Problems solved by technology

The push-type operation of this type of external regulator 100 is relatively stiff and inconvenient to operate, and is limited by the counting range of the counter 124, so it is impossible to realize stepless adjustment of the volume. In particular, the number of presses of the buttons is limited and the service life is low.

Embodiment 1

[0037] see image 3 and Figure 4 , an external volume regulator, the external regulator is connected with the existing internal chip to form a volume control device, the external regulator is used to convert the mechanical action into an electrical signal and send the electrical signal to the internal chip, and the internal chip accordingly The signal adjusts the attenuation of the input audio in response, decreasing the volume by increasing the attenuation, or increasing the volume by decreasing the attenuation. Specifically, the external regulator 100 mainly includes a Hall IC130, a magnetic ring 140 and a knob 150, wherein: the Hall IC130 is connected to the internal chip for sending an electrical signal to the internal chip in real time; the magnetic ring 140 Corresponding to the Hall IC 130, the magnetic ring 140 has a plurality of magnetic poles arranged in a balanced manner, and the polarities of adjacent magnetic poles are opposite, that is, N poles and S poles are a...

Embodiment 2

[0042]In order to cooperate with the operation of the internal chip, the Hall IC 130 in the first embodiment is optimally designed in this embodiment. The technical solution disclosed in the first embodiment is not described here, and the technical solution disclosed in the first embodiment also belongs to this embodiment.

[0043] Such as Figure 5 As shown, in order to clearly show the difference technical features between this embodiment and Embodiment 1, only the magnetic ring 140 and the Hall IC 130 are shown in this figure, specifically: the Hall IC 130 includes two Hall elements, That is, the main component A and the auxiliary component B (one of them can be arbitrarily designated as the main component A, and the other is the auxiliary component B), the main component A and the auxiliary component B are located at different positions on the same circle, and the circle It is a concentric circle with the magnetic ring 140, so that the angular velocity and linear velocity ...

Abstract

The invention discloses an external volume regulator and an adjustment method. The regulator is used to output an electrical signal to an internal chip, and the internal chip adjusts the volume according to the electrical signal. The regulator includes a Hall IC, a magnetic ring and a knob. Wherein: the Hall IC is connected to the internal chip; the magnetic ring is set corresponding to the Hall IC, the magnetic ring has a plurality of magnetic poles arranged in a balanced manner, and the polarities of adjacent magnetic poles are opposite; The knob is fixedly connected with the magnetic ring for driving the magnetic ring to rotate, and the magnetic pole switching of the magnetic ring triggers the Hall IC to generate and output an electrical signal to the internal chip. The adjustment method of the external volume regulator provided by the invention does not have rheostats, counters and other components with a limited adjustment range, and can fully realize the stepless adjustment of the volume.

Description

technical field [0001] The invention relates to a volume adjustment device, in particular to an external regulator and an adjustment method for the volume adjustment device. Background technique [0002] see figure 1 and figure 2 , the existing volume adjustment device includes a hand-driven external regulator 100 and an internal chip 200 for attenuating the output audio. The external regulator 100 is mainly used to convert the mechanical action imposed by manpower into an electrical signal. It is used to identify the electrical signal and increase or decrease the attenuation of the output audio accordingly, thereby reducing or increasing the volume accordingly. [0003] The above-mentioned external regulator 100 is roughly divided into two types, ie, the knob type and the button type. in: [0004] see figure 1 , the knob-type external regulator 100 mainly includes a protruding knob 111 and a potentiometer 112. The potentiometer 112 is mainly composed of a rheostat ass...
