The outer wall of the bottom of the tweeter frame is provided with threads, the inner wall of the top of the center pillar is provided with threads, and the bottom of the tweeter frame is tightly combined with the top of the center pillar through the threads, so that the tweeter can be quickly and conveniently installed on the center pillar, firmness of the combination part of the tweeter and the center pillar is ensured, and the tweeter is particularly suitable for coaxial speakers for vehicle-mounted sound equipment.

Description

Thread type high pitch structure of coaxial loudspeaker

Technical Field

The utility model relates to a coaxial loudspeaker screw thread formula high pitch structure, specifically speaking are coaxial loudspeaker screw thread formula high pitch structure that is suitable for audio-visual equipment such as on-vehicle stereo set to use, belong to electro-acoustic technical field.

Background

In the prior art, a coaxial speaker applied to a vehicle-mounted sound system requires high sound pressure level, good sound quality and high reliability, and is generally arranged on a T iron of a woofer to form an acoustic structure design coaxially arranged so as to meet the requirement of the vehicle-mounted sound system speaker.

Traditional coaxial loudspeaker's high pitch generally adopts a long bolt, and T iron core post is run through earlier to screwed one end, passes the center pillar again, and it is downthehole to penetrate the bolt of the lower surface of high pitch basin frame bottom U iron at last, through rotatory bolt-up T iron, center pillar and high pitch basin frame. The mounting means of stay bolt causes the high pitch basin frame, center pillar and T iron core post to be crooked easily, and the straightness is difficult to be guaranteed that hangs down, and the efficiency is lower in mass production, and uses easily not hard up between the part for a long time, drops even. Still mounting means is through the lower surface at high pitch basin frame bottom U iron to and center pillar top upper surface scribbles the gluing agent, uses gluing agent bonding fastening center pillar and high pitch basin frame, but this kind of gluing agent curing time is longer, and also environmental protection, and has the risk that takes place to drop in jolting in-process high pitch basin frame and center pillar junction. There is a need for a mounting structure that facilitates quick and convenient mounting and ensures high reliability of the combination of the tweeter frame and the center pillar.

Disclosure of Invention

An object of the utility model is to overcome the not enough of existence among the prior art, provide a coaxial loudspeaker screw thread formula high pitch structure, its simple structure, simple to operate, the reliability is better.

According to the utility model provides a technical scheme: coaxial speaker screw thread formula high pitch structure including a woofer T iron, is provided with the center pillar on the stem of T iron, and the bayonet high pitch basin frame that is equipped with of center pillar inner wall, high pitch basin frame top outside cover are equipped with the protection casing.

Furthermore, the outer wall of the bottom of the tweeter frame is provided with an external thread, the inner wall of the top of the center post is provided with an internal thread, and the external thread of the tweeter frame is matched with the internal thread of the center post to complete assembly;

the middle column is tightly connected with the core column through bolts.

Further, the outer diameter of the outer wall where the external thread section at the bottom of the high pitch basin frame is located is smaller than the outer diameter of the inner wall of the middle column.

Further, the outer diameter of the outer wall of the center pillar is smaller than the outer diameter of the stem.

Further, the center pillar is made of aluminum.

Furthermore, the treble basin stand is made of plastic.

Compared with the prior art, the utility model, the advantage lies in: the utility model discloses simple structure is compact, and design benefit is reasonable, simple to operate, the good reliability. Through the setting of outer ledge in high pitch basin frame bottom and center pillar top inner wall screw thread, the installation effectiveness when having improved big batch assembly has improved the reliability at part joint position, also makes things convenient for the dismantlement to high pitch basin frame and center pillar when necessary, and the heat dissipation of two speakers of high, bass can also be improved in the design of center pillar at high-power during operation, improves the security of product, specially adapted coaxial speaker for the vehicle-mounted stereo set.
