DETAILED DESCRIPTION OF THE INVENTION

At the outset, it should be appreciated that like drawing numbers on different drawing views identify identical, or functionally similar, structural elements of the invention.

While the present invention is described with respect to what is presently considered to be the preferred aspects, it is to be understood that the invention as claimed is not limited to the disclosed aspects.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood to one of ordinary skill in the art to which this invention belongs. It should be appreciated that the term “cover” is synonymous with terms such as “case”, “holder”, “jacket”, etc., and such terms may be used interchangeably as appearing in the specification and claims. Although any methods, devices or materials similar or equivalent to those described herein can be used in the practice or testing of the invention, the preferred methods, devices, and materials are now described.

Adverting now toFIGS. 1 to 9,FIG. 1shows a digital product protective cover with speakerphone, including protective cover main body10, the body further including bottom board11and curved walls110. Each card slot (not depicted) is formed between bottom board11and curved walls110, where each card slot is connected to one other. Each card slot includes at least one amplification mechanism. The amplification mechanism further includes sound inlet21, sound outlet22, and sound tube23, shown inFIG. 3, which connects the sound inlet and the sound outlet. Sound inlet21is located at the bottom of the card slot, which is located against the external speaker of the digital product. Sound outlet22is located on the outer wall of the card slot. Sound inlet21and sound outlet22are staggered in the longitudinal direction of the card slot.

The cross section of sound tube23gradually increases from sound inlet21to sound outlet22. Bottom board11surface is includes reinforced ribs13, each reinforced rib13extends to the internal surface of the card slot around bottom board11.

When used, the frame of digital product fits in the card slot, so that the digital product is surrounded by the protective cover. External card slot sidewalls around the protective cover have a power supply interface, USB interface, and various avoidance gaps for the digital product control buttons. The setting of digital product protective cover is well known in the art.

Referring toFIGS. 1,2, and3, an example embodiment of the digital product protective cover with speakerphone is shown.

In this embodiment, sound inlet21and sound outlet22are located at both ends of the card slot, in particular, the amplification mechanism is set on the right side of the card slot. Sound inlet21is set beneath the upper card slot and sound outlet22is set on the outside wall of the lower card slot. Sound tube23is lays in the card slot. Thus, the sound signal from sound inlet21travels into sound tube23. After transmission, sound tube23sends out the sound signal through sound outlet22, thereby enhancing the sound signal.

Referring toFIGS. 4,5, and6, another embodiment of the digital product protective cover with speakerphone is depicted.

In this embodiment, protective cover main body10to the left and right side of card slot includes an amplification mechanism. Sound inlet21and sound outlet22of each amplification mechanism is located at both ends of the card slot. In particular, sound inlet21is located on top of the card slot which is located against the external speaker of the digital product.

Referring toFIGS. 7,8, and9, another embodiment of the digital product protective cover with speakerphone is shown.

In this embodiment, the upper and lower halves of the card slot symmetrically have two amplification mechanisms. In particular, sound inlet21of each amplification mechanism is located in the middle of the card slot, while sound outlet22is located on one end of the card slot.

The level of the amplification mechanism depends on the level of the external speakerphone. The location of sound inlet21and sound outlet22is based on the position of the external speakerphone. Therefore, the present invention can be applied to various brands and models of digital products in the market.

The present invention for a digital product protective cover with speakerphone includes sound inlet21and sound outlet22, which is staggered in the longitudinal direction of the card slot to extend the sound signal transmission distance in sound tube23. This enhances the amplification effect, thereby improving the user experience. Moreover, bottom board11includes reinforced ribs13, which increases the strength of the protective cover. This increased strength provides greater protection for the digital products housed in the protective cover.

Sound tube23cross section from sound inlet21to sound outlet22gradually increases. The surface of bottom board11has reinforced ribs13, which extend to the internal surface of the card slot. Sound inlet21and sound outlet22is located at both ends of the card slot. The protective cover main body to the left and right side of card slot includes an amplification mechanism. Sound inlet21is located in the middle of the card slot and sound outlet22is located on one end of the card slot. The upper and lower halves symmetrically have two amplification mechanisms.

As mentioned above, the present invention includes a dislocation position setting of sound inlet21and sound outlet22to extend the length of sound tube23. This enhances the amplification effect, and, in turn, improves the user experience.

Technologists in this field can make appropriate changes and deformations according to the above technical solutions and ideas, and all these changes and deformations of the utility model should fall within the scope of the claims.
