Description

Technical Field

[0001] The utility model relates to the technical field of loudspeakers, in particular to a linear sound source structure of a professional loudspeaker system. Background Technique

[0002] Loudspeaker technology is one of the important technologies in the audio field, and its function is to convert electrical signals into sound output. The development of loudspeaker technology has experienced many years of evolution, from the initial mechanical loudspeakers to modern electromagnetic loudspeakers and electric loudspeakers. Traditional professional sound reinforcement loudspeaker systems use a single common baffle. For details, see the appendix Figure 1 ., the horn depth of the horn-type high-frequency unit is much greater than the cone depth of the low-frequency unit. Since the sound speeds of the high and low frequencies are the same, the low-frequency sound will inevitably reach the listening area later, which will cause peaks and valleys that should not exist in the frequency response curve due to the superposition characteristics of waves. The traditional method is to use a crossover to correct the phase difference caused by the position difference to the greatest extent, but this correction is limited and can only correct the position of one point at the crossover of the high and low segments. For details, see the appendix Figure 2 ., the performance of the loudspeaker is affected, which affects the overall loudspeaker effect and experience.

[0003] Therefore, it is necessary to develop a linear sound source structure for professional loudspeaker systems. Summary of the Invention

[0004] The purpose of the utility model is to provide a linear sound source structure for a professional loudspeaker system to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A linear sound source structure of a professional loudspeaker system, including a box body, a high-frequency loudspeaker is installed on one side above the inside of the box body, a low-frequency loudspeaker is installed on one side below the inside of the box body, and a high-frequency baffle is installed on one side of the high-frequency loudspeaker;

[0006] A low-frequency baffle is installed on one side of the low-frequency loudspeaker.

[0007] Preferably, a frame A is installed at one end of the high-frequency loudspeaker, and a diaphragm A is arranged on the inner wall of the frame A.

[0008] Preferably, a frame B is installed at one end of the low-frequency loudspeaker, and a diaphragm B is arranged on the inner wall of the frame B.

[0009] Preferably, a connecting plate A is installed below the outer wall on one side of the high-frequency baffle, and the outer wall on one side of the high-frequency baffle and the outer wall on one side of the low-frequency baffle are fixedly connected through the connecting plate A.

[0010] Preferably, a connecting plate B is installed below the outer wall on one side of the low-frequency baffle, and the bottom of the connecting plate B is fixedly connected to the bottom end inside the box body.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0012] By installing the high-frequency baffle at the chassis A of the high-frequency speaker and installing the low-frequency baffle at the chassis B of the low-frequency speaker, and making the installation positions of the high-frequency baffle and the low-frequency baffle in a front-back state to form a stepped manner. Solving the problem of the traditional common baffle, such a designed stepped manner converts the time difference of sound pulses into a distance difference, and pre-corrects the height difference of the high and low units physically, so there will be a minimum initial phase difference between the high and low segments, and there is a wide range of phase coincidence in a large area before and after the crossover point, which can be achieved without the need for crossover debugging. The crossover debugging is no longer cumbersome, reducing the workload of the debugging personnel, and increasing the overall performance of the speaker system, improving the use effect and experience of the speaker.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0021] The present utility model provides the following technical solution: a linear sound source structure for a professional loudspeaker system. Please refer to Figures 1-6 , which includes a cabinet 1. Above one side inside the cabinet 1, a tweeter 2 is installed. Below one side inside the cabinet 1, a woofer 3 is installed. One end of the tweeter 2 is equipped with a chassis A 4, and a diaphragm A 5 is arranged on the inner wall of the chassis A 4. One end of the woofer 3 is equipped with a chassis B 6, and a diaphragm B 7 is arranged on the inner wall of the chassis B 6. A tweeter baffle 8 is installed on one side of the tweeter 2;

[0022] A woofer baffle 9 is installed on one side of the woofer 3. Below the outer wall of one side of the tweeter baffle 8, a connecting plate A 10 is installed. The outer wall of one side of the tweeter baffle 8 and the outer wall of one side of the woofer baffle 9 are fixedly connected through the connecting plate A 10. Below the outer wall of one side of the woofer baffle 9, a connecting plate B 11 is installed. The bottom of the connecting plate B 11 is fixedly connected to the inner bottom end of the cabinet 1.

[0023] Working principle: When using the present utility model, the tweeter baffle 8 is installed at the chassis A 4 on the tweeter 2, and the woofer baffle 9 is installed at the chassis B 6 on the woofer 3. According to the front-back state of the installation positions of the tweeter baffle 8 and the woofer baffle 9, it forms a stepped manner, solving the problem of traditional common baffles. In such a designed stepped manner, based on the conversion of the sound pulse time difference into a distance difference, the height difference between the high and low units is pre-corrected physically, so there will be a minimum initial phase difference between the high and low segments, and there is a wide range of phase coincidence in a large area before and after the crossover point. During this period, it can be achieved without the need for crossover adjustment. The crossover adjustment is no longer cumbersome, reducing the workload of the debugging personnel, and increasing the overall performance of the loudspeaker system, improving the use effect and experience of the loudspeaker. At the same time, this technology can be extended and adapted. For details, please refer to Figure 6 , specifically Figure 6 The bottom end of the first tweeter baffle 8 can be chamfered. The woofer baffle 9 is fixed to the cabinet 1, and the connecting plate B 11 can be not used for fixation to reduce costs. The bottom end of the second tweeter baffle 8 is in a normal right-angle state. The woofer baffle 9 is fixed on the cabinet 1. The connecting plate A 10 between the tweeter baffle 8 and the woofer baffle 9 can have a certain length, and the length data can be set according to the later high and low frequency phase difference data. The connecting plate A 10 between the third tweeter baffle 8 and the woofer baffle 9 is in an inclined state, and the bottom end of the tweeter baffle 8 needs to match the inclination angle of the connecting plate A 10 to improve the overall aesthetics. The connecting plate A 10 between the fourth tweeter baffle 8 and the woofer baffle 9 is in an inclined state, and the connecting plate B 11 between the woofer baffle 9 and the cabinet 1 is inclined and fixedly arranged, making it meet the aesthetics and also enhancing its strength, reducing the occurrence of collision damage.
