  • Publication number: 20030139199
    Abstract: The invention relates to a method for manufacturing a cellular phone (200), and to a cellular phone manufactured using said method. In the manufacturing method according to the invention, the platform, which comprises the essential electronic components of the cellular phone, is manufactured using mass production technology. A working cellular phone (200) also includes electronic custom parts which are integrated in a structural element in the phone. A customer can modify the properties of his phone by replacing the structural element with another one which comprises different components. A custom part may also be changed by the customer himself.

  • Publication number: 20030003866
    Abstract: A method of wirelessly communicating between a first and second device is disclosed, as well as devices for carrying out the method. The method has the steps of: transmitting a first set of data from the first device to the second device using a radio signal; and transmitting a second set of encoded data from the first device to the second device using an acoustic signal. The first set of data comprises information related to the encoding of the second set of data.

  • Patent number: 6415034
    Abstract: The scope of the present invention is an earphone unit (11) to be mounted either on external ear (18) or in auditory tube (10), in which unit both a speech registering microphone (13) and a speech reproducing ear capsule (12) have been placed. The earphone unit (11) is suitable for use in connection with various terminal devices, in particular with mobile stations. When a user's speech is registered, the ear capsule signal (12′) containing disturbances is canceled utilizing methods based upon determining the transfer function between the ear capsule (12) and the microphone (13). A separate error microphone (14) is used for eliminating external sources of disturbances (17), such as noise. In order to improve the quality of speech and prevent problems caused by double-talk, signals (15′, 12′, 17′) are processed digitally utilizing e.g. band limitation and prediction of missing bands.

  • Publication number: 20020076041
    Abstract: The invention relates to a method in connection with an acoustic transducer, such as a microphone (1), for a communication device, such as a wireless communication device (4), in which method the acoustic transducer (1) is attached on a substrate (2), such as a circuit board, or integrated in the substrate (2), and the housing (5) of the communication device is formed of at least a first (5a) and a second part (5b). The substrate (2) is provided with one or more apertures (3a-3f), which partly surround the acoustic transducer (1) order to achieve a nearly floating attachment for the acoustic transducer (1).

  • Patent number: 6178249
    Abstract: The invention relates to a method for attaching a micromechanical microphone (1) to be used in connection with a mobile station to a substrate (2), in which a diaphragm (4) and back electrode (6) for the microphone (1) are placed within a distance of each other, wherein an air gap (7) is formed between the diaphragm (4) and the back electrode (6). An insulation ring (12) is placed between the microphone (1) and the substrate, wherein the back electrode (6), the substrate (2) and the insulation ring (12) define a back chamber (13). The microphone (1) is attached to the substrate (2) with fixing means (11a, 11b), wherein the volume (Vb) of the back chamber (13) is adjusted by adjusting the height of the fixing means (11a, 11b).
