Description
Technical Field
The utility model relates to a music strong sound box structure.
Background
The speaker, which we often speak, is usually the speaker playing music. The objective of the music speaker is to make the sound pleasant, so that the music speaker is required to have small distortion and wide frequency band from the objective index. A speaker unit is difficult to cover whole audio frequency channel, and in order to satisfy the index, most music audio amplifier adopts the design of two speaker units of bass unit and high pitch unit, and high-grade sound system audio amplifier adopts more speaker unit designs. In order to ensure good sound quality, the electroacoustic conversion efficiency is sacrificed in the music sound box, and the sensitivity is generally about ninety decibels.
Different from a music sound box, a sound amplifying product with very high electroacoustic conversion efficiency, namely a megaphone (or a loud sound box) is widely used in the market for megaphone or alarm signal playing, mainly pursuing the megaphone to be far away and sound. Compared with the music loudspeaker box with the same power level, the sound propagation distance is increased by three to five times. The sensitivity of the device is usually more than one hundred decibels, and the device can be used as a battery power supply product, so that the electric energy is greatly saved, and the endurance time can be obviously improved.
The megaphone sacrifices the tone quality in order to ensure the sensitivity and the sound pressure level, and the distortion degree and the frequency band index of the megaphone are poor.
In public security, armed police, liberation army, and each transportation hub such as station, pier, airport, and very many units, two kinds of public address products of music audio amplifier and megaphone are widely used simultaneously. When many troops go out to execute tasks, the troops carry the two products with the troops, and the troops are inconvenient to carry and manage.
SUMMERY OF THE UTILITY MODEL
Aiming at the defects in the prior art, the utility model aims to provide a music strong sound box structure which can simultaneously have the functions of high-sound-quality music playing and high-sound-pressure calling.
The technical scheme adopted by the utility model for solving the technical problems is as follows:
music strong sound case structure, including the audio amplifier body, and install in this internal speaker unit group of audio amplifier, speaker unit mounting hole has been seted up to the front portion of audio amplifier body, speaker unit group installs in speaker unit mounting hole, speaker unit group is including music speaker unit and strong sound speaker unit, music speaker unit is equipped with more than one, and installs respectively in speaker unit mounting hole.
Preferably, the music speaker unit includes a woofer unit and a tweeter unit.
Furthermore, the loudspeaker unit mounting holes comprise a first mounting hole for mounting the woofer unit and a second mounting hole for mounting the tweeter unit.
Furthermore, the first mounting hole is a circular mounting hole, and the second mounting hole is a trapezoidal mounting hole.
Preferably, the first mounting hole has a smaller hole area than the second mounting hole.
Preferably, the depth of the hole in the first mounting hole is greater than the depth of the hole in the second mounting hole.
Preferably, the first mounting hole is located below the second mounting hole.
Preferably, the woofer unit is arranged in the circular mounting hole, and the tweeter unit is located in the trapezoidal mounting hole.
Preferably, the loud speaker unit is arranged in the trapezoidal mounting hole and is coaxially arranged with the high pitch loudspeaker unit.
Preferably, the loud speaker unit and the loudspeaker unit ports of the high pitch loudspeaker unit are both arranged at the second mounting hole.
On the sounding surface of the music sound box, the positions of the music speaker units are rearranged, and the speaker units and the structure of the megaphone are added to form the music loud sound box. The music strong sound box is provided with a mode switching device which can be a switch, a knob, a key and the like.
The selection is switched between two working modes of music and strong sound. Under the music mode, the sounding is mainly performed by the music loudspeaker, and a small amount of loudspeaker energy is shout, so that the sound thickness can be effectively improved, and the sound listening feeling is more real. The frequency dividing point of the traditional music sound box with two frequency divisions is just in the voice frequency band, the voice of a person is torn into two sections, the frequency band of the loudspeaker is also in the voice section, and the defect is just made up. Because the loudspeaker of shouting can cover a part of the frequency band of the high pitch loudspeaker in the music loudspeaker, the power of the high pitch loudspeaker can be shared, and the risk of damaging the high pitch loudspeaker is reduced. Under the strong mode, the sound production is mainly with shouting the speaker, assists with the music speaker energy, and the time-frequency band is wider when owing to two kinds of speakers simultaneous working, so can show to improve and shout tone quality and shout the distance, promote the language definition.
The utility model has the beneficial effects that:
through the setting that adopts the speaker unit mounting hole, carry out the installation of speaker unit group via the speaker unit mounting hole, and the speaker unit group includes music speaker unit and loud speaker unit, combines together the music speaker unit of high tone quality and the loud speaker unit of high diffusion to install and carry out the integration in the speaker unit mounting hole, is convenient for switch simultaneously in the open air and uses two kinds of speaker units, and the practicality is strong.
