Description

electronic devices

The present invention relates to an electronic device, and more particularly to an electronic device with a foot pad.

Laptops have speakers for playing audio. These speakers are typically located inside the laptop computer. Because the vibrations produced by the speakers at high volume cannot be felt by the user, their volume is limited. This is particularly noticeable in thin laptops. Furthermore, the sound emitted by speakers located inside the laptop computer reflects off the desktop and reaches the user, resulting in poor sound quality. Furthermore, to protect the speakers from shock, additional shock-absorbing components corresponding to the speakers are typically installed inside the laptop computer, which goes against the current trend of thin and light laptop designs.

The present invention provides an electronic device having a speaker with good performance in terms of volume and sound quality and is conducive to a lightweight and thin design of the electronic device.

The electronic device of the present invention includes a device body, at least one foot pad and at least one speaker. The device body is suitable for being placed on a surface. The foot pad is arranged on the bottom surface of the device body and includes a plurality of rib structures. These rib structures are staggered with each other to form a plurality of pores, and the material of the foot pad includes an elastic material. The foot pad includes a connecting portion and a main body, the connecting portion is connected between the main body and the device body, and the main body is used to contact the surface. The pores include a plurality of first pores and a plurality of second pores, the first pores are located in the connecting portion, and the second pores are located in the main body. The pore density of the first pores is different from the pore density of the second pores, or the opening size of the first pores is different from the opening size of the second pores. The speaker is disposed in the footpad and is covered by the footpad, wherein the sound emitted by the speaker is suitable for being transmitted to the outside of the footpad through at least a portion of the pores of the footpad.

In one embodiment of the present invention, the pore density of the first pores is less than the pore density of the second pores.

In one embodiment of the present invention, the opening size of the first pores is larger than the opening size of the second pores.

In one embodiment of the present invention, the rib widths of the rib structures at the connecting portions are greater than the rib widths of the rib structures at the main portions.

In one embodiment of the present invention, the connecting portion surrounds the main body.

In one embodiment of the present invention, the material of the above-mentioned foot pad includes rubber.

In one embodiment of the present invention, the speaker is at least partially located outside the device body.

In one embodiment of the present invention, the above-mentioned speaker has a sound chamber housing, and the sound chamber housing is integrally connected to the foot pad.

In one embodiment of the present invention, the electronic device further includes a screen, wherein the screen is pivotally connected to the device body.

In one embodiment of the present invention, a wire of the speaker passes through the foot pad and is connected to an electronic component in the device body.

Based on the above, in the electronic device of the present invention, the speaker is placed inside the existing foot pad of the electronic device. As a result, the vibration of the speaker is transmitted directly through the foot pad to the desktop rather than to the device body, thereby increasing the speaker volume. Furthermore, the sound emitted by the speaker can be transmitted directly through the pores of the foot pad to the outside of the foot pad and reach the user without being reflected by the desktop, thereby improving the sound quality of the speaker. Furthermore, the foot pad covering the speaker can serve as a shock-absorbing structure for the speaker, eliminating the need for additional shock-absorbing components corresponding to the speaker within the device body. This facilitates the lightweight design of the electronic device and provides ample space within the device body to increase battery capacity or add other components.

FIG1 is a perspective view of an electronic device according to an embodiment of the present invention. Referring to FIG1 , the electronic device 100 of this embodiment is, for example, a laptop computer and includes a device body 110, a screen 120, and a plurality of foot pads 130. The screen 120 is pivotally connected to the device body 110 and can be opened and closed relative to the device body 110. The foot pads 130 are disposed on the bottom surface 110a of the device body 110.

FIG2 is a partial cross-sectional view of the electronic device of FIG1 . FIG3 is a bottom view of the foot pad of FIG1 . Referring to FIG2 , the device body 110 of this embodiment is suitable for being placed on a surface (such as a desktop 50) as shown in FIG2 and being supported from the desktop 50 by the foot pad 130 . The material of the foot pad 130 includes rubber or other types of elastic materials to provide a cushioning effect between the desktop 50 and the device body 110 . The foot pad 130 of this embodiment has a plurality of pores 130a, 130b as shown in FIG3 . Continuing from the above, the electronic device 100 of this embodiment further includes a speaker 140 as shown in FIG2 . The speaker 140 is disposed within and enclosed by the foot pad 130. A wire 1401 of the speaker 140 passes through the foot pad 130 and connects to corresponding electronic components within the device body 110. The sound S emitted by the speaker 140 is transmitted outside the foot pad 130 through at least some of the apertures 130a and 130b in the foot pad 130.

As described above, in the electronic device 100 of this embodiment, the speaker 140 is disposed within the existing foot pad 130 of the electronic device 100. Consequently, the vibrations of the speaker 140 are transmitted directly through the foot pad 130 to the desktop 50 rather than to the device body 110, thereby enhancing the volume of the speaker 140. Furthermore, the sound emitted by the speaker 140 is transmitted directly through the apertures 130a and 130b of the foot pad 130 to the outside of the foot pad 130 and reach the user without being reflected by the desktop 50, thereby enhancing the sound quality of the speaker 140. Furthermore, the foot pad 130 covering the speaker 140 can serve as a shock-absorbing structure for the speaker 140 , eliminating the need for an additional shock-absorbing component corresponding to the speaker 140 within the device body 110 . This facilitates a lightweight and thin design for the electronic device 100 and provides ample space within the device body 110 for increasing battery capacity or adding other components.

Referring to FIG. 2 , in detail, the lower half of the foot pad 130 of this embodiment protrudes outside the device body 110, thereby partially positioning the speaker 140 within the foot pad 130 outside the device body 110. Consequently, the sound S emitted by the speaker 140 can be smoothly transmitted to the user through the foot pad 130 without being transmitted to the device body 110.

The above-described arrangement of the foot pad 130 and speaker 140 of this embodiment can, for example, reduce 250 Hz vibrations by approximately 80% and increase the maximum volume by approximately 50%. Furthermore, since the sound S emitted by the speaker 140 does not pass through the device body 110 and is not reflected by the tabletop 50, as previously described, the attenuation of the sound S emitted by the speaker 140 during transmission is reduced. Consequently, the required volume can be achieved without requiring high power to drive the speaker 140, thereby achieving power savings.

Furthermore, the foot pad 130 of this embodiment includes a connecting portion 132 and a main portion 134. The connecting portion 132 is integrally connected between the main portion 134 and the device body 110 and surrounds the main portion 134. The main portion 134 is used to contact the desktop 50. The connecting portion 132 is joined to the device body 110 by gluing, hot-melt, or other suitable means, for example, but the present invention is not limited thereto.

On the other hand, the speaker 140 of this embodiment includes a speaker element 142 and a sound chamber housing 144. The speaker element 142 is disposed within the sound chamber housing 144, with the sound chamber housing 144 serving as a resonance chamber. The sound chamber housing 144 is, for example, integrally connected to the main body 134 of the footrest 130. For example, the sound chamber housing 144 and the footrest 130 can be manufactured together using 3D printing technology. However, the present invention is not limited to this. In other embodiments, the sound chamber housing 144 and the footrest 130 can be manufactured separately and assembled together.

As shown in FIG3 , the foot pad 130 of this embodiment includes a plurality of rib structures 1301. These rib structures 1301 intersect with each other to form the pores 130a and 130b of the foot pad 130. The first pores 130a are located in the connecting portion 132, and the second pores 130b are located in the main portion 134. The pore density of the first pores 130a is different from the pore density of the second pores 130b, and/or the opening size of the first pores 130a is different from the opening size of the second pores 130b. For example, as shown in FIG3 , the pore density of the first pores 130a of the foot pad 130 is smaller than the pore density of the second pores 130b of the foot pad 130. It should be noted that the definition of the pore density is, for example, the number of pores per unit area. As shown in FIG3 , the number of first pores 130a in the unit area A1 at the connecting portion 132 is less than the number of second pores 130b in the unit area A2 at the main portion 134, and the pore density of these first pores 130a is less than the pore density of these second pores 130b. On the other hand, in this embodiment, the opening size D1 of the first apertures 130a of the foot pad 130 is larger than the opening size D2 of the second apertures 130b of the foot pad 130. The rib width W1 of the rib structure 1301 of the foot pad 130 at the connection portion 132 is larger than the rib width W2 of the rib structure 1301 at the main portion 134 of the foot pad 130. Consequently, the foot pad 130 is given greater elasticity at the connection portion 132 to effectively absorb vibrations from the speaker 140. Furthermore, the main portion 134 of the foot pad 130 is given greater structural strength to support the desktop 50 without deformation. In other embodiments, the three conditions of pore density, opening size, and rib width of the foot pad in the connecting portion and the main body can be met by one, two, or all three.

In summary, in the electronic device of the present invention, the speaker is placed within the existing footrest of the electronic device. Consequently, the vibrations of the speaker are transmitted directly through the footrest to the desktop rather than to the device body, thereby increasing the speaker volume. Furthermore, the sound emitted by the speaker is transmitted directly through the pores of the footrest to the outside of the footrest and reaches the user without being reflected by the desktop, thereby improving the sound quality of the speaker. Furthermore, the footrest covering the speaker serves as a shock-absorbing structure for the speaker, eliminating the need for additional shock-absorbing components corresponding to the speaker within the device body. This facilitates the lightweight design of the electronic device and provides ample space within the device body to increase battery capacity or add other components.
