Description

Sound box panel structure

Technical Field

The utility model relates to an audio amplifier field, in particular to audio amplifier panel structure.

Background

A speaker refers to a device that can convert an audio signal into sound.

The sound box is a terminal of the whole sound system, which is used for converting audio frequency electric energy into corresponding sound energy and radiating the sound energy to the space, is an extremely important component of the sound system and is responsible for converting an electric signal into an acoustic signal for direct listening by ears of people.

At the design face of audio amplifier structure, integrated high pitch horn and bass unit on the audio amplifier panel, traditional audio amplifier panel, horn and bass single face are mostly mutual independent design, rely on the circuit to improve tone quality.

The design of the structure has the condition that the valley point connection is not even when the frequency response curves of the high-pitch horn and the bass unit are connected, and the condition can influence the tone quality of the sound box.

SUMMERY OF THE UTILITY MODEL

The utility model provides a solve above-mentioned problem, provide a sound box panel structure, through the setting of arc extension linkage segment between high pitch horn and the bass unit, improve the problem that the connection of frequency response curve valley point is uneven in physical connection, improve the tone quality of audio amplifier.

And moreover, due to the design of the echo hole, the low-frequency diving of the sound box is better.

In order to achieve the above object, the utility model discloses an audio amplifier panel structure, audio amplifier panel body include the high pitch horn of upside and the bass district of downside, the high pitch horn is equipped with a cambered surface downwards and extends linkage segment and bass district transitional coupling, and the upside is for being connected the face with the top that the panel contained angle is 0-45, and the left and right sides is connected the face for the side of symmetry, and central point puts to set up the end for the high pitch unit, and the directional high pitch unit of side connection face department of setting up still is equipped with the second order and connects the face.

Further, the included angle between the side end connecting surface and the horizontal plane is 45 degrees.

Furthermore, the two sides of the cambered surface extension connecting section are also provided with sound returning holes.

Furthermore, the thickness of the sound box panel is 5-9 mm.

To sum up, the utility model discloses possess following advantage:

the utility model discloses a setting of arc extension linkage segment between high pitch horn and the bass unit improves the not problem of tie of frequency response curve valley point connection on physical connection, improves the tone quality of audio amplifier.

Drawings

FIG. 1 is a schematic view of a panel structure of a sound box;

fig. 2 is a schematic cross-sectional view of a front panel of the cabinet.

Detailed Description

The invention will be further described with reference to the following drawings and examples:

example (b):

a panel structure of a sound box, as shown in fig. 1-2, comprising a sound box panel body 1.

On the arrangement of the sound box panel, the thickness of the sound box panel body 1 is 5-9 mm.

The speaker panel body 1 includes a high tone horn 2 on the upper side and a low tone area 3 on the lower side.

On the arrangement of the high pitch horn, the high pitch horn 2 is provided with a cambered surface extending connecting section 21 downwards to be in transition connection with the low pitch region 3 for connecting high and low pitches.

The upper side of the high pitch horn is a top connection surface 22 which forms an angle of 0-45 degrees with the panel, specifically, the top connection surface is vertically inward.

The angle is preferably 45 °.

The left side and the right side of the high pitch horn are symmetrical side end connecting surfaces 23, and the included angle between the side end connecting surfaces 23 and the horizontal plane is 45 degrees.

The central position is a treble unit set end 24 for the fixed connection of the treble unit.

It is noted that the lateral end connecting surface 23 is further provided with a second order connecting surface 25, which is directed to the treble unit setting end and has an angle of more than 45 ° with the horizontal plane, and is connected with the cambered surface extending connecting section.

The two sides of the cambered surface extension connecting section 21 are also provided with sound returning holes 4, and the sound returning holes are designed to enable the low-frequency diving of the sound box to be better.

Specifically, the treble unit setting end 24 is provided with a treble unit, and the connection hole of the circumference of the circular through hole of the bass region 3 is provided with a bass unit.

In sound radiation, the arrangement of the arc-shaped extending connecting section between the high-pitch horn and the bass unit improves the problem that the connection of valley points of a frequency response curve is not even in physical connection, and improves the tone quality of the sound box.

To sum up, this scheme improves the not problem of keeping flat of frequency response curve valley point connection in physical connection through the setting of arc extension linkage segment between high pitch horn and the bass unit, improves the tone quality of audio amplifier.
