Abstract

A duocone coaxial loudspeaker relates to loudspeakers and is composed of a high pitch loudspeaker and a low pitch loudspeaker. The duocone coaxial loudspeaker is characterized in that the high pitch loudspeaker and the low pitch loudspeaker are linked with a T iron of the low pitch loudspeaker through a panel and a clamping strap of the high pitch loudspeaker and are fixed through bolts, the T iron of the low pitch loudspeaker is provided with an arc-shaped central hole as a horn of the high pitch loudspeaker, a phase stopper is arranged on the front end of the high pitch loudspeaker, and the phase stopper is extended into the center hole of the low pitch loudspeaker. The duocone coaxial loudspeaker has the beneficial effects that after the phase stopper is installed between high pitch diaphragm and low pitch diaphragm, sound waves of the whole diapason range are sent from one point correspondingly to achieve best effects of natural tone, the coaxiality can be kept, and the quality of the loudspeaker is improved.

Description

High bass coaxial loudspeaker

Technical field

The utility model relates to loud speaker, specifically is a kind of high bass coaxial loudspeaker.

Background technology

Common in the market loud speaker is difficult to the whole range scope of high-quality playback from 20Hz-20KHz mostly, for the whole range scope of high-quality playback, general all is that speaker combination with several different qualities forms, and assembles relatively more difficultly like this, involves great expense.And ripe full-range speaker is rarely found on market, how combination loudspeaker being combined into one structurally is a difficult problem, if high bass magnet is made of one structure, because magnet will satisfy the different requirements of combination loudspeaker simultaneously, and be difficult on the structure cooperate, will certainly cause percent defective to improve greatly, the waste raw material; If with high bass magnet design composition body structure, how assembling between the combination loudspeaker is problem, how to make the perfect stack of high pitch and bass sound wave with regard to a big problem especially, if handle bad, can cause to interfere with each other, cause distortion, have a strong impact on the quality of loud speaker.So how to address this problem and just become the task of top priority.

The utility model content

The technical problem that the utility model solved is to provide a kind of high bass coaxial loud speaker, has not only well solved the assembly problem between the combination loudspeaker, and can make high pitch and the perfect stack of bass sound wave, thereby high-quality sound can be provided.

The technical problem that the utility model solved realizes by the following technical solutions:

A kind of high bass coaxial loudspeaker, combine by high pitch loudspeaker and woofer, it is characterized in that: described high pitch loudspeaker and woofer are that the T iron by the panel of high pitch loudspeaker and clamping plate and woofer is engaged togather, use bolt, the iron horn that the centre bore of arc line type is arranged as high pitch loudspeaker of the T of described woofer, the front end of described high pitch loudspeaker is provided with phase plug, and phase plug extend in the centre bore of woofer T iron.

The inner surface of described horn is an arc line type, and front end is connected mutually with the bass vibrating diaphragm.

Described high pitch loudspeaker bonds together the back by T iron, magnet and clamping plate by glue and panel constitutes, and the centre of described panel is equipped with shake film and voice coil loudspeaker voice coil, and shake film front is provided with phase plug, and phase plug and panel are structure as a whole.

Described phase place is plugged with inside and outside two circles and constitutes, and the outer ring is the arc line type pipe, and inner ring is cylindrical pipe.

All parts of high pitch loudspeaker and woofer all have an axle center.

The beneficial effects of the utility model are that all parts of high pitch loudspeaker and woofer all have an axle center, after phase plug is installed, the perfect stack of high pitch and bass sound wave, the sound wave of whole range scope is equivalent to send from a point, the strong condition of sounding that more meets naturetone, thereby reach best sounding effect, improved the quality of loud speaker.Be connected by bolt between its medium and high pitch loudspeaker and the woofer, sliding phenomenon can not occur.

Description of drawings

Fig. 1 is the structural representation of original high bass combination loudspeaker;

Fig. 2 is a structural representation of the present utility model;

Fig. 3 is the utility model phase plug structural representation.

Embodiment

For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.

As shown in Figure 1, original high bass combination loudspeaker just simply makes up high pitch loudspeaker 1 and woofer 2, both are not easy to keep coaxial like this, be prone to slip, and the high pitch that sends and bass sound wave phase error are big, the sound wave that high pitch loudspeaker sends woofer forms and hinders, and distortion is big, and quality is low.

As shown in Figure 2, a kind of novel high bass coaxial loudspeaker, high pitch loudspeaker 1 and woofer 2 are engaged togather by the panel 3 of high pitch loudspeaker and the T iron 21 of clamping plate 11 and woofer, and be fixing with bolt 4.The centre bore that the T iron center of woofer 2 is shaped on arc line type forms cavity 22, and phase plug 12 is installed on the front end of high pitch loudspeaker 1, and phase plug 12 extend in the cavity 22 of woofer 2.Wherein phase plug 12 has inside and outside two circles to constitute, and outside phase plug is set to the arc line type pipe, and inside is cylindrical pipe.The inner surface of cavity 22 is processed into arc line type horn mouth 23, and front end is a bass vibrating diaphragm 24, leaves gap 25 between phase plug 12 and cavity 22 inwalls.

As shown in Figure 3, the centre of high pitch loudspeaker panel 3 is provided with phase plug 12, and the bottom of phase plug 12 is equipped with high pitch shake film and high pitch voice coil loudspeaker voice coil.

More than show and described basic principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.

Claims
