Drawings

In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings used in the description of the embodiments or the prior art will be briefly described below, it is obvious that the drawings in the following description are only some embodiments of the present invention, and for those skilled in the art, other drawings can be obtained according to these drawings without creative efforts.

Wherein:

fig. 1 is a schematic structural view of a motorcycle tail box cover in one embodiment.

Fig. 2 is a schematic view of the motorcycle tail box cover shown in fig. 1 from another perspective.

In the figure:

100. a box cover; 110. a bass playback port; 120. a bass channel; 130. a high-sound playing port; 140. a high pitch channel; 150. a reinforcing structure; 160. a connecting portion.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

Referring to fig. 1 and 2, as a specific embodiment of the present invention, a motorcycle tail box cover is used to connect with a box body, and a sound box with a bass generator and a treble generator is placed in the box body. Its use scene should not be restricted to the motorcycle rear box, and the audio amplifier device on other mobile devices also can be suitable for the utility model provides a case lid 100.

The main body is a box cover 100, and a bass playing port 110, a treble playing port 130, a bass channel 120 and a treble channel 140 are arranged on the box cover 100. Wherein, two ends of the bass channel 120 are respectively communicated with the bass generator and the bass playing port 110, and two ends of the treble channel 140 are respectively communicated with the treble generator and the treble playing port 130.

Therefore, the high-pitch frequency band and the low-pitch frequency band are played from different channels respectively and are independent of each other, interference is reduced, and the high-pitch presenting effect is better.

Further, the treble passage 140 gradually increases in diameter from the treble generator to the treble playing port 130 in a gradually expanding state to perform a volume amplification function.

Alternatively, the bass passageway 120 may also gradually increase in diameter from the bass generator to the bass playback port 110, in a diverging state. The arrangement principle is the same as that of the treble channel 140, and the treble channel plays a role in amplifying the volume.

As shown in fig. 1 and 2, the bass passageway 120 and the treble passageway 140 extend from the inside of the cabinet toward the outer surface of the cabinet cover 100, and a large and a small two-conical-surface protrusion is formed along the surface of the cabinet cover 100.

Specifically, the adjacent sides of the two conical surface bulges are abutted and extend forwards side by side.

Correspondingly, the bass playing port 110 and the treble playing port 130 are two independent openings disposed on the box cover 100, and are not communicated with each other, so as to avoid interference between the low frequency sound waves and the treble sound waves.

Alternatively, the extended length of the bass channel 120 is longer than the treble length, so that the propagation path of the low frequency sound wave is longer, and the amplification effect of the bass channel 120 on the sound wave is enhanced to make the bass effect presented louder without being boring. In contrast, treble channel 140 extends for a shorter length, reducing the sound amplification effect of treble channel 140 on sound waves-making the treble effect more crisp and less obtrusive.

Preferably, the extended length of the bass passageway 120 is 1.2 to 1.5 times the extended length of the treble passageway 140.

Each bass channel 120, each treble channel 140, each bass playback port 110, and each treble playback port 130 are used as a power amplifier unit, and each box cover 100 can be simultaneously provided with two or more power amplifier units to correspond to different positions or multiple sound generators on the same sound box.

Optionally, the power amplifier units are symmetrically distributed on the case cover 100.

In one embodiment, a reinforcing structure 150 is further provided on the cover 100.

Alternatively, the reinforcing structure 150 may be any structure such as a connecting rib, a groove protruding or recessed on the panel, etc., and can play a role in connecting and positioning while increasing the strength of the box cover 100.

Optionally, the cover 100 is further provided with a connecting portion 160 for connecting the cover.

Further, a sealing device is disposed at the connection between the cover 100 and the cabinet to prevent the electrical structure of the speaker box from being damaged by water seepage from the interior.

The above disclosure is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the scope of the invention, which is defined by the appended claims.
