Boka revaongorori kubva kuBen-Gurion University yeNegev uye Weizmann Institute of Science (Israel) yakagadzira nzira. () kugadzira patsva hurukuro yemukati uye mimhanzi uchishandisa passive vibration ongororo yegirobhu remwenje pendant mwenje. An electro-optical sensor yakaiswa mumugwagwa yakashandiswa seanalyzer uye, uchishandisa telescope, yakanangidzirwa pamwenje unooneka nepahwindo. Kuedza kwakaitwa nemarambi e-12-watt e-LED uye kwakaita kuti zvikwanise kuronga kuterera kubva kure nemamita makumi maviri nemashanu.
Iyo nzira inoshanda kune mwenje wakamiswa. Kudengenyeka kwenzwi kunogadzira misiyano mumhepo, izvo zvinokonzeresa microvibrations yechinhu chakamiswa. Ma microvibrations akadaro anotungamira mukukanganiswa kwechiedza pamakona akasiyana nekuda kwekusimuka kwendege yekupenya, iyo inogona kuwonekwa uchishandisa inonzwisisika electro-optical sensor uye yakaderedzwa kuita ruzha. Teresikopu yakashandiswa kubata kuyerera kwechiedza uye kuitungamira kune sensor. Chiratidzo chakagamuchirwa kubva kune sensor (Thorlabs PDA100A2 yakavakirwa pafotodiode) yakashandurwa kuita fomu yedhijitari uchishandisa 16-bit analog-to-digital converter ADC NI-9223.
Kuparadzaniswa kwemashoko ane chokuita nezwi kubva kune general optical signal yakaitwa mumatanho akawanda, kusanganisira , normalization, kuderedza ruzha uye amplitude kururamisa nekuwanda. A MATLAB script akagadzirirwa kugadzirisa chiratidzo. Hunhu hwekudzoreredza ruzha kana uchitora maparamendi kubva kure nemamita makumi maviri neshanu wakave wakakwana pakuzivikanwa kwekutaura kuburikidza neGoogle Cloud Speech API uye nekuona kuumbwa kwemimhanzi kuburikidza neShazam uye SoundHound masevhisi.
Mukuedza, inzwi rakadzokororwa muimba pahuwandu hwehuwandu hwevatauri varipo, i.e. ruzha rwacho rwakanga rwakanyanya kudarika kutaura kwakajairika. Mwenje we LED haunawo kusarudzwa nemukana, asi sekupa chiratidzo chepamusoro-kune-ruzha reshiyo (6.3 times yakakwirira kupfuura mwenje weincandescent uye 70 nguva dzakakwirira kupfuura mwenje wefluorescent). Vatsvakurudzi vakatsanangura kuti kurwisa uye kunzwisiswa kunogona kuwedzerwa nekushandisa teresikopu yakakura, sensor yepamusoro-soro, uye 24- kana 32-bit analog-to-digital converter (ADC); kuedza kwakaitwa uchishandisa teresikopu inobatsira. sensor yakachipa, uye 16-bit ADC.
Kusiyana nenzira yakambotaurwa "", iyo inobata uye inoongorora zvinhu zvinozunguzika mukamuri, senge girazi remvura kana chip package, Lamphone inoita kuti zvikwanise kuronga kuteerera munguva chaiyo, nepo maikorofoni inooneka yekuvakazve mashoma mashoma ekutaura inoda kuverenga kwakadzama kunotora. maawa . Kusiyana nenzira dzinobva pakushandiswa kana semaikorofoni, Lamphone inobvumira kurwiswa kuti kuitwe kure, pasina chikonzero chekumhanyisa malware pamidziyo iri munzvimbo. Kusiyana kurwisa kushandisa , Lamphone haidi kuvhenekerwa kwechinhu chinozunguzika uye inogona kugadzirwa mune passive mode.
