Abstract

PURPOSE: To easily attain adjustment by horizontally moving a ribbon by displacing each crossing support element for supporting the ribbon to a direction at right angles to the longitudinal axis of the ribbon. CONSTITUTION: The end parts of a crossing support element 12 are supported by supporting poles 14a and 14b positioned each at each side edge of a ribbon foil piece 10, and the crossing support element 12 is arranged at right angles to the longitudinal axis of the foil piece 10. At the time of usage, the crossing support element 12 is displayed by rotating the supporting poles 14a and 14b until the ribbon foil piece 10 can be exactly centered, and the foil piece 10 can be exactly centered through the longitudinal direction. Thus, the ribbon 10 can be centered in a simple method, and the adjustment can be easily attained.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a ribbon transducer,
More particularly, it relates to the mounting of the ribbon itself in ribbon transducers, particularly for use in loudspeakers and microphones.

[Conventional technology]

With respect to ribbon transducers, for satisfactory operation it is necessary that the ribbon itself be centered so that its longitudinal axis is properly positioned in relation to the other components. .

Until now, many methods have been used to center the ribbon.
ering a ribbon).

One method is to use shaped magnets shaped for this purpose.

In another alternative configuration, the ribbon is connected to elongated members on its sides and held taut by a spring mechanism.

Such a configuration is complicated and cannot be easily adjusted.

[Problem to be solved by the invention]

SUMMARY OF THE INVENTION The object of the present invention is to overcome these conventional drawbacks and to provide a means for centering the ribbon of the ribbon transducer in a simple manner and for easily adjusting the center.

[Means to solve the problem]

In order to achieve the above object, the present invention employs the following technical configuration.

That is, according to the present invention, a plurality of cross-support elements are provided in a direction transverse to the longitudinal axis of the ribbon, the cross-support elements support the ribbon, and each of the cross-support elements is arranged in a direction transverse to the longitudinal axis of the ribbon. It is displaceable in a direction perpendicular to the axis, thereby causing a consequent lateral movement of the ribbon.

Preferably, the cross-support element comprises a plurality of strips or strips, eg adhesively bonded to one surface of the ribbon, the ends of which are supported on support means.

The support means is adapted to allow movement of the cross-support element in a direction perpendicular to the longitudinal axis of the ribbon.

The invention will be more fully understood below.

Preferred embodiments of the cross-support mounting elements for mounting ribbons of a ribbon transducer according to the present invention will also be described by way of example with reference to the accompanying drawings.

〔Example〕

Referring to the drawings, FIG. 1 shows a ribbon foil piece 10 that forms part of a ribbon transducer, such as a loudspeaker.

A cross support element 12 is provided on the underside of the ribbon foil piece lO.

the cross-supporting elements have the form of strips or strips;
They are bonded to the underside of the ribbon foil piece IO, for example by means of adhesive.

The ends of the cross-support element 12 are supported on support posts 14a and 14b, one on each side edge of the ribbon foil strip, so that the cross-support element 12 is supported on the edges of the ribbon foil strip. arranged at right angles to the longitudinal axis.

Each of the support posts 14a and 14b is provided with a groove at its end, which allows the support post to be rotated, for example with a screwdriver.

The support columns 14a and 14b have front and rear extrusion plates 16a and 15b (extrusion plates).
, respectively, so that the support column can rotate relative to the projecting plate and maintain its adjusted position.

The front and rear projecting plates 16a and 16b also act as support plates for the magnet 18, which is held in place by the rear plate 20.

In use, in order to center the ribbon foil piece 10,
It is simply necessary to displace the cross-support element 12 by rotating the support column until the ribbon foil piece is accurately centered.

A maximum displacement of 1 mm plus or minus is usually sufficient.

The ribbon foil strip 10 is preferably provided with a plurality of cross-support elements 12 along its length, so that the foil strip is accurately centered throughout its length.

As alternative attachment methods, the cross-support element 12 may be configured within the scope of the present invention.

For example, instead of providing support posts on both sides of the ribbon foil strips as shown in FIG.
It can also be mounted between two edges 22, 23 of a generally U-shaped support member 24 molded from plastic.

Adjustment means may also be provided for moving the cross-support element 12 in relation to the U-shaped support member 24.

Alternatively, the U-shaped support member 24 can also be constructed as a movable body with the cross support elements 12 in order to carry out the required adjustment.

Many other alternative methods of attachment and support will be apparent to those skilled in the art.
