Definitions
- the fixed pole parts also comprise a central fixed pole part, situated in the longitudinal median plane of the body of the loudspeaker, and received in a longitudinal recess of the rigid internal part of the membrane.
- the elongated flat membrane consists of a rigid part, covered with an elastic film, and / or comprises such a film, the edges of which are fixed to the adjacent side faces or under the bottom of the speaker body, this attachment can be achieved by bonding or by mechanical pinching.
- the elastic film is itself linked to the rigid part of the membrane by gluing, or by overmolding, or even by a mechanical connection. The edges of the elastic film of the membrane can be fixed by gluing or by mechanical pinching on the adjacent side faces of the speaker.
- Figure 9 is a sectional view showing a mounting detail of the loudspeaker, in the application illustrated by Figure 8.
- the rigid part 8 of the membrane 7, in the form of a plate, is extended towards the inside of the body 1 by a longitudinal wing 11, extending in the longitudinal median plane P of the body 1 of the loudspeaker, between the two magnets 5 and towards the bottom 3, the whole of the rigid part thus having a "T" profile.
- the longitudinal wing 11 has a longitudinal recess 12, open towards the bottom 3, in which the central fixed pole part 4 is slidably engaged.
- a mobile electromagnetic coil 13, parallel to the membrane 7 and of very elongated profile, is carried by the longitudinal wing 11 which extends the rigid part 8 of the membrane 7.
- the two fixed magnets 5 are thus placed outside the moving coil 13 on either side of the two long sides of this coil 13.
- L electrical supply to the coil 13 causes the membrane 7 to vibrate, elastically suspended by its elastic film 9 from the fixed part of the loudspeaker, the deformation of the membrane 7 during vibration being symmetrical on either side of its average rest position.
- FIGs 4, 5 and 6 illustrate variants of the suspension of the diaphragm 7 of the loudspeaker, the structure of which is, for the rest, not modified.
- the membrane 7 proper is limited to its rigid part 8.
