Description of the invention (1) Fluorescent range The present invention relates to an exciter. The present invention is more particularly related to a movable coil exciter that establishes bending wave vibration in a bending member to produce an acoustic output. The exciter can form a driver in a resonant plate speaker. The resonant panel speaker is described in International Patent Application WO97 / 09842 and the speaker is a well-known distributed mode speaker. The technical background is known from EP-Α-0 丨 6〇478. It provides a movable coil piston cone speaker driving unit. The unit includes a component mounting ring combined with a voice coil assembly and is suitable for connection by means of a coil. The rear hung arm and the piston-shaped conical membrane are connected to the sound coil. In the design of a known movable line 圏 -type exciter for driving a resonant plate type speaker, a magnet assembly is a flexible suspension member which can be arranged between the flange-shaped protruding portion of the magnetic cup and the outer part of the coil. Connected to a voice coil assembly, the flexible suspension member is formed of corrugated sections with cloth by known methods or with any suitable flexible or elastic material. The disadvantage of this configuration is that a cavity will be established between the periphery of the flange and the resonance plate, and the cavity can cause the air in which it resides to produce a dizzy mode in the acoustic frequency range. The cavity pattern is radiated from the periphery of the flange and produces unnecessary and difficult to absorb sound output. The improvement can be achieved by sealing the pole whip and the area between the plates in a void-free manner in the area of the sound coil, but the outer part of the flange will still generate a cavity mode in the acoustic frequency range = > in the ring gap of the magnet assembly The alignment of the coil is extremely important for performance. In addition to the large air gap will cause loss of effect, it is clear that even if the micro t: 丨 Home standard (CNS> A4 _21.

Description of the invention (2) The bias or eccentricity of the small voice coil will also cause it to shake in the gap, which cannot be limited in the design of a single suspension exciter. In an effective exciter The most important thing in the design is the strict limitation of the lateral degree of freedom of the sound coil, which makes it difficult to reduce the gap size. The rubber sponge suspension system can produce the same vertical and lateral movement '. Therefore, increasing the lateral hardness can obtain a good coil pair. To increase suspension strength in the control board movement that restricts expansion at low frequencies. Obviously in some applications, small shakers are A suspension system is required so that it can move in and out of the gap freely, but it should be strictly restricted to move in other directions to prevent the gap from decreasing and increasing efficiency. The suspension system between the two planes will ensure that the piston movement does not tend to shake. But this basic requirement is cleverly turned into distributed mode speaker operation. Since the bending wave reflection needs to be "controlled" by the exciter, the suspension behind the sound coil (behind the magnet) should have a lateral margin, not on the magnet Front, so that side-to-side motion behind the voice coil "controls" a reflected bending wave that cannot push the magnetic cup to the side. Similarly, the front suspension element must be as close as possible to the resonant distribution mode speaker board SUMMARY OF THE INVENTION According to the present invention, a movable coil exciter for exciting a motor wave, that is, vibration, includes a magnet assembly defining a ring-shaped gap, and a voice coil assembly disposed in the ring-shaped gap. A mounting member, the exciter is mounted on the film by the member and the voice coil assembly is fixed on the mounting member, and an elastic suspension device Installed on the mounting member and coupled to the magnet assembly, so that the voice coil assembly is in the annular gap. ¾¾ 乂 soap is applicable in 0 national standard (CNS) Al specifications (210 X 297 mm) I. ---: --------- ^ -------- Order --------- M fi # First read the back; i sound?

There are different horizontal surpluses between the planes. The design has two additional features which can be easily aligned automatically & assembly, namely: (1) the pole shoe spring suspension (〗 3) can be inserted and fixed to the disc (3 〇), In order to make the exciter easy to assemble and disassemble, and (2) the sound coil system can be connected to the electrical contact (丨 6) on the dish (30), and then, when the point A vibrator contacts the surface of the board, it contacts the Loudspeaker board (not shown) The last shaker is installed with a conductive pad (not shown) that contacts the system. This configuration can reduce the wiring from the coil wire to the external cable and improve the balance of the magnet assembly. And further reduce the wiring on the board because the wires must be embedded in the board skin such as a thin copper sheet or a conductive paint layer. The principle of accepting the magnet cup from the magnetic shoe is to open the possibility of a very dense integrated lifting system, which is especially suitable for users of small shakers. Fig. 4 is an exciter (〗) as shown in Fig. 2 and Fig. 3 and how two circumferential slots in the magnet (2) make a simple bi-planar suspension system use a flat flexible gasket () 9), the holding piece is fixed between the magnet (2) and the master (6). This system facilitates the wide annular gap (24) between the carcass (2) and the tubular portion (4b). It should be noted that both the pole shoe (3) and the standing back (4a) are retracted into the center of the magnet (2). In this way, the entire exciter including the sound beam (7) is automatically aligned. In this example, the front suspension system has a soft sponge pad (丨 8) arranged concentrically on the plate (30) and the pole shoe (3) = one of the 4 shakers. The variation is illustrated in FIG. 5 , And its use-unmodified, that is, grooveless magnet (2). In this example, the cup is aligned by three automatics ------------- ~ equipment -------- order ---------- Λ (please first Read the notes on the back and fill in this page) ff company t: -10- 1 円 孓 standard (CNS> A1 Regulations ϋ ϋϊ ϋϊ 7_ 468353 Λ7 B7 V. Description of the invention (8) Steel parts (4 a), (4 b ) And (4c), the three steel parts are divided into suspension recesses, and the recesses are processed so that the suspension ring () 9) can be pre-assembled on the sound coil master (6). In this case, the upper tubular part (4c) is used for terminating the cup and the terminating end (21) is sharpened to improve the sound cavity effect, and the radon air gap (20) is only Established where the pole shoes need to be aligned. The shaker configuration shown in Figure 6 is usually similar to that shown in Figure 5. Although its smaller assembly can be used for larger shakers, it can be suspended from front to back. The fixed lateral alignment system derived from the distance between the suspensions is helpful for design. The maximum offset of the voice coil into the cup must be defined to prevent the front support of the pole shoe from hitting the board. In practice,-the sponge cushion pad system is available There, as shown in Figure 7, circle 6 The design of the example of the exciter can be further strengthened by sacrificing—the area of some magnets and the suspension (2 2) 1 μ magnet (2) < the periphery after contact with the ring sponge ring and the inner surface of the contact mold (6) The method is achieved. The correct selection of the sponge and its margin system can make the voice coil assembly ⑴ easy to push and automatically align with the assembly (rear. The voice coil assembly ($) before the line is borrowed from the standard boots and two hanging shoes (1 8) Alignment, the child suspension is arranged concentrically on the plate (30) and the pole shoe (3). The 3 plate (3 0) is supported by the mounting ring (1 0).
