Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a package holder for a speaker having a flat diaphragm.

Conventional Structure and Problems Conventionally, when packaging a speaker having a flat diaphragm, a holder 2 made of plastic was attached to the front of the speaker 1, as shown in FIGS. 1 and 2. ing. That is, the peripheral part 2a of the holder 2 is press-fitted into the peripheral edge of the frame 5 of the speaker 1,
By locking the protrusion 2b at the lower end to the back side of the frame 5, the protrusion 2c near the center of the holder 2 protects the vibrating parts of the speaker 1, such as the flat diaphragm 3 and the edge 4. This is what I did. Note that 6 and 7 are plates, 8 is a magnet, 9 is a bobbin, and 10 is a voice coil.

However, this holder 2 is only used when packaging the finished speaker 1, and during the manufacturing process, another packaging material is used to protect the flat diaphragm 3, which is easily damaged. Another disadvantage is that another packaging and storage material must be used to protect the semi-finished product in which the flat diaphragm 3 and the edge 4 are bonded together.

Purpose of the invention This invention solves these conventional drawbacks by creating a speaker packaging holder that can be used to protect only a flat diaphragm, a flat diaphragm and an edge bonded together, or a finished product. This is what we provide.

Structure of the invention The invention consists of a recess in which a flat diaphragm can be stored, a flat part provided around the recess in a direction parallel to the bottom of the recess, and a flat part perpendicular to the outermost periphery of the frame. The peripheral part provided in the direction is integrally formed with plastic, and the recessed part can protect only the plane diaphragm, and the recessed part and the flat part can be used to protect the flat diaphragm. The product can be protected, and by press-fitting the peripheral portion into the periphery of the frame, the entire vibrating portion of the completed speaker can be protected by the recessed portion and flat portion.

DESCRIPTION OF EMBODIMENTS FIGS. 3 to 6 show a package holder 11 in an embodiment of the present invention, which has a recess in the center with a size and depth that allows only the flat diaphragm 3 to be accommodated with almost no gaps. A flat part 11b is formed around the flat part 11b, which is large enough to comfortably accommodate the outer periphery of the edge 4, and a mountain part 11 is formed around the flat part 11b.
c, troughs 11d and peaks 11e are sequentially formed, a peripheral part 11f in a direction orthogonal to the flat part 11b is formed on the outermost periphery, and convex parts 11g are formed at several locations at the lower end of the peripheral part 11f, Further, four reinforcing ribs 11h are formed in the radial direction between the peaks 11c and 11e. All of these are made of plastic. Furthermore, Tanibe 11
The bottom surface 11d' of d is set to be lower than the bottom surface of the concave portion 11a and higher than the convex portion 11g, and the distance between the bottom surface 11d' and the bottom surface of the concave portion 11a is equal to that of the frame 5 of the finished speaker. The distance is set larger than the distance between the upper surface and the upper surface of the flat diaphragm 3.

In this way, as shown in FIG.
By housing the flat diaphragm 3 in 1a, it is possible to protect the flat diaphragm 3 from being scratched during the manufacturing process.

In addition, as shown in FIG.
By placing it on b, the flat diaphragm 3 and the edge 4
It can protect the bonded anti-fabric product from being damaged during the manufacturing process.

Then, the peripheral portion 11f is press-fitted into the peripheral edge of the frame 5 of the finished speaker 1 as shown in FIG.
When the convex portion 11g is locked to the back side of the frame 5, the bottom surface of the trough portion 11d comes into contact with the top surface of the frame 5, and as a result, the bottom surface of the concave portion 11a and the flat portion 11b is attached to the finished speaker 1. It comes to be located slightly above plate 3 and edge 4. Therefore, if it is packaged in this state, it can be protected from damage during packaging.

Effects of the invention According to the invention, a single packaging holder can protect a flat diaphragm and a semi-finished product made by bonding it to an edge during the manufacturing process, and can also protect finished products when packaging them. Effects can be obtained.
