And Fig. 4 is a drawing for explaining a first body (101) of a portable electronic device (100) according to one embodiment of the present invention.
[0057] Hereinafter, in describing a portable electronic device (100) according to one embodiment of the present invention, the forward and backward directions will be described based on the x-axis direction, the left and right directions will be described based on the y-axis direction, and the up and down directions will be described based on the z-axis direction.
[0058] A portable electronic device (100) according to one embodiment of the present invention may be composed of a pair of bodies (101, 102). Referring to FIGS. 2 to 4 together, a hinge axis (1011) may be positioned at an end of the first body (101) in a first direction (y-axis direction). In addition, a second body (102) may be rotatably coupled at one side about the hinge axis (1011). That is, the second body (102) may include a fixed cover (1021) that covers the periphery of a display (151) positioned on the first surface and is coupled to the hinge axis (1011).

[0059] Accordingly, a portable electronic device (100) according to one embodiment of the present invention can be switched from a closed state in which a second body (102) is arranged to overlap the upper surface of a first body (101) as shown in FIG. 2 to an open state in which the angle between the first body (101) and the second body (102) widens as shown in FIG. 3.
[0060] Here, the unfolded state is a state in which the portable electronic device (100) of the present invention is used, and the angle of the second body (102) can be fixed to an angle desired by the user so that the first surface where the display (151) of the second body (102) is located is arranged in a direction perpendicular to the user's line of sight.
[0061] The first body (101) is used by placing it on a surface, so the surface where the first body (101) and the second body (102) overlap when closed can be defined as the upper surface, and the surface opposite to that, which is placed on the floor, can be defined as the lower surface. In addition, the second body (102) rotates and the upper and lower positions change, so the surface overlapping the first body (101) can be defined as the first surface, and the surface opposite to that can be defined as the second surface.
[0062] The first body (101) may include a main board and an electronic chip such as a CPU mounted on the main board as a control unit (180), and may include an input device (123) described above through FIG. 1 on the upper surface.

[0064] The second body (102) may include a display (151). The display (151) may be implemented by a liquid crystal display (LCD), a thin film transistor liquid crystal display (TFT LCD), an organic light-emitting diode (OLED), a flexible display, a 3D display, or the like.
[0065] FIG. 5 is a drawing illustrating a first sound output hole (1012) formed in a first side portion (101a) of a portable electronic device (100) according to one embodiment of the present invention. FIG. 6 is a cross-sectional view taken along line AA of FIG. 3. FIG. 7 is a drawing illustrating area B of FIG. 3. And FIG. 8 is a drawing illustrating a second sound output hole (1014a) formed in a keypad cover (1014) of a portable electronic device (100) according to one embodiment of the present invention.
[0066] In a portable electronic device (100) according to one embodiment of the present invention, a first body (101) may include a first side portion (101a). A first sound output hole (1012) may be formed in the first side portion (101a). In addition, a first speaker module (1013) may be positioned inside the first body (101), and the first speaker module (1013) may output sound through the first sound output hole (1012).
[0067] Here, the first speaker module (1013) may include a first speaker (1013a) that outputs sound and a first bracket (1013b) on which the first speaker (1013a) is mounted. In addition, the first speaker module (1013) may include a first sound passage (1013c) that is arranged in a second direction (x-axis direction) perpendicular to the first direction (y-axis direction) and has one end connected to the first bracket (1013b) and the other end connected to the first sound output hole (1012). In particular, the first speaker (1013a) may include a tweeter that generates sound in a high-pitched range.
[0068] In particular, a portable electronic device (100) according to one embodiment of the present invention can cause a sound output through a first sound output hole (1012) to be reflected on one side of the first surface of the second body (102) when the second body (102) is open. This is because the sound in the high-pitched range has strong straightness, so it can be reflected on one side of the first surface of the second body (102) and the fixed cover (1021) of the second body (102), and can be directly transmitted to the user through this.
[0069] Accordingly, the user can feel as if the sound is coming from the screen of the display (151) by being linked to the display (151) located on the first side of the second body (102). This can have the effect of improving the user's immersion.
[0070] In addition, in a portable electronic device (100) according to one embodiment of the present invention, the first body (101) may include a keypad cover (1014) coupled to the upper surface. FIG. 7 is a drawing illustrating area B of FIG. 3, where (a) of FIG. 7 is a drawing illustrating the upper surface of the first body (101) before the keypad cover (1014) is coupled, and (b) of FIG. 7 is a drawing illustrating the upper surface of the first body (101) to which the keypad cover (1014) is coupled.
[0071] Here, in a portable electronic device (100) according to one embodiment of the present invention, the keypad cover (1014) may include a second sound output hole (1014a) formed at a position corresponding to the first speaker (1013a) as illustrated in FIG. 8.
[0072] Accordingly, the sound output through the first speaker (1013a) can be directly transmitted to the user by being reflected on one side of the first surface of the second body (102) through the first sound output hole (1012) as described above, and can additionally be directly transmitted to the user through the second sound output hole (1014a).
[0073] That is, the portable electronic device (100) according to one embodiment of the present invention can improve audio performance by outputting high-pitched sounds that are directly transmitted to the user through the first sound output hole (1012) and the second sound output hole (1014a), thereby allowing the user to hear the sounds more richly.
[0074] Fig. 9 is a cross-sectional view taken along line CC of Fig. 3. And Fig. 10 is a drawing illustrating a palm rest cover (1017) of a portable electronic device (100) according to one embodiment of the present invention.
[0075] Referring to FIGS. 4 to 8 described above, in a portable electronic device (100) according to one embodiment of the present invention, a first body (101) may include a first side portion (101a) and a second side portion (101b) adjacent thereto. In addition, a third sound output hole (1015) may be formed at a lower portion of the second side portion (101b). In addition, the first body (101) may include a second speaker module (1016) positioned therein and outputting sound through the third sound output hole (1015).
[0076] Here, the second speaker module (1016) may include a second speaker (1016a) that outputs sound and a second bracket (1016b) on which the second speaker (1016a) is mounted. In particular, the second speaker (1016a) may include a woofer that generates sound in the low-pitched range.
[0077] Referring to FIG. 3 and FIG. 9 together, the third sound output hole (1015) formed at the lower portion of the second side portion (101b) may include a slit shape formed in the x-axis direction. In addition, through this slit-shaped third sound output hole (1015), the sound of the low-pitched range generated from the second speaker (1016a) can be output in both directions in the y-axis direction.
[0078] In addition, in a portable electronic device (100) according to one embodiment of the present invention, the second speaker module (1016) may include a passive radiator (1016c) coupled to the upper portion of the second bracket (1016b). The passive radiator (1016c) may transmit vibrations toward the upper surface of the first body (101) in conjunction with the second speaker (1016a). In addition, the first body (101) may include a palm rest cover (1017) coupled to the upper surface and spaced apart from the passive radiator (1016c).
[0079] The palm rest cover (1017) can be positioned so that the user's wrist area is positioned when the first body (101) and the second body (102) are open, as illustrated in FIG. 3. That is, the portable electronic device (100) according to one embodiment of the present invention transmits the vibration of the passive radiator (1016c) to the user's wrist area positioned on the palm rest cover (1017), thereby allowing the user to feel that the low-pitched sound has increased.
[0080] Accordingly, a portable electronic device (100) according to one embodiment of the present invention can output low-frequency sounds through a third sound output hole (1015) formed in a second side portion (101b) of a first body (101), and additionally transmit vibrations to a user through a passive radiator (1016c), thereby improving audio performance.
[0081] In particular, a portable electronic device (100) according to one embodiment of the present invention may include an adhesive member (1018) applied in a rim shape along the lower periphery of a palm rest cover (1017) to form a sealed space for enhancing the vibration transmission effect of a passive radiator (1016c). Accordingly, the passive radiator (1016c) and the palm rest cover (1017) are bonded through the adhesive member (1018), and the internal space is sealed, thereby effectively transmitting the vibration of the passive radiator (1016c) to the palm rest cover (1017).
[0082] In summary, the portable electronic device according to the present invention can directly transmit sound output through the first side of the first body to the user by reflecting it on the front of the second body. Furthermore, the device can output sound through the second side of the first body and transmit vibrations toward the upper surface of the first body through a passive radiator.
