  • Patent number: 7113813
    Abstract: A portable communication terminal employs an electro-acoustic transducer having openings on the housing. The openings of the transducer are coupled to a housing of the terminal or acoustic pipes unitarily formed with the housing of the transducer. An opening of the acoustic pipe faces an opening provided in the housing of the terminal. The terminal uses a transducer including a diaphragm, a cover closely jointed to an outer periphery of the diaphragm and facing a front face of the diaphragm, and a frame provided at a rear face of the diaphragm. The terminal and the transducer consume less power and yet radiate greater output sound pressure with smaller bodies. They can deliver sound from a display section, so that a user accepts the sound normally.

    Abstract: Apparatus for reducing the sound pressure level (SPL) heard by a user of a mobile terminal, such as a cellular phone, when listening with an ear sealed to the mobile terminal and for providing adequate sound when the ear is not sealed to the mobile terminal. Some sound is laterally ported away from the ear-sealing region on the terminal such that the SPL heard with a sealed ear may be controlled to be within regulatory requirements. The need for mechanical or proximity switches may be reduced or eliminated. Adequate SPLs are provided when the ear is not sealed to the device by the combined use of distal and central ports. Excessive SPLs may be prevented for sounds such as alert signals.

  • Patent number: 6990197
    Abstract: An improved hands-free speaker telephone designed to provide high-quality sound in a relatively small instrument, while at the same time avoiding acoustic shock to a user pressing the device too closely to an ear. If a speakerphone is mistaken for an ordinary portable or cellular phone, or simply out of misguided habit, a user may intentionally or inadvertently press the speaker against an ear. This action may subject the ear to an overly-loud audio event if the speaker begins producing sound, as hands-free speakerphone speakers are typically set to a much higher volume than those of ordinary phones. The effect, which is sometimes referred to as ‘acoustic shock’, is worsened significantly where the user actually succeeds in sealing the phone around the ear, as commonly (and harmlessly) occurs with standard (personal) phones. To avoid this undesirable phenomenon, the hands-free speakerphone is provided with a seal-proof speaker configuration.

  • Patent number: 6678504
    Abstract: A foldable handy phone of the present invention includes a receiver case and a transmitter case hinged to each other. A piezoelectric device or similar sounding means is accommodated in the receiver case. A through hole is formed in the surface of the receiver case that faces the transmitter case when the handy phone is folded up. The through hole is communicated to a portion accommodating the sounding means. A groove is formed in the above surface of the receiver case and extends from the open end of the through hole to the end of the receiver case opposite to the end hinged to the transmitter case. When the sounding means produces an alert tone in the folded position of the handy phone, the alert tone is radiated to the outside via the groove.

  • Patent number: 6658110
    Abstract: 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.

    Abstract: A wireless communication apparatus integrates a flat speaker (33) onto a liquid crystal display (12) or a rotational shield (3) of the apparatus. The flat speaker includes a vibrator (30) and a transparent vibrating membrane (31) which generates sound when the vibrator vibrates. The transparent vibrating membrane is mounted with a predetermined spacing over the liquid crystal display or over an inner surface of the rotational shield so as to gain a broader voicing surface. Thereby, by providing the flat speaker, the wireless communication apparatus can have a better audio effect.
