Boombox with 6 Built-In Songs - Speakers Pulse to the Beat | VRChat

A retro boombox with a carry handle. Pick a song in the menu and it plays from the boombox.

The speaker cones move on every beat, the cassette reels turn, and the display shows the song name, the play time and a bar graph that jumps with the beat.

There are 6 songs (Chill, City Night, Dance, Cafe, 8-Bit Game, Sleep). Each is about 2 min 15 s and loops without a gap.

Features

• 6 built-in songs: Chill (85 BPM), City Night (112), Dance (124), Cafe (100), 8-Bit Game (150), Sleep (70)
• The speaker cones move on the beat (matched to each song's tempo)
• Cassette reels turn; the display shows the song name, play time and beat bars
• Volume dial. The sound comes from the boombox and fades with distance (up to 15 m)
• 2 colors: Silver (black panel, orange display) / Mint (cream panel, light blue display)
• Modular Avatar ready: put it under your avatar and fit it to the right hand

Menu (English menu prefab)

• Boombox > Show: boombox on/off
• Boombox > Song: pick one of 6 songs to play (1 Chill, 2 City Night, 3 Dance, 4 Cafe, 5 8-Bit Game, 6 Sleep); press the playing song again to stop
• Boombox > Volume: volume (0-100%)

What's included

• Prefabs x 2 colors (body, speakers, reels, window, display)
• FBX, textures, lilToon materials, display shader, song animations
• 6 songs (for playback in the boombox only; see below)
• English-menu prefabs (_EN) next to the Japanese-menu prefabs. Use one or the other on an avatar, not both.
• Instruction manual and Terms of Use in English and Japanese

Specs

• Added to your avatar (counted in Unity): 11,966 triangles, 7 meshes, 7 material slots (body, 2 speaker cones, 2 reels, window, display; 3 kinds of materials), 0 PhysBones, 6 Audio Sources
• Synced parameters: 17 bits (Show 1, Song 8, Volume 8)
• All counts follow VRChat's rules (hidden parts are counted too) and show how much one prefab adds to your avatar.
• The VRChat performance rank depends on the total with your avatar, so this item alone does not decide it.
• Songs: 6, about 2 min 15 s each, compressed to mono, about 7 MB in total

Requirements

• Unity 2022.3.22f1 (an avatar project made with VRChat Creator Companion)
• VRChat SDK (Avatars) 3.10 or later
• Modular Avatar 1.18 or later
• lilToon 2.3 or later

Please note

• PC only. Not supported on Quest / Android.
• Songs play from the beginning. Someone who arrives later hears the song from the beginning at the moment they see it, so the position in the song can differ a little between people.
• People who have turned down or muted avatar audio will not hear it.
• No hand pose is included.
• The built-in songs are original songs made with ElevenLabs Music (an AI music generator, paid plan).
• The menu controls (Show, Song, Volume), the music and the display move only inside VRChat (including Build & Test) or with Gesture Manager. If they look still in the Unity Editor, nothing is broken.

Terms of use

• You may upload it to VRChat and similar services on your own avatars, edit it, and use it in streams, videos and photos (commercial or not).
• You may not redistribute, resell or share the data (edited or not), or use it to train AI.
• Full text: TermsOfUse_EN.txt in the download (Japanese original: TermsOfUse_JA.txt).

Update history

• v1.2 (2026-10-13): Uploads without pressing Auto Fix in VRChat SDK 3.10 (fixed texture Streaming Mip Maps, mesh Read/Write, Legacy Blendshape Normals). Turned on Load In Background for the songs. The shaders support Single Pass Instanced rendering in VR (the look outside VR is unchanged). Manual and description updated (counts are now what the item adds to your avatar, measured in Unity; how it looks in the Editor). The included documents now have English-only file names. The GUIDs are the same as before, so importing it over the old version replaces it.
• v1.1: English-menu prefabs (_EN) and English documents
• v1.0: First release

About the built-in music

• The songs were generated with AI (ElevenLabs Music, paid plan).
• They may be used only as part of this boombox. Extracting, redistributing or selling the audio files, or using them as BGM or material elsewhere, is not allowed. Details: BuiltinMusicLicense_EN.txt in the download.

How this was made (AI-Assisted)

The 3D shapes, materials, shaders and texts of this item were made with scripts written with AI assistance. A person checked how it looks and moves in Unity before release. The six built-in songs were generated with AI (ElevenLabs Music, paid plan).
