Problems solved by technology

[0007] On the other hand, a drawback of using magnetic transducers for sound and / or speech bone conduction is that the user can clearly and realistically perceive the audio quality of said sound and / or speech
[0008] Considering that electromagnetic transducers for forming sound and / or speech bone conduction vibrations are used in conjunction with a helmet, their unsuitable miniaturization or small size does not pose too much of a problem, but, obviously, it does not apply Use in other situations

Embodiment Construction

[0029] Refer to the accompanying drawings, especially the figure 1 to attach Figure 6 , Reference numeral 1 denotes the whole electromagnetic transducer for forming sound and / or speech bone conduction vibration according to the present invention.

[0030] Described electromagnetic transducer 1 comprises a magnetic yoke, and it comprises:

[0031] The substrate 2 of ferromagnetic material has an elongated shape in a first direction X-X, so that two long sides 2b and two short sides 2b extending substantially parallel and respectively perpendicular to said first direction X-X can be defined on said substrate 2. Side 2a, according to the embodiment shown, said substrate 2 of ferromagnetic material has a rectangular shape;

[0032] The magnetic pole 3 protrudes axially from the central area of ​​the substrate 2 of the ferromagnetic material, and the magnetic pole 3 has an elongated shape perpendicular to the axis of the magnetic pole 3 in the first direction X-X;

[0033] The ...

Abstract

An electromagnetic transducer for generating vibrations for sounds and / or words bone conduction, comprises a magnetic yoke comprising a ferromagnetic material base plate (2), a magnetic pole (3), a voice coil (4) positioned around the magnetic pole (3), a pair of permanent magnets (5) positioned outside said voice coil (4) and a vibrating diaphragm (6) of ferromagnetic material supported by said non-ferromagnetic support means (7). Advantageously, such support means (7) are supported by said base plate (2) by means of fastening brackets (8), wherein theengage portions of said support means (7) project beyond said base plate (2) and exceed opposite ends of the base plate (2).

Description

technical field [0001] The invention relates to an electromagnetic transducer for forming sound and / or speech bone-conducted vibrations according to the preamble of claim 1 . Background technique [0002] Today, transducers of the above-mentioned type are becoming more and more popular compared to conventional types of headphones. That's because bone conduction technology allows users to listen to music, voice, and speech without plugging earphones into their ears or wearing annoying headphones. [0003] In fact, it is sufficient for electromagnetic transducers for forming sound and / or speech bone-conducted vibrations, such transducers are able to communicate with the bones in the head without being subjected to, for example, muscles or fat, etc. Specially protected parts of the soft tissue are in contact so that the user can hear sound and / or speech in a clear manner without being affected by external noise that can be perceived by the auditory organs. [0004] For exampl...
