Description
本發明係關於一種耳機麥克風混音裝置,特別是關於一種使用安卓(Android)系統或iOS系統之手機、平板等手持式裝置進行直播時,輸出至耳機的軟體音效可直接混音到麥克風輸入端的混音裝置。 The present invention relates to a headset microphone mixing device, and particularly to a mobile phone, tablet and other handheld devices using Android system or iOS system for live broadcast, the software sound effect output to the headset can be directly mixed to the microphone input Mixing device.
按,由於手持式裝置的隱私權限的問題,如安卓系統的手機,有些國家的法律不允許通話側錄,因此Google將安卓系統全部都封鎖權限使得安卓手機不支援系統軟體內部的收音,僅支援使用外接式麥克風或手機上的麥克風收音。 Press, due to the privacy permissions of handheld devices, such as Android phones, the laws of some countries do not allow call recording. Therefore, Google blocks all Android systems so that Android phones do not support the internal radio of the system software, only support Use an external microphone or the microphone on your phone to receive audio.
現今正流行網路直播,直播主大都使用手機、平板等手持式裝置進行直播,如手機遊戲直播,但安卓系統的手機卻無法讓收看觀眾一起聽到手機遊戲軟體所發出的音效,必需先利用外接揚聲器播放出來後,再由外接的麥克風收音才能讓觀眾聽到手機遊戲的音效。 Nowadays, webcasting is popular. Most of the live broadcasters use mobile phones, tablets and other handheld devices for live broadcasts, such as mobile game live broadcasts. However, Android phones cannot let the audience hear the sound effects of mobile game software. After the speaker is played, the external microphone can be used to pick up the sound to allow the audience to hear the sound of the mobile game.
然而此種方式,將遊戲軟體所產生的立體臨場音效經由空氣傳輸到麥克風收音時,即喪失了立體臨場感,收看觀眾無法感受到直播主所聽到的立體臨場音效,而且相當容易受到周遭環境聲音的干擾,若在網咖或網吧時,外接揚聲器所發出的聲音也會干擾到周圍的其他人。 However, in this way, when the stereoscopic presence sound generated by the game software is transmitted to the microphone through the air, the stereoscopic presence is lost, and the viewer cannot feel the stereoscopic presence sound effect heard by the live broadcaster, and it is quite vulnerable to surrounding environmental sounds. If you are in an Internet cafe or an Internet cafe, the sound from the external speaker will also interfere with other people around you.
亦有人使用市面上昂貴的混音器連接多組的輸入音源進行混音,但僅可使用在電腦遊戲的直播,仍無法使用在手機遊戲的直播,且 會有諸多問題產生,例如安卓手機或平板的耳機麥克風是使用同一接孔,因此必需使用一分接線,將輸出音源與輸入音源分離連接至混音器,又要外接耳機及麥克風,線路相當繁雜。 Some people use expensive mixers on the market to connect multiple sets of input sources for mixing, but they can only be used in the live broadcast of computer games, and still cannot be used in the live broadcast of mobile games. There will be many problems. For example, the earphones and microphones of Android phones or tablets use the same jack, so it is necessary to use a split cable to separate the output sound source and the input sound source to the mixer, and external earphones and microphones, the wiring is quite complicated .
又例如習知的混音器無法單純地只接收手機或平板的遊戲軟體所產生的音效,因為當使用者只插耳機時,手機或平板會判斷只接耳機未接麥克風,而自動地開啟手機上的麥克風收音,所以不論使用者是否使用麥克風都會造成環境中的噪音被強制接收。因此習知市售的混音器仍有諸多無法克服的缺失,尚有改善的空間。 For example, the conventional mixer cannot simply receive the sound effects generated by the game software of the mobile phone or tablet, because when the user only plugs in the headset, the mobile phone or tablet will judge that only the headset is connected but the microphone is not connected, and automatically turn on the phone The microphone on the microphone receives sound, so no matter whether the user uses the microphone or not, the noise in the environment will be forced to receive. Therefore, the conventional mixers on the market still have many insurmountable deficiencies, and there is still room for improvement.
本發明之目的在於提供一種手持裝置之耳機麥克風混音裝置,可將不支援內部收音之手持裝置的內部軟體音效,無干擾地回授給手持裝置之目的,並可讓使用者開啟或關閉麥克風的收音,而不會讓手持裝置自動開啟內建麥克風的功效,且本發明電路簡單,無需外接電源。 The purpose of the present invention is to provide a headset microphone mixing device for a handheld device that can feedback the internal software sound effects of a handheld device that does not support internal radio to the handheld device without interference, and allows the user to turn on or off the microphone The sound is received without allowing the handheld device to automatically turn on the function of the built-in microphone, and the circuit of the invention is simple and does not require an external power supply.

請再一併參閱第1圖及第3圖所示,本發明為了讓使用者可切換是否使用麥克風25收音,而在本發明之耳機麥克風混音裝置20中設計一切換開關28及一虛擬麥克風29,主要是讓使用者可以關閉或開啟麥克風25的收音,可用在環境吵鬧的場合,或者使用者只想單純地將手持裝置10的軟體音效無干擾地回授給手持裝置10時,即可以關閉麥克風25的收音。
Please refer to Figures 1 and 3 together. In order to allow the user to switch whether to use the
然而若只是將麥克風25的連接切斷時,手持裝置10的內部系統會認為只有接耳機27而未接麥克風25,因而強制將手持裝置10的內建麥克風12開啟,進行收音。因此本發明又設計了一只虛擬麥克風29,讓手持裝置10誤認為有接麥克風25而不會開啟內建麥克風12,較佳地如第3圖所示,本發明實施例中之虛擬麥克風為一電阻器,在其它實施例中,該虛擬麥克風可以為一個麥克風晶片。
However, if only the connection of the
而該切換開關28則連接於該外接麥克風輸入端22與該混音比例調節電路23之間,以及連接於該虛擬麥克風29與該混音比例調節電路23之間,用以切換該混音比例調節電路23是與該外接麥克風輸入端22連接,或者與該虛擬麥克風29連接。
The
當該切換開關28切換為連接該外接麥克風輸入端22與該混音比例調節電路23時,可將該混合音源傳送至該手持裝置10的麥克風連接端15,使該混合音源回授給該手持裝置10收音。而當該切換開關28切為連接該虛擬麥克風29與該混音比例調節電路23時,可單
純地僅將該立體音源傳送至該手持裝置10的麥克風連接端15,使原本傳送給耳機連接端14的該立體音源,無干擾地回授給該手持裝置10收音。
