Description

Technical Field

[0001] This utility model relates to the field of audio positioning technology, specifically to an omnidirectional positioning device with adjustable pitch angle. Background Technology

[0002] Audio positioning technology uses sound signals for location. An audio transmitter emits a sound signal, and a receiver receives the signal and uses algorithms to analyze it, thereby calculating the relative position of the transmitter and receiver. Therefore, the transmitter needs to ensure that the sound signal can cover as much space as possible.

[0003] Because loudspeakers emit sound directionally, multiple single loudspeaker devices facing different directions are often needed at a single location to ensure sound signals are received from all directions. This increases costs and is aesthetically unappealing. Furthermore, at some locations, interference or specific orientations may prevent loudspeakers from emitting sound in a particular direction. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide an omnidirectional audio positioning device with adjustable pitch angle and coverage. By optimizing the audio positioning structure design, omnidirectional audio signal coverage is achieved, reducing the number of devices required, shortening the implementation and debugging time, and reducing construction costs. When using audio positioning equipment, audio signals need to be emitted in a 360-degree direction at the center point. If it is a traditional single speaker device, four devices need to be deployed to ensure 360-degree sound emission. However, the audio positioning device of this utility model only needs to be deployed once, which greatly reduces the number of devices required.

[0005] To solve the above-mentioned technical problems, according to one aspect of the present invention, the present invention provides the following technical solution: an omnidirectional positioning and covering audio positioning device with adjustable pitch angle, comprising a housing, the housing being a polyhedron, and a corner being provided between two adjacent sides of the housing, and a speaker bracket being fixed at the corner, and a speaker being mounted on the speaker bracket.

[0006] As a preferred embodiment of the omnidirectional positioning and audio positioning device with adjustable pitch angle described in this utility model, a circuit module is provided inside the housing, and the circuit module is used to individually control each speaker.

[0007] As a preferred embodiment of the omnidirectional positioning and audio positioning device with adjustable pitch angle described in this utility model, the speaker bracket has multiple adjustable pitch angles, and the pitch angle is the angle between the speaker and the horizontal plane, ranging from 0 to 120 degrees.

[0008] As a preferred embodiment of the omnidirectional positioning and audio positioning device with adjustable pitch angle described in this utility model, a fixed column is provided on the inner side of the corner, and the speaker is connected to the fixed column through a speaker bracket.

[0009] As a preferred embodiment of the omnidirectional positioning and audio positioning device with adjustable pitch angle described in this utility model, it further includes a sound-transmitting hole, which is opened at the corner.

[0010] As a preferred embodiment of the omnidirectional positioning coverage audio positioning device with adjustable pitch angle described in this utility model, four corners are provided, and the four corners are distributed at the four corners of the outer shell.

[0011] As a preferred embodiment of the omnidirectional positioning and audio positioning device with adjustable pitch angle described in this utility model, locking screws and nuts are respectively provided on both sides of the speaker bracket.

[0012] In a preferred embodiment of the omnidirectional positioning and audio positioning device with adjustable pitch angle described in this utility model, the speaker is inserted into the speaker bracket and the speaker is locked in place by locking screws and nuts.

[0013] Compared with the prior art, the advantages of this utility model are:

[0014] By optimizing the design of the audio positioning structure, omnidirectional audio signal coverage is achieved, reducing the number of deployments, shortening the implementation and debugging time, and reducing construction costs. When using audio positioning equipment, audio signals need to be emitted in a 360-degree direction at the center point. If it is a traditional single speaker device, four devices need to be deployed to ensure 360-degree sound emission. However, with the audio positioning device of this utility model, only one device needs to be deployed, which greatly reduces the number of deployments. Attached Figure Description

However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0023] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not adhering to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model.

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0025] This invention provides an omnidirectional audio positioning device with adjustable pitch angle and coverage. By optimizing the audio positioning structure design, it achieves omnidirectional audio signal coverage, reduces the number of devices required, shortens the implementation and debugging time, and lowers construction costs. When using audio positioning equipment, it is necessary to emit audio signals in a 360-degree direction at the center point. If it is a traditional single-speaker device, four devices need to be deployed to ensure 360-degree sound emission. However, the audio positioning device of this invention only requires one device, which greatly reduces the number of devices required.

[0026] Figures 1-4 The diagram shown is an overall structural schematic of an embodiment of the audio positioning device with adjustable pitch angle and omnidirectional positioning coverage according to this utility model. Please refer to [link / reference]. Figures 1-4 The main structure of this embodiment includes a shell 1, which is a polyhedron, and a corner 5 is provided between two adjacent sides of the shell 1. A speaker bracket 4 is fixed at the corner 5, and a speaker 3 is mounted on the speaker bracket 4.

[0027] The outer casing 1 contains a circuit module 2, which is used to control each speaker 3 individually. The speaker bracket 4 has a multi-position adjustable tilt angle, which is the angle between the speaker 3 and the horizontal plane, ranging from 0 to 120 degrees. A fixing post 6 is provided on the inner side of the corner 5, and the speaker 3 is connected to the fixing post 6 through the speaker bracket 4. It also includes a sound-transmitting hole 7, which is opened on the corner 5.

[0028] In practical use, each corner 5 of the outer casing 1 has the same size, shape and angle. Each speaker 3 is fixed on the speaker bracket 4, and then fixed to each corner 5 of the outer casing 1 through the speaker bracket 4. Each speaker 3 is individually connected to the circuit module 2 and can be switched on and off individually or controlled in a time-sharing manner. The speaker bracket 4 can adjust the pitch angle in multiple positions, thereby realizing the pitch angle adjustment function of the speaker 3.

[0029] The outer shell 1 is symmetrical, with rounded transitions at its corners 5. The curvature of each corner 5 is the same. A fixing post 6 is designed on the inner side of the corner 5, and a sound-transmitting hole 7 that conforms to the design of the sound cavity is designed on the corner 5.

[0030] The speaker 3 is connected to the fixed column 6 via the speaker bracket 4. The speaker bracket 4 can adjust the pitch angle, and can be adjusted in multiple positions within a fixed range. The angle of the speaker 3 changes with the angle of the speaker bracket 4, thereby achieving the purpose of adjusting the pitch angle.

[0031] Circuit module 2 controls each speaker 3 individually, and can be switched on and off independently or controlled in a time-sharing manner.

[0032] The housing 1 uses a speaker bracket 4 with multiple adjustable pitch angles to fix the speaker 3, achieving adjustable speaker pitch angles to adapt to different implementation environments and installation heights. In typical commercial settings, ceiling mounting is often used, where the installation height is normal. Adjusting the speaker bracket 4 to a large pitch angle, such as around 85 degrees, maximizes signal coverage while maintaining audio signal strength. In large exhibition halls or transportation hubs, where ceiling heights are high, suspended ceiling mounting is often used. However, considering the safety and aesthetics of the mounting rods, the installation height is still significantly higher than normal, resulting in a longer audio signal propagation distance. Therefore, adjusting the speaker bracket 4 to a small pitch angle, such as 45 degrees, shortens the audio signal propagation distance while maintaining audio signal strength.

[0033] Furthermore, locking screws 4-1 and nuts 4-2 are respectively provided on both sides of the speaker bracket 4;

[0034] In actual use, the speaker 3 is inserted into the speaker bracket 4 and locked in place by the locking screw 4-1 and nut 4-2; this is how the speaker 3 is installed.

[0035] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
