Problems solved by technology

For this reason, the diaphragm usually has to be formed from a very strong and at the same time light material, such as a carbon fiber sheet, which increases the cost of the inherently advantageous construction of conventional loudspeakers for vehicle applications

Embodiment Construction

[0059] exist figure 1 A first embodiment of a loudspeaker 10 according to the invention is shown schematically in cross section in . A cone loudspeaker 20 is arranged in the housing 12 . The cone loudspeaker 20 has a cone diaphragm 22 which is connected via an elastic collar 24 to the upper edge of a frame 26 . The tray 26 is connected with its surrounding upper edge to the edge of the loudspeaker opening 14 in the acoustic baffle 16 of the housing 12 and is thus supported in the housing 12 . The cone loudspeaker 20 also has a voice coil driver 30 with a magnetic ring 32 designed as a permanent magnet, which surrounds a pole core 34 forming a magnetic gap (no reference numeral). The magnetic ring 32 is surrounded by a magnetic pole plate 36 . These components of the actuator 30 are firmly connected to the housing 12 via the frame 26, which is typically a metal or plastic frame.

[0060] The vibrating part of the exciter 30 is a voice coil former 38 with a voice coil throug...

Abstract

The invention relates to a loudspeaker comprising a housing, a cone diaphragm which is arranged in the housing and also an, in particular flat, covering which is arranged in or on the housing, is fixed at least in sections along its circumference, is arranged in front of the cone diaphragm in an opening direction of the cone diaphragm, covers the cone diaphragm and defines an intermediate space with the cone diaphragm and possibly the housing, and also comprising an actuator for generating vibrations. The invention further relates to a motor vehicle comprising at least one corresponding loudspeaker and also to the use of at least one loudspeaker in a motor vehicle. According to the invention, the covering is formed entirely or at least partially in a central region in front of the cone diaphragm as a flat and uninterrupted flexible shaft diaphragm, wherein a portion of the actuator that vibrates in order to generate noise is mechanically rigidly coupled both to the cone diaphragm and also to the flexible shaft diaphragm, so that axial movements of the actuator are transmitted to the cone diaphragm and to the flexible shaft diaphragm in phase.

Description

technical field [0001] The invention relates to a loudspeaker comprising: a housing; a conical diaphragm arranged in the housing; a, in particular flat, at least partially fixed, in particular flat, arranged in or on the housing and along the circumference of the conical diaphragm A cover plate; and an exciter for generating vibration, the cover plate is arranged in front of the conical diaphragm in the opening direction of the conical diaphragm, the cover plate covers the conical diaphragm and is connected with the conical diaphragm and If necessary, the space is defined together with the housing. The invention also relates to a motor vehicle having at least one corresponding loudspeaker and the use of the at least one loudspeaker in a motor vehicle. Background technique [0002] The invention relates generally to the field of sound generation by means of loudspeakers and in particular to the field of sound generation in and on motor vehicles. In addition to purely playin...
