BACKGROUND OF THE INVENTION

1. Field of the Invention

The invention relates to a notebook computer and, more particularly, to a notebook computer capable of improving vibration of a speaker and increasing internal space of the speaker.

2. Description of the Prior Art

In general, a base of a notebook computer consists of a keyboard frame and a bottom cover. At present, a speaker of the notebook computer is assembled into a casing first and then fastened or engaged with the keyboard frame. The thickness of the casing will occupy internal space of the speaker, such that the internal space of the speaker is reduced. Therefore, the speaker will be limited in the performance of the bass, thereby making the bass not deep enough. Furthermore, the casing of the speaker is usually covered with a rubber ring and directly placed on the keyboard frame. Accordingly, when the speaker emits sound, it is easy to cause the system to vibrate and generate abnormal sound.

SUMMARY OF THE INVENTION

The invention provides a notebook computer capable of improving vibration of a speaker and increasing internal space of the speaker, so as to solve the aforesaid problems.

According to an embodiment of the invention, a notebook computer comprises a base, a speaker module and a top cover. The base comprises a keyboard frame and a bottom cover. The keyboard frame is disposed on the bottom cover. The speaker module comprises a speaker cover and a speaker main body. The speaker cover is disposed on the bottom cover to form a resonance chamber between the speaker cover and the bottom cover. The speaker main body is disposed on the speaker cover and located in the resonance chamber. The top cover is pivotally connected to the base.

In another embodiment, the speaker module further comprises a vibration absorbing structure disposed between the speaker cover and the bottom cover.

As mentioned in the above, the invention directly disposes the speaker cover on the bottom cover to form the resonance chamber between the speaker cover and the bottom cover. In other words, an opening of the speaker cover is blocked by the bottom cover, such that there is no need to add additional cover plate. The internal space of the speaker can be effectively increased (i.e. the resonance chamber can be enlarged) without the thickness of the cover plate. Accordingly, the bass of the speaker can have better response. Furthermore, since the speaker cover is disposed on the bottom cover instead of being disposed on the keyboard frame, the vibration generated when the speaker emits sound is not directly transmitted to the keyboard frame, such that the keyboard frame is affected by less vibration and is not easy to generate abnormal sound. Moreover, the invention may dispose the vibration absorbing structure between the speaker cover and the bottom cover, so as to utilize the vibration absorbing structure to absorb the vibration generated when the speaker emits sound, thereby further reducing the abnormal sound generated by the notebook computer due to the vibration of the speaker.

DETAILED DESCRIPTION

Referring toFIGS. 1 and 2,FIG. 1is a schematic view illustrating a notebook computer1according to an embodiment of the invention andFIG. 2is a schematic view illustrating a cross-section of a base10shown inFIG. 1.

As shown inFIGS. 1 and 2, a notebook computer1comprises a base10, a speaker module12and a top cover14. In general, the notebook computer1may be further equipped with some necessary hardware or software components for specific purposes, such as processor, display, circuit board, memory, power supply, applications, communication module, etc., and it depends on practical applications. The base10comprises a keyboard frame100and a bottom cover102. The keyboard frame100is disposed on the bottom cover102to form the base10. In practical applications, the keyboard frame100is used to install a keyboard. A user may lean his/her wrist on a hand rest area of the keyboard frame100to operate the keyboard. The top cover14is pivotally connected to the base10. In general, the top cover14may be pivotally connected to the base10by a hinge or other rotating shafts, such that the top cover14may be closed or opened with respect to the base10.

The speaker module12comprises a speaker cover120and a speaker main body122. The speaker cover120is disposed on the bottom cover102of the base10to form a resonance chamber124between the speaker cover120and the bottom cover102. In this embodiment, the speaker cover120may be adhered to the bottom cover102of the base10to seal a gap between the speaker cover120and the bottom cover102to avoid air leakage. Needless to say, the speaker cover120may also be fastened to the bottom cover102of the base10by screws or engaging structures. The speaker main body122is disposed on the speaker cover120and located in the resonance chamber124. The speaker main body122is used to emit sound.

As shown inFIG. 2, an opening of the speaker cover120is blocked by the bottom cover102of the base10, such that there is no need to add additional cover plate. The internal space of the speaker can be effectively increased (i.e. the resonance chamber124can be enlarged) without the thickness of the cover plate. Accordingly, the bass of the speaker can have better response. Furthermore, since the speaker cover120is disposed on the bottom cover102of the base10instead of being disposed on the keyboard frame100, the vibration generated when the speaker emits sound is not directly transmitted to the keyboard frame100, such that the keyboard frame100is affected by less vibration and is not easy to generate abnormal sound.

Referring toFIG. 3,FIG. 3is a schematic view illustrating a cross-section of a base10according to another embodiment of the invention. As shown inFIG. 3, the speaker module12may further comprise a vibration absorbing structure126. The vibration absorbing structure126is disposed between the speaker cover120and the bottom cover102of the base10. The vibration absorbing structure126is ring-shaped and a shape of the vibration absorbing structure126is identical to a shape of the opening of the speaker cover120. In this embodiment, the speaker cover120may be adhered to the vibration absorbing structure126and the vibration absorbing structure126may be adhered to the bottom cover102, such that the speaker cover120is disposed on the bottom cover102of the base10to form the resonance chamber124between the speaker cover120and the bottom cover102.

In this embodiment, the vibration absorbing structure126may comprise a flange1260and a side wall1262, wherein the flange1260extends outward from a bottom of the side wall1262. When the speaker cover120is adhered to the vibrating absorbing structure126, a lower edge of the speaker cover120abuts against the flange1260and an inner wall of the speaker cover120abuts against the side wall1262. Then, when the vibrating absorbing structure126is adhered to the bottom cover102of the base10, the vibration absorbing structure126seals a gap between the speaker cover120and the bottom cover102to avoid air leakage. In this embodiment, the vibration absorbing structure126may be a sponge or other vibration absorbing materials according to practical applications. The vibration absorbing structure126can absorb the vibration generated when the speaker emits sound, thereby further reducing the abnormal sound generated by the notebook computer due to the vibration of the speaker.

Referring toFIG. 4,FIG. 4is a schematic view illustrating a cross-section of a base10according to another embodiment of the invention. As shown inFIG. 4, the vibration absorbing structure126comprises a flange1260and a side wall1262. Compared to the embodiment shown inFIG. 3, the difference is that the flange1260of the vibration absorbing structure126extends inward from a bottom of the side wall1262. Therefore, when the speaker cover120is adhered to the vibrating absorbing structure126, a lower edge of the speaker cover120abuts against the flange1260and an outer wall of the speaker cover120abuts against the side wall1262. It should be noted that the principle of the vibrating absorbing structure126has been mentioned in the above, so the repeated explanation will not be depicted herein again.

Referring toFIG. 5,FIG. 5is a schematic view illustrating a cross-section of a base10according to another embodiment of the invention. As shown inFIG. 5, the vibration absorbing structure126comprises a U-shaped recess1264, wherein the U-shaped recess1264surrounds the vibration absorbing structure126. Thus, in this embodiment, a lower edge of the speaker cover120may be inserted into the U-shaped recess1264to fasten the speaker cover120on the vibration absorbing structure126. It should be noted that the principle of the vibrating absorbing structure126has been mentioned in the above, so the repeated explanation will not be depicted herein again.

As mentioned in the above, the invention directly disposes the speaker cover on the bottom cover to form the resonance chamber between the speaker cover and the bottom cover. In other words, an opening of the speaker cover is blocked by the bottom cover, such that there is no need to add additional cover plate. The internal space of the speaker can be effectively increased (i.e. the resonance chamber can be enlarged) without the thickness of the cover plate. Accordingly, the bass of the speaker can have better response. Furthermore, since the speaker cover is disposed on the bottom cover instead of being disposed on the keyboard frame, the vibration generated when the speaker emits sound is not directly transmitted to the keyboard frame, such that the keyboard frame is affected by less vibration and is not easy to generate abnormal sound. Moreover, the invention may dispose the vibration absorbing structure between the speaker cover and the bottom cover, so as to utilize the vibration absorbing structure to absorb the vibration generated when the speaker emits sound, thereby further reducing the abnormal sound generated by the notebook computer due to the vibration of the speaker.
