Portable karaoke speaker structure

This creative department belongs to a technical field of sing-song, specifically a multi-channel portable karaoke speaker structure, which can avoid the interference of back-sounding and improve the quality of sound output.

According to the development of society, people's lives and work are becoming more and more tense, and psychological pressures are also increasing. Many problems and diseases are caused by excessive psychological depression, such as: depression, bipolar disorder, headache. The chest is depressed, etc. Therefore, how to properly relieve the pressure has been regarded as an important issue. At present, common methods of singing include singing, listening to music, dancing, swimming or climbing, etc. Among them, singing and listening to music are the most popular, which allows people to immerse themselves in notes and shouts of different rhythms. Moderate relaxation, to achieve the effect and role of regulating body and mind.

At present, although the technology and application of karaoke are very extensive and mature, the current singing is mainly to professional places such as KTV or karaoke shops, and the limitations of all the space and equipment in these fields cannot satisfy the desire of people to sing at any time. Due to the lack of portable simplified devices, the personal use of portable karaoke products is less, affecting the convenience of people singing anywhere, anytime; although there is currently a Bluetooth speaker with a microphone on the market, so that people can It is used as its own karaoke method, but because the speaker will As the sound is generated and the vibration frequency is the same, when the microphone and the speaker are integrated or close to each other, the microphone is prone to a strong self-feedback effect, causing the speaker to emit a continuously and continuously enhanced feedback sound of the same frequency. That is to say, the so-called whistling, which destroys the overall sound quality, even causes the Bluetooth speaker with the microphone to be used normally. Moreover, the existing Bluetooth speaker with a microphone usually has only one speaker, which cannot produce multi-channel stereo sound effects such as low and heavy sounds, and cannot effectively improve the sound quality, and the user may have poor sound quality after using for a period of time. Losing interest, so there is indeed a need to discuss the existing ones, and there is a need for further improvement.

In view of this, the creator is in-depth discussion on the problems faced by the aforementioned Bluetooth microphones with microphones, and actively pursues solutions through years of experience in R&D and manufacturing of related industries, and has been continuously researching and trialing. Finally, we successfully developed a portable karaoke speaker structure, which can effectively overcome the troubles and inconvenience caused by the existing mono only.

Therefore, the purpose of the present invention is to provide a portable karaoke speaker structure, so that it can have multi-channel stereo sound, which can effectively improve the sound quality and satisfy the user's sound quality requirements for different songs.

Moreover, another main purpose of the present invention is to provide a portable karaoke speaker structure that can vocalize around without disturbing the whistling sound, further enhancing the sound-absorbing effect.

Accordingly, the present invention mainly achieves the aforementioned purposes and effects through the following technical means: it includes: a speaker body having a shell with open sides formed on both sides The body is provided with two cavities corresponding to the openings on both sides, and the cavities are respectively provided with a first horn and a second horn corresponding to the openings on both sides of the housing, and the housing is corresponding to the first A speaker net group is arranged on both sides of the two speakers, and a circuit board with a Bluetooth transmission and a sound processing function is disposed on the inner edge of the front side of the casing; a wireless microphone is disposed on the top surface of the cavity of the speaker body. And passing through the connector of the housing, and the connector is provided with a pickup that can be connected to the signal of the circuit board.

In this way, through the above-mentioned technical means, the built-in karaoke speaker structure of the present invention can utilize the first and second speakers of the speaker body to receive the sound source signal of the external multimedia device such as a mobile phone through the Bluetooth transmission function of the circuit board, and play independently. Music, and can also use the wireless microphone pickup to receive the singing voice, and after being converted by the circuit board, the first and second speaker outputs of the speaker body are amplified, and the karaoke with multi-channel stereo sound is realized, and the speaker is simultaneously The body can avoid the back-sounding interference of the speaker body and greatly improve the sound quality, so it can greatly increase the added value of the product and improve the economic efficiency and competitiveness of the product.

In order to enable the review board to further understand the composition, characteristics and other purposes of the creation, the following are some of the preferred embodiments of the creation, and the detailed description of the creation is as follows, and the person familiar with the technical field can The specification is implemented.
