Description

Tablet computer simple horn cavity structure

Technical field:

The utility model relates to the technical field of tablet computers, in particular to a simple loudspeaker cavity structure for tablet computers.

Background technique:

A tablet computer, also called a tablet computer, is a small, portable personal computer with a touch screen as the basic input device. It has a touch screen that allows users to work with a stylus or digital pen instead of a traditional keyboard or mouse. Users can use built-in handwriting recognition, an on-screen soft keyboard, speech recognition, or a real keyboard. The development of tablet PC is accompanied by the rapid development of communication technology. As an emerging technology, it is rapidly becoming popular all over the world.

Existing tablet computer speakers generally adopt a simple assembly process. The tablet computer has no sound cavity structure, and the speaker is directly installed on the face shell. Because of the small size of the speaker, the sound from the speaker is relatively harsh, the bass effect is poor, the sound is small, and the effect is poor. However, if an independent sound cavity speaker is used, the price is expensive and the cost is increased.

Utility model content:

The purpose of the utility model is to provide a simple loudspeaker cavity structure for a tablet computer which can improve the sound effect of the loudspeaker and is low in cost in view of the deficiencies in the prior art.

The sound cavity groove is an oval groove.

The sound hole is an oval hole.

The foam cover plate is bonded and fixed on the rear end surface of the sound chamber groove.

The rear end of the face shell is provided with a plurality of sound chamber grooves, and a horn is installed in each sound chamber groove.

One side of the sound chamber groove is provided with a wire passage opening communicating with the inner cavity of the sound chamber groove.

The positions of the sound chamber grooves located on both sides of the wire-passing opening protrude inwardly with clamping plates, and the inner cavity of the sound cavity groove is located on the opposite inner side of the wire-passing opening and also protrudes inwards with clamping plates.

An inward corner of each card board is provided with a bevel.

The middle part of the sound chamber groove is protruded with a boss.

The beneficial effects of the utility model are: the simple horn sound cavity structure of the tablet computer provided by the utility model includes a face shell and a horn, and the sound cavity groove is arranged at the rear end of the face shell, and the rear end surface of the sound cavity groove is covered with a foam cover plate, The speaker is installed in the sound chamber groove, and the position corresponding to the speaker on the foam cover plate is provided with a sound outlet for the sound of the speaker. The combination of the foam cover plate and the sound cavity groove forms a resonance cavity, which can improve the bass effect of the speaker , large volume, good sound effect, simple structure, easy manufacture, and low cost to solve the problem of poor sound quality of small-sized speakers used in traditional tablet computers.
