Abstract

The utility model discloses a resonance speaker with double voice coils, which comprises a casing, a base, a magnet and voice coils. The casing is connected with the base through a fastening piece, and the magnet and the voice coils are arranged in an inner cavity of the casing. The resonance speaker with double voice coils is characterized in that a first vibration conducting body capable of moving vertically relative to the base is arranged below the base, a second vibration conducting body capable of moving vertically relative to the casing is arranged inside the casing, and an opening is arranged at the central position of the base. The first vibration conducting body and the second vibration conducting body are connected with each other through a fastening piece penetrating through the opening. A frame is connected with the first vibration conducting body, the voice coils are sleeved on the frame, the magnet is arranged in the frame, a magnetic conducting body is sleeved on the magnet, and the voice coils are double voice coils. The resonance speaker has the advantages that the resonance speaker adopts the structure of the double voice coils so that under the condition of same magnetic energy, the resonance speaker with double voice coils is several times higher in electroacoustic conversion efficiency, louder in sound, strong in middle and low pitch, and perfect in hearing effects.

Description

Double-voice coil type resonance sound equipment

[technical field]

The utility model relates to PA-system, particularly a kind of double-voice coil type resonance sound equipment.

[background technology]

Occurred a kind of resonance sound equipment of people to traditional sound equipment concept understanding of having overturned in recent years on the market, the sonification system of this resonance sound equipment itself does not have vibrating diaphragm, and 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 sounding medium sounding; It is gentle in voice evenly; Non-directive is 360 ° around sounding, and can form different tamber effects according to different sounding media.The volume of resonance sound equipment is little, can arbitrarily put, and its only needs be connected with audiogenic devices such as computer, MP3, MP4, MD, CD, DVD player, mobile phones, just can let hard objects such as desk in the daily life, door, window, floor become natural sound equipment; Yet; Resonance sound equipment of the prior art generally all is a single-tone circle resonance sound equipment; Its electro-acoustic conversion efficiency is lower, sound is little, more effect is bad, also relatively poor to user's auditory effect for middle bass, and its whole acoustics can not satisfy the requirement of most of young consumers.

[utility model content]

The purpose of the utility model is to provide a kind of can effectively overcome above-mentioned deficiency, double-voice coil type resonance sound equipment that high, loud, the middle bass effect of electroacoustic transformation efficiency is good.

The technical scheme of the utility model is achieved in that it comprises shell, base, magnet, voice coil loudspeaker voice coil; Said shell is connected through securing member with base, and magnet and voice coil loudspeaker voice coil are arranged at shell inner cavity, and its improvement is: said base below is provided with one can first lead the body that shakes with respect to what base moved up and down; Enclosure is provided with one can second lead the body that shakes with respect to what shell moved up and down; The center is provided with an opening on the base, first lead the body and second that shakes lead shake body through one pass opening securing member be connected, said first leads and is connected with a skeleton on the body that shakes; Voice coil loudspeaker voice coil is sheathed on the skeleton; Said magnet is installed in the skeleton, is arranged with magnetic conductor on the magnet, and said voice coil loudspeaker voice coil is the double-tone circle;

In the said structure, said first leads the body that shakes, second leads to shake and is provided with the distortion rubber cushion between body and the base;

In the said structure, said second leads the body that shakes is provided with rubber cushion;

In the said structure, said shell is that metal material is processed.

The beneficial effect of the utility model is: the double-voice coil type resonance sound equipment of one of which, the utility model; Its base below is provided with one can first lead the body that shakes with respect to what base moved up and down; Enclosure is provided with one can second lead the body that shakes with respect to what shell moved up and down; And adopt the double-tone coil structures, make under equal magnetic energy condition, double-voice coil type resonance sound equipment resonates with respect to single voice coil type, and the sound equipment electro-acoustic conversion efficiency is multiplied, sound is bigger, middle bass is stronger, auditory effect is more perfect; Two, first lead the body that shakes, second and lead to shake and be equipped with the distortion rubber cushion between body and the base in the base, so, reduced the resistance of vibration, help leading the body that shakes and move up and down, the transformation efficiency that further improves electroacoustic is higher, and acoustics is better; Three, second lead the body that shakes and be provided with rubber cushion, this design can effectively prevent to lead the noise that the body vibration produces that shakes; Four, its shell is a metal shell, and the effect of sound equipment has been strengthened in the interference of maskable external electromagnetic field.

[embodiment]

Below in conjunction with accompanying drawing and embodiment the utility model is done further to describe:

With reference to shown in Figure 1, the double-voice coil type resonance sound equipment that the utility model discloses, it comprises shell 1, base 2, magnet 3, voice coil loudspeaker voice coil 4; Shell 1 and base 2 are connected through securing member; Magnet 3 and voice coil loudspeaker voice coil 4 are arranged at shell 1 inner chamber, and base 2 belows are provided with one can first lead the body 5 that shakes with respect to what base 2 moved up and down, and shell 1 inside is provided with one can second lead the body 6 that shakes with respect to what shell 1 moved up and down; The center is provided with an opening on the base 2; First lead the body 5 and second that shakes lead shake body 6 through one pass opening securing member 7 be connected, first leads and is connected with a skeleton 8 on the body 5 that shakes, voice coil loudspeaker voice coil 4 is sheathed on the skeleton 8; Magnet 3 is installed in the skeleton 8, is arranged with magnetic conductor 9 on the magnet 3.

With reference to shown in Figure 2; The voice coil loudspeaker voice coil 4 of the utility model adopts the double-tone circle, and the double-tone circle comprises two unicoils 12 and four lead ends 13 that are surrounded on the skeleton 8, with reference to shown in Figure 3; Circuit connecting relation figure for four lead ends 13 of twin coil; Circuit output end is connected with four lead ends 13, and promptly output OUT1+, OUT1-are connected with one of them monocoil two lead end of twin coil, and output OUT2+, OUT2-are connected with another monocoil two lead ends of twin coil.
