematic view showing the speaker of the portable electronic device shown in FIG. 1 disposed on a casing thereof; A schematic diagram of the assembly of the portable electronic device.

The speaker of the present invention can be applied to a portable electronic device such as a mobile phone, a personal digital assistant (PDA) or a digital camera. In this embodiment, a speaker for a mobile phone is taken as an example for explanation.

Referring to FIG. 1, the mobile phone 100 includes a speaker 10, a speaker 20 housed in the speaker 10, and a housing 30 for setting the speaker 10.

The speaker 10 includes a metal member 12 and a rubber member 14 mountable to the metal member 12. The metal member 12 may be made of aluminum or an aluminum alloy, and the rubber member 14 may be made of polybutadiene and butyronitrile.

The metal member 12 includes a first surface 121 facing the housing 30 and a second surface 122 opposite the first surface 121. A portion of the first surface 121 is recessed toward the second surface 122 to form a cavity 123. Correspondingly, a protrusion 124 is formed on the second surface 122, and the speaker 10 itself forms a protrusion around the protrusion. The circumference of 124 is 125. The chamber 123 is for accommodating the speaker 20.

A through hole 126 is defined in the two ends of the metal member 12, and the through hole 126 is defined in the peripheral edge 125. The through hole 126 is for engaging with the housing 30. One side of the metal member 12 has a card 127 extending on one side and two sides 128 on the other side. A notch 1272 is defined in the middle of the card 127, and the notch 1272 and the latch 128 are used to engage with the housing 30.

Referring to Figure 2 together, the rubber member 14 has a shape corresponding to the peripheral edge 125 of the metal member 12 that encloses the peripheral edge 125 therein. The rubber member 14 can be separately manufactured and then sleeved on the peripheral edge 125 of the metal member 12, or can be directly formed on the peripheral edge 125 of the metal member 12 by in-mold molding and wrap the peripheral edge 125.

The housing 30 includes a front wall 32 facing the enclosure 10 and a side wall 34 adjacent the surface 32. A recess 322 corresponding to the protrusion 124 of the speaker wall 32 defines a recess 322, and the recess 322 penetrates the sidewall 34 to form a slot bottom wall 3222 and a side wall 34 of the housing 30. Opposite and parallel slot sidewalls 3224. The bottom wall 3322 of the slot is formed with two vertically extending clamping posts 3226. The clamping posts 3226 are oppositely disposed, and the spacing thereof corresponds to the length of the speaker 20, so that the speaker 20 is engaged with the clamping post 3226. between. The slot side wall 3224 defines two card slots 3228, and the card slot 3228 is disposed corresponding to the cassette 128 of the speaker 10.

Two threaded holes 324 are defined in the wall 32. When the speaker 10 is assembled on the housing 30, the threaded holes 324 are respectively aligned with the through holes 126 of the speaker 10 (see FIG. 3).

A hook 342 is protruded from the side wall 34 , and the hook 342 is disposed corresponding to the notch 1272 of the speaker 10 . Referring to FIG. 3 , when the speaker 10 is assembled on the housing 30 , the hook 342 is engaged in the notch 1272 of the speaker 10 .

When the speaker 10 is disposed on the casing 30, the speaker 10 can be attached to the front wall 32 of the casing 30 from above the casing 30. At this time, the speaker 10 is assembled. The through hole 126 is aligned with the threaded hole 324, and the latch 128 of the speaker 10 is engaged in the slot 3228 of the housing 30. The hook 342 of the housing extends into the notch 1272 of the speaker 10; Two screws (not shown) are respectively passed through the through holes 126, and then the screws are respectively screwed into the threaded holes 324, so that the speaker 10 is tightly pressed against the case by adjusting the screws. On the body 30, the speaker 20 is received in the chamber 123 of the metal member 12.

The speaker 10 of the mobile phone 100 is made of metal material. Compared with the speaker 10 originally made of plastic material, the thickness of the speaker 10 can be appropriately reduced in the case of satisfying the structural strength of the speaker 10, thereby improving The volume of the speaker 10 further enhances the sound quality of the speaker 10. In addition, the metal member 12 has a better flatness than the plastic member, and the rubber member 14 is formed on the periphery 125 of the metal member 12, so that the sealing between the speaker 10 and the casing 30 can be improved. Further, the sound quality effect of the speaker 10 is further improved. In addition, since the speaker 10 is made of a metal material, the electromagnetic shielding effect on the speaker 20 can also be achieved.

It can be understood that the rubber member 14 can also be disposed only on the first surface 121 of the metal member 12, and only needs to achieve the effect of sealing the joint between the speaker 10 and the housing 30.

In summary, the present invention complies with the requirements of the invention patent and submits a patent application according to law. However, the above is only a preferred embodiment of the present invention, and the scope of the present invention is not above The equivalents of the embodiments of the present invention are intended to be within the scope of the following claims.
