[Detailed description of the invention] The present invention relates to a speaker using a metal
tight cap to extend high frequency characteristics, and in particular, prevents deformation of the
tight cap by an external force, high) to excellent in mountability. Ask what you are trying to offer.
In general, the speaker is configured as shown in FIG. 1 and is 1'7 '//'. '2-. That is, a plate 2
having a center ball 1 and a link-like magnet 3. Similarly, the frame 6 is coupled to the magnetic
circuit 5 constituted by the link-like upper plate 4, and the entire periphery of the diaphragm 60
is adhesively bonded together with the gasket 7). The coil 9 is connected, the middle portion of
this pois cari / v 9 is held by the tamper-10, and the tip of the pois cari / l '9 is inserted into the
magnetic gear tub 11 of the magnetic circuit 5 without eccentricity. A dust cap 12 is attached to
the central upper surface. In such a speaker, the higher the reproduced sound is, the more the
sound is generated from the central portion of the diaphragm 8 near the connecting portion with
the voice coil 9, but the center of the diaphragm 8 By sticking the dust cap 12 to the part, the
high region is cut and can not be reproduced. ??????? "18910" ░-"10115 /" is not so
desirable, but it is a big problem in the speaker of full band reproduction from bass to treble like
3 in full range. If high strength can be reproduced by bonding the breast cap 12 to the upper end
of the coil bobbin of pois cay lv 9 or by forming the tust cap 12 with a breathable material
formed of cloth, the upper end of the coil bobbin of pois cary v9 In the case of those that are
coupled to the ?design?, the problem of balance occurs and it can not be adopted in many
cases, and the third harmonic leakage distortion in the low range is greatly increased when the
breathable tight cap 12 is used. And as a drawback such as having Hi-Fi seventeen disadvantages,
it is possible to extend the high region as much as possible by using metal foil such as aluminum
of Young's modulus as the tight cap 12 as a full range speaker Configurations are also being
developed. However, in this configuration as well, the high frequency is considerably higher than
that in the case where the thruster and the 'y-p 12 are not provided. ???? ????? There
is a drawback such as 1-5 ', -1' easy to form and 4 which significantly reduces the appearance
quality. The present invention is intended to eliminate the above-mentioned conventional
drawbacks, and aims to provide a speaker capable of significantly reducing the high-frequency
cut by using a reinforcing body and preventing deformation due to external force of the thrust
cap. It is a thing.
Hereinafter, an embodiment of the present invention will be described with reference to FIG. 2
and FIG. The overall structure of the speaker is the same as that shown in FIG. 1, and here, the
features of the present invention will be mainly described. In FIGS. 2 and 3, reference numeral 13
denotes a reinforcing member which is light and has a high Young's modulus and is made of a
light metal or a synthetic resin. This reinforcing member 13 is a ring-like portion coupled to the
upper inner surface of the coil povin 9a of the voice coil 9. 14 and a crosspiece 16 of four trees
which incline upward from the ring-shaped part 14 toward the center, and the upper surface is
curved at the center of the aggregate of the crosspieces 16. Bonding to the metal dust cap 12
and a portion 16 are provided. The diameter of the connecting portion 16,] ? ? is appropriate
for the diameter of the dust cap 12 from ? to 5 ░, and the bonding between the connecting
portion 16 and the dust cap 12 is performed using an adhesive. Although it is also preferable, it
is easier to control the disturbance of the characteristic in the high region by using the adhesive
resin. With such a configuration, the vibration of the voice coil 9 is the coil bobbin 9a, the 1'1
body 13. Since the signal is directly transmitted to the thrust cap 12, the attenuation is much
smaller than in the case of transmitting to the thrust cap 12 through the diaphragm 8 having a
large internal loss, and the high region is not cut. In addition, since resonance can be provided at
an appropriate frequency depending on the shape, material, and material thickness of the
reinforcing body 13, it is possible to create a peak in the high region, which can be a sound
preferable for hearing, etc. There is also the effect that you can freely control the sound quality.
Furthermore, since the bonding portion 16 of the hard reinforcing body 13 is attached to the F
cap of the thrust cap 12, the deformation when pressing with a finger is also significantly
reduced in the evening, and the appearance quality is improved You can also measure it. As the
speaker of the present invention has a simple reinforcing body as in 6 or more, the high band is
not cut even when using a Kosoku tast cap, and the dust cap is deformed and deformed by an
external force. In addition, it is extremely superior in terms of characteristics and is of great
practical value.
