DE102008007129A1 - Loudspeaker arrangement for use in motor vehicle, has sunshine roof, where one or multiple electrostatic surface loudspeakers are integrated or formed into roof interior within rear area of motor vehicle - Google Patents

Abstract

The loudspeaker arrangement (1) has a sunshine roof (10), where one or multiple electrostatic surface loudspeakers (2) are integrated or formed into a roof interior within a rear area of a motor vehicle. Additional loudspeakers (3,4) are arranged for front seats at front remaining roof interior, console or door area in the motor vehicle.

Description

The The invention relates to a loudspeaker arrangement in a motor vehicle.

From the DE 10 2006 045 385 A1 a loudspeaker arrangement in a motor vehicle is known, comprising at least one loudspeaker, wherein the loudspeaker can be controlled by at least one driver assistance system to generate acoustic warning signals with directional information, wherein the loudspeaker is designed as an electrostatic surface loudspeaker which is arranged in the headliner or forms the headliner , By means of the arrangement proposed there, a particularly powerful DVE system (digital voice enhancement) can be realized.

at Motor vehicles with panoramic roof or sunroof leaves However, the proposed concept is not implemented.

Of the The invention is therefore based on the technical problem, suitable Speaker arrangements in a motor vehicle with sliding roof or panoramic roof to create, by means of which a DVE system can be realized.

The Solution of the technical problem results from the objects with the features of claims 1 and 6 to 9. Further advantageous embodiments of the invention will become apparent from the dependent claims.

The Speaker arrangement in a motor vehicle with a sliding roof is designed such that in the detected area of the motor vehicle one or more electrostatic flat speakers in the headliner are integrated or form the headliner, wherein in the motor vehicle additional speakers for the front seats are arranged.

Preferably the extra speakers are left in the front Headliner and / or in the console and / or in the door area arranged. The front speakers are replaced by a Front sounded sound system controlled.

In In a further preferred embodiment, the additional Speaker arranged in the immediate vicinity of the head, preferably in a headrest and / or in a vehicle seat. Preferably are the additional speakers as electrodynamic Speaker trained.

In Another preferred embodiment is in one Sun visor at least one electrostatic flat speaker and at least one electrostatic microphone arranged so that in particular for the driver a hands-free device is realized.

The Speaker arrangement in a motor vehicle with panoramic roof designed such that in the side headrails of the vehicle interior trim electrostatic surface loudspeakers are arranged, wherein each vehicle seat can be sonicated individually, d. H. everyone Vehicle seat is at least a single electrostatic flat panel speaker or an area speaker segment.

In an alternative embodiment is in each headrest and / or in each vehicle seat an electrodynamic loudspeaker arranged.

In Another alternative embodiment is an extendable or extendable roller blind, wherein at least in the roller blind an electrostatic area speaker and at least one Microphone, preferably an electrostatic microphone integrated are. This can then be removed, for example, when making a call or extended, the latter also being automatic can, for example, when a telephone connection is established.

In Another alternative embodiment is on or on the edge of the panoramic roof vibration speaker or Flexural wave loudspeakers arranged by means of complex transfer functions be controlled so that by beamforming the speakers are aligned with the individual vehicle seats.

The various alternative solutions for a motor vehicle with panoramic roof can also play with each other be combined.

The Invention will be described below with reference to a preferred embodiment explained in more detail. The only figure shows one schematic speaker arrangement for a motor vehicle with sunroof.

The speaker arrangement 1 for a motor vehicle with sliding roof 10 includes an electrostatic flat panel speaker 2 for the rear area of a motor vehicle, wherein the electrostatic surface speaker 2 is integrated into the headliner or forms the roof lining. Furthermore, the speaker assembly includes 1 at least two electrodynamic speakers 3 . 4 for the driver's seat and the passenger seat, which are integrated, for example, in the respective headrest. Preferably, it is provided that each vehicle seat two electrodynamic speakers 3 . 4 are assigned, namely one for the left side and egg for the right side. The electrostatic flat speaker 2 is preferably formed segmented or is composed of individual Flächenlautsprechersegmenten, wherein the segments can be controlled independently of each other. In the 1 is for reasons of clarity only one control line 5 shown. The electrostatic flat speaker 2 and the electrodynamic speakers 3 . 4 be from the same audio source or sound system 6 driven. Due to the fact that the signal voltages of electrostatic flat panel speakers 2 usually many times higher than electrodynamic loudspeakers 3 . 4 , is a transformer circuit 7 provided that the output voltages of an audio amplifier of the sound system to the correspondingly high voltages for the electrostatic flat panel speakers 2 high sets.

Next to the speakers 2 - 4 also microphones for the individual vehicle seats may be provided.
