Description

Audio mixing device

The present invention relates to a signal synthesizing device, and more particularly to an audio mixing device.

Handheld electronic products, especially mobile phones, have made great progress with the development of technology. Not only can the performance be comparable to that of a desktop computer, but it can also be connected to the digital message space through the Internet, and the sound and light information can be transmitted through the media interface. As a result, devices and applications that match these phones have sprung up. The karaoke as a traditional entertainment is also catching up with this trend. For example, a mobile phone with a sound mixing function disclosed in the Japanese Patent No. 101034545 directly receives a user's singing voice directly on the mobile phone, and interacts with the mobile phone. The background audio is synthesized to output a mixed audio associated with the composite result, thereby achieving personalized karaoke. However, 囿 is limited to the built-in speaker power of the mobile phone, so that the sound effect is greatly reduced, greatly reducing the pleasure of the user singing. Therefore, as in the case of the Republic of China new patent No. M359867, a sound reinforcement seat includes a sound amplification circuit connectable to a microphone. The sound amplification circuit inputs the vocal audio by the microphone, and amplifies and outputs the power of the vocal audio, and simultaneously plays the background audio with the mobile phone, so that the user Feel like the vocal effect of singing in KTV.

However, the loudspeaker has the following disadvantages:

1. The sound amplification circuit only separately amplifies the power of the vocal audio, and does not simultaneously power-amplify the background audio played by the mobile phone, thereby not only discarding the use of the sound reinforcement stand alone for mobile phone amplification, but also being mixed The sound quality is uneven.

Second, the sound reinforcement seat can only provide a single user to sing. For a double chorus song, you can only sing with the mobile phone alone, or exchange the microphone in turn to achieve a chorus. It is not only convenient to use, but also loses accompaniment. The entertainment effect of singing.

Therefore, the object of the present invention is to provide an audio mixing device with a complete sound reinforcement function and can be sung by many people.

Thus, the novel audio mixing device is provided for a media device and at least one radio device. The media device outputs a pitch signal; the radio device outputs a consonant signal. The audio mixing device comprises a base, an audio receiving unit, a mixing unit, a sound amplifying unit, and a power module.

The base is available for placement by the media device.

The audio receiving unit is disposed on the base, and includes an audio plug for inserting the media device, and a plurality of audio jacks for inserting the plurality of radios.

The mixing unit is electrically connected to the audio receiving unit, and receives the pitch signal, and is combined with the consonant signals to output a mixing signal related to the composite result.

The sound amplification unit is mounted on the base and configured to receive the sound mixing signal and output a sound related to the sound mixing signal.

The power module is assembled on the base and configured to provide energy for the sound amplification unit to output the sound.

The effect of the novel is that the pitch signal and the consonant signals are synthesized by the mixing unit, so that not only can the plurality of people sing at the same time, but also the sound is played through the sounding unit, so that the sound quality is better.
