Description of the Invention: [Technical Field] The present invention relates to a sound processing apparatus, and more particularly to an audio apparatus having a convenient user to practice singing. [Prior Art] At present, general household audio equipment has only functions such as volume adjustment, low-pitched enhancement, and high-pitched enhancement. However, when the pitch of the music is higher or lower than the highest and lowest pitch that the singer can sing, it will not only affect the harmony of the accompaniment sound and the singing voice of the singer, but also the confidence of the singer and the influence. Singing entertainment. In addition, the audio equipment cannot eliminate the original singing, and the user is susceptible to the original singing when the singing is performed, and the best singing effect cannot be achieved. SUMMARY OF THE INVENTION In view of the above, an acoustic output device is provided to solve the problem that the prior art audio device cannot adjust the tone of the music. The provided sound output device also solves the problem that the prior art audio device Φ cannot eliminate the original sing. The sound processing device is disposed between a sound source and a speaker, and processes the audio signal output by the sound source and outputs the audio signal to the speaker, comprising: a practice selector for selecting a practice mode, The sound processing device outputs a tone-adjusted audio signal in a practice mode; and a tone adjustment module for adjusting a tone of the audio signal output by the sound source in the practice mode. The sound processing device further includes an original utterance elimination module for attenuating the vocal frequency band in the audio output audio signal in the practice mode. 6 1304570
因此，相較現有技術，上述聲音處理裝置不僅方便使 用者練唱，還增加了使用者練唱時的娛樂性。 【實施方式】 請參閱圖1所示，是本發明聲音處理裝置一實施方式 的架構圖。在本實施方式中，所述聲音處理裝置20是一音 響裝置20。所述音響裝置2〇上設置有一模式選擇開關 25〇。所述模式選擇開關250供使用者發送一模式切換信號 至 緣口曰1擇器230，所述練唱選擇器230 一端接一功率 放大器240,另一端根據模式切換信號的控制直接接一音 '、或、、二由曰凋調節模組220與一原唱消除模組21〇後 再接音源10。練唱選擇器230直接接音源1〇時，音響裝 置20處於—正常模式下，練唱選擇器23〇將音源ίο ϋ ^音頻信號輪出至功率放大器施，由功率放大器240放 立ίί出至—揚聲器3〇 ’揚聲器30將音頻信號轉換成聲 在正常模式下’當音源1〇輸出為包含歌手 曰市才使用者聽到揚聲器3〇發出的聲音亦為包含 歌手原唱的音樂。 當練唱選擇哭2川 伊力 、 ™ 、、工由曰调調節模組220與原唱消除 :、:?二接音源10時’音響裝置20處於-練唱模式下， Γ，、· 的音頻信號經原唱消除模組挪衰減人聲頻 模組咖3奏音進入音調調節模組220。所述音調調節 功率放大Γ即伴奏音音調後經由練唱選擇器230後輸出至 器％輸出。因此240將伴奏音放大，由揚聲 練曰模式下，即使音源10的輸出包 7Therefore, compared with the prior art, the above-mentioned sound processing device not only facilitates the user to practice singing, but also increases the entertainment of the user when practicing singing. [Embodiment] Referring to Figure 1, there is shown a block diagram of an embodiment of a sound processing device according to the present invention. In the present embodiment, the sound processing device 20 is an audio device 20. A mode selection switch 25A is disposed on the acoustic device 2A. The mode selection switch 250 is configured for the user to send a mode switching signal to the edge port selector 230. The one end of the practice selector 230 is connected to a power amplifier 240, and the other end is directly connected to a sound according to the control of the mode switching signal. The sound source 10 is connected to the original sound elimination module 21 and the sound source 10 after the adjustment module 220 is removed. When the practice selector 230 is directly connected to the audio source 1 , the audio device 20 is in the normal mode, and the practice selector 23 turns the audio signal ί ^ 音频 the audio signal out to the power amplifier, and is discharged by the power amplifier 240 to the power amplifier 240. - Speaker 3 〇 'Speaker 30 converts the audio signal into sound in normal mode' When the sound source 1 〇 output is included in the singer, the user hears the sound of the speaker 3 亦 is also the music containing the singer's original singer. When practicing singing, choose to cry 2 Sichuan Yili, TM, and work by the adjustment module 220 and the original singer elimination:,:? When the two sources 10 are connected, the 'audio device 20 is in the - singing mode, Γ,, · The audio signal enters the tone adjustment module 220 via the original utterance elimination module to attenuate the human audio module 3 sound. The pitch adjustment power amplification, that is, the accompaniment tone, is output to the device % output via the practice selector 230. Therefore, 240 will amplify the accompaniment sound, and the output of the sound source 10 is even under the sound mode.
