Definitions

  • the present invention relates to a loudspeaker for high frequencies.
  • a loudspeaker comprises a vibrating membrane generating sounds, said membrane being connected for this purpose to a mobile electromagnetic coil suspended in the air gap created by the pole pieces of a permanent magnet and supplied by a representative electric current. sounds to reproduce.
  • the present invention relates more particularly to a compression chamber loudspeaker. It is known that, unlike direct radiation loudspeakers, compression chamber loudspeakers do not radiate directly into the air, but through an acoustic horn. Such speakers therefore comprise a generally removable acoustic horn and a motor with a compression chamber.
  • the loudspeaker membrane is produced in the form of a rigid spherical cap, often metallic and fixed to the chassis of said loudspeaker by means of a flexible peripheral suspension.
  • the mobile electromagnetic coil is connected to the periphery of said membrane, between said membrane and said suspension, and, during a movement, it displaces said entire cap in the manner of an infinitely rigid piston. It will be noted that, by its flexibility, said suspension has the function of ensuring the displacement and guiding of the mobile part of the loudspeaker.
  • the membrane in a second embodiment, corresponding to a tweeter with compression chamber, the membrane comprises a rigid central annular part and a peripheral annular part also rigid, connected together along an annular junction located opposite the flag of said speaker. Said annular parts are further connected to the chassis of said loudspeaker by means of elastic suspensions, said elastic suspensions being formed by lines of softening concentric with said annular parts, and generally practiced in the latter. In this embodiment, the membrane also moves in the manner of an extremely rigid piston.
  • this embodiment has the major drawback that the membrane, whose surface is too small and whose suspension is too rigid, does not allow this loudspeaker to operate from 500 Hz.
  • the object of the present invention is to remedy these drawbacks. It relates to a loudspeaker for high frequencies, lighter at equivalent performance than the loudspeakers of the prior art and capable of being produced easily and at reduced cost, while making it possible to emit sound waves according to a very wide bandwidth, especially towards high frequencies, with improved efficiency.
  • the loudspeaker for high frequencies comprising a vibrating membrane comprising a central annular part and a peripheral annular part connected together along an annular junction situated opposite the waveguide of said loudspeaker. speaker, said membrane being connected at said annular junction to a mobile electromagnetic coil suspended in the air gap of the pole pieces of a permanent magnet and supplied with an electric current representative of the sounds to be reproduced, is remarkable in that said membrane is made of a flexible and elastic material so as to present a defined deformation during the movement of said electromagnetic coil, and in that said annular parts are curved and are directly connected by their free end to a fixed structure of said loudspeaker, the side convex of said annular parts being arranged opposite said waveguide .
  • the expression “flexible and elastic membrane” is understood to mean a membrane capable of deforming and capable of returning to its initial position after the stress applied to it has ceased.
  • the bulging of said annular parts can take any possible form, in particular that of an arc of a circle or that of a half-torus.
  • At least one of said annular parts is connected to said fixed structure so as to form air gaps with respect to said fixed structure.
  • said air knives have a thickness which decreases progressively towards the zone of attachment of the membrane to the fixed structure.
  • said air knives can be formed on one side or on both sides of the membrane.
  • At least one of said annular parts is provided with radial softening lines uniformly distributed over the periphery of said annular part, which makes it possible to increase the flexibility of the membrane.
  • This flexibility can be increased, according to another embodiment, by making at least on one of said annular portions radial slots uniformly distributed over the periphery of said annular portion and by closing said slots with a flexible and elastic resin .
  • said waveguide is a horn and said membrane and said electromagnetic coil constitute a compression chamber motor.
  • the loudspeaker for high frequencies 1 usually comprises an electromagnetic coil 3, connected to a one-piece vibrating membrane 4, suspended in the air gap 5 of the pole pieces 6 and 7 of a permanent magnet 8 and powered by an electric current representative of the sounds to be reproduced.
  • the above elements are produced symmetrically with respect to the axis X-X of said loudspeaker 1.
  • the membrane 4 is of the type comprising a central annular part 9 and a peripheral annular part 10 connected together along an annular junction 11 which is situated opposite a waveguide which, in this case, is shown in the form a flag 12.
  • the coil 3 is connected to said membrane 4 at this annular junction 11, directly facing the mouth of said flag 12.
  • said membrane 4 is made of a flexible and elastic material, as light as possible, for example a composite material or a polymer with a high Young modulus, so as to present a defined deformation during the movement of said electromagnetic coil.
  • said annular parts 10 and 9 are curved and are directly connected by their free end respectively 13 and 14 to a fixed structure specified below of said loudspeaker 1, the convex side of said annular parts 9 and 10 being located opposite said horn 12.
  • a displacement of the coil 3 results in a deformation in the membrane 4, which moves from the junction 11 towards the ends 13 and 14 and which causes a variation in the local pressure, generating sound.
  • this variation in pressure is created near the coil 3 and it is oriented in the same direction as the propagation of the deformation in the membrane 4, which makes it possible to have a high energy yield in this respect. which concerns the transformation of mechanical energy into acoustic energy.
  • the volume swept by the deformation of the membrane 4 can be greater than that swept by a rigid membrane of the same size moving in the manner of a piston, as is generally the case for known membranes.
  • greater sensitivity is given to the speaker 1.
  • the bulging of said annular parts 9 and 10 can take all possible axisymmetric forms, in particular that of an arc of a circle or that of a half-torus.
  • the free ends 13 and 14 of said annular parts 10 and 9 are fixed by being embedded between elements of the fixed structure of the loudspeaker 1, namely between said horn 12 and a fixing piece 15 for the end 13 and between a phasing part 16 and a fixing part 17 for the end 14.
  • said air knives 13A, 13B, 14A and 14B have a thickness which decreases progressively towards the attachment zone of the ends 13 and 14, which makes it possible to spread in the frequency domain the advantageous effects generated by these knives. 'air and specified below.
  • the phasing part 16 of generally conical shape, can be produced in a very simple and inexpensive manner.
  • this phasing piece 16 the fixing piece 17 and the pole piece 7 are connected together by means of a screw 18 of axis XX passing through a cylindrical bore practiced so suitable in these different rooms.
  • a screw 18 of axis XX passing through a cylindrical bore practiced so suitable in these different rooms.
  • other methods of attachment can be envisaged. It is the same for the unspecified fixing of the other parts of the loudspeaker 1.
