DESCRIPTION

Series of headphones with wireless reception of a single sound source via low voltage FM transmitter with antenna for use in nightclubs.

The invention object of this specification refers to an unlimited number of helmet-type headphones equipped with ear pads, adjustable replacement fabric, rechargeable battery, connector, volume adjustment and wireless reception adjustment to a low-power FM transmitter with antenna connected to the mixing desk of a nightclub. It is intended to offer a novel solution to the problem of noise annoyances in discos or dance halls, advantageously allowing the participants in the party to listen and dance at will without the noise disturbing the neighbors or the pedestrians in the surroundings. to also allow them to individually adjust the volume of their auditions, thus obtaining a better hearing of the bass. Specifically, the system for the communication provided allows an improved hearing of the sound coming from the mixing table managed by the disc jockey and to which all the visitors of the disco are connected, being able to move and move without any inconvenience and even talk to each other just by unplugging one of the headphones. The invention can also incorporate a communication system through local networks, such as Wi-Fi and Blue Tooth.

In discotheques and music halls, one always encounters the disadvantage of the preponderance of bad bass sound. The sound mixers are expensively equipped, but the bass results are not at all encouraging. The sound often appears hazy and filled with alien noises. The sound technician's efforts are usually futile, he has no choice but to lower the volume of the bass in the mix, compensating in the overall sound with more volume from the kick drum. The challenges to achieving a good bass sound are many. Most musicians imagine their sound as being in a void, existing on its own, so what sounds good playing solo in auditions has very little to do with what is needed in audition rooms or discos. When marching bands practice and rehearse, little thought is given to how the instruments mix with each other and where each one occupies in the sound spectrum. Guitarists rave about adding bass to their sound, while bassists believe that every hissing detail of the sound of new strings must be relayed to listeners. To compensate, the drummers conscientiously cover the entire sound spectrum, from kick drum to hi hat.

The result is that no one listens properly in the discos and a career of volumes arises both in the rehearsal room and in the final auditions. Bass players can compete at best by producing clear, fat fundamentals enriched with clean media ... and not much else.

You could say that much of the sound of strings today is a mere chaos of high frequencies. In the disco mixer, guitar, cymbals, and other sources of high frequencies hide most of those highs. Trying to work your way into the mix by emphasizing the mids and highs is not going to clarify the bass sound, because its harmonic content is mostly finger noise, the vibration of adjacent strings, and frets or blows.

Much can be gained by filtering the sound before amplifying it. Bass clarity is determined by the shape of the sound wave. Certain waveforms break through better than others.

Ten-inch speakers tend to project concentrated sound in a narrow strip and are not very good at filling large rooms with sound. Ten-inch two-speaker cabinets are better, albeit positioned at ear height or at an angle. It is convenient to use them from the side instead of pointing them indiscriminately at the public.

Bass requires most of the power in a sound system, so if all the power is used for the kick drum, reverbs, and vocals, the guitarist's low frequencies can't even begin to compete. The audience will go home with ringing in their ears and without hearing a single note from the guitarist.

But in addition to this inconvenience, the poor hearing of the general sound in nightclubs, these face in many cases a much higher one, the noise level that causes anger and even complaints to police stations followed in many cases of lawsuits. Before the courts because especially the sound of the bass, which produces vibrations in the speakers that go through all kinds of obstacles such as walls and other construction material, they do not let them sleep.

These drawbacks are avoided with the present invention, since a low-frequency FM transmitter with an antenna properly positioned to transmit the sound coming from the mixing desk to a series of headphones is used instead of the traditional sound system of the nightclub through loudspeakers. wireless. In this way each member of the audience has their own headphones and can adjust their volumes to their liking.

The use of headphones, and in particular that of a helmet, has long been widely known either for professional use at multilingual congresses or for language learning, as well as private use. They are also usually used in those cases in which each individual wishes to listen to a different ear canal without disturbing others, or in cases in which some prefer to watch TV and others to listen to the radio or simply read or chat with each other without being disturbed by the radio. . Lately, its use has also become widespread to talk from mobile phones, such as the so-called hands-free, and even to adapt to the computer. But its use has always been oriented to individualize the hearing well to choose

ES 2 315 084 A1 of the different channels the one desired by each listener, or simply so as not to disturb the people around you. But they have never been used collectively for club listening, with many headphones connecting to a single sound source, as it has always been considered absurd to use headphones when music can be heard directly from the speakers. Hence, the main novelty that this invention presents consists of listening to collective music individually, achieving on the one hand a better hearing and on the other a total absence of external discomfort.

The current state of the art presents different types of headphones of various shapes and designs, most of them for listening to radio or TV broadcasts, although there are also for listening to FM music and lately for the telephone and for the computer. The helmet calls are the ones that best adjust to the good reception of the stereophonic sound, presenting the possibility of adjusting the headphones.

To preserve hygiene and avoid sanitary problems, the invention provides, among other novel features, disposable covers made of cloth or other appropriate material that adapt to the headphones, being used only once by each user.

In order to facilitate intercommunication between the dance partner, either during the dance or while sitting or standing at the table or bar, the right headphones advantageously consist of a button-shaped switch that when pressed they leave said earphone without sound while the left one continues working. This allows them to talk to each other, go to the waiter to order a drink or request information from any other participant, while still listening to the music of the disco.

With the incorporation of a good part of the available technology, the aforementioned inconveniences are solved, proposing a new sound system that is particularly simple, reliable, practical and without affecting the noise pollution of nightclubs in urban centers, in addition to improving the acoustic conditions of participants.

Thus, the present invention consists of a helmet headset that is covered in its hearing area with a disposable single-use cover, the right earphone being provided with a switch that can be easily activated and deactivated by the user, allowing the user to speak with their partner or with any other party participant, as long as he also deactivates his, without stopping hearing sound through the left earphone. The headphones are also equipped with volume adjustment and tuning adjustment. The sound system includes at least one low-power FM transmitter with an antenna provided with a hook to be able to be hung on the wall at an appropriate height and distance for its best reception, connected by cable to the sound source, which is the table. disco mixes, the transmitter automatically switches on and off when a certain volume is reached by adjusting the volume on the headphones. The invention can also incorporate a communication system through local networks, such as Wi-Fi and Blue Tooth.
