BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is an overall perspective view of a protective
cover, FIG. 2 is a cross-sectional view showing an example applied to a dome-shaped speaker,
and FIG. 3 is an equalizer. Fig. 4 is a sectional view showing an example used as a ribbon type
speaker. 10 иииииии Protective cover, 11 иииииииииииииииииииииииииииииииииииииииииииииииииииииииииииииииииииииииииииииииииииииииииииииии Magnetic

DETAILED DESCRIPTION OF THE INVENTION This invention relates to a speaker storage cover,
and more particularly, to a speaker storage cover for protecting a speaker unit. Loudspeaker unit
t-IL, its assembly process, itjorc to prevent the diaphragm from being broken during
transportation. A strain-force bar can be put on at least the beak. This lint-cover is generally
clipped to the speaker unit with a plastic surface and placed in the speaker unit and the layered
cage. However, there are many cases where this eyelid cover takes a bath from the speaker unit
during fI feeding during the process, and it is impossible to completely achieve the purpose of
desired -1- / 2 ? knee ?The In order to prevent the protective cover and the speaker unit from
being separated unnecessarily at 70, it is necessary to make the fitting state of the protective
cover over the outer diameter of the speaker unit high, and the various shapes are different. A
dedicated stock cover must be created temporarily for each speaker unit. Therefore, this device is
designed so that the protective cover for protecting the [II & of the speaker unit can be cut into a
soft block and can be joined without being softly attached. It is characterized in that the unit or
the magnet is provided (in view of this, the protective cover is magnetically attached to the
speaker unit by utilizing the leakage magnetic flux. Hereinafter, an embodiment of the present
invention will be described along one direction attached. Fig. 1 shows the entire cover, Fig. 2 is a
cross-sectional view of the dome-shaped speaker unit with a protective cover, and a magnet core
is arranged around the 7 / ter pole I, and the yoke 3 and the plate The voice coil 6 is positioned
in the magnetic gap S, and the dome-shaped diaphragm 7 is moved. The periphery of the
diaphragm 7 is supported by a suspension 9 on a frame 9 superimposed on the plate gauze. And

the protective cover IO which covers the diaphragm 7 with this frame is prepared. The stock
capture cover IO is composed of a stock capture cover 1/1 and a magnetic body 2 represented
by an iron piece fixed to the protective cover 1/1. Protective hippocampus integrated l'Hablastic,
etc., is formed by t'L'f 7c, and it is a puzzle r (become diaphragm (? Is it a diaphragm? The
portion that covers the top of the cover has a shape that is elevated so as to cover an appropriate
distance, and a magnetic body 2 such as an iron piece is attached to the central portion of the
protective cover integral io.
In addition, the dome-shaped speaker shown in the 31st is a mesh-shaped storage / cover
integral //, in other words, it has a large number of through holes, and has a constant magnetic
injection pole at the center S. If the protective cover 10 is used, it can be used as a protective
cover 10Fi equalizer. 3- Further, FIG. 4 shows an example of a ribbon type speaker and & @ cover
/ C is covered so that the ribbon type diaphragm 7m can be sealed. The speaker stock farming
cover lo according to the present invention has the above-described configuration. Therefore,
when the speaker farming unit lo is mounted on a speaker unit, a part of the leakage flux of the
magnet forms a loop passing through the magnetic body. By suctioning, the entire cover 10 can
be attracted to the speaker unit. As is apparent from the above description, since the magnetic
tape is provided integrally with the protective cover for the speaker according to the present
invention and the protective cover integrally formed of the nonmagnetic material, the speaker
cover and the speaker unit Even in the non-animal-wearing condition, the magnetism can
securely hold the bonding state, and the functional accuracy of the protective cover is not
required.
