As shown in Figure 3, the positioning pieces 120a, 120b, 120c, and 120d are arranged in an outward direction from the center of the vibration panel. When the invisible speaker 100 is to be installed in the installation surface, the direction of the positioning piece is parallel to the installation surface. In other words, the positioning piece is parallel to the front surface of the vibration panel 110 . When the flat-panel invisible speaker 100 is to be installed on the installation surface, the front surface of the positioning piece is also substantially flush with the front surface of the vibration panel 110 . In this embodiment, the back sides of the positioning pieces 120a, 120b, 120c, and 120d are in contact with the mounting surface. At this time, the front side of the positioning pieces is flush with the front side of the vibration panel 110. In another embodiment, the back surfaces of the positioning pieces 120a, 120b, 120c, and 120d (ie, the surfaces facing away from the mounting surface) may be flush with the front surface of the vibration panel. In another embodiment, the positioning pieces 120a, 120b, 120c, 120d can be pressed into the mounting surface.

The rear surface is the surface on which the installation surface fits during the installation process of the invisible speaker 100 . The nut of the countersunk head screw can be inserted into the recess so that it is flush with the front of the locating tab. FIG. 4 is only a schematic diagram of the label 120 a and does not show the countersunk feature of the notch 210 .
In one embodiment of the present invention, the positioning piece 120a is made of metal, which may be steel, and is very thin so that the thickness of the required gypsum layer covering the positioning piece 120a is as small as possible. Furthermore, the positioning piece 120a is difficult to observe on the mounting surface. The positioning piece 120a can also be made of other materials, such as carbon fiber. The positioning piece 120a can be made into an integral part formed integrally with the vibration panel or the mounting frame.
