Patent number: 8189836Abstract: A method and hearing aid mold are provided for a hearing device with a first segment for insertion into the auditory canal of the user, a second segment, which projects into the concha of the user when inserted, and a vent, which runs from the first segment into the second segment. A vent opening, which may be enclosed by a titanium ring, is directed in the second segment toward the outer ear of the user, so that an exchange of air can be achieved between the auditory canal and the rear of the outer ear through an opening in the outer ear. Ventilation of the auditory canal from the rear of the outer ear reduces the risk of feedback.Type: GrantFiled: October 1, 2008Date of Patent: May 29, 2012Assignee: Siemens Medical Instruments Pte. Ltd.Inventors: Wai Kit David Ho, Wee Haw Koo

Patent number: 8139800Abstract: A hearing apparatus is to be provided, with which the battery can be exchanged in an almost wear-free fashion. Provision is thus made to magnetically attach a battery compartment or a battery holding device in the housing of the hearing apparatus or hearing device. The battery holding device is inserted into an opening in the housing. A detachable magnetic connection realized by magnetic elements thus exists between the housing and the battery holding device, the principle force component of which runs in the insertion direction. It is thus possible to dispense with plug or snap connections for instance.Type: GrantFiled: February 19, 2008Date of Patent: March 20, 2012Assignee: Siemens Audiologische Technik GmbHInventors: Wai Kit David Ho, Wee Haw Koo, Beng Hai Tan

Patent number: 8130993Abstract: The invention relates to a securing system for a receiver tube in a hearing device. The object of the invention is to provide a securing system for the receiver tube in a hearing device, which reliably prevents the occurrence of disruptive acoustic feedback and does not require adhesive to secure the receiver tube. This object of the invention is achieved with a hearing device, in particular a BTE hearing device, in which a receiver facility is disposed, wherein the hearing device has a connector piece, which is connected to the receiver facility by way of a receiver tube, in order to conduct an acoustic signal or acoustic signals generated by the receiver facility to an acoustic output of the hearing device, with the receiver tube being provided with a connecting element, which connects the receiver tube and the connector piece to each other in an essentially acoustically sealed manner.Type: GrantFiled: March 13, 2008Date of Patent: March 6, 2012Assignee: Siemens Audiologische Technik GmbHInventors: Wai Kit David Ho, Wee Haw Koo, Beng Hai Tan

Patent number: 8103031Abstract: A hearing device, in particular a hearing system, is designed more acoustically stable with regard to feedback as well as more mechanically stable with regard to external influences by a sound emission tube for direct connection to an output nozzle of an earpiece of a hearing device. The sound emission tube has an outer sheath made from a first plastic and an inner wall made from a second plastic that is more elastic than the first plastic. The outer sheath and the inner wall are produced by 2-component injection molding. The inner wall damps vibrations from the earpiece outward or shocks from the outside to the earpiece. Conversely, the outer sheath provides for the mechanical stability and the sufficiently rigid mounting of the earpiece.Type: GrantFiled: June 20, 2008Date of Patent: January 24, 2012Assignee: Siemens Medical Instruments Pte. Ltd.Inventors: Wai Kit David Ho, Wee Haw Koo, Wee Loong Ng

Patent number: 8098863Abstract: Hearing apparatuses and in particular hearing devices are to be designed smaller. To this end, provision is made to integrate an electrical control facility for controlling the hearing apparatus into the cover for covering a programming connection of the hearing apparatus. This multifunctionality of the cover allows installation space to be saved. It is particularly favorable if an actuating element of an electrical push button is mounted to the same bolt, to which the cover itself is also mounted.Type: GrantFiled: January 4, 2007Date of Patent: January 17, 2012Assignee: Siemens Audiologische Technik GmbHInventors: Wai Kit David Ho, Wee Haw Koo, Beng Hai Tan

Patent number: 8098865Abstract: An ear hook is to be able to be tightly attached to a hearing device housing in a simple fashion. To this end, provision is made for it to be possible to clip the ear hook onto the hearing device housing. One of the two parts; hearing device housing and ear hook has a sound outlet tube, which can be inserted into a corresponding opening in the other part. The two parts are detachably fastened to one another in an axial direction in respect of the sound outlet tube by means of a magnetic connection. The magnetic connection ensures that the two components are fitted tightly onto one another, though it enables said two components to rotate in respect of each other.Type: GrantFiled: February 21, 2008Date of Patent: January 17, 2012Assignee: Siemens Audiologische Technik GmbHInventors: Wai Kit David Ho, Wee Haw Koo, Beng Hai Tan

Patent number: 7853032Abstract: A hearing device with an audio shoe is to be designed in a simpler and less interference-susceptible manner. To this end, provision is made for an audio shoe to comprise contact springs of such type that directly contact the circuit boards of a hearing device. A contact intermediate piece between the audio shoe and the circuit board of the hearing device can thus be dispensed with. Furthermore, contact problems caused by the intermediate piece can hereby be avoided and the assembly cost for the hearing device reduced.Type: GrantFiled: August 29, 2006Date of Patent: December 14, 2010Assignee: Siemens Audiologische Technik GmbHInventors: Markus Heerlein, Wai Kit David Ho, Thomas Kasztelan
