Abstract: For a manifold $ N$ embedded inside euclidean space $ \mathbb{R}^{n+1}$, we produce a coloured operad that acts on the space of maps from $ N$ to $ M$, where $ M$ is a compact, oriented, smooth manifold. Our main example of interest is $ N$, the unit sphere, and we indicate how this gives homological actions, generalizing the action of the spineless cacti operad and retrieving the Chas-Sullivan product by taking $ N$ to be the unit circle in $ \mathbb{R}^2$. We go on to show that for $ S^n$, the unit sphere in $ \mathbb{R}^{n+1}$, the operad constructed is a coloured $ E_{n+1}$-operad. This $ E_{n+1}$-structure is finally twisted by $ SO(n+1)$ to homologically agree with actions of the operad of framed little $ (n+1)$-disks.
