Description

Technical Field

[0001] This utility model belongs to the field of loudspeaker technology, specifically relating to a loudspeaker array group. Background Technology

[0002] Traditional loudspeaker arrays often employ a simple combination of low-frequency and high-frequency units. This results in poor directivity in the low-frequency range, making it difficult to accurately control the sound field coverage, leading to energy waste and interference from reflected sound. Current technologies, while improving directivity by increasing the number of units, significantly increase system size, weight, and cost, placing high demands on building loads and limiting applicability. Therefore, there is an urgent need for a loudspeaker array that can improve low-frequency directivity while maintaining a compact structure. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a loudspeaker array that achieves strong directivity in both high and low frequency bands through modular design and specific arrangement, while reducing system size, weight, and cost.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a loudspeaker array group, comprising two matrix modules arranged longitudinally, with an adjustable angle of 10°-60° between the two matrix modules; each matrix module includes:

[0005] A vertical low-frequency acoustic array formed by four closely arranged low-frequency unit modules; and

[0006] Two columns of high-frequency modules are independently and vertically arranged on one side of the vertical low-frequency acoustic wave array; each column of high-frequency modules contains multiple high-frequency units.

[0007] Furthermore, a column of high-frequency modules is provided next to every two low-frequency unit modules of the matrix module.

[0008] Furthermore, the low-frequency unit module is a 10-inch low-frequency unit module.

[0009] Furthermore, each column of the high-frequency module contains ten high-frequency units; the two matrix modules are combined vertically to form an array containing eight low-frequency unit modules and forty high-frequency units.

[0010] Furthermore, it also includes a connecting plate, through which the two matrix modules are longitudinally connected.

[0011] Furthermore, the connecting plate is a rigid metal plate.

[0012] Furthermore, it also includes an angle connector, through which the adjustable included angle is achieved, and the angle connector is located at the mating end of the two matrix modules.

[0013] Furthermore, the high-frequency module operates in the frequency band of 2kHz-20kHz, and the low-frequency unit module operates in the frequency band of 100Hz-2kHz.

[0014] Furthermore, the high-frequency module adopts a horn-type design to enhance horizontal directivity.

[0015] Furthermore, the mounting holes of the low-frequency unit module are staggered from those of the high-frequency module to avoid acoustic interference.

[0016] Furthermore, the spacing between the high-frequency units of the high-frequency module is less than half the spacing between the low-frequency unit modules of the vertical low-frequency acoustic wave array.

[0017] The beneficial effects of this utility model are as follows: By arranging two matrix modules vertically to form an array containing eight low-frequency unit modules and forty high-frequency units, the high-frequency band has strong directivity, and the low-frequency band of 150Hz-2000Hz also has strong directivity, achieving precise coverage, long sound wave radiation transmission distance, and high sound reinforcement clarity. Each matrix module shares a single structure, achieving energy-saving, environmentally friendly, economical, and practical effects. Under the condition of good energy-saving and environmental protection, especially in the 100Hz-500Hz range, this structure, when used in an array, can effectively reduce the size of the client's sound reinforcement system, making it more economical. Especially when used in large-space environments, this product can precisely control the coverage and shape of the sound, effectively reduce the waste of sound energy, and avoid exciting unnecessary reflections and reverberation, making the sound reinforcement system clearer and the sound effect better. It also significantly reduces the size and weight of the product. When spliced ​​into a line source array speaker group, the overall load on the building is not excessive, which increases the applicability of the product and solves acoustic problems that were difficult to solve in the past, resulting in excellent performance.

[0022] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0023] like Figure 1 , Figure 2 , Figure 3 The speaker array shown includes two longitudinally arranged matrix modules 100, forming an adjustable angle of 10°-60° between them. This adjustable angle is achieved via an angle connector located at the mating end of the two matrix modules 100. The two matrix modules 100 are longitudinally connected by a connecting plate. The 10°-60° adjustable angle between the two matrix modules 100, facilitated by the angle connector, provides strong directivity, effectively reducing sound energy waste and avoiding unnecessary reflections and reverberation, resulting in clearer sound and better sound quality from the sound reinforcement system.

[0024] Each matrix module 100 includes: a vertical low-frequency acoustic wave array formed by four low-frequency unit modules 10 arranged closely and vertically; and two columns of high-frequency modules 20 arranged independently and vertically on one side of the vertical low-frequency acoustic wave array; each column of high-frequency modules 20 contains ten high-frequency units 21.

[0025] like Figure 2 As shown, four low-frequency unit modules 10 are located on the left side of the matrix module 100, and two columns of high-frequency modules 20 are located on the right side of the matrix module 100. Both columns of high-frequency modules 20 are located on the right side of the vertical low-frequency sound wave array formed by the four low-frequency unit modules 10 arranged closely and vertically.

[0026] The low-frequency unit module 10 is a 10-inch low-frequency unit module, which saves costs, is lightweight, and has good performance.

[0027] The speaker array group in this embodiment has the following advantages:

[0028] Enhanced low-frequency directivity: A vertical low-frequency sound wave array is formed by closely arranged vertical low-frequency unit modules 10, giving the low-frequency band (150Hz-2000Hz) strong directivity.
