Entertainment sound box with shaking sound
Technical Field
The invention relates to the field of audio equipment, in particular to an entertainment sound box.
Background
In the field of entertainment activities, music and dance are often combined, and in an easily enjoyable environment, a human body often tends to swing following the music, thereby forming various forms of dance. Particularly, when immersed in music with strong rhythm, limbs usually swing rhythmically with the music, and in the process, in order to further improve the rhythm, the music is usually expected to have fluctuating shaking sense, for example, the volume of the music is fluctuated with the swing of the body to form a fluctuating feeling; in this regard, there is currently no sound box that can form a good interaction with the body shape.
Disclosure of Invention
In view of the above problems, an object of the present invention is to provide a tremble entertainment sound box, which can form a tremble effect with a large and small volume in the swinging process of a human body, so as to improve the rhythm of music to a large extent.
The technical scheme adopted by the invention for solving the technical problems is as follows: the buffeting entertainment sound box comprises a shell with a handle, wherein a loudspeaker and a music playing module are arranged in the shell; the music playing module is output to a power amplification module of the loudspeaker and is connected to the loudspeaker through a tremble module; the sound-shaking module comprises a cavity body, wherein more than 4 impact switches and a ball are arranged in the cavity body; the impact switch is kept connected for a fixed time after being impacted by the ball; each impact switch is connected with a resistor in series and then connected in parallel to form a parallel switch group, and the parallel switch group is connected to the power amplification module and the connecting line of the audio coil of the loudspeaker.
Preferably, the music playing module comprises an audio file memory and a decoding playing module; and/or a Bluetooth receiving module and a decoding playing module; therefore, built-in music can be directly played or music received by Bluetooth can be played.
Preferably, the cavity is a spherical cavity or a round box-shaped cavity, so that the cavity has good symmetry in the cavity, and the collision probability of each collision switch is equivalent to that of a round ball.
Preferably, the time for keeping the impact switch on every time is 2 s-3 s.
Preferably, the contact of the impact switch comprises a fixed contact attached to the wall of the cavity body, and an elastic arched moving contact crossing two sides of the fixed contact, the center of the arched moving contact is provided with a contact facing the fixed contact, and the arched moving contact is contacted with the fixed contact through deformation after being impacted by the ball, so as to trigger a time-delay switch-on module in the impact switch, and the impact switch is kept on for a fixed time.
The invention has the beneficial effects that: in the entertainment process of the buffeting entertainment sound box, the sound box can be held by hand to start music, and along with the swinging of a body, balls in a cavity body irregularly collide with each impact switch, so that a parallel branch where the collided impact switch is located is connected for a period of time, the output impedance of a power amplifier is reduced in the period of time, and the volume of the sound box is increased; in the same time, the more parallel branches are connected, the larger the sound volume of the sound box is; therefore, with the rhythm, rhythm and body swing, the sound box can be matched to generate the sound which is suddenly high and suddenly low, the rhythm of the music can be improved to a greater extent, and the entertainment fun is increased.

Detailed Description
In the embodiments shown in fig. 1 to fig. 3, the tremble entertainment sound box includes a casing 1 with a handle, and a speaker 2 and a music playing module are disposed in the casing 1; the music playing module outputs the music to the power amplifier module 21 of the loudspeaker 2, and then is connected to the loudspeaker 2 through a tremble module.
An embodiment of the dither module is shown in fig. 2 and fig. 3, and includes a cavity body 41, in this embodiment, the cavity body 41 is a round box-shaped cavity, and 5 impact switches 42 and a round ball 43 are uniformly distributed in the cavity body 41; the impact switch 42 is kept on for a fixed time after being impacted by the round ball 43; as shown in fig. 2, each of the impact switches 42 is connected in series with a resistor R, and then connected in parallel to form a parallel switch group, and the parallel switch group is connected to a connection line between the power amplifier module 21 and the audio coil 22 of the speaker. Thus, the greater the number of bump switches 42 that remain on, the lower the total resistance of the parallel switch set.
In the above-mentioned tremble sound amusement loudspeaker box, the music playing module includes an audio file memory and a decoding playing module; and/or a Bluetooth receiving module and a decoding playing module; therefore, built-in music can be directly played or music received by Bluetooth can be played.
In the above-mentioned jittering entertainment sound box, the time for which the impact switch 42 is kept on every time is 2 s-3 s; as shown in fig. 3, the contact of the impact switch 42 includes a fixed contact 421 attached to the wall of the cavity, and an elastic arched moving contact 422 crossing both sides of the fixed contact 421, the center of the arched moving contact 422 has a contact facing the fixed contact 421, and after being impacted by the ball 43, the arched moving contact 422 contacts the fixed contact 421 through deformation to trigger the delay switch-on module in the impact switch 42, so that the impact switch 42 is kept on for a fixed time; the delay-connected module belongs to a conventional electronic module, and has more types and models, which are not described in detail.
In the entertainment process of the buffeting entertainment sound box, the sound box can be held by hand to start music, and along with the swinging of a body, the round balls 43 in the cavity body 41 irregularly collide with the impact switches 42, so that the parallel branch where the collided impact switches are located is connected for a period of time, the output impedance of the power amplification module 21 is reduced in the period of time, and the volume of the sound box is increased; in the same time, the more parallel branches are connected, the larger the sound volume of the sound box is; therefore, with the rhythm, rhythm and body swing, the sound box can be matched to generate the sound which is suddenly high and suddenly low, the rhythm of the music can be improved to a greater extent, and the entertainment fun is increased.
The invention has the beneficial effects that: the invention has the beneficial effects that: the above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
