Abstract
The invention provides a drum-type loudspeaker box. The drum-type loudspeaker box comprises a box body, a sound generating device is arranged in the box body; the box body comprises a cylindrical side wall, the top end and the bottom end of the side wall are respectively provided with a top opening and a bottom opening, a longitudinal section of the side wall is arc, and an arc center of the arch is arranged in the cylindrical side wall. Through the drum-type loudspeaker box provided by the invention, a modern scientific product loudspeaker box and the traditional percussion instrument are mutually combined so as to form a loudspeaker box with the appearance similar to a drum; the loudspeaker box not only has professional loudspeaker box effect, but also can fuse with the traditional architecture style, so that the appearance is no more abrupt and discordant. And meanwhile, the loudspeaker box adopts a drum-shaped box body, the side wall is arc, when a loudspeaker generates sound, the sound transmitted to the box body is hard to produce standing wave due to the reflection of the sound; therefore, the middle-high frequency made by the loudspeaker is clean and transparent, the low frequency is vigorous and powerful, and the lower limit of the lower frequency is improved to a large extent in comparison with a normal full-frequency loudspeaker box.
Description
Technical field
The present invention relates to sound-box device technical field, especially relate to a kind of cydariform audio amplifier being placed in ancient building indoor and outdoor.
Background technology
The effect of audio amplifier is that audio frequency electric energy is converted to corresponding acoustic energy, and it is radiated space.Wherein, audio amplifier, as a kind of electronics technology product, possesses the feature such as diversity, personalization.Therefore, at some special occasions, as, in the indoor and outdoor of heritage buildings, comprise temple, house etc., the audio amplifier with " modern sense " is put within it, always give antipathetic, the inharmonic sensation of people's one, the total tune not only destroying environment is beautiful, and makes whole place seem very not solemn.
In order to avoid above-mentioned shortcoming, audio amplifier combines with the inherent structure put in environment by people, with avoid this kind inharmonious, such as, audio amplifier to be embedded in wall, in tree crown or mode in birdcage etc., as much as possible audio amplifier to be hidden.But, adopt this kind of mode can have influence on the voice quality of audio amplifier, the sound " unpleasant " that audio amplifier is sent.
Summary of the invention
The object of the present invention is to provide a kind of cydariform audio amplifier, to solve the voice quality having influence on audio amplifier existed in prior art, the technical problem of the sound that audio amplifier is sent " unpleasant ".
A kind of cydariform audio amplifier provided by the invention, comprises casing, is provided with sound-producing device in described casing;
Described casing comprises sidewall cylindrically, and the top of described sidewall and bottom are respectively equipped with top end opening and bottom end opening, and the longitudinal cross-section of described sidewall is curved, and its arc core is located at the inside of the described sidewall of tubular;
Described sound-producing device comprises input socket, frequency divider and loud speaker, described top end opening and described bottom end opening place are respectively equipped with top baffle and bottom baffle, reinforcement bracing frame is provided with between described top baffle and described bottom baffle, described input socket connects described frequency divider, described frequency divider is connected with described loud speaker, described input socket, described frequency divider and described loud speaker are all located on described reinforcement bracing frame, described top baffle is provided with paraphase hole and manhole, and the edge of the conical horn of described loud speaker is connected with described manhole.
Further, described top baffle is coated with yellowish pink entrant sound net.
The Main Function that top baffle arranges entrant sound net is the effect playing decoration, and does not affect the sounding of loud speaker while decoration.Wherein, entrant sound net is set to yellowish pink, makes it more close to the profile of drum, generally, the eardrum of the sounding at the two ends of drum is yellowish pink, therefore, adopts yellowish pink entrant sound net more vivid.
Further, described top end opening place is provided with annular parcel limit, and the inward flange on described annular parcel limit is fixedly connected with described top baffle by adhesive, and the outward flange on described annular parcel limit is fixedly connected with the outer wall of described sidewall by bubble nail;
The inside edge on described annular parcel limit is provided with ring-shaped platform, and the edge of described entrant sound net is located on described ring-shaped platform.
Annular parcel limit act as decoration function, annular parcel limit outward flange by bubble nail and sidewall link together, wherein, annular parcel limit is set to yellowish pink equally, identical with entrant sound net, thus make entrant sound net wrap up limit and form with annular the eardrum being similar to piece of meat look, profile is more vivid.
The inward flange on annular parcel limit is fixed by adhesive, and the outside of entrant sound net is provided with strong magnets, and strong magnets is inhaled on the peg on the baffle of top, thus entrant sound net is fixed, this kind of mode, can be fixed entrant sound net, meanwhile, also can dismantle at any time, maintain easily maintenance.
Further, described input socket is provided with audio input interface, and described audio input interface is located at the outside of described casing through described sidewall.
Preferably, audio input interface is arranged on the arc top place of the sidewall of arc, and namely audio input interface is positioned at outermost end, easy to operate when external audio signal, and can not affect the normal use of audio amplifier.
Further, be provided with power amplifier in described casing, described power amplifier is connected with described input socket.
By arranging power amplifier, thus make audio amplifier be active audio amplifier, the equipment such as sound console, power amplifier need not be joined separately again, just can realize multichannel wired, wireless microphone, the broadcasting of the music such as the input of multichannel source of sound and USB flash disk SD card and voice, brings larger convenience by use.
Wherein, the interface of power amplifier is arranged on the sidewall of casing.
Further, described bottom end opening is provided with yellowish pink artificial leather capping, and the external diameter of described artificial leather capping is greater than the external diameter of described bottom end opening, and being convenient to of described artificial leather capping is fixedly connected with the outer wall of described sidewall by bubble nail.
