Abstract

The utility model discloses a multi-cell powering portable sound box including a casing, and a resonance sounder and a master control circuit board which are arranged in the casing, a resonance drive circuit is arranged on the mater control circuit board, and the improvement is that the master control circuit board is powered by at least two serially connected cells. The serially connected multi-cell powering manner is applied to the sound box to supply higher voltage to the sound box and to generate larger power, thereby achieving stronger hearing impact, compared with a conventional single-cell powering sound box, the multi-cell powering portable sound box provided can bring people incomparable hearing experiences.

Description

Many battery powered portable audios
[technical field]
The utility model relates to stereo set, relates in particular to a kind of how battery powered portable audio.
[background technology]
Known transmission sound equipment is to carry out sounding by inductance coil and the loud speaker that is arranged in the sound equipment, this traditional sound equipment, and the source of sound of its loud speaker is point sound source, makes its sounding have directivity, interfere type and spatiality etc.A kind of resonance speaker of people to traditional sound equipment concept understanding of having overturned appearred on the market in recent years, the sonification system of this resonance speaker itself does not have vibrating diaphragm, it utilizes the principle of resonance, audio signal is converted into the audio frequency mechanical oscillation, exports to any hard objects that contacts with it, make this hard objects as the sound production medium sounding, it is gentle in voice evenly, non-directive is 360 ° around sounding, and can form different tamber effects according to different sound production mediums.Yet, combine with the traditional loudspeaker sound equipment of formula of existing Portable resonant sound box or resonance all is to adopt monocell to power, and sound equipment is under high-power requirement, need higher more stable voltage, existing monocell supply power mode can't satisfy this requirement, and the sound effect that causes playing back also can't reach the impact to user's sense of hearing, simultaneously, the capacity of monocell is less, and power-on time is shorter, makes troubles to the user.
[summary of the invention]
The purpose of this utility model is effectively to overcome the deficiency of above-mentioned technology, and a kind of how battery powered portable audio is provided, and this sound equipment cooperates high-power power amplifier, brings incomparable auditory effect to the user.
The technical solution of the utility model is achieved in that a kind of how battery powered portable audio, it comprises housing and is arranged at housing interior resonance sounding device and main control board, main control board is provided with the resonance drive circuit, and its improvement is: described main control board is by the powered battery of at least two series connection.
Also comprise loudspeaker and drive circuit of loudspeaker, described loudspeaker are electrically connected at drive circuit of loudspeaker.
Described resonance drive circuit comprises audio frequency input selection circuit, the first high-pass filtering circuit, low-pass filter circuit, switching circuit and resonance power amplifier; Wherein, described the first high-pass filtering circuit input is connected in the output of audio frequency input selection circuit, the output of the first high-pass filtering circuit is connected in the input of low-pass filter circuit, and the output of described low-pass filter circuit is connected to the input of switching circuit; The output of switching circuit is connected in the input of resonance power amplifier.
The beneficial effects of the utility model are: one, the utility model are applied to many batteries series-fed in the sound equipment (sound equipment that resonance speaker, resonance combine with loudspeaker), can be sound equipment higher voltage is provided, produce larger power, thereby can obtain the more fierce sense of hearing impacts, namely, compare with the sound equipment of traditional monocell power supply, can bring the incomparable sense of hearing of user and experience; Two, loudspeaker and resonance acoustical generator are incorporated into one, can realize the fusion of sound horn and resonance sounding, again by being arranged at the switching circuit in the resonance drive circuit, the break-make of control resonance drive circuit, realize the switching between sound horn and resonance acoustical generator and the loudspeaker synchronous cant, the user can freely select above-mentioned two kinds of sounding patterns according to the different of high bass, brings the user with this and better experiences.
[description of drawings]
Fig. 1 is the utility model theory diagram;
[embodiment]
The utility model will be further described below in conjunction with drawings and Examples.
With reference to shown in Figure 1, the utility model has disclosed a kind of how battery powered portable audio, it comprises housing and is arranged at resonance sounding device and main control board in the housing, and main control board is provided with the resonance drive circuit, and described main control board is by the powered battery of at least two series connection.
Described resonance drive circuit comprises audio frequency input selection circuit 1, the first high-pass filtering circuit 2, low-pass filter circuit 3, switching circuit 5 and resonance power amplifier 4; Wherein, the input of described the first high-pass filtering circuit 2 is connected in the output of audio frequency input selection circuit 1, the output of the first high-pass filtering circuit 2 is connected in the input of low-pass filter circuit 3, and the output of described low-pass filter circuit 4 is connected to the input of switching circuit 5; The output of switching circuit 5 is connected in the input of resonance power amplifier 4.In this resonance drive circuit, take out by the low frequency signal of low-pass filter circuit 3 with output in the audio frequency input selection circuit 1, after adjusting equilibrium, supply with resonance power amplifier 4, send bass by resonance.And pass through the break-make that switching circuit 5 is controlled the resonance drive circuits, realize the independent sounding of loudspeaker resonance acoustical generator or resonance sounding device and loudspeaker synchronous cant.
In addition, also comprise loudspeaker and drive circuit of loudspeaker, described loudspeaker are electrically connected at drive circuit of loudspeaker.Described drive circuit of loudspeaker comprises the second high-pass filtering circuit 6 and loudspeaker power amplifier 7, the input of described the second high-pass filtering circuit 6 is connected in the output of audio frequency input selection circuit 1, the output of the second high-pass filtering circuit 6 is connected in the input of loudspeaker power amplifier 7, the second high-pass filtering circuit 6 takes out the high-frequency signal of output in the audio frequency input selection circuit 1, add in the loudspeaker power amplifier 7, send high pitch by loudspeaker.The present embodiment, loudspeaker and drive circuit of loudspeaker are respectively two, and two loudspeaker form left and right acoustic channels by drive circuit of loudspeaker separately.Further, the output of switching circuit 5 also is connected in the input of described loudspeaker power amplifier 7, low-pass filter circuit 3 with audio frequency input selection circuit 1 in the low frequency signal of output take out, when supplying with resonance power amplifier 4 through adjusting after the equilibrium, also this low frequency signal can be added to loudspeaker power amplifier 7, send bass by loudspeaker.
The utility model is applied to many batteries series-fed in the sound equipment, can be sound equipment higher voltage is provided, and produces larger power, thereby can obtain the more fierce sense of hearing impacts, that is, compare with the sound equipment of traditional monocell power supply, can bring the incomparable sense of hearing of user and experience; Two, loudspeaker and resonance acoustical generator are incorporated into one, can realize the fusion of sound horn and resonance sounding, again by being arranged at the switching circuit in the resonance drive circuit, the break-make of control resonance drive circuit, realize the switching between sound horn and resonance acoustical generator and the loudspeaker synchronous cant, the user can freely select above-mentioned two kinds of sounding patterns according to the different of high bass, brings the user with this and better experiences.
