Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a speaker, particularly to a signal input portion of a speaker for use in a vehicle.

Conventional speakers, especially car speakers, are
As shown in the figure, a terminal C is provided in the window hole B of the frame A, and the cord D is connected to the tinsel wire E through this terminal C.
An audio signal is supplied to the voice coil F through the . However, since car speakers are installed in a narrow car body space, sufficient care must be taken when installing them to prevent the signal input parts, such as terminal C and tinsel wire E, from coming into contact with the car body or being hit by objects in the trunk. I needed to be careful.

In addition, in order to prevent the lead wire of the voice coil from breaking, the lead wire between the cone paper and the speaker frame is wrapped in a vibration-preventing material made of a soft material such as a sound-absorbing material. There was a device that only contacted the frame and cone paper but not the frame or cone paper (Utility Model 52).
-20829 Publication).

However, since the vibration prevention member that wraps around the lead wire according to the prior art is located between the speaker frame and the paper cone, when used as a car speaker, the vibration prevention member that wraps around the lead wire is There was a risk that external signal input parts such as tinsel wire could come into contact with the car body or trunk and be damaged. Furthermore, no consideration has been given to the waterproofness of these external signal input parts.

Therefore, the present invention aims to solve the above-mentioned drawbacks by pulling out a tinsel wire from a window hole formed in a speaker frame, connecting the tinsel wire to a connecting terminal formed on the back side of the frame, This connection terminal and tinsel wire are covered with a flexible cover along with the window hole of the frame, and the cord connected to the above connection terminal is pulled out through this cover to protect the external signal input part such as the terminal and tinsel wire. In addition, it is an object of the present invention to provide a speaker that can be made breathable or waterproof depending on the mounting location of the speaker.

Hereinafter, the present invention will be described based on the embodiments shown in the drawings. FIG. 2 is a sectional view of a speaker according to the present invention, and FIG. 3 is a perspective view showing the main parts of the speaker.

The speaker in the drawing is a car-mounted speaker, in which 1 is a magnetic circuit consisting of a magnet 2, a back plate 3, and a top plate 4, 5 is a voice coil, 6 is a diaphragm, 7 is a damper, and 8 is a cap. 9 is a frame, and 10 is a window hole formed in the frame 9. The mounting piece 11 protruding from the magnetic circuit 1 side of the window hole 10 includes a terminal plate 12.
is fixed, and two terminals 13a and 13b are attached to the terminal board 12. A tinsel wire 14 connected to the voice coil 5 is pulled out from the window hole 10 and connected to the terminals 13a and 13b. Reference numeral 15 denotes a cord for supplying audio signals, and the ends of the cord 15 are connected to the terminals 13a and 13b, respectively, and detachable connectors 16.
a, 16b are attached. 17 is a cover large enough to completely cover the window hole 10;
The cover 17 is made of an insulating material such as flexible resin. The cover 17 may be mesh-like instead of cloth-like. If the cover 17 is made in the form of a cloth, only that part will be in a closed state in terms of sound pressure, which may affect the sound quality, but if the cover 17 is in the form of a mesh, it can be kept open in terms of sound pressure like the other parts. . Also, when installing a speaker on a car door, it is usually installed with the terminals 13a and 13b facing down, so if the cover 17 is cloth-like, rainwater may accumulate on the cover 17, but if it is mesh-like, this will not happen. Not at all. The cover 17 can be easily attached using double-sided adhesive tape or the like. Further, the cord 15 is movably inserted into the hole 17a formed in the cover 17. 18 is the rear tray of the car.

Therefore, connect the connectors 16a and 16b to the terminal 13.
a, 13b, and then close the window hole 10 with the cover 17.
The audio signal is supplied from the cord 15 to the voice coil 5 via the tinsel wire 14 through the terminals 13a and 13b.

Note that the present invention is applicable not only to in-vehicle speakers but also to general speakers.

As described above, in the present invention, the tinsel wire 14 is pulled out from the window hole 10 formed in the speaker frame 9, and the connection terminal 1 is formed on the back side of the frame 9.
A tinsel wire 14 is connected to the terminals 3a and 13b, and the connection terminal and the tinsel wire 14 are covered with a flexible cover 17 together with the window hole 10 of the frame 9.
The cord 15 connected to the connection terminals 13a and 13b can be pulled out through the cord.

Therefore, the connection terminals 13a, 13b and the tinsel wire 14
The external signal input portions such as the speakers are protected, which simplifies installation on the vehicle body, and depending on where the speakers are installed, they can be made breathable or waterproof.
