Method for producing a musical instrument and musical instrument obtained thereby

A method for producing a musical instrument, said musical instrument comprising a hollow and compressible body made of a flexible and elastic material, delimiting an internal cavity, an internal wall arranged inside said body in order to divide said internal cavity into two chambers, and a musical insert mounted through said internal wall in order to place said chambers in communication with one another and designed to emit a sound when passed through by an air flow, said air flow being generated by a mechanical pressure exerted on said body at the level of one of the chambers, in which method the body of said musical instrument is made, using a moulding technique, from an elastomer material shaped in a hollow production mould provided with a vent hole, the internal volume of said mould corresponding to the three-dimensional impression of said body, wherein said internal wall provided with a through-orifice designed to receive and hold said musical insert in position is produced separately, and wherein, prior to the step of moulding said body, said internal wall is added into said production mould such that the periphery thereof is overmoulded by said body during the moulding step, and wherein, after the moulding operation for said body, said musical insert is inserted into said body via the vent hole left in the external wall of said body by the vent of said production mould, in order to interlock same in the internal wall through said through-orifice and simultaneously hermetically seal said through-orifice, and wherein, after mounting the musical insert inside said body, said vent hole is closed by a plug in order to sealingly plug and hermetically seal said internal cavity, such that said musical insert is arranged inside said body, between the two chambers so as to communicate solely therewith, without any communication with the environment external to said musical instrument.
