Definitions

• the present invention relates to electro-acoustic devices that transmit sounds into a person's ears.
• It relates more specifically to the transmission of acoustic signals in a noisy environment.
• the hearing system When in a noisy environment, for example inside a helicopter, an airplane or on a construction site, the hearing system must be protected from the point of view of pressure and sound level.
• a headset In order to meet the dual requirement of the protection of the auditory system and the transmission of electro-acoustic signals, a headset is used in which are incorporated loudspeakers that are arranged in front of the ears.
• the problem that the present invention proposes to solve lies in improving the quality of the transmission of electro-acoustic signals in a noisy environment.
• the solution of the aforementioned problem consists of an earpiece which comprises an earphone and connection means for connecting said earpiece with an electro-acoustic source.
• the atrium according to the invention is characterized it includes an acoustic filter and its external shape adapts perfectly to the crown of the ear and the external auditory canal so as to ensure sufficient soundproofing with the external environment.
• connection means are adapted to establish a wired connection between the earphone and the electroacoustic source.
• connection means are adapted to establish a wireless connection between the earphone and the electro-acoustic source.
• the headset according to the invention consists of a flexible material in which are incorporated the earpiece and the acoustic filter.
• the invention also relates to an assembly consisting of a headset as described above in the context of a cable connection with the electro-acoustic source, a cable having one end attached to the earphone and the other end provided with a connector adapted to connect to a primary circuit for transmitting electro-acoustic signals.
• the assembly described above is integrated in a headset which comprises a loudspeaker and a primary circuit.
• the primary circuit being adapted to port the speaker with a distant electro-acoustic source.
• the assembly according to the invention is connected to the primary circuit so as to take the signals coming from the electro-acoustic source.
• the headset may also be provided with two speakers and the assembly may consist of two earpieces, each group consisting of a speaker and a headset being intended for an ear.
• the atrium according to the invention offers several advantages, it allows in particular ergonomic protection against noise in airplanes and helicopters, a clear perception of radio signals and alarms in the cockpit. The results show that the system provides considerable advantages over prior art devices.
• the headset according to the invention can advantageously be used in any noisy vehicle in motion (racing car, ). It can also be used by people in contact with vehicle drivers (mechanic on the tarmac, in the paddock, ).
• FIG. 1 represents an embodiment of a helmet according to the invention.
• FIG. 2 represents an example of a headset according to the invention.
• FIG. 3 shows a set of wired headsets according to the invention.
• Figure 5 shows the independence between the movement of the cable and that of the tip.
• the sound enters through a primary circuit which comprises a left speaker and a right speaker, the two loudspeakers. speakers preferably being part of a helmet.
• the device further includes a pair of ear cups connected to the primary circuit through a connector.
• each atrium comprises a miniaturized earphone and a filter. These two elements are incorporated in the atrium.
• the earphone is located in an active channel which allows the cable connection with the source of the signals.
• the filter is located in a passive channel: it allows the elimination of noises that can parasitize the signals. Thanks to the presence of the earphones in the ear canal, and advantageously the filter, the perception of the acoustic signals is considerably improved.
• the speakers can remain active. They may not be, or simply not exist.
• the connector allows the sampling of signals transmitted on the primary circuit.
• the sound arrival integrated into a headset, serves the left speaker and the right speaker.
• Cable selection - IEM advantage of coaxial / twisted pair
• the cut-off threshold is adapted to the pilot's safety (no suburban damage).
