Description

Electronic device with receiver

The present invention relates to an electronic device having a receiver, and more particularly to an electronic device using a special configuration of a receiver.

With the rapid development of the communication industry, the use of various portable electronic devices such as mobile phones and personal digital assistants (PDAs) has become more and more popular. More and more consumers are no longer satisfied with the simple functions of using only portable electronic devices to answer calls, send and receive information, and more hope that these portable electronic devices have more diverse multimedia functions, such as playing MP3 music files. Or video files and so on. In order to achieve the desired sound effect when implementing the audio or video file playback function, the portable electronic device needs to be equipped with a corresponding sound emitting mechanism.

Referring to FIG. 1 , a conventional electronic device 10 includes a housing 12 and a protective panel 14 mounted on the upper half of the housing 12 , wherein the housing 12 further includes a display mounting port 15 and a plurality of The sound ports 16, 18 and a sound chamber (not shown) disposed in the casing 12 and communicating with the sound outlets 16, 18, wherein the sound chamber further comprises a receiver (not shown), the receiver The sound can be transmitted to the outside through the sound outlets 16, 18.

Obviously, in the conventional electronic device 10, if a larger volume is desired, a larger or larger number of sound outlets 16, 18 need to be opened on the shield 14. However, since the sound outlets 16, 18 are provided on the shield 14 in an opening manner, they are opened. When the sound ports 16 and 18 are provided, the sound outlets 16 and 18 are also required to be fitted to the casing 12 to open corresponding openings. When the number of sound outlets on the shield 14 is large or the area is large, the structural strength of the shield 14 may be lowered, resulting in the shield 14 being easily damaged.

In view of the above, it is necessary to provide an electronic device that can reduce the area and number of sound holes in the casing and the protective plate while maintaining a certain sound quality.

An electronic device includes a protective plate, a casing, a receiver, and a main board. The shielding plate is engaged with an upper surface of the casing, and the shielding plate defines a main sound outlet, and the casing is opened. Corresponding to one of the first openings of the main sound outlet, the housing and the main board are mutually joined to each other to form a cavity for receiving the receiver. The receiver is mounted on the main board obliquely with respect to the main sound outlet, so that the main sound outlet and the receiver partially overlap, so that at least one sound outlet is formed on the main sound outlet.

Compared with the prior art, the electronic device provided by the present invention overlaps the main sound outlet of the receiver and the protective plate on the protective plate, so that only one sound outlet and one corresponding need to be opened on the protective plate and the shell. The opening can achieve a certain sound quality effect, not only the process is simple, but also the structural strength is high.

Referring to FIG. 2, an electronic device 20 of the preferred embodiment of the present invention is a mobile phone, which includes a protective board 24, a housing 22, a receiver 28, a display 25, and a main board 32.

The main board 32 is a substantially rectangular circuit board for mounting the display 25, the receiver 28, and other electronic components necessary for the electronic device.

The receiver 28 includes a speaker 281 and a frame 282 for receiving the speaker 281. The frame 282 is substantially rectangular. The speaker 281 is fixedly disposed at the center of the frame 282. The speaker 281 includes a front sound-emitting area 281a, a substantially elliptical foam 281b, and a side wall 281c around the front sound-emitting area 281b, wherein the foam 281b is disposed on the front sound-emitting area 281a. In order to improve the sound-emitting effect, the back surface of the speaker 281 is also provided with a structure (not shown) which is identical to the front sound-emitting area 281a, and the sound received by the receiver 28 can pass through the front sound-emitting area 281a. And the subsequent sounding area is transmitted outward.

The display 25 is a conventional display mounted on the main board 32 for displaying necessary image information.

The housing 22 is substantially the same size as the main board 32 for engaging the main board 32 to form a cavity (not shown) for receiving the receiver 28 and the display 25. A first opening 22a and a second opening 22b are formed in the housing 22 at a position opposite to the receiver 28 and the display 25, wherein the first opening 22a is substantially equal in size to the receiver 28. And the size of the second opening 22b is substantially equal to the size of the display 25.

The protective plate 24 is a substantially rectangular acrylic plate that is engaged with the peripheral edge 22c of an upper surface of the casing 22 to prevent a user or a substance such as dust from directly contacting the display 25 and the receiver 28. In order to facilitate the transmission of the sound emitted by the receiver 28 to the outside, a main sound outlet 24a is defined in the shield 24. The main sound outlet 24a has a substantially strip shape, and the length of the main sound outlet 24a is substantially equal to the length of the receiver 28, and the width thereof is smaller than the width of the frame 282, which is advantageous for increasing the structural strength of the shield 24. .

FIG. 3 is a partially assembled view of the electronic device 20, wherein the display 25 and the receiver 28 are mounted on the main board 32. The housing 22 has been engaged with the main board 32, and only the protective board 24 is not assembled to The housing 22 is on. As shown in the figure, the A line shows the corresponding position of the main sound outlet 24a on the shield 24, and the receiver 28 is obliquely mounted on the main board 32, the long axis x and the main sound outlet 24a ( A line A) has a first angle θ. In this embodiment, the first angle θ is between 5 and 35 degrees.

Please refer to FIG. 4 , which is an enlarged schematic view of the electronic device 20 shown in FIG. 3 after the shield 24 is assembled. In order to more clearly show the oblique configuration of the above-mentioned receiver 28, the outline of the receiver 28 is indicated by a broken line in particular. As shown, the center of the front sound exit area 281a is substantially aligned with the center of the main sound outlet 24a, and the main sound outlet 24a is the main sound outlet of the electronic device 20.

As can also be seen from Fig. 4, the long axis x of the receiver 28 and the main sound output port 24a have the first angle θ. In addition, since the length of the main sound outlet 24a is substantially the same as the length of the receiver 28, the receiver 28 can be disposed at the opposite ends of the main sound outlet 24a by obliquely arranging the receiver 28 with respect to the main sound outlet 24a. The portion not blocked by the frame 282 forms two secondary sound outlets 36, and the sound emitted from the sound-emitting region after the speaker 281 can be transmitted to the outside through the sound outlet 36, further improving the overall sound quality.

The electronic device of the present invention has the advantage that only one area needs to be opened on the casing and the protective plate of the electronic device by means of arranging the receiver 28 obliquely with respect to the main sound outlet 24a of the protective plate 24. The smaller opening can obtain a better sound quality effect, and can effectively reduce the area of the openings, which is advantageous for increasing the structural strength of the protective plate 24 and simplifying the overall process.

In summary, the present invention complies with the requirements of the invention patent and submits a patent application according to law. However, the above are only the preferred embodiments of the present invention, and the scope of the present invention is not limited to the above-described embodiments, and equivalent modifications or variations made by those skilled in the art in light of the spirit of the present invention are It should be covered by the following patent application.
