ができる。According to the embedded speaker mounting structure according to the present invention described in detail above, the first aspect of the present invention provides a spring receiving member for hooking a spring member attached to the embedded speaker to the U-shaped support bracket side. Therefore, the spring member can be used in a case where the U-shaped support bracket and the first and second L-shaped fixtures are not securely fastened or when the fastening is loosened due to a temporal change due to vibration of the embedded speaker. The embedded speaker is reliably supported by the U-shaped support bracket through the hole of the fixing member (ceiling plate) by the urging force, and the decorative panel of the embedded speaker does not float from the fixing member, and the embedded speaker is Since it does not drop from the fixing member, it is possible to secure not only safety during work but also safety after mounting. Further, it is possible to mount the built-in speaker with the workability and maintainability, specifically, the speaker mounting assembled and configured on the fixing member. Furthermore, since the L-shaped fixture has a curved surface, when assembling the L-shaped fixture to the U-shaped support bracket, the speaker can be inserted into the hole of the fixing member in a state where the speaker attachment is temporarily assembled. Even after the speaker attachment is inserted into the hole of the fixing member, the fastening operation of the screw fastening member can be performed efficiently.

構造。3. An embedded speaker mounting structure for mounting an embedded speaker in a state of being embedded in a hole of a fixing member such as a ceiling plate or a wall, wherein the first and second ends are bent from one surface to oppose each other. 2
A vertical surface is formed in a substantially U-shape, and one end of each of the first and second vertical surfaces is outwardly bent symmetrically to form first and second flange surfaces. A U-shaped support fitting formed with a through hole at a location and having a screw fastening portion formed on the first and second vertical surfaces; A tension spring member having a portion passing through the two through holes and suspending to the inside of one surface, and having a detachment preventing member attached in the middle of the suspension; and a first vertical surface of the U-shaped support bracket. A vertical surface and a flange surface facing the first flange surface are bent and formed in a substantially L shape, and one end of the vertical surface is bent in a substantially R shape in a direction opposite to the flange surface to form a curved surface. A first L-shaped fixture having slits formed in the vertical and curved surfaces in a vertical direction; A vertical surface and a flange surface facing the second vertical surface and the second flange surface of the cylindrical support are bent and formed substantially in an L-shape, and one end of the vertical surface is formed in a substantially R shape in a direction opposite to the flange surface. A second L-shaped fixture having a curved surface formed by bending into a curved shape, and a slit formed in the vertical and curved surfaces in a longitudinal direction; and a first of the U-shaped support fittings inserted from a hole of the fixing member. , The vertical surfaces of the first and second L-shaped fixtures are aligned with the second vertical surface according to the thickness of the fixing member, and the first and second flange surfaces of the U-shaped support bracket are connected to the first and second L-shaped fixing members. Fastened via the screw fastening portion of the U-shaped support bracket and the slit of the first and second L-shaped fixtures so as to be sandwiched in the hole of the fixing member between the flange surface of the second L-shaped fixture and the flange. Comprising a screw fastening member to be assembled and assembled to the fixing member to the speaker mounting concrete A decorative panel is mounted on the front surface of the speaker body, and an embedded speaker provided with a pair of spring support portions on the speaker body side is inserted into the hole of the fixing member from the speaker body side, and the pair of springs is inserted. An embedded speaker mounting structure, wherein both ends of the tension spring member suspended from the U-shaped support bracket are locked to a support portion.
