摘要： A loudspeaker includes a light-emitting element, a frame, a magnetic circuit provided with a magnetic gap, a diaphragm, a voice coil bobbin, and a voice coil. The diaphragm has an inner circumferential end including an end face facing the light-emitting element, and a light guide having a reflecting surface formed thereon and provided at a position where light enters from the end face. The first end of the voice coil bobbin is joined to the inner circumferential end of the diaphragm, and the second end is inserted into the magnetic gap. The voice coil is wound around the second end of the voice coil bobbin. Light from the light-emitting element enters the end face of the diaphragm, is diffused by the light guide, and is reflected on the reflecting surface.

摘要： A tunable ribbon microphone having magnets positioned within a small gap in between pieces of opposite poles. A conductive ribbon placed in an air gap between the magnets by an adjustable ribbon holder structure. The adjustable ribbon holder structure includes two ribbon holders and a ribbon tension control. The ribbon holder can be fixed from one side by sliding on one side or sliding on both sides. The ribbon tension control adjusts the tension of the elastic ribbon. By turning the ribbon tension control, turning motion translate to linear motion and change the distance between the ribbon holders and alter the tension of the ribbon. Changing the ribbon tension also possible by different ribbon tension control mechanism by rolled or folded the ribbon in one side or both side of the microphone. The tunable ribbon microphone may have more than one ribbon, adjustable ribbon holder structure and ribbon tension control.

摘要： In an electrodynamic electroacoustic transducer, a diaphragm assembly including a diaphragm and a voice coil is attached to a unit housing accurately and easily. A peripheral portion of the diaphragm curves upward while forming a downward convex portion toward an end portion side thereof. In an opening edge portion of the unit housing, a support base portion contacting the downward convex portion of the diaphragm is formed and a concave portion which a peripheral end portion of the diaphragm engages with is formed in an inside surface. In the diaphragm, the downward convex portion is supported by the support base portion of the unit housing in the peripheral portion thereof, so that the peripheral end portion engages with the concave portion of the unit housing in a state in which the peripheral end portion has upward elastic force.

摘要： The present invention provides a loudspeaker which is excellent in acoustic characteristics such as frequency characteristics and distortion characteristics. Particularly, edge 1 is formed in such manner that a thickness of sectional shape in radial direction increases from inner periphery portion 12 toward outer periphery portion 13. Due to this structure, a mechanical impedance of edge 1 against diaphragm 2 is decreased and bad influences on a vibration mode of the diaphragm are suppressed, and also, vibration energy is absorbed by the thick portion of the outer periphery portion, thereby suppressing standing waves of the diaphragm. The structure increases an efficiency of the medium and high frequency range sounds radiated from the loudspeaker, and further, greatly contributes to improve frequency characteristics, nonlinear distortion characteristics, and transient characteristics.
摘要翻译：本发明提供一种扬声器，它具有优良的声学特性，例如频率特性和失真特性。特别地，边缘1形成为从内周部12向外周部13的径向的截面形状的厚度增大。由于这种结构，边缘1对隔膜2的机械阻抗减小，并且抑制对隔膜的振动模式的不良影响，并且振动能量也被外周部分的厚部吸收，从而抑制驻波的隔膜。该结构增加了从扬声器辐射的中频和高频范围声音的效率，并且进一步有助于改善频率特性，非线性失真特性和瞬态特性。

摘要： A speaker apparatus has a frame to which a convex paper is attached. A bobbin with a voice coil is attached to the paper cone. A magnetic circuit is formed inside the frame. A damper suspending the bobbin is composed of a corrugation portion, which is positioned orthogonal to the bobbin in an inactivity of the speaker apparatus. The damper also includes a first leg portion extending forward along a vibration direction of the bobbin from an inner periphery end of the corrugation portion, and a second leg portion extending backward along the vibration direction of the bobbin from an outer periphery end of the corrugation portion. The first and second leg portions have substantially the same length.

摘要： An annular surround for a loudspeaker cone wherein a radial cross-section of the surround varies around the circumferential extent of the surround, so as to accommodate peripheral expansion or contraction of the surround by bending. Thus a trough shaped cross-section of the surround may vary sinusoidally with angle around the polar axis of the surround between a semicircular and semielliptical cross-section. The trough section may bland to an adjacent portion of the surround by a fillet which also varies sinusoidally in cross-section in phase with the variation of the trough.

摘要： An electrodynamic loudspeaker comprising a chassis, a diaphragm, and an actuator. The diaphragm is disposed within the chassis and has a front part and a back part. The actuator comprises a first actuator part connected to the diaphragm and a second actuator part connected to the chassis to cooperate with the first actuator part via an air gap. In order to obtain a large amplitude of the diaphragm a sub-chassis extends between the chassis and the diaphragm, a first flexible connecting element connecting the diaphragm to the sub-chassis, and a second flexible connecting element connecting the sub-chassis to the chassis.

摘要： Disclosed is a loudspeaker apparatus having at least one support surface provided therein adjacent to a complaint surround for providing lateral support thereto, the surround mounting the diaphragm of the speaker to a speaker frame for permitting longitudinal movement of the diaphragm with respect to the frame. The support surface may be used with a variety of surrounds. A second support surface may also be provided. The support surfaces may be contoured to achieve a desired response from their engagement with the surround. A negative air spring is formed from a pair of opposed support surfaces contoured to form a necked region therebetween for deformingly engaging a surround formed as a resilient member. The negative air spring negatively balances, or counterbalances the diphragm against the box pressures with the enclosure. The resilient member is formed as a tube for containing a fluid such as air therein. The pressure within the resilient member is controlled in response to a variety of parameters.
