摘要： A speaker which is thin but which is capable of providing high-fidelity reproduction and ensuring a suitable level of sound pressure even when it is brought close to a wall. A closed chamber is formed behind one part of a disphragm mounted in an enclosure, and an open chamber is formed behind another part of the diaphragm. At least one voice coil driver unit is connected to the diaphragm. The phase difference between sounds radiated from the front and rear surfaces of the diaphragm is increased as large as possible by using an acoustic duct for the sound radiated through the open chamber, thereby minimizing cancellation of sounds and improving the sound pressure level.

摘要： A diaphragm for loudspeakers comprises chitin as a natural high polymeric material having a large value of Young's modulus and kraft pulp having large mechanical internal loss. Therefore, the deformation and the partial vibrations of the diaphragm during diaphragm operation do not come out due to the use of the chitin, because the flexural rigidity of the diaphragm is considerably large. Mechanical internal loss is also large owing to the use of the kraft pulp. As a result, it is possible to obtain a loudspeaker which has little fluctuation in frequency response, and which provides a superior sound pressure-frequency response, a superior distortion factor and a superior phase response.
摘要翻译：用于扬声器的隔膜包括甲壳素，其具有大的杨氏模量值和牛皮纸浆具有大的机械内部损耗的天然高分子材料。因此，由于膜片的弯曲刚性相当大，因此膜片操作期间膜片的变形和部分振动由于使用甲壳素而不会出现。由于使用牛皮纸浆，机械内部损失也很大。结果，可以获得频率响应波动小的扬声器，并且提供优异的声压频率响应，优异的失真因子和优异的相位响应。

摘要： A sound reproducing apparatus for use in a vehicle having a speaker system constituted by at least one acoustic duct and a speaker unit disposed at a throat of the acoustic duct, an opening formed at the other end of the acoustic duct facing the passenger compartment of a vehicle. The apparatus is arranged such that, F0 and Fs are substantially equal to each other. Where Fs is the lowest frequency in a frequency range within which the imaginary part of the acoustic impedance at the sound radiating surface of the speaker system in the direction of the space within the passsenger compartment is zero and F0 is the low-range resonance frequency of the speaker system itself in the free space.

摘要： A piezoelectric speaker comprises a plurality of diaphragms, connecting components, and piezoelectric elements. The plurality of diaphragms are each formed by a laminated material in which a core layer made of an insulating material is laminated to skin layers each made of a conductive material so as to form the skin layers on both surfaces of the core layer. The connecting components each corresponds to a plate-shaped component of the insulating material and connects between at least two of the plurality of diaphragms. Piezoelectric elements are mounted on surfaces of the plurality of diaphragms, respectively. The plurality of diaphragms are insulated from each other such that separate voltages are applied to the piezoelectric elements mounted thereon, respectively.

摘要： A piezoelectric speaker improved in acoustic features by weight reduction of a diaphragm of the piezoelectric speaker without decreasing stiffness of the diaphragm or a coefficient of thermal expansion of surfaces of the piezoelectric speaker is provided. The diaphragm having placed thereon a piezoelectric element is made of a sandwich-laminate clad material using different materials. For example, surface materials made of 42 alloy each having a thickness of 10 μm and a core material made of aluminium having a thickness of 30 μm form a clad material having a thickness of 50 μm. The formed clad material is processed into an arbitrary shape to form the diaphragm of the piezoelectric speaker. With this diaphragm, it is possible to keep the stiffness and the coefficient of thermal expansion of the 42-alloy diaphragm having the thickness of 50 μm, and also achieve weight reduction by approximately 40%.
