[0003]
However, with the progress of the times, consumers have become increasingly concerned with
the tone and quality they hear.
Thus, in order to provide a favorable sound effect, most audio reproduction products are fitted
with units of different audio frequencies, for example by attaching a high frequency unit and a
low frequency unit, the corresponding audio frequency features Each treatment has enabled us
to provide even higher quality sound effects.
[0004]
Since the audio wavelengths emitted from different audio frequency units are different, the
arrangement relationship between the high frequency range unit and the low frequency range
unit is an important factor in order to avoid mutual interference between different audio
frequencies.
Therefore, how to provide high-quality sound effects by using structural design to prevent
mutual effects between different audio frequencies is an urgent task in the current industry. ing.

[0016]
In addition, referring to FIG. 4, it is a cross-sectional view of the earphone structure according to
the present invention. The presence of a pitch between the front sound guide 21 and the housing
wall 11 forms an annular sound guide 24 between the front sound guide 21 and the housing wall
11. The sound conduit 23 is located in the sound emission path 13, and the end of the sound
conduit 23 is provided with the sound emission port 231, and the sound emission port 231 is
close to the sound hole 12. Also, the sound channel 24 may be connected to the sound hole 12
so that the sound can be directed toward the sound hole 12 via the sound channel 24.
[0017]
The rear sound guiding portion 25 is a circular cover body, which is disposed concentrically with
the front sound guiding portion 21 and is separated from the sound hole 12 compared with the
front sound guiding portion 21. In addition, the width of the rear sound guide 25 is wider than
the width of the front sound guide 21, that is, the diameter of the rear sound guide 25 is larger
than the diameter of the front sound guide 21. The rear sound guiding portion 25 includes an
enlarged annular peripheral wall 251, an outer peripheral wall 252, and a second
accommodating portion 26, and the expanded annular peripheral wall 251 is connected to the
rear side of the first accommodating portion 22 in the radial direction and to the sound hole 12.
The outer peripheral wall 252 is connected to the outer periphery of the enlarged annular
peripheral wall 251, and the second accommodation portion 26 is located between the enlarged
annular peripheral wall 251 and the outer peripheral wall 252 and communicates with the first
accommodation portion 22. Further, a plurality of sound guide holes 253 are provided in the
enlarged annular peripheral wall 251, and the plurality of sound guide holes 253 communicate
with the sound guide path 24. In the present embodiment, the plurality of sound guiding holes
253 are equiangularly disposed and present an annular array form (FIG. 2).
[0018]
As shown in FIG. 4, in the present embodiment, the first speaker unit 30 can be a high-pitched
speaker unit, and is provided in the first accommodating portion 22 of the front sound
conducting portion 21. In the present embodiment, the first speaker unit 30 includes a chamber
31 and an output port 32. The chamber 31 is in the form of a circular chamber, and the
02-05-2019

peripheral wall of the chamber 31 is adjacent to the peripheral wall of the first accommodating
portion 22. The output port 32 is opened on one side of the chamber 31, and by matching the
position of the sound conduit 23, the sound signal emitted from the first speaker unit 30 is
directed to the sound hole 12 via the sound conduit 23. . In other words, the output port 32 is
connected to the passage in the sound conduit 23.
[0019]
The second speaker unit 40 can be a bass speaker unit, and is provided in the second
accommodation portion 26 of the rear sound conducting unit 25 to expand the audio signal
emitted from the second speaker unit 40 as the above. It can be introduced into the sound guide
path 24 via the sound guide hole 253 of the annular peripheral wall 251. The second speaker
unit 40 includes a frame 41, a diaphragm 42, and a lid 43. The diaphragm 42 is disposed
between the frame 41 and the lid 43, and the second speaker unit 40 is through vibration of the
diaphragm 42. Sound waves can be generated, and structures such as pole pieces, magnets, voice
coils and circuit boards can be attached to the frame 41, which is a conventional structure and
thus the detailed description will be omitted here. In addition to this, the lid 43 of the second
speaker unit 40 is further provided to the first speaker unit 30.
[0020]
Thereby, as shown in FIG. 4, if the first speaker unit 30 is a speaker unit for high sound, the
second speaker unit 40 becomes a speaker unit for low frequency. The second speaker unit 40
generates a low frequency sound wave through the vibration of the diaphragm 42 and enters the
sound guide path 24 through the sound guide hole 253 of the rear sound guide 25 so as to be
led to the sound hole 12 (Arrow L1). The high frequency sound waves generated by the first
speaker unit 30 are guided to the sound hole 12 via the sound conduit 23 (arrow L2). Therefore,
since the sound waves of different audio frequencies generated by the first speaker unit 30 and
the second speaker unit 40 do not cause mutual interference even in the process of leading, the
timbre and quality of the sound emitted from the earphone structure 1 are effective Can be
improved.
[0021]
In addition, the structural design of the present invention further extending toward the sound
hole 12 through the sound conduit 23 is that sound waves of different audio frequencies
generated by the first speaker unit 30 and the second speaker unit 40 are generated in the sound
02-05-2019

hole 12. Since it can be coupled at a closer position, the time of mutual interference (which is
likely to interfere with each other because sound waves of different audio frequencies have
different wavelengths and frequencies) is further reduced to significantly reduce the timbre and
quality of the sound emitted from the earphone structure It can improve.
[0022]
FIG. 5 is a cross-sectional view of another embodiment of the earphone structure according to
the present invention.
In the present embodiment, the sound emission port 231 of the sound conduit 23 of the
earphone structure 1a and the sound hole 12 of the housing 10 are substantially in the same
plane. Through this, sound waves of different audio frequencies generated respectively by the
first speaker unit 30 and the second speaker unit 40 can be coupled at the location of the sound
hole 12 to further reduce the time of mutual interference, and the earphone structure 1 It can
improve the tone and quality of the sound emitted from the Simply put, the closer the sound
outlet 231 of the sound conduit 23 is to the sound hole 12 of the housing 10, the more
interference of sound waves of different audio frequencies generated by the first speaker unit 30
and the second speaker unit 40, respectively. Less and less.
[0023]
The technical content of the present invention has been disclosed as described above in the
preferred embodiment, and the scope of protection of the present invention should not be limited
by such an embodiment, and various modifications can be made without departing from the
spirit of the present invention. It is, of course, possible to make changes and modifications within
the scope of the present invention. Therefore, the protection scope of the present invention is
based on what is defined in the claims of the utility model registration attached to the present
specification.
