Description
Technical field
But the electronic installation of the relevant a kind of play sound effect of the present invention, particularly relevant a kind of notebook computer that improves the audio function that has.
Background technology
In general, present notebook computer all disposes loudspeaker with output sound, and loudspeaker normally are arranged on the main frame of notebook computer.More detailed, the main frame of notebook computer normally is made of a upper shell and a lower house, and loudspeaker are to be arranged on the upper shell, and also are provided with a printed circuit board (PCB) (PCB) between upper shell and lower house.Because the lower end of loudspeaker normally is interval in printed circuit board (PCB) with a slight distance, so audio amplifier scope between loudspeaker and the printed circuit board (PCB) or air elasticity can become very little.Therefore, when loudspeaker operate, diaphragm in the loudspeaker can difficultly because of the audio amplifier scope of above-mentioned deficiency or air elasticity produce vibrations, that is the diaphragm in the loudspeaker is difficult for and air produces resonance effect, and then makes volume and sound quality that loudspeaker are exported be affected.
In order to overcome above-mentioned problem to improve the volume of loudspeaker, other has a kind of way is that the pairing part printed circuit board (PCB) in loudspeaker below is removed, thus, the audio amplifier scope or the air elasticity of loudspeaker below can increase, thereby have improved the volume that loudspeaker are exported.
Yet configuration electronic component and this genuss of printed circuit board (PCB) are difficult in the finite space of the main frame of notebook computer, if printed circuit board (PCB) is partly removed, will certainly make that the circuit layout (layout) on the printed circuit board (PCB) is difficult more again.
Summary of the invention
In view of this, but the notebook computer that the objective of the invention is to provide a kind of tool to improve the audio function and the electronic installation of play sound effect, it can be the output volume of raising horn assembly under the minimum prerequisite in the suffered influence of the circuit layout on the printed circuit board (PCB).
The present invention includes a display; One main frame, this main frame are articulated in this display and have a upper shell and a lower house, and wherein, this upper shell is with respect to this lower house; One horn assembly, this horn assembly are arranged on this upper shell and have at least one first airport; And a printed circuit board (PCB), this printed circuit board (PCB) is arranged between this upper shell and this lower house and has at least one second airport, and wherein, this second airport position of opening is with respect to this first airport.
Simultaneously, have a notebook computer that improves the audio function according to of the present invention, the size that this first airport is projected on this printed circuit board (PCB) is the rough size that is equal to or less than this second airport.
Again in the present invention, to be projected to the shape on this printed circuit board (PCB) be shape similar in appearance to this second airport to this first airport.
Again in the present invention, this horn assembly also has a loudspeaker monomer, and it is towards this printed circuit board (PCB).
Again in the present invention, also comprise an audio amplifier entity, it is arranged between this second airport and this lower house.
For above-mentioned purpose of the present invention, feature and advantage can be become apparent, preferred embodiment cited below particularly and conjunction with figs. are elaborated.
Description of drawings
Fig. 1 shows that tool of the present invention improves the schematic perspective view of the notebook computer of audio function;
Fig. 2 is the A-A part diagrammatic cross-section that shows according to the main frame of Fig. 1;
Fig. 3 looks synoptic diagram in the demonstration end with horn assembly of the notebook computer that improves the audio function of the present invention; And
Fig. 4 looks synoptic diagram in the demonstration end with printed circuit board (PCB) of the notebook computer that improves the audio function of the present invention.
Embodiment
See also Fig. 1 and Fig. 2, improve the notebook computer 100 of audio function but the electronic installation of play sound effect of the present invention can be a tool, it mainly includes a display 110, a main frame 120, two horn assemblies 130 and printed circuit board (PCB)s 140.
As mentioned above, even the lower end of horn assembly 130 (or loudspeaker monomer 131) is to be interval in printed circuit board (PCB) 140 with a slight distance, but the flowability of air can increase because of the existence of second airport 141 on the printed circuit board (PCB) 140, in other words, air elasticity between horn assembly 130 and printed circuit board (PCB) 140 can increase, simultaneously, because the existence of second airport 141 on the printed circuit board (PCB) 140, the audio amplifier scope of horn assembly 130 belows can be extended to lower house 122 places of main frame 120.Therefore, when horn assembly 130 runnings, diaphragm in the loudspeaker monomer 131 promptly can produce vibrations easily because of audio amplifier scope or the air elasticity that increases, that is the diaphragms in the loudspeaker monomer 131 can produce resonance effect with air easily, and then can promote volume and the sound quality that horn assembly 130 is exported.
In addition, it should be noted that, if space permission, between the lower house 122 of second airport 141 of printed circuit board (PCB) 140 and main frame 120, can add an audio amplifier entity 150 again, thus, diaphragm in the loudspeaker monomer 131 also can produce resonance effect with air easily, and the sound quality that horn assembly 130 is exported may be better.
In addition, but the electronic installation of play sound effect of the present invention can also be electronic installations such as the PDA that only has a main frame, MP3 player, and the structure of the main frame 120 of the structure of its main frame and notebook computer 100 is identical, and the repetitive description thereof will be omitted at this.
In sum, the present invention has a greatest feature, that is, can be enhanced under for minimum prerequisite in the suffered influence of the circuit layout on its printed circuit board (PCB) 140 but have volume that the horn assembly 130 of the electronic installation of the notebook computer 100 that improves the audio function or play sound effect exports.
Though the present invention is exposed in preferred embodiment; yet it is not in order to limit the present invention; any person skilled in the art person; without departing from the spirit and scope of the present invention; when the variation that can make all equivalences or replacement, so protection scope of the present invention is when looking accompanying being as the criterion that the application's claim scope defined.
