Embodiment Construction

[0030] These drawings, especially figure 1 and 2 , shows the dynamic loudspeaker structure (reference number 1).

[0031] In general, this structure includes: stator-shaping member (reference number 2), diaphragm-shaping member (reference number 3) and elastically deformable member (reference number 4 ) for connecting all these members ).

[0032] In fact, as shown, the stator-shaping member, the diaphragm-shaping member, and the connecting member are formed in a single piece by micro-structuring / processing silicon chips (e.g., monocrystalline silicon), for example Silicon chips are based on SOI (silicon-on-insulator) technology, as shown in the figure.

[0033] Polysilicon is also contemplated.

[0034] Such as Figure 1-5 As shown in the respective drawings, the Figure 5 In fact, the connecting member (reference number 4 ) comprises connecting arms regularly distributed between the stator-shaping member 2 and the diaphragm-shaping member 3 .

[0035] For example, if ...

Abstract

The present invention relates to the field of electrodynamic speakers. Particularly, the present invention relates to an electrodynamic speaker structure having MEMS technology. More particularly, the invention relates to such a structure comprising stator-forming means, diaphragm-forming means, and resiliently shape-changing means for connecting such means.

Description

technical field [0001] The present application relates to an electrodynamic loudspeaker structure with Micro-Electro-Mechanical Systems (MEMS) technology. More specifically, the present application relates to a structure comprising: a stator-shaping member, a diaphragm-shaping member, and elastically deformable members connecting all these members. Background technique [0002] Loudspeaker structures known in the prior art are of the type described in "A Compact and Low-Cost MEMS Loudspeaker for Digital Hearing Aids (a compact and low-cost MEMS speaker for digital speakers)" by Sang-Soo et al. Journal of Biomedical Circuits and Systems) "volume3, No.5, October 2009). [0003] In this document, the diaphragm-shaping member takes the form of a polyimide film associated with a stator-shaping member made on the basis of silicon chips. [0004] Nevertheless, this membrane-shaping member structure has certain disadvantages, notably relating to the complexity of its production, i...
