Embodiment 1

[0048] refer to Figure 1-2 , a sound box: including a sound unit 1 and a box body 2. The box body 2 is a hollow pressure vessel formed by blowing at one time. In this embodiment, the hollow pressure vessel is made of glass, shaped as a sphere, and the thickness of the sphere is 5 mm. Of course, the box body can also be a plastic box body formed by blow molding at one time, which has the same characteristics as the glass box body, and no further description is given.

[0049] Since the box body 2 has the characteristics of a pressure vessel, it is not necessary to make the box body 2 very thick in order to improve the resistance of the box body 2 to the internal air pressure. At the same time, due to the one-time blowing process used by the box body 2 , the characteristics of this process also make it possible to manufacture the thin-walled box body 2 . Therefore, the above two features make the box body light and thin. In this embodiment, the thickness of the box body 2 is...

Embodiment 2

[0058] refer to image 3 , The difference between this embodiment and Embodiment 1 is that the hollow pressure vessel has an inverted pipe 23 facing opposite to the blowing port 21, thereby forming an inverted sound box. It should be pointed out that the shape of the inverter tube 23 is not limited to the one described in this embodiment, as long as the common inverter tubes that meet the requirements of blowing are simple replacements in this embodiment, no further description will be given.

Embodiment 3

[0060] refer to Figure 4-6 , In the traditional speaker design, the box body and the sound unit are considered inseparable, because the drive circuits required by the sound unit must be installed on the box body. With the advancement and development of technology, components such as a driving circuit for driving the sounding unit can be arranged on the sounding unit. Therefore, it becomes possible to replace the cabinet of the speaker.

[0061] In particular, for the present invention, there are a large number of one-time blown pressure vessels on the market, such as airtight cans, lampshades and the like. If these existing pressure vessels can be used, a complete sound box can be formed after the sounding unit is sealed and installed with it, which greatly reduces the cost of producing and designing sound boxes for manufacturers, and also brings more personalized choices to users.

[0062] However, for the structure in Embodiment 1, it is necessary to have threads on the o...

Abstract

The invention provides a box body of a loudspeaker box, and the box body is a hollow pressure vessel formed by one-step blowing. The invention provides the box body of the loudspeaker box, the box body is formed by one-step molding, the tightness is relatively good, and the box body can be made very thin, so that the weight of the whole loudspeaker is reduced. The invention provides the box body of the loudspeaker box, and the box body thereof can be made by multiple existing products to replace the box body of a traditional loudspeaker box. The invention provides the box body of the loudspeaker box, and a sound producing unit is directly in tight coupling with a blowing opening. The invention provides the box body of the loudspeaker box, and a sealing element is arranged on the sound producing unit, so that when the sound producing unit is installed with the box body, the sealing element is sealed with an opening of the box body, so that the sealing installation is finished.

Description

technical field [0001] The invention relates to a box body of a sound box and a sound box. Background technique [0002] A traditional speaker consists of a box and a sounding unit. The box provides a closed cavity for the sounding unit; when the sounding unit makes sound, the air in the cavity is driven by it to resonate. Therefore, the box needs to take into account the resistance to internal air pressure. In the traditional design, the method of making the box thicker and heavier is used to increase the pressure resistance of the box to the air inside. The disadvantage of this approach is that it greatly increases the weight of the cabinet itself, resulting in an increase in cost and a lack of mobility of the cabinet. Contents of the invention [0003] The main technical problem to be solved by the present invention is to provide a box body of a sound box, which is molded at one time and has better sealing performance, and the thickness of the box body can be made ver...
