乡音录音棚

制作「乡音录音棚」活动海报，采用 3:4 画布，面向普通社区参与者。唯一记忆点锁定为“话筒声纹末端变成地形等高线”，任何次级元素都不得改变它的阅读方向。选择偏心竖构图作为版式骨架，使视觉从主物自然过渡到文字。海报只保留四组文字：「乡音录音棚」「把参与变成可延续的方法」「桥下声场」「携带有线耳机」，标题仅允许一处边缘遮挡。辅物仅有分贝刻度、线缆弧线和吸音毡。使用蓝晒声谱叠加压凹波纹表现吸墨、压痕、折面和边缘磨损，配色限制为炭黑、象牙白、铜绿与珊瑚粉。低位工作灯从同一方向照亮主物，阴影软硬随距离变化。最终图像仅含招贴本身，裁切不碰关键信息，并为「乡音录音棚」的活动信息留足空间；不借品牌、明星、IP、HUD、二维码或奢华展示获取注意，保持「乡音录音棚」的公共活动语气。

Produce a 3:4 event poster for “Dialect Recording Booth,” aimed at ordinary community participants. Keep a microphone waveform ending as topographic contour lines as the one memorable idea and prevent supporting elements from changing its reading direction. Choose an asymmetric vertical composition as the layout skeleton and move naturally from hero to text. Keep only four copy groups: “Dialect Recording Booth,” “Turn participation into a practice that can continue,” “the acoustic space beneath the bridge,” and “bring wired headphones.” The hero may cover one stroke edge only. Limit supporting matter to decibel marks, cable arcs, and acoustic felt. Use a cyanotype sound spectrum over debossed wave ridges for ink absorption, impressions, folds, and edge wear, with a palette of charcoal, ivory, verdigris, and coral pink. Illuminate from a low work lamp, allowing shadow softness to change with distance. Show only the placard, with essential information protected from trim. Use no brand, celebrity, IP, HUD, QR code, or luxury display shortcut. For the final rendering, keep the metaphor literal enough to be built and photographed: a microphone waveform ending as topographic contour lines. Let the transition cross one focal plane so the viewer can understand it immediately at poster distance. End the image at the printed edge, with no wall, frame, clip, or presentation shadow. Final art direction: editorial poster design with a disciplined grid and material-aware composition. Use this controlled palette as the dominant visual system: #F2EBDD, #243447, #C65D48, #D6A14B; preserve believable local material colors within it. Preserve the requested text hierarchy and wording as part of the design, but do not invent extra slogans, pseudo-text, logos, or watermarks. Keep one unmistakable primary subject or information route and one readable visual action. Use disciplined negative space and avoid default perfect symmetry. Physical credibility is mandatory: correct gravity, contact shadows, material thickness, tool weight, joint loading, fabric tension, liquid direction, reflections, scale, and occlusion. Create an original visual with no resemblance to a public figure, copyrighted character, existing campaign, or living artist signature style. No unrelated decorative icons, floating objects, duplicated limbs, plastic gloss, waxy skin, synthetic collage artifacts, or AI watermarks. Return exactly one finished image composed for 3:4; no variants, process sheet, split panels, mockup frame, or contact sheet.
