Description

[Detailed Description of the Invention] The present invention relates to a speaker in which a cone paper and an edge are separately formed and bonded together.

Generally, in order to flatten the frequency characteristics of a speaker, a damping agent is applied to the diaphragm as a control member, or a solid material such as rubber is attached to the diaphragm. Either form the parting line corrugate integrally with the cone paper to prevent it from being applied to unnecessary areas, or
A jig that indicates the position of the parting line is used to apply the coating from the top edge of the cone paper to this parting line, but when forming this parting line with the cone paper, depending on the forming conditions of the cone paper, the parting line may be The cone paper has the disadvantage that it protrudes on the opposite side of the required surface, resulting in an unsightly appearance, and that depending on the direction in which the cone paper is made, it is difficult to form a parting line.

Furthermore, when pasting a solid braking member, a molded positioning jig is required that is separate from the jig for applying the damping agent, and the application or pasting work is also complicated. there were.

The present invention was developed in view of the above-mentioned shortcomings. It forms a display part on the edge corresponding to the mounting position of the braking member attached to the diaphragm, eliminates the need to form a parting line on the cone paper, To provide a speaker in which a braking member can be easily attached to a correct position without requiring a brake member.

Next, an embodiment of the present invention will be described with reference to FIGS. 1 and 2.

1 is a cone paper and is formed into a truncated cone shape.

2 is an edge, which includes a flat outer peripheral edge 3 and this outer peripheral edge 3;
It is formed into an annular shape by a groove portion 4 having a semicircular cross section formed continuously on the inner edge of the groove portion 4, and an inclined inner peripheral edge portion 5 continuously formed on the inner edge of the groove portion 4.

Note that four circular holes 6 serving as display portions are opened at equal intervals in the inner peripheral edge portion 5.

This edge 2 is fitted into the cone paper 1, and the cone paper 1
An inner circumferential edge 5 is adhered to the outer surface of the lower edge of the diaphragm 7, and the edge 2 and the cone paper 1 form a diaphragm 7.

A damping agent is applied to the diaphragm 7 from the upper end of the paper cone 1 to the circular hole 6 of the edge 2.

Further, a V-shaped braking member 8 made of rubber or the like is attached to the cone paper 1 in correspondence with each circular hole 6 of the edge 2 above each circular hole 6.

Next, the operation of this embodiment will be explained.

First, adhesive is applied to the inner surface of the inner peripheral edge 5 of the edge 2,
This edge 2 is fitted into the cone paper 1 and pressed against the outer surface of the lower edge of the cone paper 1 to be adhered.

Next, a damping agent (not shown) is applied from the upper end of the paper cone 1 to the circular hole 6 of the edge 2.

At this time, since the circular hole 6 serves as an escape area for the damping agent, the damping agent does not protrude below the circular hole 6.

Next, the braking member 8 is attached to the paper cone 1 at a position corresponding to the upper part of the circular hole 6.

In the above embodiment, a circular hole 6 is provided in the edge 2 as a display section.
However, as shown in FIG. 3, a rectangular hole 11 may be formed.

In addition, when only a solid material such as rubber is used as the braking member 8, as shown in FIG. 4 or FIG. may be formed at equal intervals.

Furthermore, the number of display sections can be formed in accordance with the number of required braking members.

According to the present invention, since the display part is formed on the edge corresponding to the attachment position of the braking member attached to the diaphragm, there is no need to integrally form a parting line etc. on the cone paper as a target for attaching the braking member. The speaker has a good appearance, and the braking member can be easily installed in the correct position without the need for a jig.Therefore, the speaker is complete and can be easily installed even when a jig cannot be used.
