摘要： A weight (23) is attached to the rear side of a magnetic circuit (25) of a speaker unit (22). The tip of a boss (37) that projects to the front side from the weight (23) is joined to the rear side of a center pole (27) of the magnetic circuit (25) with a bolt (38). Even if reactive force that is generated when an electrical signal is converted into mechanical vibration by the magnetic circuit (25) and a voice coil (29) and sound waves are emitted from a vibration plate (24) is transmitted to the magnetic circuit (25), the vibration of the magnetic circuit (25) is suppressed by the weight (23). In this manner, sound quality with a good transient characteristic can be obtained.

摘要： In a speaker apparatus equipped with a speaker unit (1) including a magnet (2), a frame (3) and a diaphragm (4), a speaker housing (10) has a substantially cylindrical shape, and also has such a structure that the speaker unit (10) is secured onto one end surface of the cylindrical shape of the speaker housing (10) so as to substantially cover the speaker unit (10) except for front and back surfaces of the diaphragm (4). Further, the speaker housing (10) has an opening (10c) in another end surface of the cylindrical shape thereof. A support bar (7) extends and has one end secured to a back surface of the magnet (2) of the speaker unit (1). Furthermore, a weight (13) is secured to another end of the support bar (7), and then, the weight (13) holds the support bar (7) in a substantially vertical direction and grounds the magnet acoustically and virtually, thereby attenuating and suppressing oscillation transmitted from the magnet (2) to the support bar (7).
摘要翻译：在配备有包括磁体（2），框架（3）和隔膜（4）的扬声器单元（1）的扬声器装置中，扬声器壳体（10）具有大致圆筒形状，并且还具有如下结构：扬声器单元（10）被固定在扬声器壳体（10）的圆筒形状的一个端面上，以便基本上覆盖扬声器单元（10），除了隔膜（4）的前表面和后表面之外。此外，扬声器壳体（10）在其圆柱形状的另一端面上具有开口（10c）。支撑杆（7）延伸并且其一端固定到扬声器单元（1）的磁体（2）的后表面。此外，将重物（13）固定到支撑杆（7）的另一端，然后，重物（13）将支撑杆（7）保持在基本上垂直的方向，并且在声学上和虚拟地将磁体接地，由此衰减并且抑制从磁体（2）传递到支撑杆（7）的振动。
