Integrated mobile K-song broadcasting system convenient to carry
Technical Field
The utility model belongs to the technical field of electroacoustic public address equipment, especially, relate to a K song broadcasting system is removed to portable's integrated form.
Background
At present, a small integrated karaoke device with a loudspeaker and a microphone integrated into a whole is available in the market, and the integrated karaoke device is small in size, easy to carry and convenient to use, and can be recognized by consumers and the market. However, in the using process, the loudspeaker and the pickup mark (the microphone head) in the integrated design are integrated, so that the sound expansion sound source is always near the head of the singer, the transmission of sound waves is limited, the expanded sound cannot be heard by more people, and only the singer can hear the sound by himself; secondly, the mark is too close to the loudspeaker, so that howling is easily generated; thirdly, the sound producing loudspeaker is arranged on the microphone, even if a plurality of loudspeakers on the microphone produce sound simultaneously, the sound producing loudspeaker is a formed single-point sound source, and the sound producing loudspeaker cannot form a vertical sound effect. The sound field is narrow, and has numerous problems in the aspects of tone quality, sound field range, audio dynamics, flexibility of use and free combination expansibility, so that only singers can entertain and play themselves, and the experience of professional entertainment singing cannot be achieved.
Therefore, the design of the small split type handheld K Songbao which can be split and freely combined, has various playing methods and non-interfering pronunciation and can realize wireless interconnection of a plurality of different loudspeakers is the key for solving the problems.

Detailed Description
In order to make those skilled in the art better understand the technical solution of the present invention, the following detailed description is provided with reference to the accompanying drawings.
As shown in fig. 1-8, K song broadcasting system is removed to portable's integrated form, including microphone 1, the small-size stereo set 11 of several that disposes with microphone 1, the upper portion is provided with miaow core 2 in the casing of microphone 1, and lower part sets up controlling means in the casing of microphone 1, be provided with several installing key 3 on the casing outer wall of the well lower part of microphone 1, each be provided with on the small-size stereo set 11 with the suitable arc installation department 12 of microphone 1 casing, correspond each installing key 3 on the arc installation department 12 and be provided with installation slot 13, each small-size stereo set 11 through installation slot 13 cooperation installing key 3 detachably set up on the casing outer wall of microphone 1.
Control device include control circuit board 4 and with 4 signal connection's of control circuit board bluetooth receiving module 5, DSP audio frequency processing module 6, U section radio frequency emission module 7, battery 8, bluetooth receiving module 5, DSP audio frequency processing module 6 set up in the casing middle part of microphone 1, U section radio frequency emission module 7, battery 8 set up in the casing lower part of microphone 1, be provided with display screen and function key on the control circuit board 4, and display screen and function key then set up on the casing. The working principle is that after the microphone core 2 picks up the voice, the voice is transmitted to the DSP audio processing module to carry out the correction of the balanced volume and the tone and the processing of the mixing effect; the audio frequency transmitted by the mobile phone or the computer Bluetooth and received by the Bluetooth receiving module 5, such as accompaniment music, and the like, is also sent to the DSP audio processing module 6 for correction and equalization, and the user calls the preset and self-defined effects by using the operation keys on the microphone 1 and can modify the preset and self-defined effects; and finally transmitted to an external receiving device, namely the small-sized sound box 11, by radio frequency. Through with DSP audio frequency processing module 6 built-in on microphone 1, make things convenient for the better work of small-size stereo set 11, and use on user's hand, convenient effect operation and the control anytime and anywhere, carry to use and promote convenience and user experience sense.
Mounting key 3 be ring structure, 3 axial equidistance of mounting key set up on the casing outer wall of microphone 1 middle and lower part, and outside protrusion, installation card groove 13 is the ring structure who suits with mounting key 3.
As shown in fig. 4 to 5, the installation key 3 is a strip structure, the installation key 3 is radially disposed on the outer wall of the casing at the middle lower part of the microphone 1, and a lock nut 9 is disposed at the tail part of the outer wall of the casing at the middle lower part of the microphone 1, so that when not in use, the small-sized speaker 11 is clamped on the installation key 3, and the lock nut 9 is screwed to prevent the small-sized speaker 11 from sliding off the installation key 3, and when in use, the lock nut 9 is first removed, and then the small-sized speaker 11 is pulled out toward the tail part of the microphone 1.
As shown in fig. 4 to 5, the installation key 3 is configured to be an inverted trapezoidal structure, and the installation slot 13 is an inverted trapezoidal structure matched with the installation key 3, so that the installation key 3 and the installation slot 13 are connected in a drawer-type pull-out installation matching manner, and the small-sized sound box 11 is prevented from being damaged and lost due to easy falling off from the microphone 1.
Further, as shown in fig. 1-2, the installation key 3 is a magnet, a magnet or a magnetic conductive material sheet is arranged on the installation clamping groove 13, a shell cover 10 is further arranged on the casing of the middle lower part of the microphone 1, the installation key 3 is covered by the shell cover 10, the small-sized sound box 11 is magnetically attracted on the shell cover 10, and the microphone 1 is more attractive and concise.
Furthermore, the magnet is a rubidium magnet, so that the magnetic attraction strength is improved, and the small-sized sound box 11 is prevented from being damaged and lost due to the fact that the small-sized sound box falls off from the microphone 1 easily.
The number of the small-sized sound boxes 11 is at least two, a loudspeaker 14, a storage battery 8, a wireless signal receiving module 15 and a power amplification module 16 are arranged in each small-sized sound box 11, and the wireless signal receiving module 15 and the power amplification module 16 are connected with the sound box control circuit board 4 in a signal collection mode. After receiving the wireless signal emitted by the microphone 1 according to the present invention, each of the small-sized sound boxes 11 sends the wireless signal to the power amplifier to amplify and drive the speaker 14 unit to sound and broadcast through the built-in wireless signal receiving module 15.
Further, the wireless signal receiving module 15 is a U-segment wireless signal receiving module 15.
The storage battery 8 is a storage battery 8.
As shown in fig. 6, the mobile audio system further comprises a mobile audio 17, and a wireless signal receiving module 15 adapted to the microphone 1 is arranged on the mobile audio 17.
As shown in figure 1, the microphone 1 and the small-sized sound box 11 can be connected together in a magnetic attachment mode to form an independent handheld K song small-sized audio system, a user can carry and use the system conveniently, and the purpose of K song can be achieved by holding the system with one hand.
As shown in fig. 7 to 8, when a plurality of people want to listen to music or sing a song K, the small sound box 11 attached to the handheld microphone 1 can be instantly taken down from the body of the microphone 1 and placed on the desktop or a place close to the listener, so that the whole sound field is widened, or two small sound boxes 11 are taken down on the desktop, and one small sound box 11 is still left on the handheld microphone 1 of the singer and can be listened by the singer.
