Tuning structure of a sound mixer
View Patent ↗A tuning structure of a sound mixer is disclosed to include a switch set, formed of sliding switches with a respective switching lever, a face panel, which has sliding slots arranged in parallel for the passing of the switching levers of the switch set, a track set, which is mounted in between the switch set and the face panel and has pairs of ribs for guiding movement of the switching levers of the sliding switches stably along the sliding slots of the face panel, and tuning keys respectively fastened to the switching levers of the switch set and suspending above the face panel.
1. A tuning structure used in a sound mixer, comprising:
a switch set, said switch set having a substrate, a plurality of sliding switches mounted on a top side of said substrate and arranged in parallel, and a plurality of switching levers horizontally movable along said sliding switches;
a face panel, said face panel having a flat panel body and a plurality of sliding slots cut through top and bottom sides of said flat panel body for the passing of said switching levers of said switch set;
a track set mounted in between said switch set and said face panel, said track set having a plurality of tracks fixedly fastened to the bottom side of said flat panel body of said face panel corresponding to the sliding slots of said face panel, said tracks each having guide means respectively fitted into the sliding slots of said face panel and a longitudinal sliding slot formed in said guide means for the passing of said switching levers of said switch set respectively; and
a plurality of tuning keys respectively fastened to said switching levers of said switch set and suspending above said face panel.
2. The tuning structure as claimed in claim 1 , wherein the guide means of each of said tracks of said track set has two longitudinal ribs arranged in parallel, and the longitudinal sliding slot of each of said tracks of said track set is defined between the two longitudinal ribs of the respective track.
3. The tuning structure as claimed in claim 2 , wherein said the longitudinal ribs of said tracks of said track set are respectively inserted into the sliding slots of said face panel.
4. The tuning structure as claimed in claim 3 , wherein said the longitudinal ribs of said tracks of said track set each have a retaining lip engaged into a respective locating groove on said face panel to secure said track set to said face panel.
5. The tuning structure as claimed in claim 1 , wherein said tracks of said track set each have a bonding surface respectively bonded to said face panel.
6. The tuning structure as claimed in claim 1 , wherein said track set further has a connecting member connected between each two adjacent tracks to join said tracks.
7. The tuning structure as claimed in claim 6 , wherein said connecting member has a plurality of breakable portions formed integral between each adjacent track and connecting member.
8. The tuning structure as claimed in claim 1 , wherein said tuning caps each have two retaining ribs respectively clamped on two sides of the associating switching lever.
9. The tuning structure as claimed in claim 1 , wherein said tuning caps each have at least one rib inserted into the associating sliding slot of said face panel and the associating sliding slot of said track set.
10. The tuning structure as claimed in claim 1 , further comprising a spacer member mounted in between said track set and said switch set for blocking the sliding slots of said track set against external objects, said spacer member having a plurality of narrow elongated crevices for the passing of said switching levers.
