Description

Inner bracket horn structure

The invention relates to an inner bracket horn structure, in particular, the design simplification can effectively reduce the height reduction volume of the overall combination of the horn, and utilize the auxiliary of the inner bracket to stabilize the vibration of the voice coil, and appropriately enhance the bass response to improve the pronunciation quality.

According to the design, the design of the new generation of LCD TVs has become more and more light and thin, but the demand for audio and video textures is increasing day by day. Therefore, the related audio and video equipments must be high-end in addition to the audio itself, and the speakers of the terminal output devices. It is also an important factor in determining the sound quality.

As shown in Fig. 1, the combined structure of the conventional horn has an enlarged opening in front of the outer casing and a magnetic back (round iron) in the rear, and a voice coil in the middle of the magnetic return, in the enlarged opening and the voice coil of the outer casing. A diaphragm is interposed between the diaphragms, and an elastic wave plate is disposed under the diaphragm. Although the speaker sound quality is good, but the combination volume is large, it is not suitable for the LCD TV with the internal accommodation space becoming very limited. If the speaker size must be relatively reduced in order to match the sound, the sound wave emitted by it cannot effectively reduce the minimum resonance. The frequency causes the output sound to be less than ideal, and it is impossible to balance the dual enjoyment of vision and hearing, which is its biggest drawback.

In view of this, the inventors have carefully studied and improved, and provide an inner bracket horn structure, which mainly includes: a casing with an enlarged opening at the front and a magnetic return at the rear; a voice coil placed in the middle of the magnetic return, and a diaphragm disposed on the enlarged opening of the casing and having an inner diameter and a voice coil; the improved feature is: an elastic wave plate, the outer edge is disposed on the inner step of the outer casing, and the inner hole gap is sleeved on the side wall of the magnetic return, The magnetic back is axially spaced apart from the plurality of slots, and an inner bracket is disposed on the side wall of the voice coil, and the bottom of the inner bracket is disposed at the edge of the inner hole of the elastic wave plate, and the middle bracket is provided with a plurality of joints extending outwardly The foot suspension is above the multiple troughs of the magnetic return; thereby effectively reducing the overall combined height of the horn and reducing the volume, so that the elastic wave plate can lower the middle section (or upper edge) of the side wall provided in the magnetic return, and assisting with the inner bracket When the voice coil is vibrated up and down, the plurality of pins can avoid the multiple slots in and out of the magnetic return, and appropriately increase the vibration amplitude and vibration stability of the horn, and enhance the bass response to improve the pronunciation quality.

In order to further introduce the structural composition and the operation function of the present invention, the following description is in conjunction with the drawings; as shown in the second to fourth embodiments, the inner bracket horn structure of the present invention mainly comprises: a casing 1, An enlarged opening 11 is arranged in the front and a magnetic return 2 is arranged in the rear; a voice coil 3 is placed in the middle of the magnetic return 2; and a diaphragm 4 is placed on the enlarged opening 11 of the casing to adhere the inner diameter to the voice coil 3; The improved feature is: an elastic wave plate 5, the outer edge 51 is disposed on the inner step 12 of the outer casing 1, and the inner hole 52 is sleeved on the side wall 21 of the magnetic return 2, and the magnetic return 2 is axially spaced apart from the plurality of slots 22, and an inner bracket 6, the upper part is disposed on the side wall of the voice coil 3, the inner bracket 6 is disposed at the edge of the inner hole 52 of the elastic wave plate 5, and the inner bracket 6 is provided with a plurality of pins 61 extending outwardly. Just above the plurality of slots 22 of the magnetic return 2; as shown in Figures 3 and 4, when implemented, the inner bore 52 of the elastic wave plate 5 can reduce the gap between the side walls 21 of the magnetic return 2 (or The position of the edge is provided with three slits 22 at equal axial intervals in the axial direction of the upper portion of the magnetic return 2, and the inner bracket 6 is a circular convex frame body, and a small diameter is arranged above the inner bracket 6. The sleeve 62 is adhered to the side wall of the voice coil 3, and a flange 63 having a large diameter is disposed under the inner bracket 6 to be adhered to the edge of the inner hole 52 of the elastic wave plate 5, and the inner bracket 6 is provided with an inverted L-shaped equal angle. The three legs 61 extending outwardly are suspended to suspend the three slots 22 above the magnetic return 2, and the pins 61 of the inner bracket 6 are provided with slots 64 for conducting The sheet 7 is inserted as a solder joint of the speaker wire 71.

Thereby, when the speaker is composed, the magnetic return 2 can be half-sleevely disposed at the bottom of the outer casing 1, and the elastic wave plate 5 can reduce the gap between the middle portion (or the upper edge) of the side wall 21 of the magnetic return 2 to effectively The overall height of the speaker can be reduced to reduce the volume, so as to be placed in a liquid crystal television with limited internal space, or other electrical products with a lighter and thinner shape, and the auxiliary sound coil 3 of the inner bracket 6 can be used to vibrate, resulting in good pronunciation resonance.

Wherein, as shown in Figs. 4 and 5, since the elastic wave plate 5 has a reduced gap, the middle portion (or the upper edge) of the side wall of the magnetic return 2 is disposed, and the elastic wave plate 5 and the voice coil 3 are further provided with an auxiliary The inner brackets 6 are connected to each other, and a plurality of split slots 22 are disposed at intervals above the magnetic return 2, so that the plurality of pins 61 of the inner bracket 6 can be directly extended across the suspension, so when the speaker is output, the inner bracket 6 is used as an auxiliary. The voice coil 3 vibrates up and down, so that the plurality of pins 61 can avoid entering and exiting the plurality of slots 22 above the magnetic return 2, so that the voice coil 3 moves back and forth (or the piston movement), has a good compliance elastic stable vibration, and can appropriately increase the horn. The vibration amplitude and vibration stability enhance the bass response to produce good pronunciation resonance, and the work and sound waves are more coordinated to improve the pronunciation quality.

In summary, the structural design of the present invention can effectively reduce the height and volume of the overall combination of the horn, and utilize the assistance of the inner bracket 6 to stabilize the vibration of the voice coil 3, and appropriately enhance the bass response, so that the sound quality of the horn is more perfect, It is quite progressive, and it is undoubtedly in line with the patent requirements.
