    摘要: Device in acoustic transmitters comprising an elastic tubu­lar shell (1), such as a diaphragm, at least one driving member arranged inside said shell for generating an os­cillating movement of the shell, and pressure rods (5,6) ar­ranged inside the shell and in the axial direction for transmitting the movement of the driving member to the shell. According to the invention the driving member com­prises a body (6) with opposite recesses (13,14,15) into which driving rods (16,17,18) are inserted. One end of each driving rod is attached to a respective pressure rod (4,5) which directly influence the shell (1), and the other end of each driving rod makes contact with the bottom of the re­spective recess.

    摘要: A flextensional tranducer driven by magnetically biased rare earth rods (31). The rods (31) are arranged in stacks with rare earth magnets (34) mounted on each end of each stack for providing the bias field. The rods (31) are slotted to reduce eddy currents and surrounded by a slotted drive coil (32) with a slot (32a) in the coil bobbin. The ends of the flextensional shell associated with the shell major axis have a full radius curvature which stiffens the shell ends so that the axial bias and drive forces will not break the rare earth magnets (34) in flexure.

    摘要: The invention relates to a sound transducer (10; 10a to 10f), comprising a diaphragm (11; 62) and at least one piezo actuator (20; 20a; 40) which is arranged in operative connection with the diaphragm (11; 62), wherein the direction of vibration (25) of the piezo actuator (20; 20a; 40) is arranged at least substantially perpendicular to the direction of vibration (13) of the diaphragm (11; 62), wherein at least one lever element (16; 16a; 16b; 17; 17a; 17b; 48; 48a; 49; 49a; 68, 69) is arranged between the diaphragm (11; 62) and the piezo actuator (20; 20a; 40), connecting the diaphragm (11; 62) with the piezo actuator (20; 20a; 40) and designed to transform vibrations of the piezo actuator (20; 20a; 40) into vibrations of the diaphragm (11; 62) and vice versa, and wherein a clamp connection is formed between the at least one lever element (16; 16a; 16b; 17; 17a; 17b; 48; 48a; 49; 49a; 68, 69) and the piezo actuator (20; 20a; 40). According to the invention, the clamp connection is formed in the region between an end face (23; 23a, 24; 24a) of the piezo actuator (20; 20a; 40) arranged in the vibration direction (25) of the piezo actuator (20; 20a; 40), and the at least one lever element (16; 16a; 16b; 17; 17a; 17b; 48; 48a; 49; 49a; 68, 69), and the piezo actuator (20; 20a; 40) arranged by means of the at least one lever element (16; 16a; 16b; 17; 17a; 17b; 48; 48a; 49; 49a; 68, 69) under an axial pre-tensioning force (F) acting in the vibration direction (25) of the piezo actuator (20; 20a; 40).

    摘要: There is provided a portable terminal capable of acquiring sound information successfully simply by being brought near to or into contact with the ear without the necessity of careful handling. The portable terminal includes at least a vibration member (12) having a first surface (12a) exposed to an exterior, a vibration element (14) operative to vibrate the vibration member (12) in response to an electric signal corresponding to sound information, and electronic circuitry (17) that outputs the electric signal, a difference in amplitude between individual places within the first surface (12a) of the vibration member (12) in a vibrating state being less than or equal to 60 dB in terms of a ratio of maximum value to minimum value of amplitude. A portable terminal can be obtained that is capable of acquiring sound information successfully simply by being brought near to or into contact with the ear without the necessity of careful handling.
