Description

Electronic device

The present invention relates to an electronic device, and more particularly to an electronic device having an electrostatic speaker.

First, please refer to Fig. 1. Since the front surface of a portable electronic device such as a smart phone or a tablet PC usually has a large display screen, it is usually on the housing on the back of the electronic device. A plurality of openings are provided for allowing sound waves inside the electronic device to transmit sound waves to the outside through the aforementioned openings (as indicated by the direction of the arrows in FIG. 1). However, in view of the fact that a general user operates the electronic device to face the display screen of the electronic device (that is, on the front side of the electronic device), the sound emitted by the speaker is often not clearly heard by the user.

In view of this, how to improve the structural design of the conventional electronic device, so that the sound of the speaker can be effectively transmitted to the front surface of the electronic device becomes an important issue.

An embodiment of the present invention provides an electronic device including a body, a back cover, and an electrostatic speaker. The body has a display surface, and the back cover is coupled to the body and is provided with at least one opening, wherein the body and the back cover A hollow cavity is formed therebetween, and the hollow cavity extends from one side of the body to the display surface. The electrostatic speaker is disposed in the hollow cavity, wherein the acoustic wave signal generated by the electrostatic speaker passes through the opening and exits the electronic device, and is transmitted to the display surface via the hollow cavity.

In an embodiment, an opening is formed at an end of the hollow body, and sound waves emitted by the electrostatic speaker can be output through the opening.

In an embodiment, the electronic device further includes a mesh member, wherein the opening is covered by the mesh member.

In an embodiment, the mesh member and the display surface are adjacent to each other.

In an embodiment, the mesh member is located at an edge of the electronic device.

In an embodiment, the hollow body is substantially L-shaped.

In one embodiment, the electrostatic speaker is attached to an inner side surface of the back cover.

In one embodiment, the opening is disposed on one major surface of the back cover, and the front surface is substantially parallel to the display surface of the body.

In one embodiment, the opening is disposed on one side surface of the back cover, and the side surface is substantially perpendicular to the display surface of the body.

In an embodiment, the electronic device is a smart phone or a tablet.

The above described objects, features, and advantages of the invention will be apparent from the description and appended claims

The electronic device 100 of the embodiment of the present invention is, for example, a smart phone or a tablet computer, and mainly includes a body 10, a back cover 20, and at least one electrostatic speaker (Electrostatic Loudspeaker, In the ESL) 30, the body 10 may include components such as a circuit system, a processing unit, and a display module. The back cover 20 and the body 10 are coupled to each other, and the electrostatic speaker 30 is disposed between the body 10 and the back cover 20. As shown in the second and third figures, the back cover 20 is provided with a plurality of openings 21 through which the sound emitted by the electrostatic speaker 30 can pass through the electronic device 100.

It should be noted that the electrostatic speaker 30 is a slim speaker capable of two-way sounding, that is, the electrostatic speaker 30 can also emit sound waves toward the back side of the electronic device 100, and can also face the electronic device 100. The front is vocal. Referring to FIG. 3, when the body 10 of the electronic device 100 is combined with the back cover 20, an L-shaped hollow cavity S is formed between the two, and the hollow cavity S is formed by one side of the body 10. The display surface 101 extends to the front of the body 10, wherein the electrostatic speaker 30 is housed in the hollow body S and can be attached to the inner side surface of the back cover 20; since the electrostatic speaker 30 has the characteristics of two-way sound, The back side of the electronic device 100 can receive the sound emitted by the electrostatic speaker 30, and the sound wave generated by the electrostatic speaker 30 is also transmitted to the display surface 101 in front of the body 10 via the guiding of the hollow cavity S (eg Figure 3 shows the direction of arrow A).

In addition, it can be seen from FIG. 3 that the aforementioned hollow cavity S is formed between the body 10 and the back cover 20, and an opening is formed at the end of the hollow cavity S, and sound waves emitted from the electrostatic speaker 30 can pass through the aforementioned opening. The front side of the electronic device 100 is output; the opening in FIG. 3 is covered by a gas permeable mesh member M, whereby foreign matter or dust can be prevented from entering the inside of the electronic device 100. Referring to FIG. 4 again, the mesh member M is located at the edge of the electronic device 100, wherein the mesh member M and the display surface 101 of the body 10 are adjacent to each other, thereby transmitting sound waves emitted from the electrostatic speaker 30 to the electrons. The front side of the device 100 is used to enhance the listening experience of the consumer during use.

As described above, by providing the opening 21 in the back cover 20 of the electronic device 100, the sound emitted by the electrostatic speaker 30 can be transmitted not only through the back side of the electronic device 100, but also through the position. a hollow cavity S between the body 10 and the back cover 20, thereby transmitting sound waves emitted by the electrostatic speaker 30 to the front surface (display surface 101) of the electronic device 100; thus, whether the user is on the front side of the electronic device or The sound from the electrostatic speaker 30 can be clearly heard on the back.

It should be understood that the foregoing opening 21 can be disposed not only on the main surface 201 of the back cover 20 (as shown in FIG. 3 ), but also on the side surface 202 of the back cover 20 . The sound waves are emitted from the sides of the electronic device 100 to expand the radiation range of the sound waves, wherein the major surface 201 of the back cover 20 is substantially parallel to the display surface 101 of the body 10, and the side surface 202 of the back cover 20 is substantially perpendicular to the display of the body 10. Face 101.

In summary, the present invention provides an electronic device, which mainly includes a body, a back cover, and at least one electrostatic speaker. An L-shaped hollow cavity is formed between the body and the back cover, and the electrostatic speaker is accommodated. Placed in the hollow cavity. In particular, the sound emitted by the electrostatic speaker can be transmitted not only from the opening in the back cover, but also to the front side of the electronic device via the hollow body, thereby greatly improving the user's sense of hearing. Comfort.

Although the present invention has been disclosed above in the foregoing embodiments, it is not intended to limit the invention. Those skilled in the art having the ordinary skill in the art can make some modifications and refinements without departing from the spirit and scope of the invention. Therefore, the scope of the invention is defined by the scope of the appended claims.
