FR2722023A3 - Trumpet for producing constant noise volume - Google Patents

Abstract

The trumpet consists of front (11) and middle (12) sections with a rear cover (17), and a membrane (15) held between the middle section and the rear cover. The front section forms a cylinder with its forward end turned outwards in semi-annular shape (11b), and the middle section is made from outer (12a) and inner (12b) concentric cylinders with a gap of varying width between them. The membrane fits over the rear end of the middle section and is held in place by the cover, which is cylindrical in shape and perforated. The trumpet is sounded by blowing into a side hole (16) to vibrate the membrane, and the sound is amplified by the front section.

Description

DESCRIPTION

  The present invention relates to an improved trumpet having new manufacturing characteristics. of form and configuration whose objective is

  safety and maximum efficiency.

  It exists on the market and, because of this. this can be considered as part of the state of the art. a set of elements intended to produce noise such as trumpets and the like. whose external configuration and the impulse and air channeling system are completely distinct and whose purpose is the emission of constant sounds or variable sounds whose combination can form

  determined melodies and music.

  The trumpet according to the invention is a constant noise generating element of large volume and which can be used as an animation element during sporting events, replacing other impelling elements such as the electric horns which, due to their characteristics. are prohibited in sports arenas because they represent a danger in case they are thrown on the field of

  game, due to their considerable weight.

  The trumpet according to the invention. besides generating a constant sound of great intensity, weighs less than 60 g and. therefore, enters the specific standards for this type of object intended for use on playgrounds, which can be easily transported by means of traditional elements such as ropes, cords or the like, which allow the user to wear it around the neck or by hand, thanks to its light weight and small dimensions compared to its large

  sound capacity to generate noise.

  j The trumpet of the invention is formed by a front part, which channels and amplifies the sound emitted, by a part of medium where the sound is really generated thanks to the impulse of the air by the user himself. same and a rear part in which is supported a vibrating membrane of cellophane paper or similar material, rear part in the form of a cover engaging on the middle part of

the trumpet.

  Other details and features of the present invention will become apparent

  more clearly in the following description, in which reference is made

  to the accompanying drawings and in which the preferred details are represented in a somewhat schematic manner. These details are given by way of example, with reference to a possible example of practical implementation but not limited to the details set out here; of this

  fact, this description should be considered from an illustrative point of view and without limitations

of any kind.

  Figure 1 is a side view of the trumpet (10) of the invention, on which we can see the combination of an anterior part (11). a middle part (12) and a rear cover (17): FIG. 2 is an end view of the trumpet (10) on which we can see the perforations (18) of the cover (17) as well as the ring in which the cord is fixed (19); Figure 3 is an exploded longitudinal sectional view of the trumpet (10) on which we can see the separate elements that compose it; Figure 4 is a partial longitudinal sectional view of the various elements which

  make up the trumpet (10) in the assembled state.

  We will now list the different numbered elements: trumpet (10). front part (11), cylindrical part (1 la). semiannular part (1 lb), middle part (12), external cylindrical part (12a). internal cylindrical part (12b), annular part (12c). posterior cylindrical part (12d). curved generator (13), groove (14). paper or cellophane membrane (15) orifice (16). lid

  posterior (17), perforations (18). cord (19). ring (20).

  According to one of the preferred embodiments of what is the subject of the present invention, as can be seen in Figures 3 and 4. the trumpet (10) is formed of a front part (11) which is formed by a cylindrical part (1 la) which

  extends outward in a circumferential semi-annular part (1 lb).

  The front part (11) is pressurized and is joined to the middle part (12) by the projection or internal groove (14). Said middle part (12) is formed by an external cylindrical part (12a). an inner cylindrical part (12b) of smaller diameter, an annular part (12c) which protrudes from the cylindrical part (12a) and which is formed by a curved generator surface (13) and finally a posterior cylindrical part (12d) of diameter higher than the external cylindrical part (12a). To the annular part (12c) is fixed the ring (20) which serves as an element

of attachment to the cord (19).

  The rear part of the trumpet (10) is formed by a rear cover (17) which is essentially cylindrical. as can be seen in Figures 2 and 3, not having a lower face and whose planar upper face is crossed and formed by a set of perforations (18). Said rear cover (17) fits with the rear cylindrical part (12d). the paper or cellophane membrane

(15) being disposed between them.

  Operation of the trumpet (10) requires the impulse of pressurized air from the user through the orifice (16). which produces the vibration of the

  membrane (15) retained between the parts (12d) and (17).

  The sound emitted is channeled outwards through the front part (11) which displaces and amplifies it, producing a constant noise of great intensity by

  compared to the small size of the trumpet.

  It should be noted that one can add to the object which constitutes the present invention all variations and modifications of details which might prove necessary, as long as these variations and modifications introduced do not alter or

  not modify the essence of what has just been described.
