Abstract
Mejoras en dispositivo vibratorios electromecánicos caracterizadas por el empleo de un traductor electroacústico que consta de un imán permanente, una o más piezas polares, un extremo de tal pieza polar o de cada una de ellas, si hay más de una, colocadas adyacentes al diagrama y formando uno o más entrehierros respectivamente entre dicha una o más piezas polares y el diafragma, de forma que, tal una o más piezas polares trabajando en conjunto con el citado imán permanente para producir un flujo magnético en tal uno o más entrehierros y disponiendo además de una pieza o piezas polares adicionales que trabaje en conjunto con dicho imán permanente, por lo cual no todo el flujo que atraviesa el dicho uno o más entrehierros, atraviesa aquella parte o aquellas partes del diafragma que podría atravesar dicho flujo en ausencia de dicha pieza polar adicional o piezas polares adicionales.Improvements in electromechanical vibratory devices characterized by the use of an electroacoustic translator that consists of a permanent magnet, one or more pole pieces, one end of such pole piece or each of them, if there is more than one, placed adjacent to the diagram and forming one or more air gaps respectively between said one or more pole pieces and the diaphragm, such that such one or more pole pieces working together with said permanent magnet to produce a magnetic flux in said one or more air gaps and also having an additional pole piece or pieces that work in conjunction with said permanent magnet, whereby not all the flux that passes through said one or more air gaps, passes through that part or those parts of the diaphragm that could pass through said flux in the absence of said pole piece additional or additional pole pieces.
