Problems solved by technology

[0008] However, there is a certain bottleneck in a certain part. For example, audio can achieve good results without a large volume in the high-frequency and mid-frequency parts, but it is very related to the problem of large volume in the low-frequency and ultra-low frequency parts.
However, the existing passive speakers (commonly known as false speakers) are formed by fixing the three parts together by using ready-made rubber edges and drum paper with glue. Therefore, it is not only difficult to ensure the accuracy, but also because the height cannot be reduced. It is impossible to further effectively reduce the volume of the audio under the condition of requiring high quality

Embodiment 1

[0038] Embodiment 1: As shown in Figures 1-3, the base of the passive speaker vibration plate is thermosetting or thermoplastic elastomer, and its shape is in the shape of a square sheet. The middle part of the base body is the main part 1 of the vibrating plate, which is covered with a central load 4 made of plastic or metal. When in use, the main part 1 of the vibrating plate resonates with the box to produce a low-pitched audio effect. The periphery of the base body is a frame part 3 for combining with the box body, and an assembly hole 5 is provided on this part. The vibrating plate can be assembled on the box body through screws and a pressure strip on the frame, so the assembly is very convenient and can be reused. There is perfect airtightness between its own elastic body covering and the box body. The flexible connection part 2 is a thin rubber edge with a thickness smaller than that of the main body part and the frame part, and its surface is curved, connected between...

Embodiment 2

[0040] Embodiment 2: As shown in Figure 4, it differs from Embodiment 1 in that the frame part 3 is coated with iron or rubber or plastic skeleton 6, which is integrally overmolded with the center load body 4 at the same time during production, and its main effect It is to increase the thickness and strength of the frame part 3, which is specifically designed according to the needs of assembling with the box body.

Embodiment 3

[0041] Embodiment 3: As shown in Figure 5, the main difference between it and Embodiment 1 is the thickness difference on the frame part 3. Compared with the frame in Embodiment 1, its thickness is designed to be thinner, so as to adapt to the assembly with the box body need.

Abstract

This invention relates to a passive sound box vibration board including an elastic matrix containing a main body with a central loader at the center of the matrix, a frame part surrounding the matrix and a flexible connection part connecting the main body and the frame part, in which, the vibration board is molded at one run by hot press or injection.

Description

technical field [0001] The invention relates to a passive sound box vibrating plate, in particular to a passive sound box vibrating plate overmolded by an elastic body. Background technique [0002] In the current era of rapid technological progress, the electronics industry is pursuing exquisiteness and compactness. Today's computers, mobile phones and other corresponding products are all like this. However, the corresponding audio industry has also emerged in response to the orientation of such a concept, and the following changes are being made in the current audio development trend: [0003] 1. The energy consumption and size of the speaker are reduced, but the power is required to increase. [0004] 2. The strength of the speaker has changed from the thick and thin in the past, and the increase in strength is relatively more required. [0005] 3. The speaker changes from large to small, and the relative internal volume becomes smaller. [0006] 4. The design power i...
