Detailed Description
Referring to fig. 1, the utility model relates to a big sound cavity bluetooth speaker.
Referring to fig. 2, a big sound chamber bluetooth speaker, including main casing body 1, main casing body 1 is the three-dimensional annular of rectangle, and the preceding face shell installation position 12 that is equipped with of the three-dimensional annular of rectangle is equipped with dorsal scale installation position 11 at the back, and the top is equipped with top cap installation position 13, and the left and right sides is equipped with handle fixed orifices 14 respectively, install face shell 121 in face shell installation position 12, dorsal scale installation position 11 installs dorsal scale 112, install top cap 132 in top cap installation position 13, face shell 121, dorsal scale 112 and top cap 132 enclose with main casing body 1 and close and form a big sound chamber.
Referring to fig. 3, a woofer 122 and a tweeter 123 are installed at the inner side of the face housing 121, and the tweeters 123 are installed at both sides of the woofer 122; the left end of the back shell 112 is provided with a battery position 114, the middle part of the back shell 112 is provided with a socket position 112, the middle part of the back shell 112 is provided with a main board position 115, a battery 117 is installed in the battery position 114, a socket board 113 is installed in the socket position 112, a main board 116 is installed in the main board position 115, a key board 131 is installed below the top cover 132, a decoration panel 133 is installed above the top cover 132, and a key cap 134 is installed above the decoration panel 133.
Referring to fig. 3, the key sheet 131, the socket sheet 113, the woofer 122, and the tweeter 123 are electrically connected to the main board 116, respectively.
The utility model discloses under the prerequisite that does not change the audio amplifier volume, have enough big sound chamber in order to protect, be convenient for circling round of sound, set up the various subassemblies of audio amplifier respectively and fix in the inboard of face-piece 121 and dorsal scale 111 to and the outside of top cap 132 is fixed.
The handle 5 is arranged in the handle fixing hole 14, so that the loudspeaker box is convenient to carry.
The sound cavity can adjust the output frequency response curve of the loudspeaker to a certain extent, and the quality of the sound quality of the music sound is greatly influenced by changing the high and low tone effects of the music sound through adjusting the parameters of the sound cavity. The timbres of the same sound source and the same loudspeaker playing effects in different sound cavities are likely to differ greatly, some are more pleasant and some are monotonous, and the music sound can be more pleasant due to the reasonable sound cavity design. The sound cavity has great influence on the tone quality of the low-frequency part of the music sound, the bass becomes more prominent the more left the low-frequency wave crest, and the music sound is subjectively more pleasant. Generally, as the volume of the rear sound cavity is increased, the low-frequency wave peak of the frequency response curve is moved leftward, so that the low-frequency characteristic can be improved. Various elements of the sound box are reasonably arranged on the inner sides of the front shell and the back shell of the sound box, so that the sound cavity of the sound box is enlarged as much as possible, and the sound quality of the sound box is more pleasant.
