Description
- The present invention relates to a vehicle-mounted speaker apparatus in which a network coil is fixed to a speaker frame by a tying band.
- In vehicle-mounted audio systems etc., because of a restriction of a vehicle body side mounting space and other factors, various kinds of vehicle-mounted speaker apparatuses having a multiway speaker system have been developed in which a resin terminal plate is attached to a speaker frame (which movably supports a vibration plate) of a speaker unit and network elements are attached to the resin terminal plate.
-
Fig. 1 shows aresin terminal plate 1 that is attached to a speaker frame and network elements 3 and 4 that are mounted on theresin terminal plate 1 in such a vehicle-mounted speaker apparatus. - In addition to the network elements 3 and 4,
input terminals resin terminal plate 1. A known structure for fixing such aresin terminal plate 1 to a speaker frame is such that the speaker frame is formed with female threads and theresin terminal plate 1 is screwed to the speaker frame (e.g.,JP-A-2004-187233 - The large network element 3 on the
resin plate 1 is a network coil (choke coil) and the small network element 4 is a capacitor or a resistor. Each of the network elements 3 and 4 is fixed to theresin terminal plate 1 in an exposed state (e.g.,JP-A-2001-251694 - The small and light network element 4 is fixed to the
resin terminal plate 1 by soldering lead wires to metal terminal parts that are fixed to theresin terminal plate 1. However, for the larger and heavy network coil 3, merely soldering lead wires cannot provide fixing strength that is sufficiently high to sustain vibration of a vehicle body. As shown inFig. 1 , one conventional measure is such that the network coil 3 is tied and fixed to theresin terminal plate 1 by means of atying band 9 that is wound around the network coil 3. - However, in the network coil fixing structure shown in
Fig. 1 using thetying band 9, the binding ability of thetying band 9 is effective only in a limited region in the axial direction where it is wound around the network coil 3. For example, bothends 3a and 3b of the network coil 3 cannot be fixed firmly. - As a result, vibration or the like occurring while a vehicle is running may cause both
ends 3a and 3b to shake in the direction perpendicular to the center axis of the coil 3 as indicated by arrows A and B, possibly resulting in deterioration in the acoustic characteristics or damage (e.g., fatigue) of an electric connecting portion or the like. - Further, since the network coil 3 is mounted in an exposed state, it may be stained in such a manner that water condensation occurs on, for example, the inner surface of a vehicle body panel on which the speaker apparatus is mounted and resulting water droplets fall onto and cover the network coil 3.
- Still further, where the
tying band 9 is fixed to theresin terminal plate 1, an installation space large enough to mount the network coil 3 on theresin terminal plate 1 needs to be secured. This is a factor of causing increase of the size of theresin terminal plate 1, which in turn is a factor of preventing realization of a compact vehicle-mounted speaker apparatus or causing a cost increase. - It is an object of the present invention to provide a vehicle-mounted speaker apparatus in which deterioration in the acoustic characteristics and fatigue of an electric connecting portion or the like due to vibration of a large network coil can be prevented by fixing the network coil (including both its ends) firmly and the network coil can be prevented from being covered with droplets-turned water and thereby stained. Another object of the invention is to provide a vehicle-mounted speaker apparatus which can be made more compact and reduced in cost.
- According to an aspect of the invention, there is provided with a vehicle-mounted speaker apparatus including: an assembly including: a network coil having an outer circumferential surface; and a tying band being attachable to the outer circumferential surface of the network coil along a longitudinal direction of the network coil; and a heat-shrinkable tube into which the network coil and the tying band can be at least partially inserted, wherein the network coil is fixed to the speaker frame by tying the tying band to the speaker frame.

speaker apparatus 31 according to this embodiment is equipped with amagnetic circuit 5, aspeaker frame 33 to whose rear portion themagnetic circuit 5 is attached, a cone-shaped vibration plate 37 to whose outer circumferential portion anedge 35 having a generally semicircular cross section is connected, a cylindricalvoice coil bobbin 11 which is attached to an inner circumferential flange of thevibration plate 37, avoice coil 12 which is wound around thevoice coil bobbin 11, aresin terminal plate 25 on which network elements are mounted, and anetwork coil 41 as a network element. - The
magnetic circuit 5 is composed of ayoke 15 having a structure that acylindrical center pole 15b projects from a disc-shaped plate 15a at the center, a ring-shaped magnet 16 which loosely fitted with thecenter pole 15b, and a ring-shapedtop plate 17 which is loosely fitted with a front portion of thecenter pole 15b in such a manner that themagnet 16 is sandwiched between thetop plate 17 itself and theplate 15a. Thetop plate 17 is fixed to the rear end of thespeaker frame 33. - In the
magnetic circuit 5, the gap between the inner circumferential surface of thetop plate 17 and thecenter pole 15b is a magnetic gap in which thevoice coil 12 is disposed. - The
voice coil bobbin 11 which is fixed to the inner circumferential flange of thevibration plate 37 is connected to thespeaker frame 33 via acorrugation damper 39 in which peaks and bottoms are arranged alternately and concentrically in the radial direction, whereby thevoice coil bobbin 11 is suspended so as to be movable in the axial direction of thecenter pole 15b. - The
edge 35 is fixed to the outercircumferential portion 33a in such a manner that an attachment flange 35a as an outer circumferential portion of theedge 35 which is located outside thevibration plate 37 is adhered to an outercircumferential portion 33a (located outside a speaker mounting opening (diameter: d1) of a speaker mounting plate 21) of thespeaker frame 33 and is held between the outercircumferential portion 33a and apacking 47 which is fixed to the outercircumferential portion 33a. - A
flange 35b as an inner circumferential portion of theedge 35 is bonded to the back surface of thevibration plate 37 and thereby rendered integral with thevibration plate 37. - In the
speaker frame 33 which is produced by press-forming a metal sheet, aflat portion 33b to which thecorrugation damper 39 is attached is located in front of arear plate 33e as a mounting portion for themagnetic circuit 5. Anattachment flange 33c to which theresin plate 25 is attached is integral (continuous) with theflat portion 33b. - The
attachment flange 33c is a flat plate extending outward in the radial direction from the outer periphery of theflat portion 33b, and is formed by cutting and erecting a portion of a plate material in a region where the opening of thespeaker frame 33 is formed. - The
resin terminal plate 25 is a resin plate that is fixed to theattachment flange 33c of thespeaker frame 33 by screwing or engagement using an engagement projection etc. Theresin terminal plate 25 serves as a mounting portion for terminal metal parts and small parts (e.g., resistors and capacitors) excluding thenetwork coil 41 among various parts that are necessary for forming a network circuit of the vehicle-mountedspeaker apparatus 31. - In this embodiment, the
network coil 41 which is necessary for forming the network circuit is fixed singly to thespeaker frame 33 by aresin tying band 42 rather than fixed to theresin terminal plate 25. - The structure for mounting the
network coil 41 on thespeaker frame 33 in the embodiment will be described below in detail. - As shown in
Fig. 4 , anassembly 44 in which theresin tying band 42 is fixed to thenetwork coil 41 is formed in advance by placing thetying band 42 adj acent to the outer circumferential surface of thenetwork coil 41 parallel with the longitudinal direction of thenetwork coil 41 and heat-shrinking a heat-shrinkable tube 43 in which thetying band 42 and thenetwork coil 41 are inserted. A state that thenetwork coil 41 is fixed to thespeaker frame 33 at a position close to theresin terminal plate 25 is established by winding and tying thetying band 42 of theassembly 44 around and to a cylindrical outercircumferential portion 33d of thespeaker frame 33. The outercircumferential portion 33d is located between therear plate 33e and theflat portion 33b at a position close to the rear end of thespeaker frame 33. - As described above in detail, in the vehicle-mounted
speaker apparatus 31 according to the embodiment of the invention in which thenetwork coil 41 is fixed to thespeaker frame 33 by thetying band 42, theassembly 44 in which thetying band 42 is fixed to thenetwork coil 41 is formed by placing thetying band 42 adjacent to the outer circumferential surface of thenetwork coil 41 parallel with the longitudinal direction of thenetwork coil 41 and heat-shrinking the heat-shrinkable tube 43 in which thetying band 42 and thenetwork coil 41 are inserted and thenetwork coil 41 is fixed to thespeaker frame 33 by tying thetying band 42 of theassembly 44 to a proper portion thespeaker frame 33. - Since the
tying band 42 that is placed adjacent to thenetwork coil 41 parallel with the longitudinal direction of thenetwork coil 41 is fixed to the outer surface of thenetwork coil 41 so as to be in close contact with the latter by means of the heat-shrinkable tube 43, the network coil 41 (including both its ends) can be fixed to thespeaker frame 33 firmly when thetying band 42 is wound around and tied to the proper portion of thespeaker frame 33. - Since the large network coil 41 (including both its ends) is fixed to the
speaker frame 33 firmly, thenetwork coil 41 can be prevented from shaking even if vibration occurs while a vehicle is running is propagated to thenetwork coil 41. This prevents deterioration in the acoustic characteristics and fatigue of an electric connecting portion or the like due to coil vibration. - Since the
network coil 41 is not mounted in an exposed state but surrounded by the heat-shrinkable tube 43, even if water condensation occurs on, for example, the inner surface of a vehicle body panel on which the vehicle-mountedspeaker apparatus 31 is mounted and resulting water droplets fall onto the heat-shrinkable tube 41, the water droplets do not come into direct contact with thenetwork coil 41 and hence thenetwork coil 41 can be prevented from being covered with water and thereby stained. - In the vehicle-mounted
speaker apparatus 31 according to the embodiment, thenetwork coil 41 is directly fixed to thespeaker frame 33 by winding and tying thetying band 42 directly around and to the cylindrical outercircumferential portion 33d of thespeaker frame 33. - Therefore, it is not necessary to secure an installation space for the
network coil 41 which is a large part on theresin terminal plate 25 which is provided on thespeaker frame 33 for mounting of the parts constituting the network circuit. The size of theresin terminal plate 25 can be made smaller accordingly, which can in turn make the vehicle-mountedspeaker apparatus 31 more compact and reduce its cost. - In the above embodiment, as shown in
Fig. 2 , the cylindrical outercircumferential portion 33d which serves as the mounting portion for thenetwork coil 41 recedes from the outer circumferential surface of themagnetic circuit 5 and defines a groove-like space. And this space is effectively utilized as amounting space for thenetwork coil 41 . This reduces the outward projection length of thefixed network coil 41 and thereby enables miniaturization of the vehicle-mountedspeaker apparatus 31 efficiently. - The mounting position of the
assembly 44 is not limited to the cylindrical outercircumferential portion 33d (above embodiment), and may be another portion of thespeaker frame 33 as long as an installation surface is secured that is sufficiently wide for mounting of thenetwork coil 41. However, to make the wiring between thenetwork coil 41 and the other network elements as short as possible, it is desirable that the mounting position of theassembly 44 be set near the position of theresin terminal plate 25. - The cylindrical outer
circumferential portion 33d is the best in this respect.
