It would have been obvious to one of the ordinary skills in the art before the effective filing date of the application to use the external mike taught by Nagai as audio input option in the device taught by Waguri. The motivation to do so would have been to communicate with an external device (Nagai et al; Para [0126]). Claim(s) 11, 19 is/are rejected under 35 U.S.C. 103 as being unpatentable over Waguri et al (US 2013/0177191 A1) in view of Osamu et al (JP 2006-173918 A) and further in view of Saeki (US 2018/0183399 A1) and further in view of Hyatt (US 2006/0291671 A1). Regarding claim 11, Waguri et al in view of Osamu et al and further in view of Saeki et al disclose the non-transitory computer- readable medium of claim 9, but do not expressly disclose wherein the instructions, when executed, further configure the microphone to determine the selected digital signal processing mode based on a control signal received from a device external to the microphone. However, in the same field of endeavor, Hyatt disclose an audio method wherein the instructions, when executed, further configure the microphone to determine the selected digital signal processing mode based on a control signal received from a device external to the microphone (Hyatt; Para [0031]). It would have been obvious to one of the ordinary skills in the art before the effective filing date of the application to use the control signal taught by Hyatt as mode control signal option in the device taught by Waguri. The motivation to do so would have been to reduce costs (Hyatt et al; Para [0036]). Regarding claim 19, Waguri et al in view of Osamu et al and further in view of Saeki et al disclose the method of claim 17, but do not expressly disclose further comprising determining the selected digital signal processing mode based on a control signal received from a device external to the microphone. However, in the same field of endeavor, Hyatt disclose an audio method wherein the instructions, when executed, further configure the microphone to determine the selected digital signal processing mode based on a control signal received from a device external to the microphone (Hyatt; Para [0031 ]). It would have been obvious to one of the ordinary skills in the art before the effective filing date of the application to use the control signal taught by Hyatt as mode control signal option in the device taught by Waguri. The motivation to do so would have been to reduce costs (Hyatt et al; Para [0036]). Claim(s) 15, 23 is/are rejected under 35 U.S.C. 103 as being unpatentable over Waguri et al (US 2013/0177191 A1) in view of Osamu et al (JP 2006-173918 A) and further in view of Saeki (US 2018/0183399 A1) and further in view of Sato (US 2010/0106272 A1). Regarding claim 15, Waguri et al in view of Osamu et al and further in view of Saeki et al disclose the non-transitory computer-readable medium of claim 9, but do not expressly disclose wherein each of the plurality of digital signal processing modes comprises a different combination of a microphone position setting and a tone setting. However, in the same field of endeavor, Sato discloses a microphone method wherein each of the plurality of digital signal processing modes comprises a different combination of a microphone position setting and a tone setting (Sato Fig 5; Para [0048]; microphone sensitivity is interpreted as microphone position setting and filtering is interpreted as tone setting).It would have been obvious to one of the ordinary skills in the art before the effective filing date of the application to use the tone setting taught by Sato as processing parameter in the microphone device taught by Waguri. The motivation to do so would have been to facilitate the operation of the device (Sato; Para [0075]). Regarding claim 23, Waguri et al in view of Osamu et al and further in view of Saeki et al disclose the method of claim 17, but do not expressly disclose wherein each of the plurality of digital signal processing modes comprises a different combination of a microphone position setting and a tone setting. However, in the same field of endeavor, Sato discloses a microphone method wherein each of the plurality of digital signal processing modes comprises a different combination of a microphone position setting and a tone setting (Sato Fig 5; Para [0048]; microphone sensitivity is interpreted as microphone position setting and filtering is interpreted as tone setting).It would have been obvious to one of the ordinary skills in the art before the effective filing date of the application to use the tone setting taught by Sato as processing parameter in the microphone device taught by Waguri. The motivation to do so would have been to facilitate the operation of the device (Sato; Para [0075]).
