摘要： A contact device (2, 10) consisting of a helical spring which is adapted for SMD mounting, and which is formed with a base portion (4, 12) adapted to be positioned on and attached to a contact face by soldering or gluing, and with a top portion (6, 14) adapted for handling with a tool (16) preferably associated with an SMD apparatus. This provides the possibility of achieving a generally better and less expensive contacting between components, such as acoustic transducers, batteries or the like and printed circuit boards by means of simple features. Constructing the contact device as a screw or helical spring provides a great safeguard against transfer of laterally directed forces or moments from the contact face which destroy the contact face and/or the solder connection with the printed circuit. A tool (16) for handling the contact device (2, 10) consists of a preferably vacuum-driven mounting pick-up with a central control mandrel (18) which fits internally in the top portion (6, 14) of the contact device (2, 10), and which has an enclosing, ring-shaped recess (20) adapted to the outer shape of the top portion (6, 14) of the contact device (2, 10).

摘要： An electrodynamic acoustic transducer has its diaphragm with a coil retained with respect to the magnetic system in discrete points along the periphery of the diaphragm, while the rest of the periphery of the diaphragm is not fixed. The diaphragm has tongues at its periphery which are thicker than the rest of the diaphragm, and which are retained between two ring-shaped engagement faces, which, in the preferred embodiment, are formed by a magnetic system which is arranged symmetrically on both sides of the diaphragm. The diaphragm has a flat coil with spirally wound windings, and the diaphragm with coil and termination is supplied integrally with a web of sheet or a film roll comprising a large number of diaphragms, making the diaphragm useful for mounting in the transducer by tape automated bonding.

摘要： An electro-acoustic communications unit (10) such as a mobile telephone and a telephone handset or headset. The unit has a receiver transducer (12) generating sound signals from a first side (15) of the transducer, and the sound signals are output from the unit through one or more openings (17) in the housing (11). The transducer (12) is secured to a structure of the unit with its first side facing away from that structure. The transducer can thereby be placed at any desired location in the unit including in particular other structures than the housing wall, and a volume in the housing is included in the sound path from the transducer to the user's ear. The telephone can thus be very compact and still be leak-tolerant.

摘要： An electroacoutic communications unit with a receiver transducer in a housing. The communications unit has accoustic connections both from the front side of the diaphragm of the transducer and from its rear side to the area inwardly of the face of the unit for engagement with a user's ear as well as to the area outwardly of this engagement face. These four acoustic connections constitute the four branches of an acoustic balance bridge with the transducer as a generator. This configuration is particularly expedient, as it is hereby possible to reduce the inner air volume in the communications unit behind the diaphragm of the transducer to a size which is without importance for the size of the telephone in practice. Furthermore, variations in the degree of tightness of the engagement of the communications unit with the user's ear will only influence the frequency characteristic to a very limited degree.

摘要： The present invention relates to a telephone handset using an acoustic low impedance receiver transducer. A good reproduction of the low frequencies is obtained by introducing a front cover (7) having pure acoustic ohmic connections (8, 14) from the front side of the transducer diaphragm to the space (9) within the handset house (2).

摘要： An electrical device with electrical terminals in the form of helically wound electrically conductive, resilient wire (25, 26), for electrically connecting the device to other electrical or electronic equipment. At least two of the helically wound electrical terminals (25, 26) are arranged one within the other, preferably coaxially. The device can be a component with resilient terminals that are suitable for contacting corresponding contact surfaces on a printed circuit board, or the device can be a printed circuit board with resilient terminals that are suitable for contacting corresponding contact surfaces on an electrical or electronic component. In particular, the device can be an electroacoustic transducer with a magnet system (11, 12, 13) with a central permanent magnet (11) and an air gap (14) peripheral to the magnet, where the magnet generates a magnetic field in the air gap, and a diaphragm (15) carrying a coil (16) in the air gap.
