class=\"dt-text-desc\">In essence, three components of active loudspeakers need to be investigated and further developed in this project: the sound-generating membrane, its drive and the amplifier electronics.<br \/>\nThe sound-generating membrane must be adapted to the needs of DEAs with regard to its mechanical properties, taking into account its acoustic properties.<br \/>\nThe DEAs themselves must be optimized for the desired frequency range in terms of their dynamic behavior and their nonlinear behavior must be accurately characterized. This information then also flows into the development of the amplifiers. In addition, the amplifiers must generate high voltages instead of the usually high currents. This necessitates the development of a new type of amplifier technology. Therefore, a close cooperation between the two research centres with their respective know-how (ZeMA: DEA development, integration and high voltage generation; Stamer: Acoustics of membranes and amplifier electronics) are required.<\/div><\/div><div class=\"hr-thin style-dotted\" style=\"width: 100%;border-top-width: 1px;\"><\/div><\/div><\/div><\/div><div class=\"wpb_column

lighter woofers with a significantly higher system efficiency will enable Stamer Musikanlagen GmbH to achieve a significantly higher market position in the field of active bass speakers. Since it can be assumed that many customers also want to buy the corresponding mid-high frequency units from the same manufacturer, a noticeable effect will also be expected on other product groups.<\/p>\n<p>In addition, a marketing of woofers to other manufacturers is also conceivable, which represents a new business area with enormous market potential, which is briefly presented in terms of volume in the following.<\/p>\n<p>On the part of the ZeMA, the research results are used to apply for and carry out further research projects. In addition, the resulting findings and laboratory setups are used for teaching (including final theses).<\/p>\n<p>Duration: 01.03.2019 - 28.02.2021<\/p>\n<p>Funded by:<\/div><\/div><\/div><\/div><\/div><\/div><div class=\"vc_row wpb_row vc_row-fluid wpb_animate_when_almost_visible wpb_slideInUp slideInUp\"><div class=\"wpb_column vc_column_container vc_col-sm-6\"><div class=\"vc_column-inner\"><div class=\"wpb_wrapper\"><\/div><\/div><\/div><div class=\"wpb_column vc_column_container vc_col-sm-6\"><div class=\"vc_column-inner\"><div class=\"wpb_wrapper\"><style type=\"text\/css\" data-type=\"the7_shortcodes-inline-css\">.shortcode-single-image-wrap.shortcode-single-image-09d5811b409d7013b87f89df5a25bcc4.enable-bg-rollover .rollover i,\n.shortcode-single-image-wrap.shortcode-single-image-09d5811b409d7013b87f89df5a25bcc4.enable-bg-rollover .rollover-video i {\n  background: -webkit-linear-gradient();\n  background: linear-gradient();\n}\n.shortcode-single-image-wrap.shortcode-single-image-09d5811b409d7013b87f89df5a25bcc4 .rollover-icon {\n  font-size: 32px;\n  color: #ffffff;\n  min-width: 44px;\n  min-height: 44px;\n  line-height: 44px;\n  border-radius: 100px;\n  border-style: solid;\n  border-width: 0px;\n}\n.dt-icon-bg-on.shortcode-single-image-wrap.shortcode-single-image-09d5811b409d7013b87f89df5a25bcc4 .rollover-icon {\n  background: rgba(255,255,255,0.3);\n  box-shadow: none;\n}<\/style><div class=\"shortcode-single-image-wrap shortcode-single-image-09d5811b409d7013b87f89df5a25bcc4 alignnone  enable-bg-rollover dt-icon-bg-off\" style=\"margin-top:0px; margin-bottom:0px; margin-left:0px; margin-right:0px; width:500px;\"><div class=\"shortcode-single-image\"><div class=\"fancy-media-wrap  layzr-bg\" style=\"\"><img decoding=\"async\" class=\"preload-me lazy-load aspect\" src=\"data:image\/svg+xml,%3Csvg%20xmlns%3D&#39;http%3A%2F%2Fwww.w3.org%2F2000%2Fsvg&#39;%20viewBox%3D&#39;0%200%20400%20113&#39;%2F%3E\" data-src=\"https:\/\/zema.de\/wp-content\/uploads\/2020\/07\/EFRE_KOM_rgbKl.jpg\" data-srcset=\"https:\/\/zema.de\/wp-content\/uploads\/2020\/07\/EFRE_KOM_rgbKl.jpg 400w\" loading=\"eager\" sizes=\"(max-width: 400px) 100vw, 400px\" width=\"400\" height=\"113\"  data-dt-location=\"https:\/\/zema.de\/en\/projekt\/auto-ibn%c2%b2\/efre_kom_rgbkl\/\" style=\"--ratio: 400 \/ 113;\" alt=\"\" \/><\/div><\/div><\/div><\/div><\/div><\/div><\/div>\n<\/div>","protected":false},"excerpt":{"rendered":"<p>BEAT - Bass loudspeaker with dielectric elastomer actuator drive In the by means of the European Regional Development Fund (in short: The ERDF-funded project investigates the use of dielectric elastomers as a drive for bass speakers.
