Description

[0001]
[Technical field to which the invention belongs]
The present invention relates to an audio output mechanism of a portable computer, and in particular, can enlarge a resonance space of a speaker unit, form a suitable audio output mechanism, and improve the sense of reality, sound quality, and high / low bass effect of a portable computer speaker. The present invention relates to a portable computer audio output mechanism.
[0002]
[Prior art and its problems]
Currently, generally accepted portable computers include notebook type computers and flat type computers.
FIG. 1 is an exploded view showing the structure of a conventional portable computer. The portable computer mainly includes a positioning frame 16 ', a cover 12', a base 18 ', and a mother board 17'. Then, the cover 12 'covers the outside of the positioning frame 16', and the positioning frame 16 'is disposed on the base 18'. 17 ′ and other members (not shown) are housed therein.
[0003]
A conventional portable computer audio output mechanism has approximately two speakers 10 ', 10' fixed to a cover 12 'and a plurality of sound guide holes 14' formed in the body of the cover 12 '. The sound generated from the speaker 10 'is diffused outside the body.
[0004]
However, the conventional audio output mechanism design employs a configuration in which the overall efficiency and timbre of the speaker are all affected by the large-sized design, and therefore the main functions of the portable computer are small-sized. It is a major obstacle to the construction, and there is a case where inconsistency occurs in the design of the structure.
In the case of using a portable computer as an example, the product design is required to be light, thin and small, and the speaker 10 ′ must be designed to have a flat configuration.
Therefore, the volume given to the audio box of the speaker is also reduced, and the original function of the speaker is lost.
[0005]
That is, as shown in FIG. 2, in the positional relationship between the conventional speaker 10 ′, the cover 12 ′, and the positioning frame 16 ′, the speaker 10 ′ is fixed to the lower half of the cover 12 ′ by the fixing screw 11 ′. Each of the speakers 10 'has a plurality of open holes 100' and is located in the upper half of the lower half of the speaker 10 'opposite to the positioning frame 16'. Therefore, since the open hole 100 'is closely adjacent to the positioning frame 16', the sound of the speaker 10 'is blocked when emitted through the open hole 100'. In addition, the work efficiency of the speaker 10 'is inferior, and the sound effect of the portable computer may be deteriorated, and in some cases, the sound output effect may be lost.
[0006]
[Purpose of the invention]
The present invention can improve the sound output efficiency of the prior art portable computer, obtain a large sound box space by the improved sound output mechanism, and improve the sound effect quality of the portable computer as a whole. Its primary purpose is to provide an output mechanism.
