Portable sound box with bass multiplier

Abstract

The invention provides a portable sound box with a bass multiplier device, which aims to realize bass enhancement of a small-size sound box, and designs the same-direction layout of pronunciation of a high-pitch unit and the bass multiplier device so as to meet the requirements that the sound quality of the portable sound box is more unified and powerful, and the portable sound box is more concise and attractive in appearance and more convenient to use. The portable sound box also has the waterproof function and the sound box body damping function to meet different use scenes, and the sound box hanging rope is provided with the quick connecting buckle so that the sound box can be conveniently hung on different supporting bodies to be used.

Description

Technical Field:

[0001] The present invention belongs to the technical field of electronic devices, and particularly relates to an electroacoustic multiplication device. Background Art:

[0002] Portable speakers are a widely used type of music-playing electronic product. They are small and easy to carry, and can provide a comfortable music experience in various scenarios. Currently, such products have a shortcoming of poor bass, and the present invention can well strengthen this shortcoming for small-sized speakers. Summary of the Invention:

[0003] The present invention aims to provide a portable speaker with a bass multiplication device and a co-directional design for high and low sound output. The bass multiplication utilizes a device formed by adding a diaphragm array body with a grid structure on the diaphragm of a bass speaker and connecting it to a front corrugated diaphragm. The combination of this bass multiplication device with the inner housing, outer housing, and radiation diaphragm of the speaker can achieve bass multiplication. The co-directional design of high and low sound output is achieved by a high and low sound distributor that acts on the radiation diaphragm at the rear end of the speaker with the sound pressure in the low sound unit cavity to achieve sound pressure balance, and the high sound of the built-in high sound speaker is output in the same direction through the distributor and the sandwich gap between the inner housing and the outer housing of the speaker.

Specific implementation method:

[0006] Fix the bass multiplier device on the divider conductor, fix the tweeter on the battery loading compartment support, connect and fix the divider conductor to the battery loading compartment, then connect and fix it to the circuit board loading compartment. Install the bass device end of the connection body into the speaker inner housing, and then install the whole into the speaker outer housing. Install the lanyard in place and fix it by hot melt adhesive process. Fix both ends with a tightening screw ring. Install the rear cover with a radiation diaphragm, buttons, and Type-C female plug can be encapsulated by hot melt adhesive process. The front grille has a threaded structure and will be directly embedded and fixed with the internal thread of the speaker outer housing.

[0007] Beneficial effects:

[0008] With the addition of the bass multiplier device, this portable speaker has excellent bass performance. At the same time, under the design layout of the same-direction output of high and low frequencies, the high and low frequencies are more concentrated and powerful, and the appearance is more delicate and beautiful.
