Description

手持裝置之耳機麥克風混音裝置 Headphone microphone mixing device of handheld device

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.

其中該音源輸出端24除了連接該混音比例調節電路23外，更透過該手持裝置10的耳機/麥克風插接孔13連接至該麥克風連接端15，用以將該混音比例調節電路23所產生之該混合音源傳送至該麥克風連接端15，使不支援內部收音的該手持裝置10能將內部軟體音效之立體音源，混合麥克風25收音之該混合音源，回授給該手持裝置10。如使用者進行手機遊戲直播時，可將手機遊戲軟體的音效以及使用者說話的聲音混音後上傳至直播網站。 In addition to connecting the sound source output terminal 24 to the sound mixing ratio adjustment circuit 23, it is also connected to the microphone connection terminal 15 through the earphone/microphone jack 13 of the handheld device 10 for the sound mixing ratio adjustment circuit 23. The generated mixed audio source is sent to the microphone connection terminal 15 so that the handheld device 10 that does not support internal audio can feed back the stereo audio source of the internal software sound effect and the mixed audio source of the mixed microphone 25 to the handheld device 10. For example, when a user is conducting a live broadcast of a mobile game, the sound effects of the mobile game software and the user's speech can be mixed and uploaded to the live broadcast website.

最佳地，本發明耳機麥克風混音裝置20中更包括一外接耳機輸出端26，較佳地同樣可為一3.5MM插孔，可外接一耳機27或一揚聲器。該外接耳機輸出端26連接至該音源輸入端21，用將手持裝置10傳送至該耳機連接端14的立體音源，無耗損地傳送至該耳機27或該揚聲器播放。 Preferably, the earphone-microphone mixing device 20 of the present invention further includes an external earphone output terminal 26, preferably a 3.5MM jack, which can be connected with a earphone 27 or a speaker. The external earphone output terminal 26 is connected to the sound source input terminal 21, and the stereo sound source transmitted from the handheld device 10 to the earphone connection terminal 14 is transmitted to the earphone 27 or the speaker for playback without loss.

較佳地，該外接耳機輸出端26則可為一3.5MM獨立插座，而該耳機27或該揚聲器則可為一3.5MM獨立插頭，只單獨連接耳機27或揚聲器；或者該外接耳機輸出端26可與該外接麥克風輸入端22為同一3.5MM音源插座的不同連接點，而外接式耳機27與麥克風25則為同一3.5MM插頭，可同時連接外接式的耳機27與麥克風25。 Preferably, the external headphone output 26 can be a 3.5MM independent socket, and the headphone 27 or the speaker can be a 3.5MM independent plug, and only the headphone 27 or speaker is connected separately; or the external headphone output 26 Can be the same as the external microphone input 22 A 3.5MM audio source socket has different connection points, and the external earphone 27 and the microphone 25 are the same 3.5MM plug, which can be connected to the external earphone 27 and the microphone 25 at the same time.

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 microphone 25 to receive the sound, a switch 28 and a virtual microphone are designed in the headset microphone mixing device 20 of the present invention. 29. It is mainly for the user to turn off or turn on the microphone 25, which can be used in a noisy environment, or when the user just wants to simply feedback the software sound effects of the handheld device 10 to the handheld device 10 without interference. Turn off the microphone 25.

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 microphone 25 is cut off, the internal system of the handheld device 10 will consider that only the earphone 27 is connected and the microphone 25 is not connected, and therefore the built-in microphone 12 of the handheld device 10 is forced to be turned on for radio reception. Therefore, the present invention designs a virtual microphone 29 to make the handheld device 10 mistakenly believe that the microphone 25 is connected without turning on the built-in microphone 12. Preferably, as shown in Figure 3, the virtual microphone in the embodiment of the present invention is A resistor. In other embodiments, the virtual microphone may be a microphone chip.

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 switch 28 is connected between the external microphone input 22 and the mixing ratio adjusting circuit 23, and between the virtual microphone 29 and the mixing ratio adjusting circuit 23, for switching the mixing ratio The adjustment circuit 23 is connected to the external microphone input terminal 22 or to the virtual microphone 29.

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。 When the switch 28 is switched to connect the external microphone input 22 and the mixing ratio adjustment circuit 23, the mixed audio source can be transmitted to the microphone connection terminal 15 of the handheld device 10, so that the mixed audio source can be fed back to the handheld The device 10 receives audio. And when the switch 28 is switched to connect the virtual microphone 29 and the mixing ratio adjustment circuit 23, you can simply Only the stereo sound source is transmitted to the microphone connection terminal 15 of the handheld device 10, so that the stereo sound source originally transmitted to the earphone connection terminal 14 is fed back to the handheld device 10 for reception without interference.

綜上所述，本發明已藉由上述相關實施例的描述，使本發明之手持裝置之耳機麥克風混音裝置可達到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的功效，且本發明電路簡單，無需外接電源，然而上述實施例僅為實施本發明之範例，並未限制本發明之範圍。相反地，包含於申請專利範圍之精神及範圍之修改及均等設置，均包含於本發明之範圍內。 In summary, the present invention has been described in the above-mentioned related embodiments so that the headset microphone mixing device of the handheld device of the present invention can achieve the feedback of the internal software sound effects of the handheld device that does not support internal radio to the handheld without interference. The effect of the device, and the circuit of the present invention is simple, and no external power supply is needed. However, the above-mentioned embodiments are only examples for implementing the present invention and do not limit the scope of the present invention. On the contrary, all modifications and equal arrangements included in the spirit and scope of the patent application are included in the scope of the present invention.
