The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA .
The specification has not been checked to the extent necessary to determine the presence of all possible minor errors. Applicant’s cooperation is requested in correcting any errors of which applicant may become aware in the specification.
Applicant’s election without traverse of Species I (Figures 6-19) in the reply filed on April 20, 2026 is acknowledged. The applicant identifies claims 1, 3-7, 10-14, and 16-22 as being applied to the elected species.
The examiner, however, respectfully disagrees with the applicant’s assertion that claims 6, 7, and 19 are readable on the elected Species I (Figures 6-19). Claims 6, 7, and 19 recite a “first end face” and/or a “second end face”, which are only readable on the non-elected Species II (Figures 20-24). See para. 00175 of the specification, for example, which disclose the claimed “first end face” as element 3234 and the claimed “second end face” as element 3235 in the non-elected Species II (e.g., Figure 22).
Accordingly, only claims 1, 3-5, 10-14, 16-18, and 20-22 are considered readable on the elected Species I (Figures 6-19). Claims 6-9 and 19 are withdrawn from further consideration as being drawn to a nonelected species.
Claim 17 is objected to under 37 CFR 1.75 as being a substantial duplicate of claim 4.
Claim 20 is objected to under 37 CFR 1.75 as being a substantial duplicate of claim 10.

The following is a quotation of 35 U.S.C. 103 which forms the basis for all obviousness rejections set forth in this Office action:
A patent for a claimed invention may not be obtained, notwithstanding that the claimed invention is not identically disclosed as set forth in section 102, if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains. Patentability shall not be negated by the manner in which the invention was made.
This application currently names joint inventors. In considering patentability of the claims the examiner presumes that the subject matter of the various claims was commonly owned as of the effective filing date of the claimed invention(s) absent any evidence to the contrary. Applicant is advised of the obligation under 37 CFR 1.56 to point out the inventor and effective filing dates of each claim that was not commonly owned as of the effective filing date of the later invention in order for the examiner to consider the applicability of 35 U.S.C. 102(b)(2)(C) for any potential 35 U.S.C. 102(a)(2) prior art against the later invention.
Claims 10, 20, and 21 are rejected under 35 U.S.C. 103 as being unpatentable over Cho et al. (US 10,743,097), as applied to claim 1 and claim 3 above, in further view of Saiki et al. (US 2011/0044489).
Cho discloses the invention as claimed, but fails to specifically teach that the magnetic circuit component 110, 110’ further comprises a magnetic fluid, wherein the magnetic fluid fills the magnetic gap 400 and wraps at least a part of the voice coil 200 (see fig. 1, for example). Saiki discloses an electronic speaker device (see figs. 1(b) and 2(b), for examples) including a magnetic circuit component including a magnetic gap, a diaphragm, a voice coil inside the magnetic gap, and a magnetic fluid 17/27, wherein the magnetic fluid 17/27 fills the magnetic gap and wraps at least a part of the voice coil, in the same field of endeavor, for the purpose of preventing burnout of the voice coil (see para. 0016).
It would have been obvious to one having ordinary skill in the art before the effective filing date of the invention to modify Cho, in view of Saiki, such that the magnetic circuit component 110, 110’ further comprises a magnetic fluid, wherein the magnetic fluid fills the magnetic gap 400 and wraps at least a part of the voice coil 200. A practitioner in the art would have been motivated to do this for the purpose of preventing burnout of the voice coil 12 during operation of the electronic device.
Claims 13 is rejected under 35 U.S.C. 103 as being unpatentable over Cho et al. (US 10,743,097), as applied to claim 1 above, in further view of Ueda et al. (US 2007/0274543).
Cho discloses the invention as claimed, including that the first diaphragm 140 or the second diaphragm 140’ includes a surface which is close to the voice coil 200 (see fig. 1, for example), but fails to specifically teach that the vibration component further includes a connection line on the surface and that the connection line is electrically coupled to the voice coil 200. Ueda discloses an electronic speaker device including a diaphragm bonded to a voice coil, and a magnetic circuit, wherein the voice coil is inserted into a magnetic gap of the magnetic circuit, wherein “lead wires of this voice coil are adhesively attached to the back face of the diaphragm, and the ends of the lead wires are electrically connected to a terminal plate (power supply terminal) provided on the outside of the diaphragm”, in the same field of endeavor, for the purpose of electrically connecting the voice coil to an external signal source to produce sound by the diaphragm (see para. 0002).
It would have been obvious to one having ordinary skill in the art before the effective filing date of the invention to modify Cho, in view of Ueda, such that the vibration component further includes a connection line on a surface of the first diaphragm 140 or the second diaphragm 140’ and that the connection line is electrically coupled to the voice coil 200. A practitioner in the art would have been motivated to do this for the purpose of electrically connecting the voice coil to an external signal source to produce sound by the first diaphragm or the second diaphragm.
Claims 16 is rejected under 35 U.S.C. 103 as being unpatentable over Cho et al. (US 10,743,097), as applied to claim 1 above, in further view of Chiba et al. (US 2007/0081692).
Cho discloses the invention as claimed, including that the casing 500 (see fig. 9, for example), comprises a mounting space, wherein the speaker 100 is mounted in the mounting space and separates the mounting space into a first cavity (e.g., the first cavity having arrow S1 therein) and a second cavity (e.g., the second cavity having arrow S2 therein), but fails to specifically teach that a sound outlet is configured to interact with the mounting space, wherein the first cavity is configured to interact with the sound outlet, and that the housing of the speaker 100 further includes an opening hole on a side wall of the housing, wherein the opening hole is configured to interact with the inner cavity and the second cavity. Chiba discloses an electronic speaker device (see figures 3-5, for example) including a housing comprising an inner cavity S1, a magnetic circuit component in the inner cavity and including a magnetic gap, a diaphragm, and a voice coil inside the magnetic gap, wherein the housing includes an opening hole 4a on a side wall of the housing, wherein the opening hole 4a is configured to interact with the inner cavity S1 and an external space, in the same field of endeavor, for the purpose of preventing the pressure in the speaker device from becoming too high and further to allow the diaphragm to move smoothly (see para. 0056-0058).
It would have been obvious to one having ordinary skill in the art before the effective filing date of the invention to modify Cho, in view of Chiba, such that the housing of the speaker 100 further includes an opening hole on a side wall of the housing, wherein the opening hole is configured to interact with the inner cavity and the second cavity. A practitioner in the art would have been motivated to do this for the purpose of preventing the pressure in the electronic speaker device from becoming too high and further to allow the diaphragm to move smoothly. Furthermore, although the covers of the casing 500 in fig. 9 do not include an outlet hole as claimed, it would have been obvious to include an outlet hole in the covers of the casing 500 to facilitate sound transmission out of the casing 500 (see fig. 3 of Chiba, for example, which teaches sound outlet holes 7a for such a purpose).
Claims 10, 20, and 21 are rejected under 35 U.S.C. 103 as being unpatentable over Wang et al. (US 2021/0274289), as applied to claim 1 and claim 3 above, in further view of Saiki et al. (US 2011/0044489).
Wang discloses the invention as claimed, but fails to specifically teach that the magnetic circuit component 32, 33 further comprises a magnetic fluid, wherein the magnetic fluid fills the magnetic gap 36 and wraps at least a part of the voice coil 12 (see fig. 7, for example). Saiki discloses an electronic speaker device (see figs. 1(b) and 2(b), for examples) including a magnetic circuit component including a magnetic gap, a diaphragm, a voice coil inside the magnetic gap, and a magnetic fluid 17/27, wherein the magnetic fluid 17/27 fills the magnetic gap and wraps at least a part of the voice coil, in the same field of endeavor, for the purpose of preventing burnout of the voice coil (see para. 0016).

A practitioner in the art would have been motivated to do this for the purpose of preventing burnout of the voice coil 12 during operation of the electronic device.
Claims 13 is rejected under 35 U.S.C. 103 as being unpatentable over Wang et al. (US 2021/0274289), as applied to claim 1 above, in further view of Ueda et al. (US 2007/0274543).
Wang discloses the invention as claimed, including that the first diaphragm 11 or the second diaphragm 21a includes a surface which is close to the voice coil 12 (see fig. 4, for example), but fails to specifically teach that the vibration component further includes a connection line on the surface and that the connection line is electrically coupled to the voice coil 12. Ueda discloses an electronic speaker device including a diaphragm bonded to a voice coil, and a magnetic circuit, wherein the voice coil is inserted into a magnetic gap of the magnetic circuit, wherein “lead wires of this voice coil are adhesively attached to the back face of the diaphragm, and the ends of the lead wires are electrically connected to a terminal plate (power supply terminal) provided on the outside of the diaphragm”, in the same field of endeavor, for the purpose of electrically connecting the voice coil to an external signal source to produce sound by the diaphragm (see para. 0002).
