Description

A kind of duct type pressurization sound equipment

Technical field

The present invention relates to a kind of speakers, and in particular to a kind of pressurization speaker of duct type.

Background technique

Speaker is entire sound system and its important component part, is responsible for electric signal being transformed into acoustical signal, with For people ear diameter listen to, that is to say, that speaker is directly come into contacts with the sense of hearing of people, and the sense of hearing of people be it is very sensitive, There is very strong resolving ability to the tone color of complex sound, so often resulting in make speaker that there is preferable sound effect Volume is bigger than normal, not readily portable and transport.

Summary of the invention

In view of this, the present invention provides a kind of duct type pressurization sound equipment, including speaker body, upper end cover and pedestal, It is characterized in that: further including a bend pipe channel, loudspeaker is equipped in the speaker body, speaker is divided into upper and lower two by the loudspeaker A cavity, the upper cavity are connect with lower chamber by the bend pipe channel.

Wherein, the bend pipe channel is located on the outside of speaker body, including top connection, bend siphunculus and lower contact, described Top connection is connect with one end of bend siphunculus, and the lower contact is connect with the other end of bend siphunculus.

Wherein, the section of the bend siphunculus is round, oval, rectangular or polygon.

Wherein, the upper end cover is equipped with end cap interface, and the bend pipe channel is connect with upper end cover by top connection and end cap Mouth connection.

Wherein, the pedestal is equipped with pedestal interface, the bend pipe channel and pedestal and is connected by lower contact and pedestal interface It connects.

Wherein, the loudspeaker is mounted in speaker body towards pedestal direction, the loudspeaker be located at pedestal and upper end cover it Between.

Wherein, sealing element is equipped between the loudspeaker and speaker body.

Wherein, the top of the loudspeaker is equipped with intermediate bulkhead, offers bulkhead through-hole on the intermediate bulkhead.

Wherein, the intermediate bulkhead is equipped with partition waveguide pipe, and the partition waveguide pipe is located in bulkhead through-hole.

Wherein, it is equipped with pedestal waveguide pipe below the loudspeaker, the pedestal waveguide pipe is located on pedestal.

When loudspeaker makes a sound, upper cavity will generate upward thrust, push air-flow, and air-flow carries sound wave and enters to fall Wave duct, from large to small, sound wave is extended in space, while generating certain resistance, and resistance makes air pressure rebound in the vibration of loudspeaker The vibration frequency of film, loudspeaker slows down, and the vibration period is obviously prolonged, and obtains biggish replaying bass function in amplitude smaller part, To expand the replaying bass performance of main sound box.

Air-flow carries sound wave and enters bend pipe channel across wave duct, and by this sound-delivery channel, the extension effect of sound wave is again Primary enhancing, it is mixed with the sound wave on lower chamber when sound wave enters lower chamber from bend pipe channel to obtain preferable voice effect It is combined, is spread out of by funnel-form waveguide pipe on pedestal, during which space reduces and the mixing of sound wave again, produced twice Resistance, it will rebound in the vibrating diaphragm of loudspeaker, shorten the vibration frequency of vibrating diaphragm, again expand main sound box replaying bass function Energy.

After adopting the above technical scheme, the volume of speaker will reduce significantly, while obtaining several times and being equal to same volume Shake effect.
