When a CD or DVD (not shown) is played on the notebook personal computer configured as described above, sound is played from the speaker unit 44 with the display unit 42 opened.
[0006]
[Problems to be solved by the invention]
In general, an information processing apparatus with a built-in speaker unit is required to reproduce a powerful sound in a low sound range. In reproducing CDs and DVDs, powerful sounds are required, but in recent years information processing devices place importance on portability and often employ small speaker units.
[0007]
In general, the frequency characteristics can be ensured by placing the speaker in a container having a back capacity suitable for the vibration energy. However, the conventional information processing apparatus with a built-in speaker unit has a problem that the volume of the back surface that satisfies the characteristics of the speaker is insufficient, making it difficult to reproduce the low-frequency region, resulting in failure to reproduce powerful sound. Such an information processing device requires a powerful sound at the time of reproduction of a CD, a DVD, etc., so that it has an amplification circuit that increases the sound and a large-diameter speaker unit and has a docking station that secures its rear volume, A speaker unit with a built-in amplification circuit was connected to the outside. However, connecting other devices outside reduces portability.
[0008]
An object of the present invention is to make it possible to reproduce a powerful sound in a low frequency range without impairing portability in an information processing apparatus with a built-in speaker unit.
[0009]
[Means for Solving the Problems]
In order to solve this problem, the present invention is configured such that a speaker unit is arranged on a display unit, and when the display unit is opened, the sound emission direction of the speaker unit is the direction of the installation surface of the information processing apparatus main body. It is.
[0010]
As a result, an information processing apparatus with a built-in speaker unit that enables reproduction of powerful sounds in the low sound range while maintaining portability can be obtained.
[0011]

[0020]
The invention described in claim 3 is the information processing apparatus with built-in speaker unit according to claim 1 ,
In addition to the speaker unit for the bass, and a medium or high tone loudspeaker which is characterized in that the distribution elsewhere in the information processing apparatus, so as to reflect the bass radiation waves equipment installation surface, heavy A powerful sound with a low frequency can be reproduced, and the other mid-high range is covered by another speaker.
[0021]
Hereinafter, embodiments of the present invention will be described with reference to FIGS. 1 to 3.
[0022]
(Embodiment 1)
FIG. 1 is an external perspective view showing a portable notebook personal computer which is an information processing apparatus according to an embodiment of the present invention, and FIG. 2 is a cross-sectional view. In the figure, reference numeral 1 denotes a main body portion of the notebook personal computer, and 2 denotes a display portion that is rotatably attached to the main body portion 1 by a hinge 3. The display unit 2 includes a display panel 2a and a housing 2b that protects the display panel 2a. Reference numeral 4 denotes a low-frequency speaker unit built in the display unit 2, and is attached so that the sound emission direction is directed downward with the display unit 2 opened. 2c is a sound outlet provided in the housing 2b, and 2d is a cavity in the housing 2b. Reference numeral 5 denotes a middle / high tone speaker unit built in the main body 1 and is attached with the sound emission direction facing upward. Reference numeral 6 denotes an installation surface of the notebook computer.
[0023]
When a CD or DVD (not shown) is played back on the notebook computer configured as described above, the display unit 2 is rotated around the hinge 3, and the display unit 2 is moved to the normal use angle (about 120) as shown in the figure. Sound is output from the speakers 4 and 5 in a state where the speaker 4 and 5 are open. When the sound comes out of the speaker, a high / mid range is generated by the electric circuit from the speaker unit 5 of the main body 1, and the low-frequency sound is generated by the low-frequency speaker 4 disposed in the housing 2 b on the back of the display unit 2. The low-frequency reflected wave passes through the lower cavity 2d and is emitted from the sound outlet 2c. The bass reflected wave coming out of the sound emission opening 2c hits the installation surface 6 in a state where the display unit 2 is opened at the normal use angle. By colliding with the installation surface 6, the installation surface 6 resonates and a more powerful bass reproduction can be performed.
[0024]
In the present embodiment, the sound emission direction with respect to the installation surface 6 of the speaker unit 4 varies depending on the square angle of the display unit 2, but the effect is greatest at a normal use angle (about 120 degrees). Actually, an angle of 100 to 120 degrees is desirable.
[0025]
In the present embodiment, since the speaker unit is arranged in the housing of the display unit, it is possible to eliminate restrictions on appearance such as design.
[0026]
Further, since the speaker unit is arranged on the back surface of the display unit, the display area can be utilized to the maximum.
[0027]
In this embodiment, the speaker unit is arranged in the housing of the display unit. However, if the speaker unit is detachably attached to the outside of the display unit housing, bass reproduction can be effectively performed only when necessary. Can do.
[0028]
(Embodiment 2)
FIG. 3 is a sectional view showing a portable notebook personal computer that is an information processing apparatus according to the second embodiment of the present invention. In the figure, reference numeral 11 denotes a main body of a notebook personal computer, and reference numeral 12 denotes a display unit rotatably attached to the main body 11 by a hinge 13. The display unit 12 includes a display panel 12a and a casing 12b that protects the display panel 12a. Reference numeral 14 denotes a low-frequency speaker unit built in the main body 11 and is attached so as to emit sound from the bottom surface of the main body 11. Reference numeral 15 denotes a middle / high tone speaker unit built in the main body 1, which is attached with the sound emission direction facing upward. Reference numeral 16 denotes an installation surface of the notebook computer.
[0029]
When playing a CD or DVD (not shown) in the notebook computer configured as described above, when outputting sound from a speaker, the high / midrange sound region is higher than the speaker unit 15 of the main body 11 by an electric circuit. The sound of the bass component is generated downward from the bass speaker unit 14 arranged in the main body 11. The low-frequency sound reflected from the low-frequency speaker unit 14 hits the installation surface 16. By colliding with the installation surface 16, the installation surface 16 resonates, and more powerful bass reproduction can be performed.
[0030]
In the above description of the embodiment, the example in which the low-frequency speaker is arranged on the back surface of the display unit and the example in which the low-frequency speaker is arranged on the bottom surface of the main body unit has been described. Any place can be used, and for example, if low-frequency speaker units are arranged on the left and right side surfaces of the display unit, it is not necessary to increase the size in the thickness direction, and the information processing apparatus can be made thin.
[0031]
【The invention's effect】
As described above, according to the present invention, in the information processing apparatus with a built-in speaker unit, the low-frequency speaker unit is arranged on the back surface of the display unit or the bottom surface of the main body unit, thereby preventing the portability of the information processing device. An advantageous effect of enabling the reproduction of a powerful sound in a low bass region is obtained.
