Description

ACOUSTIC DEVICE FOR PASSIVELY AMPLIFYING SOUNDS AND NOISES
Technical Field
This invention relates to an acoustic device for listening to sounds and noises. Background AIIL It is a known fact that the circumstances, both of a working and recreational nature, in which the need is felt to perceive the sounds and noises of the surrounding environment in a clear and clean way, and without the aid of electric and/or electronic instruments, are increasingly more frequent. Such need, for example, is felt to listen to music concerts, both in closed and open locations, to attend opera and theatre performances and/or to take part in congresses, meetings, conferences and lessons in classrooms, auditoriums and rooms set up for the purpose.
In this respect, the fact is underlined that to upgrade the quality of sound transmission, certain environments such as theatres, cinemas, conference halls and auditoriums are originally designed according to pre-established rules and principles.
Notwithstanding this however, the perception of the sound is not always perfect for all the people attending an event because they are either too far away/too close and or too centrally located or too much to the side with respect to the source emitting the sound.
To this must be added the fact that numerous fans of the different musical genres are usually very discerning in terms of clarity of sound and wish to listen to melodies with increasingly higher acoustic qualities, which sometimes cannot be provided. So much said, it is easy to understand that the above-mentioned drawbacks are amplified in all those circumstances in which the sound propagates outdoors, as often occurs for music concerts staged in a stadium or in a park. Object of the Invention The main aim of this invention is to find an acoustic device for listening to sounds and noises which, in a practical, easy and functional way, allows listening to the sounds and noises that propagate in the surrounding environment with a clearly superior acoustic quality, above all in terms of the clarity of the sound perception.
Another object of this invention is to identify an acoustic device for listening to sounds and noises that allows overcoming the above-mentioned drawbacks of the state of the art as part of a simple and rational solution, that is easy and effective to use and inexpensive.
The above objects are achieved by this acoustic device for listening to sounds and noises, characterized in that it comprises conveyor means for conveying the sound suitable for collecting the sounds coming from the surrounding environment to a user and directing them into at least an ear of said user, and supporting means for supporting said conveyor means suitable for supporting said conveyor means near said ear of the user.
Brief Description of the Drawings
Other characteristics and advantages of this invention will appear more evident from the description of some preferred, but not sole embodiments, of an acoustic device for listening to sounds and noises, including but not limited to those shown on the attached drawing tables in which: the figure 1 is a perspective view of a first embodiment of the device according to the invention in operating configuration; the figure 2 is a front view of the device in figure 1 in operating configuration; the figure 3 is a view from above of the device in figure 1 in operating configuration; the figure 4 is an axonometric view of the device in figure 1 ; the figure 5 is an axonometric view of a second embodiment of the device according to the invention; the figure 6 is an axonometric view of a third embodiment of the device according to the invention; the figure 7 is an axonometric view of a fourth embodiment of the device according to the invention.
Embodiments of the Invention With particular reference to such illustrations, globally indicated by 1 is an acoustic device for listening to sounds and noises; for simplicity of exposition in this treatise the sounds and the noises are to be considered as being totally equivalent the one with the other.
The device 1 comprises conveyor means 2 for conveying the sound, suitable for collecting the sounds coming from the surrounding environment to a user 3 and directing them into at least an ear 4 of the user 3. In the particular embodiments of the invention shown in the illustrations, the conveyor means 2 consist of two shaped baffles, that can be positioned close to both the ears 4 of the user 3.
Other embodiments cannot however be ruled out in which the shaped baffles 2 are one only and dedicated to listening by only one ear 4. In detail, the shaped baffles 2 are concave, auricle-shaped and, in point of fact, make up a sort of extension of the auricles of the ears 4.
Usefully in fact, in operating configuration, the shaped baffles 2 are arranged so their concavity is substantially turned to the front of the user 3, i.e., directed towards the environment in front of the face of the user 3 so that, depending on which way he/she turn his/her face, the shaped baffles 2 permit collecting the sounds propagated in front of him/her.
The shaped baffles 2 are mounted on supporting means 5 which advantageously are associable with the head 6 of the user 3 and are suitable for supporting the conveyor means 2 close to the ears 4 of the user 3. Different embodiments of the supporting means 5 are possible.
In a first embodiment shown in the figures 1 to 4, for example, the supporting means 5 consist of a ring element that can be fitted around the head 6 of the user 3 and which has two opposite extremities 7 associable at the top with the shaped baffles 2. Usefully, the ring element 5 can be adjusted in length.
The ring element 5, in fact, comprises a main body 8 and two small arches 9 associated sliding with the main body 8 and suitable for defining the opposite extremities 7 which couple at the top of the shaped baffles 2. Usefully, in this embodiment, the device 1 also comprises retention means 12 for retaining the conveyor means 2 on the head 6 of the user 3.
Such retention means consist, for example, of a substantially elastic lace connecting the shaped baffles 2 and which can be positioned around the head 6 of the user 3 on the opposite side of the ring element 8, i.e., underneath the chin of the user 3.
In a second embodiment shown in figure 5, on the other hand, the supporting means 5 consist of two temples 10, one for each shaped baffle 2, which can be placed around the ears 4 of the user 3 and are associated with the shaped baffles 2.
In this embodiment, therefore, the shaped baffles 2 are separated the one from the other and can be arranged in operating configuration in an independent way the one from the other, applying the respective temple 10 to one of the ears 4. In a third embodiment shown in figure 6, on the other hand, the supporting means 5 consist of a headgear 11, of the type of a cap, a hood, a helmet or the like, that can be fitted to the head 6 of the user 3.
In this embodiment, the shaped baffles 2 are fitted on opposite sides of the headgear 11 so that, once worn, the shaped baffles 2 are arranged on the ears 4 ofthe user 3.
In a fourth embodiment shown in figure 7, furthermore, the supporting means 5 are composed of a ring element 8 identical to the embodiment of the figures from 1 to 4, with the difference that it is associated with the rear surface of the shaped baffles 2 and is intended, in operating configuration, to be placed around the back of the neck of the user 3.
In this fourth embodiment, furthermore, the useful surface of the shaped baffles 2 can be adjusted in size, i.e., it is possible to change the dimensions of the surface of the shaped baffles 2 designed to collect the sound and convey it into the ear of the user 3. For this purpose, each shaped baffle 2 comprises a first portion 2a, that is substantially shaped like a ball slice and is associated with the small arches 9 of the ring element 5, and a second portion 2b, that is also substantially shaped like a ball slice and which is associated turnable inside the first portion 2a. In point of fact, the outer surface of the second portion 2b is sliding and slides on the inner surface of the first portion 2a.
Depending on the position taken by the second portions 2b with respect to the first portions 2a, therefore, the surface of the shaped baffles 2 can be extended and, at the same time, can be turned in the direction in which the sound is propagated, enabling the user 3 to regulate listening as required depending whether he/she is far/near and/or whether he/she is centrally positioned or to the side with respect to the sound emission source. In the embodiment in figure 7, moreover, the edges of the shaped baffles 2 that come into contact with the head 6 of the user 3 have a cushioning layer 13, made of rubber or other soft material.
The corners 14 of such edges, moreover, are rounded off and/or connected and, together with the presence of the cushioning layers 13, permit wearing the device 1 in a more comfortable way.
The cushioning layers 13 and the rounded off and/or connected corners 14 are only shown in the embodiment of figure 7, but other options are possible in which such solutions are also adopted in the embodiments described previously and shown in the other illustrations. Other embodiments of the invention cannot however be ruled out in which the supporting means 5 consist of a frame for glasses with which the shaped baffles 2 are associated close to the ears 4 of the user 3; such embodiment is not shown in detail in the illustrations but for the expert in the field it will in any case be easy to understand how to make this in the light of what has been previously illustrated and described.
Finally, other embodiments are possible in which, for example, the shaped baffles 2 and/or the supporting means 5 are made of a substantially transparent material, so as to also allow a clear view of the concert/show/lesson for the persons behind the user 3. It has in practice been demonstrated how the described invention achieves the proposed objects.
The invention thus conceived is susceptible to numerous modifications and variations, all of which falling within the scope of the inventive concept. Furthermore all the details can be replaced with others that are technically equivalent.
In practice, the materials used, as well as the contingent shapes and dimensions, may be any according to requirements without because of this moving outside the protection scope of the following claims.
