The oval-shaped bobbin 550 may improve the sound of the high-pitched range than the circular-shaped one, and may generate less heat due to vibration, and thus may have excellent heat dissipation characteristics.

The coil 560 according to some embodiments of the present specification may be wound around the outer circumferential surface of the bobbin 550 to receive a current (or voice current) for generating a sound from the outside. For example, the coil 560 may be raised and lowered together with the bobbin 550 . The coil 560 may be expressed as a voice coil or the like. When a current is applied to the coil 560 , the entire bobbin 550 moves up and down according to Fleming's left hand rule based on the applied magnetic field formed around the coil 560 and the external magnetic field formed around the magnet 520 . will do A sound PVS or sound wave is generated by vibration of the display module 100 due to vertical movement (or vibration) of the bobbin 550 .

FIG. 7 is a diagram illustrating an example of the partition shown in FIG. 2 . 8 is a diagram illustrating another example of the partition shown in FIG. 2. Referring to FIGS. 2, 7, and 8, the partition 800 according to some embodiments of the present specification includes first to fourth sub-partitions. (810, 820, 830, 840) may be included, but is not limited thereto. For example, the partition 800 may be disposed between the vibration device 500 and the middle frame 700 . For example, each of the first to fourth sub-partitions 810 , 820 , 830 , and 840 may have a line shape having a predetermined width and length, and may have the same or different widths and lengths.

According to some embodiments of the present specification, based on a plan view of the support member 300 shown in FIG. 7 , the first support member 310 includes a first front edge portion (or left side), a first front edge portion, and A second front edge portion (or right side) parallel to each other, a third front edge portion (or upper side) between one side of each of the first and second front edge portions, and first and second portions parallel to the third front edge portion A fourth front edge portion (or lower side) between the other side of each of the front edge portions may be included.

Each of the first to fourth sub-partitions 810 , 820 , 830 , and 840 may have a structure separated from each corner of the first support member 310 . For example, each of the first to fourth sub-partitions 810 , 820 , 830 , and 840 may have a non-separable rectangular band shape.

A portion of each of the first to fourth sub-partitions 810 , 820 , 830 , and 840 is arranged to be in contact with the adjacent sub-partitions 810 , 820 , 830 , 840 at each corner portion of the first support member 310 , thereby partitioning the partition. It is possible to minimize leakage of sound waves generated in the vibration space defined by 800 to the outside.

At least one of the first to fourth sub-partitions 810 , 820 , 830 , and 840 may include a bent portion facing the vibration device 500 . In the embodiment of the present specification, the vent parts 831 and 841 are configured in one or more of the third and fourth sub-partitions 830 and 840, but are not limited thereto. For example, the vent unit may be equally or similarly applied to the first and second sub-partitions 810 and 820 .

Sound waves generated by vibrating the display module 100 by the vibrating device 500 propagate radially from the center of the vibrating device 500 . This sound wave may be referred to as a progressive wave, and while the traveling wave propagates in a radial direction, it is reflected by the partition 800 to form a reflected wave that travels in the opposite direction to the traveling wave. This reflected wave overlaps and interferes with the traveling wave to form a standing wave that does not propagate the superimposed sound wave and is stagnant at a certain position. The sound pressure may be reduced by the standing wave, and thus the sound output characteristics may be deteriorated. Accordingly, the vents 831 and 841 are configured in the partition 800 to reduce the sound pressure reduction phenomenon due to the standing wave generated by the interference between the reflected wave and the traveling wave. For example, the vent parts 831 and 841 are configured at a point where the magnitudes of the traveling wave and the reflected wave are large among the first to fourth sub-partitions 810 , 820 , 830 , and 840 , or at least one connection part where the strongest sound wave arrives. can be For example, the vent portions 831 and 841 are positioned toward the center of the vibrating device 500, for example, on the extension line EL of the center of the vibrating device 500, thereby reducing the sound pressure caused by the standing wave. can be minimized

The inclination angle θ of the vent portions 831 and 841 according to some embodiments of the present specification may vary depending on the required amount of suppressing the standing wave, for example, may be set to vary from 10° to 30°. For example, when the vibration device 500 outputs low-pitched sound or the output of the vibration device 500 is high, the vents 831 and 841 may have a relatively large inclination angle θ. For example, when the vibration device 500 outputs a high-pitched sound or the output of the vibration device 500 is small, the vents 831 and 841 may have a relatively small inclination angle θ.

Each of the third and fourth sub-partitions 830 and 840 may have a left-right symmetric structure with respect to the vents 831 and 841 . The vent portions 831 and 841 may have a structure that is opened on the extension line EL of the center of the vibration device 500 , but is not limited thereto, and may have a closed structure in the shape of '∨'. When the vents 831 and 841 have a structure in which the vents 831 and 841 are perforated on the extension line EL of the central portion of the vibration device 500 , there is an advantage in that the material cost can be reduced compared to the case in which the vent portions 831 and 841 have a blocked structure. And, according to the acoustic characteristic experiment, when the vent parts 831 and 841 have a structure in which the vents 831 and 841 have a structure that is open on the extension line EL of the center of the vibration device 500 and a structure that is blocked, the difference in acoustic characteristics is insignificant or It was confirmed that no

At least one of the first to fourth sub-partitions 810 , 820 , 830 , and 840 may include at least one or more protrusions 850 and 860 facing the vibration device 500 . For example, as shown in FIG. 7 , at least one or more protrusions 850 and 860 may be configured in each of the first and second sub-partitions 810 and 820 to face the center of the vibration device 500 . . For example, as shown in FIG. 8 , the protrusions 870 and 880 may be equally or similarly applied to the third and fourth sub-partitions 830 and 840 . At least one or more protrusions 850 , 860 , 870 , and 880 may trap the reflected wave of the vibration device 500 , thereby reducing a peak or dip phenomenon caused by a standing wave, thereby minimizing a sound pressure reduction phenomenon.

At least one or more protrusions 850 , 860 , 870 , and 880 are configured as one, but the present invention is not limited thereto. For example, in FIG. 7 , the protrusions 850 , 860 may include two or more. For example, two or more protrusions 850 and 860 may be formed in each of the first and second sub-partitions 810 and 820 . For example, the two or more protrusions 850 and 860 may be configured above and below each of the first and second sub-partitions 810 and 820 with the vibration device 500 interposed therebetween.
