In one embodiment, the buffer structure 153 is disposed in the fixing hole 149 to wrap around the screw 152 so as to absorb the vibration of the first housing component 142 or the second housing component 143.

請參照第4圖，導音通道146設置於第一殼體組件142下方，與朝第一方向A設置的喇叭單體144的出音面145相連(彼此相鄰)，導音通道146例如與第一殼體組件142一體成形，或是導音通道146以黏膠或螺絲151固定於第一殼體組件142上，本發明對此不加以限制。也就是說，喇叭單體144可發出一聲音沿第一方向A傳播。此外，導音通道146例如具有一導音斜面148，此導音斜面148相對於出音面145傾斜，導音斜面148例如為平斜面、圓弧形斜面或S形彎曲面等，且導音斜面148的水平傾斜角可為5至85度，較佳為30至60度。也就是說，喇叭單體144可發出一聲音沿第一方向A傳播而經由導音斜面148反射轉為沿第二方向B傳播，第一方向A與第二方向B之間角度例如為正交的直角、小於90度或大於90度，本發明對此不加以限制。 Please refer to Fig. 4, the sound guide channel 146 is disposed under the first housing assembly 142, and is connected to the sound emitting surface 145 of the speaker unit 144 arranged in the first direction A (adjacent to each other). The sound guide channel 146 is connected to, for example, The first housing component 142 is integrally formed, or the sound guide channel 146 is fixed on the first housing component 142 with glue or screws 151, which is not limited by the present invention. In other words, the speaker unit 144 can emit a sound to travel along the first direction A. In addition, the sound guiding channel 146 has, for example, a sound guiding inclined surface 148 which is inclined with respect to the sound emitting surface 145. The sound guiding inclined surface 148 is, for example, a flat inclined surface, a circular arc inclined surface, or an S-shaped curved surface, and the sound guiding inclined surface 148 The horizontal inclination angle of the inclined surface 148 may be 5 to 85 degrees, preferably 30 to 60 degrees. In other words, the speaker unit 144 can emit a sound that travels along the first direction A and is reflected by the sound guide slope 148 to travel along the second direction B. The angle between the first direction A and the second direction B is, for example, orthogonal. The right angle is less than 90 degrees or greater than 90 degrees, which is not limited by the present invention.

另外，喇叭單體144的出音面145除了朝下設置之外，亦可傾斜設置，只要能減少喇叭單體144的縱向截面積即可。由於喇叭單體144的出音面145朝下設置，喇叭單體144的縱向截面積為最小，因此可減少縱向空間需求。相對於喇叭單體144的出音面145朝前或朝後設置的方式，喇叭單體144的縱向截面積為最大，因而無法減少縱向空間需求。 In addition, the sound emitting surface 145 of the horn unit 144 can be arranged in an inclined manner, as long as the longitudinal cross-sectional area of the horn unit 144 can be reduced. Since the sound emitting surface 145 of the horn unit 144 is arranged downward, the longitudinal cross-sectional area of the horn unit 144 is the smallest, so that the longitudinal space requirement can be reduced. Compared with the manner in which the sound emitting surface 145 of the horn unit 144 is arranged forward or backward, the longitudinal cross-sectional area of the horn unit 144 is the largest, and thus the longitudinal space requirement cannot be reduced.

請參照第4圖，第一殼體組件142與第二殼體組件143之間的間隙形成導音通道146的出音口147，出音口147具有一縱向寬度尺寸C1以及一縱向長度尺寸，也就是說，出音口147的面積為縱向寬 度尺寸C1與縱向長度尺寸的乘積。此外，喇叭單體144的出音面145具有一橫向寬度尺寸C2以及一橫向長度尺寸，也就是說，出音面145的面積為橫向寬度尺寸C2與橫向長度尺寸的乘積。在本實施例中，在縱向/橫向長度尺寸不變或相同的情況下，出音口147的縱向面積可小於出音面145的橫向面積，或是出音口147的縱向寬度尺寸C1可小於出音面145的橫向寬度尺寸C2，以縮小出音裝置140a的縱向空間需求。 Referring to Fig. 4, the gap between the first housing component 142 and the second housing component 143 forms the sound outlet 147 of the sound guide channel 146. The sound outlet 147 has a longitudinal width dimension C1 and a longitudinal length dimension. In other words, the area of the sound outlet 147 is longitudinally wide The product of the degree dimension C1 and the longitudinal length dimension. In addition, the sound output surface 145 of the speaker unit 144 has a lateral width dimension C2 and a lateral length dimension, that is, the area of the sound output surface 145 is the product of the lateral width dimension C2 and the lateral length dimension. In this embodiment, the longitudinal area of the sound outlet 147 may be smaller than the lateral area of the sound outlet surface 145, or the longitudinal width dimension C1 of the sound outlet 147 may be smaller than The horizontal width dimension C2 of the sound output surface 145 is to reduce the longitudinal space requirement of the sound output device 140a.

在另一實施例中，可藉由加大出音口147的縱向長度尺寸，使其大於出音面145的橫向長度尺寸，以使出音口147的面積加大。本發明對此不加以限制。因此，本實施例的出音裝置140a可在出音口147面積不變的情況下，適時縮小喇叭單體144的縱向面積。故，本實施例的顯示器100可在不需額外加大飾板112的尺寸或加大出音口147的面積的情況下，安裝好出音裝置140a，以符合顯示器100的外型設計。 In another embodiment, the longitudinal length of the sound outlet 147 can be enlarged to be greater than the transverse length of the sound outlet surface 145, so that the area of the sound outlet 147 can be enlarged. The present invention does not impose restrictions on this. Therefore, the sound output device 140a of this embodiment can reduce the longitudinal area of the speaker unit 144 in a timely manner under the condition that the area of the sound outlet 147 remains unchanged. Therefore, in the display 100 of this embodiment, the sound output device 140a can be installed without increasing the size of the decorative plate 112 or the area of the sound outlet 147 to conform to the appearance design of the display 100.
