Concentric glowing knob structure and loudspeaker with knob structure

Abstract

Disclosed are a concentric glowing knob structure and a loudspeaker with the knob structure. The concentric glowing knob structure comprises an upper casing, an encoder, a light source unit, a light guide ring unit and a knob. The upper casing is covered on a circuit substrate and comprises a first opening; the encoder is arranged on the circuit substrate and comprises a screw bar which is arranged outside the casing in a penetrating mode through a first opening and rotates the circuit substrate along the axis to enable the circuit substrate to generate control signals; the light source unit is fixed on the circuit substrate and comprises a plurality of luminous components; the light guide ring unit comprises an upper light guide ring and a lower light guide ring, wherein the lower light guide ring is tightly sleeved on the encoder and arranged outside the upper casing in a penetrating mode through the first opening and is provided with a second opening and at least one light channel, the screw bar is arranged outside the lower light guide ring in a penetrating mode through the second opening, the upper light guide ring is provided with a third opening, a light inlet face and a light outlet face and sleeved on the lower light guide ring through the third opening; and the knob is clamped on the screw bar and can be driven to generate control signals when the knob is rotated. By means of the concentric glowing knob structure and the loudspeaker with the knob structure, the light guide uniformity can be enhanced.

Description

technical field [0001] The invention relates to a knob structure and a sound, in particular to a concentric light-emitting knob structure and a sound with the knob structure. Background technique [0002] Car audio is the most important entertainment medium during driving. It can not only listen to the radio, listen to music with an external I-POD, but also watch DVDs. The most common way to operate car audio is to adjust the desired volume or channel through its buttons or knobs. However, when driving at night, there is no bright light source in the car due to safety considerations, so some buttons or knobs are not easy to identify. Lead to misuse, and even affect driving safety. [0003] For this reason, some car dealers integrate the button or knob function of the car audio into the multi-function steering wheel. In this way, the car owner can change the settings of the car audio more easily without leaving the steering wheel. However, the disadvantage of such a design ...

The most common way to operate car audio is to adjust the desired volume or channel through its buttons or knobs. However, when driving at night, there is no bright light source in the car due to safety considerations, so some buttons or knobs are not easy to identify. lead to misuse and even affect driving safety

[0003] For this reason, some car dealers integrate the button or knob function of the car audio into the multi-function steering wheel. In this way, the car owner can change the settings of the car audio more easily without leaving the steering wheel. However, the disadvantage of such a design is that if other passengers in the car want to change the setting, they still have to operate it through an unidentifiable button or knob

[0004] Therefore, some electronic buttons or knobs of car audio can provide the function of luminous lighting through the design of the light guide ring. However, such electronic buttons or knobs are often deviated from the centrality due to the accumulated tolerances in the assembly process, which affects the transparency. The uniformity of light also greatly reduces the lighting effect, so there is a need to improve the light transmission design of electronic buttons or knobs
