Is there any special name for a $n$-torus made by products of hyperspheres?

I was wondering if there exist an accepted name for an $n$-torus made by the product of hyperspheres $\mathbb{S}^d$, that is for the following set: $$\mathbb{S}^d\times\stackrel{n}{\cdots}\times\mathbb{S}^d=\left\{(\mathbf{x}_1,\ldots,\mathbf{x}_n)\in\mathbb{R}^{n(d+1)}: \mathbf{x}_i=(x_{1,i},\ldots,x_{d+1,i}), ||\mathbf{x}_i||_2=1, i=1,\ldots,n \right\}.$$ Any topologists in the room?

• I'd say "generalized torus" and give the definintion you've given; I've never heard of another name, but perhaps someone else has. – John Hughes Sep 16 '14 at 15:22
• Don't call it an $n$-torus. It's a product of spheres. – Qiaochu Yuan Sep 16 '14 at 15:24
• @Travis, all right, so I will drop the "$n$-torus" terminology and go with "generalized torus" if there is not a more exact term available. – epsilone Sep 16 '14 at 15:41

When $d = 1$, this is often called a flat ($n$-)torus. We say this because the metric induced on it by the ambient Euclidean space $\mathbb{R}^n$ is (locally) flat---by contrast, this is not the case for any $2$-torus embedded in $\mathbb{R}^3$. Note, though, that this is a statement about the metric geometry on the space, not the topology, where there is no such distinction.
For general $d$, one might call this an $n$-fold product of $d$-spheres. Anyway, as Qiaochu Yuan writes, you certainly shouldn't call this product an ($n$-)torus (when $d > 1$), as it would surely lead to confusion.
