更詳細而言，各收音單元120包括一主體122、一振膜124及一導音管道126。主體122具有一腔室122a，腔室122a一端具有一第二開口端122b。振膜124連接於主體122的第二開口端122b，振膜124的一表面124a用以貼附於一人體皮膚表面，振膜124的另一表面124b面對主體122所設的腔室122a。導音管道126包含有一導入端126a及相對導入端126a之一導出端126b，導音管道126的導入端126a聲學連結於腔室122a，且導音管道 126的導出端126b與麥克風50聲學連結。收音裝置100更包括一電路板130，電路板130配置於殼體110且耦接於麥克風50。振膜124振動產生的聲波透過導音管道126而傳遞至麥克風50以進行收音。 In more detail, each sound collecting unit 120 includes a main body 122 , a diaphragm 124 and a sound guide pipe 126 . The main body 122 has a chamber 122a, and one end of the chamber 122a has a second open end 122b. The diaphragm 124 is connected to the second open end 122b of the main body 122. One surface 124a of the diaphragm 124 is used to adhere to a human skin surface, and the other surface 124b of the diaphragm 124 faces the chamber 122a of the main body 122. The sound guide tube 126 includes an inlet end 126a and an outlet end 126b opposite to the inlet end 126a. The inlet end 126a of the sound guide tube 126 is acoustically connected to the chamber 122a, and the sound guide tube 126 is acoustically connected to the chamber 122a. The outlet 126b of 126 is acoustically connected to the microphone 50. The sound-collecting device 100 further includes a circuit board 130 , which is disposed on the housing 110 and coupled to the microphone 50 . The sound waves generated by the vibration of the diaphragm 124 are transmitted to the microphone 50 through the sound guide pipe 126 for sound collection.

如上所述，本實施例的收音裝置100在振膜124與麥克風50之間增設了導音管道126。藉此，可依據目標音訊的頻段來決定導音管道126的長度，使目標音訊在導音管道126產生共振而獲得增強，從而提升目標音訊的收音效果，避免雜訊對目標音訊的判讀造成干擾。舉例來說，若目標音訊的頻段為500Hz~1kHz，則導音管道126可據以設計為具有一預定長度，藉以降低導音管道126共振點，且增加500Hz~1kHz頻段的訊號強度。 As mentioned above, the sound collecting device 100 of this embodiment adds a sound guide pipe 126 between the diaphragm 124 and the microphone 50 . In this way, the length of the sound guide pipe 126 can be determined according to the frequency band of the target audio, so that the target audio resonates in the sound guide pipe 126 and is enhanced, thereby improving the sound pickup effect of the target audio and preventing noise from interfering with the interpretation of the target audio. . For example, if the frequency band of the target audio is 500Hz~1kHz, the sound guide pipe 126 can be designed to have a predetermined length, thereby reducing the resonance point of the sound guide pipe 126 and increasing the signal strength in the 500Hz~1kHz frequency band.

在本實施例中，導音管道126設置於主體122外而位於主體122與殼體110的底壁114之間。並且，導音管道126例如是彎折狀，以在有限的配置空間中配置為具有足夠的延伸長度(即，上述預定長度)。此外，本實施例的主體122透過第一開口端110b而凸出於殼體110，以使振膜124位於殼體110外而能夠貼附於目標物(如，人體皮膚表面)。本實施例的各收音單元120更包括一彈性件128，彈性件128連接於殼體110與主體122之間，以藉其彈性力使振膜124能夠緊密地接觸目標物。 In this embodiment, the sound guide pipe 126 is disposed outside the main body 122 and between the main body 122 and the bottom wall 114 of the housing 110 . Furthermore, the sound guide duct 126 is, for example, bent so as to be arranged with a sufficient extension length (ie, the above-mentioned predetermined length) in a limited arrangement space. In addition, the main body 122 of this embodiment protrudes from the housing 110 through the first opening end 110b, so that the diaphragm 124 is located outside the housing 110 and can be attached to a target object (eg, human skin surface). Each sound-collecting unit 120 of this embodiment further includes an elastic member 128. The elastic member 128 is connected between the housing 110 and the main body 122, so that the diaphragm 124 can closely contact the target object through its elastic force.

The mode of action will not be described again here. The difference between the sound collecting unit 220 shown in FIGS. 6 and 7 and the sound collecting unit 120 of the previous embodiment is that some sections of the sound guide pipe 226 of the sound collecting unit 220 extend in an arc shape.
