Embodiment 1

[0026] Such as Figure 5 as shown, Figure 5 A-d among is the construction schematic diagram of the aluminum ribbon loudspeaker of the present embodiment, Figure 5 e is Figure 5 The longitudinal sectional view of d, the aluminum ribbon loudspeaker includes a strip-shaped aluminum ribbon 2 and a magnetic field parallel to the width direction of the aluminum ribbon, the magnetic field contains or basically includes the aluminum ribbon 2, and audio current can be fed in along the length direction of the aluminum ribbon, and the aluminum ribbon is surrounded by The edge is fixed on the support 1, and there is a ring-shaped indentation fold 3 near the support around the edge of the aluminum strip 2, and the ring-shaped indentation fold 3 is located in the magnetic field.

preparation example 1

[0027] Preparation Example 1: In a 100×10×5mm plastic bracket 1 (wall thickness 0.8mm, such as Figure 5 As shown in a), a 10mm wide and 10 micron thick aluminum strip 2 is glued to the opening, and the two ends are reserved for lead wires ( Figure 5 b) Put it into the mold, mold an approximately semicircular indentation with a width of 2 mm and a depth of 1 mm near the bracket around the edge of the aluminum strip, and the indentation forms a ring-shaped indentation ring 3, such as Figure 5 As shown in c, according to Figure 5 As shown in d and e, insert the bracket with aluminum tape into the magnetic circuit 8, the magnetic pole surface of the magnetic circuit 8 is 100×5mm, and the distance between the magnetic poles is 10.5mm, forming a permanent magnetic field approximately 100×5×10.5MM, The direction of the magnetic field is in the direction of 10.5, and the aluminum ribbon diaphragm is basically located in the middle of the magnetic field, that is, a new type of sil...

Embodiment 2

[0029] Such as Image 6 with Figure 7 as shown, Image 6 The a-d in the present embodiment is the construction diagram of the Haier type pneumatic aluminum ribbon loudspeaker, the Haier type pneumatic aluminum ribbon loudspeaker includes a strip-shaped aluminum strip 4 and a magnetic field parallel to the width direction of the aluminum strip, and can be fed in along the length direction of the aluminum strip. Audio current, the edges around the aluminum strip 4 are fixed on the support 6, the long side of the support 6 is wavy, the joint between the edge of the support 6 and the lengthwise edge of the aluminum strip is wavy, and the aluminum strip 4 is fixed on the wavy support 6 , so that the aluminum strip 4 bends in a wave shape along the length direction, and each of the two long sides of the aluminum strip 4 near the inner edge of the bracket 6 has an indentation ring 5 along the length direction of the aluminum strip.

Abstract

The invention discloses an aluminium strip speaker which comprises a bar aluminium strip and a magnetic field parallel to the aluminium strip in the width direction, wherein the tone current is fed back along the length direction of the aluminium strip; the peripheral brim of the aluminium strip is fixed on a bracket; a plurality of annular impress edges are arranged on the aluminium strip near the peripheral brim of the bracket. Another technical scheme is that a Haier pneumatic aluminium strip speaker comprises the bar aluminium strip and the magnetic field parallel to the aluminium strip in the width direction; and the tone current is fed back along the length direction of the aluminium strip. The aluminium strip speaker is characterized in that the peripheral brim of the aluminium strip is fixed on the bracket; the joint of the brim of the bracket and the brim of the length direction of the aluminium strip forms a wave shape; the aluminium strip is fixed on the waveform bracket, so that the aluminium strip is curved in a waveform shape along the length direction; and the plurality of annular impress edges are arranged on the aluminium strip. It can be seen that a vibrating diaphragm of the aluminium strip speaker can be kept light; the aluminium strip speaker has the advantages of good high-frequency response and simple magnetic circuit, and the problem of the acoustic short circuit can be solved.

Description

Technical field: [0001] The invention relates to a loudspeaker, in particular to an aluminum ribbon loudspeaker. Background technique: [0002] Ribbon speakers are a very old design, dating back to 1920, and are also called ribbon speakers because the diaphragm is usually an aluminum ribbon. The principle of the aluminum ribbon speaker is as follows: figure 1 As shown, the aluminum strip placed in the permanent magnetic field is fed with audio current, and under the action of electromagnetic force, the aluminum strip vibrates up and down to produce sound. The practical aluminum ribbon speaker is usually a meandering aluminum ribbon diaphragm, because it can provide a reasonable amplitude of the diaphragm, such as figure 2 shown. And it is said that the twists and turns can provide additional rigidity of the diaphragm to resist split vibration. At the same time, the aluminum ribbon diaphragm of various aluminum ribbon speakers often sees a variety of pressed patterns such...
