Abstract: An electroacoustic transducer, functioning as an acoustic pick-up or as a sound generator, has a housing having a bottom and a wall portion. A diaphragm is connected to the housing opposite the bottom and encloses a diaphragm volume. An electromagnetic system is arranged in the housing and has a coil connected to the diaphragm. The housing has at least one cutout cooperating with at least one projection provided on a device in which the electroacoustic transducer is to be mounted. The projection defines a passage between the diaphragm volume and a volume at the back of the housing and thus forms the main air passage.

Abstract: The loudspeaker comprises a cone (2) and a beading (4) attached to the cone (2). The beading (4) is composed of a sprayable plastic layer which is soft in its solid state. The manufacture of the loudspeaker is facilitated by a process in which an open negative mold (16) is used in which the cone (2) is arranged and immobilized. Following this, the plastic is sprayed into the open negative mold (16) and the beading (4) is formed as a soft plastic layer which attaches itself to the cone (2).

Abstract: The periphery of the diaphragm of a loudspeaker is mechanically connected to a diaphragm support or basket by a layer of acoustic dampening-adhesive material. The layer of acoustic dampening-adhesive material covers a sufficient portion of the surfaces of the diaphragm to dampen standing waves which would otherwise reflect from the periphery of the diaphragm. Thus, a unitary diaphragm mechanical termination-acoustic termination structure is formed.

Abstract: A loudspeaker including a diaphragm of rigid, self-supporting, foamed plastic material clamped at its peripheral portion to a speaker frame, without providing increased compliance at said peripheral portion, to generate sound by bending motion of said diaphragm, said diaphragm having a soft material such as foamed or unfoamed rubberlike material (e.g. natural rubber, synthetic rubber or rubberlike plastic material) applied on at least a part of the peripheral portion at at least one side thereof, said soft material having relatively high specific gravity sufficient to suppress divided vibration of the diaphragm in low frequency sound range.
