Abstract
The utility model discloses a miniature resonance sound box, which comprises a box body, a loudspeaker unit and a resonance loudspeaker driver. The loudspeaker unit and the resonance loudspeaker driver are fixed in the box body. The loudspeaker unit is disposed on the resonance loudspeaker driver. A round diaphragm is mounted on the loudspeaker unit. The round diaphragm is provided with an audio signal line which contains a large spiral section, a first small spiral section and a second spiral section. The large spiral section is arranged between the first small spiral section and the second small spiral section. A conical pronunciation cavity is arranged below the round diaphragm. In comparison with the prior art, the design provided by the utility model is adopted to make the sound coming from the loudspeaker more concentrated and raise timbre. As the conical pronunciation cavity is arranged below the round diaphragm, problems of frequency distortion, phase distortion and harmonic interference in the prior art can be solved.
Description
Technical field
The utility model relates to audio amplifier, especially a kind of miniature resonance audio amplifier.
Background technology
Along with high-speed development of science and technology, audio amplifier is as the terminal of whole sound system, and its effect is that the audio frequency electric energy is converted to corresponding sonic energy, and it is radiated the space.Audio amplifier is the extremely important part of sound system, because it is being undertaken and the signal of telecommunication is transformed into acoustical signal is directly listening to this mission critical for people's ear.And the resonance audio amplifier is a novel product, the audio amplifier that does not have loudspeaker, extremely rare on the market, the appearance of resonance audio amplifier, its aim is exactly the limitation of common audio amplifier audio of breaking traditions, because the transaudient of common audio amplifier is to reach the audio effect through loudspeaker level concussion transfer of air, and certain limitation directive property is arranged; The resonance audio amplifier just can be not like this, and the resonance audio amplifier can be propagated with 360 ° of frequencies.Yet the miniature or small-sized resonance audio amplifier in existing being provided with is owing to be subjected to the influence of volume, and can't avoid problem such as disturbing mutually because of frequency distortion, phase distortion and harmonic wave that frequency divider brings.
Summary of the invention
For overcoming the deficiency of prior art, it is outstanding and can 360 ° of miniature resonance audio amplifiers that the frequency balances are propagated that the purpose of this utility model provides a kind of audio that resonates, and simple in structure, low cost of manufacture, be easy to carry about with one.
For achieving the above object, technical scheme provided by the utility model is: a kind of miniature resonance audio amplifier, comprise casing, loudspeaker unit and resonance loudspeaker driver, be fixed in the casing at described loudspeaker unit and the driving of resonance loudspeaker, described loudspeaker unit is arranged on the resonance loudspeaker driver, on described loudspeaker unit, be provided with circular membrane, on described circular membrane, be provided with audio signal wire, described audio signal wire includes big spiral pieces, the first little spiral pieces and the second little spiral pieces, and described big spiral pieces is arranged between the first little spiral pieces and the second little spiral pieces; Have conical pronunciation chamber at described circular membrane.Compared with prior art, the beneficial effects of the utility model are, owing on circular membrane, be provided with audio signal wire, and the audio signal of its big spiral pieces, the first little spiral pieces and the corresponding audio amplifier different frequency of second little spiral pieces section, can make that the sound that sends of loudspeaker is more concentrated, improve tonequality; Owing to have conical pronunciation chamber at circular membrane, can solve the problem that the distortion of prior art medium frequency, phase distortion and harmonic wave are disturbed mutually.
As specializing, described big spiral pieces, the first little spiral pieces and the second little spiral pieces are on same center line.As specializing, the described big spiral pieces and the first little spiral pieces are on same center line, and the angle between the described second little spiral pieces and the big spiral pieces is 30 ° to 65 °.As specializing, described circular membrane is the high resiliency vibrating diaphragm.Owing to be provided with the high resiliency vibrating diaphragm, further strengthened bass effect.As improvement, on described loudspeaker unit, be provided with the metal coating net.As specializing, described casing is a porcelain spare.
Description of drawings
Fig. 1 is a three-dimensional structure diagram of the present utility model.
Fig. 2 is a cut-away view of the present utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is further elaborated.
As illustrated in fig. 1 and 2, a kind of miniature resonance audio amplifier that present embodiment provided, comprise casing 1, loudspeaker unit 2 and resonance loudspeaker driver 3, wherein, described casing 1 is a porcelain spare, be fixed in the casing 1 at described loudspeaker unit 2 and the driving of resonance loudspeaker, described loudspeaker unit 2 is arranged on the resonance loudspeaker driver 3, is provided with circular membrane 4 on described loudspeaker unit 2, and wherein said circular membrane 4 is the high resiliency vibrating diaphragm, owing to be provided with the high resiliency vibrating diaphragm, further strengthened bass effect; On described circular membrane 4, be provided with audio signal wire 5, described audio signal wire 5 includes big spiral pieces 51, the first little spiral pieces 52 and the second little spiral pieces 53, described big spiral pieces 51 is arranged between the first little spiral pieces 52 and the second little spiral pieces 53, wherein, described big spiral pieces 51, the first little spiral pieces 52 and the second little spiral pieces 53 are on same center line; Have conical pronunciation chamber 6 at described circular membrane 4.In addition, on described loudspeaker unit 2, be provided with metal coating net 7,, can play dustproof and crashproof effect owing to be provided with metal coating net 7.The characteristics of miniature resonance audio amplifier are in the present embodiment, owing on circular membrane 4, be provided with audio signal wire 5, and the audio signal of its big spiral pieces 51, the first little spiral pieces 52 and the second little spiral pieces 53 corresponding audio amplifier different frequency sections, can make that the sound that sends of loudspeaker is more concentrated, improve tonequality; Owing to have conical pronunciation chamber 6 at circular membrane 4, can solve the problem that the distortion of prior art medium frequency, phase distortion and harmonic wave are disturbed mutually.
